Max Contraction is probably bullshit, Mike Mentzer could be my hero

So I looked at some Max Contraction videos. Can't say I am impressed. Extraordinary claims require extraordinary evidence, and I didn't see any evidence. Sure, I saw lots of ripped athletes pimping the system, but all of them gained most of their muscle using traditional methods of lifting. They only switched to using the MC system later, probably once the camera started rolling. The Max Contraction system also fails the old science rule.

The chance that someone created a revolutionary but unproven way of doing something recently are inversely proportional to the chance that someone has already figured out an adequate way to do the same thing, which by definition of adequate has been proven to work.

I thus present to you:
Mike Mentzer

Yes that is a 70's/80's mustache. This guy is already dead. He is still revered as a body building God. Does he have the answer?

We shall see, and perhaps in a few months I will report back.

Training for an Olympic sized triathlon

I remember when I was a kid, my mother bought me a wrist watch for my birthday. On that watch was the word Ironman. I asked her what that meant and she said that it was the model of watch. Timex had named their model after the Hawaiian sport where insane endurance athletes swim 2.4 miles, bike 112 miles, and then finish all of that off with a good old fashioned marathon (26.2 mile run). As a fat little porker of a kid I had no comprehension that I would one day aspire to be an endurance athlete. I hated running, didn't like to go far on my bike, but I did enjoy swimming so long as there was a slide.

Training for three events plus lifting weights would be impossible with out knowing how to periodize workouts for maximum effectiveness which is why I would like to show everyone what an example of a balanced week of workouts looks like.

Note how each exercise is done three times a week with a day off in between, except for when there are two days off in between. No more then two exercises are done on a given day and two days of the week I only have one exercise. The most intense exercise is my full body weight lifting work out. While weight lifting it's important that I not over train, which is very easy to do while running, swimming, and biking. This is why I periodize my weight training.

Stage 1 is a light intensity I do each exercise with light effort. Often I will decrease the weights a full increment. I judge the intensity based on my ability to complete the last few repetitions in a set. Stage 2 is moderate, the last few reps are more difficult but my pace is steady and I still feel great after. Stage 3 is intense, my muscle are close to failure if they don't fail. I don't try to make them fail but I push hard to accomplish that last repetition which I tacked on because I knew I could do it.

There is also Stage zero which I do before I begin my 6 week cycle. Stage zero is very light intensity that I use to learn an exercise. The first week of performing an exercise you don't need to put much effort because your gains actually come from training your muscle memory. Since your muscle memory is not trained your more likely to hurt yourself trying to have an intense workout.

Your more likely to overtrain then you are to not train enough. Most people when they exercise want that awesome body NOW! The way they think they'll get it is by training hard.

No pain, No gain.
Pain is just weakness leaving the body.
Be all you can be.
I can't believe I bought this $1000 a year gym membership I hardly use it anymore, that's painful!

Over training is what causes you to lose interest in your exercise program. Signs of over training are:
  • Decreased performance.
  • Lack of motivation.
  • Poor coordination.
  • Loss of appetite.
  • Chronic muscle soreness.
  • Chronic stiffness at the joints.
  • Chronic headaches.
  • Longer recovery times.
  • Loss of concentration.
  • Reduced self esteem.
  • Depression.
http://www.healthguidance.org/entry/3524/1/How-To-Know-If-You-Are-Overtraining.html
Don't let that happen to you periodize your periodized workouts!

Running, Swimming and Biking together means that they have to share your gains. Notice how I only increase the distance or time of two of my exercises at once. This is of course ignoring the weight lifting which has it's own schedule. In addition to this I am always looking out for the signs of overtraining. If I feel like I have overtrained I take a day or two off and I might go back a week in each exercise.

Pf and Pe = Perception of food intake and Perception of exercise

Hunger and the rigors of exercise have an effect on our judgment of eating and physical activities. Only in the last few decades have we had the knowledge to account for all of the energy we store. Before food labels we had only had our hunger to tell us if we were burning more calories then taking in. Even worse, if you are starting to feel hungry it means that your metabolism, the vital component to burning fat is shutting down. Still worse your lack of protein will cause your body to start tearing the proteins it needs from your muscles. So before food labels you would have had no information unless your the sort that could experiment enough to learn what foods to eat and in what quantities.

It also makes sense that when people are asked how many calories they burned after a run they always project higher numbers. Exercising vigorously means you burn lots of calories right? Well we can't say that because the opposite can also be true. Anorexia is in part a problem of perception. First in the perception of what a healthy life style is, but also in that what little food they do eat they overestimate the number of calories consumed and under estimate the number of calories exercised. Lucky for us however we have such great scientific information at our disposal for knowing how many calories we burn doing any exercise.

Your perception of food intake is most likely flawed due to hunger. If you only eat two or three meals a day then your probably over eating, even though you probably feel hungry in the middle of the day. How is this possible? When you don't eat it drives your insulin down. Lack of insulin signals your hunger response, it also signals your muscles and organs to feed less (fewer calories burned), and your fat cells to store more (Gain fat). Now your body is in starvation mode. In starvation mode your hunger will increase as your insulin level decreases. This means that when it comes time for your meal time, you eat and eat and eat. Maybe it's that big plate of spaghetti or that McDonalds Double stack but you need more food to satisfy your hunger. Since your hungry you order the biggie size which brings the total calories to over 1100. Yet still, after your huge meal you'll still feel hungry, because it takes 20-30 minutes for your kidneys to start releasing insulin after cleaning the nutrient rich blood coming from your big mac. After the insulin starts flooding your system you'll get an energy high, you'll feel good, but 2 hours later even though your blood is filled with McDonalds your insulin starts coming down and all of those calories start getting sucked up into your fat cells. It's time to find a way count calories other then hunger.

The first tool I will discuss is calorie counting. I have already discussed how modern nutrition science allows food manufacturers to calculate the calories in their foods and print them on the packages. There are proprietary systems like weight watchers which have created very elaborate schemes based on this information to control food intake. The success of weight watchers is in part due to the fact that no one wants to spend an hour a day looking up the nutrient information in a book. Calorie counting used to be very problematic, one would have to have a dictionary sized book with data on all of the basic foods. The books couldn't hold all of the necessary information and searching through the pages in the book was time consuming. The best solution is to use a website, database program, or some form of metabolism measuring device such as the body bugg.

If you use Linux there is a program called NUT. NUT uses the SR-19 food database published by the US government and is a great system for keeping track of your calorie and nutrition. It has a simple search engine, and lots of data.

A more comprehensive on-line solution exists at www.my-calorie-counter.com This has the advantage that it's database is much more complete and updated more frequently then the SR-19, you can create meals and add new foods that it doesn't have, plus you can log your physical exercise. However, they charge a subscription fee to unlock certain necessary features. I subscribe and feel it's worth it.

The most expensive and fancy way of monitoring your caloric intake and exercise is the body bugg. The gadget keeps track of your total calories burned. This means you always know how many calories you can eat in a day. It can even show you a hourly breakdown of your metabolism using a simple bar graph. You could use the body bugg information to tailor your eating and workouts to burn the most fat.

Exercise is very similar to eating in that we lose sight of the actual caloric value of the work that we do. If someone has just run 6 miles they are likely to over estimate how much food they could eat to make up for the calories lost. Combine that with eating three meals a day and they will almost assurdly eat more then they burned. The opposite can also be true, many dieters completely ignore exercise and try and starve their way to being thin because they see little value in exercise or feel they can't do it. Later we will learn more about why exercise is MORE important then cutting calories in a weight loss program.

Sports medicine has created an important tool for calculating the number of calories burned in a certain exercise. Metabolic Equivalent units or METs is a measurable unit that has come from Sports research. The unit is measured by sampling how much oxygen an individual uses while performing a task such as running. One MET is defined as 3.5 liters of oxygen per kilogram of mass per 60 seconds. The reason this is a good system to remember is because it's universal. A small skinny woman doing a particular exercise has the same number of mets as a large fat man. This means that you can keep track of this simple number while you exercise and leave the complicated calorie counting to your computer at home. The calorie counting website I mentioned will automatically translate your met score into the number of calories burned. It also means that it's easier then some other methods which require you to keep track of your heart rate. It's important to make any exercise you do fun and plentiful, using heart rate measurment you could more accurately identify the number of calories you burn, but it may become tedious and lead to your dropping your fitness goals.

F = Food that you eat

One of the better things that the health sciences have produced is a basic understanding of the way our food is broken down and then built up into fat. As a result of this we derive the modern day calorie system which you can use to determine how much potential chemical energy your feeding on. Nutrition is an overarching term for all of the nutrients that make up food. The first three nutrients that everyone should know are the macro-nutrients: fat, protein, and carbohydrates.

Fats are lipids belonging to the sub classification triglycerides, other lipids include oils, waxes, and cholesterol. Lipids are hydrophobic meaning that they do not combine with water unless some other catalyst is added, such as soap. They play an important role in storing energy against a future energy deficit. Fat holds the highest chemical energy of the macro-nutrients and it's important to remember that all other macro-nutrients can be broken down and then rebuilt into fat.

http://en.wikipedia.org/wiki/Fat

Protiens are complex molecules that are created by life because they perform basic functions. You could think of them as the building blocks and tools of cells. They are made of amino acids which include the B vitamins, B1 through B12. Eating meat will give you all of the essentially B vitamins, and you can combine vegetables, grains, and nuts to achieve similar results. Protein has the highest overhead required to break them down into either energy or fat. This means that it will be beneficial to increase the amount of protein in our diets when trying to lose weight.

http://en.wikipedia.org/wiki/Protein

Carbohydrates are long chains of carbon also called saccharides or sugars. They are essentially the long term energy storage system for photosynthesis. Plants have varying degrees of carbohydrate use and this correlates to their metabolic value for humans. Plant material that is high in fiber and low in carbohydrates such as lettuce, bell pepper, or celery have fewer calories then fruits such as bananas, oranges and kiwi's.

http://en.wikipedia.org/wiki/Carbohydrate

All of the Macro-nutrients have a certain amount of chemical energy available to us through digestion.

Macro-nutrient KCal per gram
Fat 9-10 Kcal
Protein 4-5 Kcal
Carb 4-5 Kcal

When we want to lose weight, it's better to eat less fat and carbohydrates and more protein. The reason for this is that breaking down protein requires more overhead to break down then breaking down fat and sugar. However this is only part of our nutritional break down. You need fat in your diet because you'd be unable to function mentally without it. It's beneficial to have carbohydrates in your diet because exercise is arduous with a load of cream and fish in your stomach. I personally keep a percentage of 18-30% protein per day, little fat (10-20%), and the rest carbohydrates (45-60%). Start with a ratio of 50% carbohydrates, 30% protein, and 20% fat. If your losing weight then stick to your diet, if your having trouble running increase your carbohydrates, if your not gaining muscle increase your protein. I eat what I want but use feedback which I will talk about later to plan what I eat in advance. Another method I recommend is using the zone diet meal planning method. You can eat some of the foods you love while at the same time getting the protein that will help you feel satisfied. However if you want to be a super athlete then perhaps you'll want a more strict control.

http://www.zonediet.com/

You can lower the fat in your diet by eating lean fish and poultry. It's also important to have lots of variety in your foods. For instance a great meal is a cup of plain unsweetened yogurt and 2 cups of fruit. You can substitute oatmeal for the yogurt. When eating pizza you can substitute the cheese and tomato sauce for pesto sauce then add chicken and Parmesan cheese. Lean ham, whole grain pizza dough, and sauces made with olive oil or cheese substitute can also make your favorite foods more healthy. Finally no introduction to weight loss nutrition would be complete with out talking more about processed carbohydrates.

There are three sorts of carbohydrates, there are complex carbohydrates which include, chopped grains like oatmeal, and vegetables vegetables like green beans and brocoli. Processed carbohydrates tend to be white purified powders of the chemical energy that your body can break down; processed from the fruits, grains, and vegetables. These foods such as flour, sugar, and corn syrup have made food very cheap by increasing the calorie density at the sacrifice of the micro-nutrients and fiber. Simple carbohydrates include, Corn, Carrots and Potatoes. These foods are identifiable by their starchy or sweet nature, they include fruit and they all contain very little fiber. Generally for weight loss it's important to cut out Simple and Processed carbohydrates.

Logical argument is your tool for convincing sane people to be more sane.

How to Argue
A guide to examining the premises and logic of arguments - including a list of logical fallacies.
Steven Novella, MD

5/8/2006

Arguing is one of those activities most people do but few people do well. Many do not understand what a logical argument even is or how to do it correctly. Yet arguing is an essential skill of critical thinking. How we argue reflects how we think, how we evaluate our own conclusions, and how we challenge the beliefs of others.

Even the very purpose of arguing is often misunderstood. I have arguments almost every day. This does not mean I verbally fight with others on a daily basis, but rather I have discussions that involve either attempting to convince another of a specific conclusion, or resolving differing conclusions on a factual matter. In most of the arguments that I find myself the other person has staked out a position and they defend it jealously, as if they were a high-paid lawyer defending a client. This adversarial approach, however, is not constructive. Rather, the parties of an argument should be trying to find common ground, and then proceed carefully from that common ground to resolve any differences.

The beauty of a logical argument is that it is, well… logical. It is, in a way, like mathematics. In math 1+1 must =2. If there is a disagreement about this, it can be resolved objectively and definitively. If two people doing the same math problem come up with different answers, how should they respond? Should they each defend their answer at all costs. Or, should they examine each other’s solution to see if one, or both, might contain an error, and then resolve the error to see what the correct answer is?

Likewise, if two people have come to different conclusions about a factual claim, then one or both must be wrong. Both cannot be correct. That means that one or both must have made an error in the arguments they used to come to their conclusions. The two parties should work together to examine their arguments and resolve any errors.

Keep in mind, this only works if the arguments are about factual claims, not subjective feelings or value judgments. There is no objective way to resolve a difference of opinion regarding aesthetics, for example. You may prefer Mozart to Beethoven, but there is no way to demonstrate the aesthetic superiority of Mozart over Beethoven with facts or logic. It is very helpful, however, to identify when a conclusion contains an aesthetic opinion or a moral choice. It avoids arguing endlessly over an issue that is inherently irresolvable.

An excellent example of this is the abortion debate. Ultimately, all arguments over abortion come down to a personal moral choice: which should have greater value, the mother’s right to make choices regarding her own body, or the unborn fetus’s right not to be killed. All attempts to resolve this objectively have resulted in further arguments that are dependent upon value judgments, for example: at what point at or after conception does an embryo or fetus become a person? Also, how does the fetus’s total biological dependence upon its mother affect their respective rights? For this reason abortion is likely to remain a contentious issue, without a definitive resolution.

Structure of a Logical Argument

Whether we are consciously aware of it or not, our arguments all follow a certain basic structure. They begin with one or more premises, which are facts that the argument takes for granted as the starting point. Then a principle of logic is applied in order to come to a conclusion. This structure is often illustrated symbolically with the following example:

Premise1: If A = B,
Premise2: and B = C
Logical connection: Then (apply principle of equivalence)
Conclusion: A = C

In order for a conclusion to be considered valid all the premises of an argument must be true, and the logical connection must be valid. I use the term “valid” here specifically to refer to such conclusions, because a conclusion may still be “true” even if it is not valid. This is because it is possible to use wrong information, or faulty logic to reach a conclusion that happens to be true. An invalid argument does not necessarily prove the conclusion false. Demonstrating that an argument is not valid, however, removes it as support for the truth of the conclusion.

Breaking down an argument into its components is a very useful exercise, for it enables us to examine both our own arguments and those of others and critically analyze them for validity. This is an excellent way of sharpening one’s thinking, avoiding biases, and making effective arguments.


Examine your Premises

As stated above, in order for an argument to be valid all of its premises must be true. Often, different people come to different conclusions because they are starting with different premises. So examining all the premises of each argument is a good place to start.

There are three types of potential problems with premises. The first, and most obvious, is that a premise can be wrong. If one argues, for example, that evolutionary theory is false because there are no transitional fossils, that argument is invalid because the premise – no transitional fossils – is false. In fact there are copious transitional fossils.

Another type of premise error occurs when one or more premise is an unwarranted assumption. The premise may or may not be true, but it has not been established sufficiently to serve as a premise for an argument. Identifying all the assumptions upon which an argument is dependent is often the most critical step in analyzing an argument. Frequently, different conclusions are arrived at because of differing assumptions.

Often people will choose the assumptions that best fit the conclusion they prefer. In fact, psychological experiments show that most people start with conclusions they desire, then reverse engineer arguments to support them – a process called rationalization.

One way to resolve the problem of using assumptions as premises is to carefully identify and disclose those assumptions up front. Such arguments are often called “hypothetical,” or prefaced with the statement “Let’s assume for the sake of argument.” Also, if two people examine their arguments and realize they are using different assumptions as premises, then at least they can “agree to disagree.” They will realize that their disagreement cannot be resolved until more information is available to clarify which assumptions are more likely to be correct.

The third type of premise difficulty is the most insidious: the hidden premise. I have seen this listed as a logical fallacy – the unstated major premise, but it is more accurate to consider it here. Obviously, if a disagreement is based upon a hidden premise, then the disagreement will be irresolvable. So when coming to an impasse in resolving differences, it is a good idea to go back and see if there are any implied premises that have not been addressed.

Let’s go back to the transitional fossil example again. Why is it that scientists believe we have many transitional fossils and evolution deniers (creationists or intelligent design proponents) believe that we do not? This would seem to be a straightforward factual claim easily resolvable by checking the evidence. Sometimes evolution deniers are simply ignorant of the evidence or are being intellectually dishonest. However, the more sophisticated are fully aware of the fossil evidence and use a hidden premise to deny the existence of transitional fossils.

When a paleontologist speaks of “transitional” fossils, they are referring to species that occupy a space morphologically between two known species. This may be a common ancestor, in which case the transitional fossil will be more ancient than both descendent species; or it can be temporally between two species, the descendent of one and the ancestor of the other. But in reality we often do not know if the transitional species is an actual ancestor or just closely related to the true ancestor. Because evolution is a bushy process, and not linear, most of the specimens we find will lie on an evolutionary side branch. But if they fill a morphological gap in known species, they provide evidence of an evolutionary connection, and therefore qualify as transitional. For example, archaeopteryx may not be on the direct path to modern birds, but clearly they occupy a space that is transitional between therapod dinosaurs and modern birds and one of their close relatives is a direct ancestor to modern birds.

When evolution deniers say there are no transitional fossils their unstated major premise is that they are employing a different definition of transitional than is generally accepted in the scientific community. They typically define transitional as some impossible monster with half-formed and useless structures. Or, they may define transitional as only those fossils for which there is independent proof of being a true ancestor, rather than simply closely related to a direct ancestor – an impossible standard.


Logical Fallacies

Even when all of the premises of an argument are reliably true, the argument may still be invalid if the logic employed is not legitimate – a so called logical fallacy. The human brain is a marvelous machine with capabilities that, in some ways, still outperform the most powerful of super computers. Our brains, however, do not appear to have evolved specifically for precise logic. There are many common logical pitfalls that our minds tend to fall into, unless we are consciously aware of these pitfalls and make efforts to avoid them.

Because, as stated above, there is a tendency to start with desired conclusions and then construct arguments to support them, many people will happily draw upon logical fallacies to make their arguments. In fact, if a conclusion is not true one must either employ a false premise or a logical fallacy in order to construct an argument that leads to that conclusion. Remember, a valid argument cannot lead to a false conclusion. So in order to avoid using logical fallacies to construct invalid arguments, we need to understand how to identify fallacious logic.

Below I will list the most common logical fallacies, with examples of each. It is important to note that many claims may contain multiple logical fallacies at once. Also, some types of logic may fit into different types of fallacies simultaneously.

After reading many different lists of logical fallacies I have noticed that there is a “lumper vs splitter” difference among them. In other words, some lists may define logical fallacies in broad terms that may contain (lump together) many different specific subtypes. Other lists split the different subtypes into their own fallacies, even though the fallacious logic is essentially the same, or at least very similar. I am going to take a combined approach. I will stick to major types of logical fallacies, and then specifically name subtypes beneath them – those that might be found on other lists as separate entries.


Non-Sequitur
In Latin this term translates to “doesn’t follow.” This refers to an argument in which the conclusion does not necessarily follow from the premises. In other words, a logical connection is implied where none exists. This is the most basic type of logical fallacy, and in fact many of the fallacies listed below are also non-sequiturs but are an identifiable and common type.

Subtype: Magical Thinking
Magical thinking is perhaps the most common type of non-sequitur. The logical connection in these fallacious arguments are often a vague magical principle not based upon logic or evidence. For example, Feng Shui proponents might argue that it is better to place your bed in a certain position within your bedroom so that luck will flow into your home.


Argument from authority
The basic structure of such arguments is as follows: Professor X believes A, Professor X speaks from authority, therefore A is true. Often this argument is implied by emphasizing the many years of experience, or the formal degrees held by the individual making a specific claim. The converse of this argument is sometimes used, that someone does not possess authority, and therefore their claims must be false. (This may also be considered an ad-hominen logical fallacy – see below.)

In practice this can be a complex logical fallacy to deal with. It is legitimate to consider the training and experience of an individual when examining their assessment of a particular claim. Also, a consensus of scientific opinion does carry some legitimate authority. But it is still possible for highly educated individuals, and a broad consensus to be wrong – speaking from authority does not make a claim true.

This logical fallacy crops up in more subtle ways also. For example, UFO proponents have argued that UFO sightings by airline pilots should be considered valid because pilots are trained observers, are reliable characters, and are trained not to panic in emergencies. In essence, they are arguing that we should trust the pilot’s authority as an eye witness.

The argument from authority, or appeal to authority, has many potential subtypes, all of which invest authority in a particular group or situation. In the broadest sense this logical fallacy assumes that because a person or group possesses some positive quality (such as authority), their claims are true. Below are some examples of different types of positive qualities worth specific mention.

Subtype: Appeal to Common Belief
This fallacy is the argument that a claim must be true because many people believe it. It ignores the possibility, demonstrated frequently throughout history, that the majority can be completely wrong. The popularity of an idea or claim is often based upon features other than logic or evidence.

Subtype: Appeal to impending acceptance
I consider this to be a subtype to the argument from authority, because it attempts to invoke the authority of future belief and acceptance. Many peudosciences, such as creationism, ESP, and UFOlogy, claim that broad acceptance is right around the corner. This is a logical fallacy (the argument from authority) coupled with an assumed premise (that of future acceptance).

Subtype: Appeal to virtue or sincerity
This is the argument that a person or group possesses a virtue and therefore their claims must be true. For example, alternative medicine proponents often cite that a particular practitioner is very sincere and caring, and therefore claims for the efficacy of their treatment should be believed. Also, a credulous ghosthunter argued to me that an eyewitness who claimed to have seen someone levitate three feet off their bed should be believe because “why would she lie.”

Subtype: Argument from Conspiracy or anti-authority
This is the converse of the argument from authority, and basically states that a claim is false because it is held and promoted by an authority. This occurs often in the context that the official government position must be false because it’s the official government position. This is more properly considered a subtype of ad-hominem logical fallacy, arguing that the government must be wrong because they habitually lie or engage in cover-up conspiracies.


Appeal to Emotion
This fallacy is similar to the argument from authority, but I feel deserves a separate entry. Essentially this is any argument that a claim is true because it causes or is associated with positive emotions, or that its converse is associated with negative emotions. A common use of this fallacy is to justify belief in the existence of god. Many argue that god must exist because belief in god makes life worth living, or at least causes happiness and contentment. Also people might argue that they believe in an afterlife because they cannot deal with the alternative that death is final.


Argument from final outcome or consequences
Such arguments (also called teleological) are based on a reversal of cause and effect, because they argue that something is caused by the ultimate effect that it has, or purpose that is serves. This argument takes some permutation of the form that if a claim were either true or untrue, then the consequences would either be good or bad, and therefore what is true is what leads to either achieving a good outcome or avoiding a bad outcome.
For example, Christian creationists have argued that evolution must be wrong because if it were true it would lead to immorality.

Subtype: Argument from Benefit
Another common, and perhaps more subtle, form of this logical fallacy is the notion that if someone or some entity benefited from an event they must have caused the event. This fallacy is commonly invoked in the context of the JFK assassination in order to support an alleged conspiracy. The argument is that if someone benefited from the assassination of JFK they must have been involved in a conspiracy to carry out the assassination.

Subtype: Appeal to Fear
The appeal to fear is an argument from consequences, but in this case the consequences are individually relevant – an outcome to be personally feared. For example, proselytizers often argue that you should accept the claims of their religion for if you reject them you risk eternal damnation.

Subtype: Appeal to Flattery
Like the appeal to fear, this is a personalized version of the argument from final consequences, this time positive rather than negative. This logical fallacy is the attempt to convince someone of a claim because of implied flattery. For example, alleged psychics may support their claims of psychic abilities by claiming that they sense psychic potential in the person they are trying to convince.

Subtype: Appeal to Pity
This fallacy attempts to support a claim out of pity, sympathy, or even obligation to some person or group. For example, some proponents of Gulf War Syndrome have argued that we should accept the reality of this syndrome because we owe it to our veterans who fought for us in the Gulf War. Another example is the claim that silicone breast implants cause autoimmune disease, despite all evidence to the contrary. During this debate there were many appeals to pity for the victims of silicone breast implants. This can also be considered the fallacy of assuming the conclusion, because having sympathy for the victims of silicone breast implants assumes they are victims, which is the very matter of debate.


Post-hoc ergo propter hoc
This is perhaps the most common of logical fallacies. It follows the basic format of A preceded B, therefore A caused B, and therefore assumes cause and effect for two events just because they are temporally related (the Latin translates to “after this, therefore because of this”). This logical fallacy is frequently invoked when defending various forms of alternative medicine - I was sick, I took treatment A, I got better, therefore treatment A made me better. It is possible to have recovered from an illness without any treatment.

Keep in mind (as with the correlation and causation fallacy described below) it is possible that A did cause B. The logical fallacy is in assuming causation. It is still valid to argue for causation if there is independent evidence to support a causational relationship over other interpretations, such as coincidence.


Confusing correlation with causation
This is similar to the post-hoc fallacy in that it assumes cause and effect for two variables simply because they occur together. This fallacy is often used to give a statistical correlation a causal interpretation. For example, during the 1990’s both religious attendance and illegal drug use were on the rise. It would be a fallacy to conclude that therefore, religious attendance causes illegal drug use. It is also possible that drug use leads to an increase in religious attendance, or that both drug use and religious attendance are increased by a third variable, such as an increase in societal unrest, or even just population. It is also possible that both variables are independent of one another, and it is mere coincidence that they are both increasing at the same time.

This fallacy, however, has a tendency to be abused, or applied inappropriately, to deny all statistical evidence. In fact this constitutes a logical fallacy in itself, the denial of causation. This abuse takes two basic forms. The first is to deny the significance of correlations that are demonstrated with prospective controlled data, such as would be acquired during a clinical experiment. The problem with assuming cause and effect from mere correlation is not that a causal relationship is impossible; it’s just that there are other variables that must be considered and not ruled out a-priori. A controlled trial, however, by its design attempts to control for as many variables as possible in order to maximize the probability that a positive correlation is in fact due to a causation.

Further, even with purely epidemiological, or statistical, evidence it is still possible to build a strong scientific case for a specific cause. The way to do this is to look at multiple independent correlations to see if they all point to the same causal relationship. For example, it was observed that cigarette smoking correlates with getting lung cancer. The tobacco industry, invoking the “correlation is not causation” logical fallacy, argued that this did not prove causation. They offered as an alternate explanation “factor x”, a third variable that causes both smoking and lung cancer. But we can make predictions based upon the smoking causes cancer hypothesis. If this is the correct causal relationship, then duration of smoking should correlate with cancer risk, quitting smoking should decrease cancer risk, smoking unfiltered cigarettes should have a higher cancer risk than filtered cigarettes, etc. If all of these correlations turn out to be true, which they are, then the smoking causes cancer hypothesis is supported above other possible causal relationship and it is not a logical fallacy to conclude from this evidence that smoking probably causes lung cancer.


Special pleading, or ad-hoc reasoning
This is a subtle fallacy which is often difficult to recognize. In essence, it is the arbitrary introduction of new elements into an argument in order to jerry rig them, or fix them so that they appear valid. A good example of this is the ad-hoc dismissal of negative test results. For example, one might argue that ESP has never been demonstrated under adequate test conditions, therefore ESP is not a genuine phenomenon. Defenders of ESP have attempted to counter this argument by introducing the arbitrary premise that ESP does not work in the presence of skeptics. This fallacy is often taken to ridiculous extremes, and more and more bizarre ad hoc elements are added to explain experimental failures or logical inconsistencies.


Tu quoque
Tu quoque translates to “you too.” This is an attempt to justify wrong action because someone else also does it (two wrongs make a right). “My evidence may be invalid, but so is yours.” This fallacy is frequently committed by proponents of various alternative medicine modalities, who argue that even though their therapies may lack evidence some mainstream modalities also lack evidence.


Ad hominem
An ad hominem argument is any that attempts to counter another’s claims or conclusions by attacking the person, rather than addressing the argument itself. Taken broadly, this fallacy can be any argument that a person’s claims is false because of a negative quality possessed by the person. True believers will often commit this fallacy by countering the arguments of skeptics by stating that skeptics are closed minded. Skeptics, on the other hand, may fall into the trap of dismissing the claims of UFO believers, for example, by stating that people who believe in UFO's are crazy or stupid.

Sometimes this fallacy can be more subtle. For example, undesired research results can be dismissed because the researchers have an apparent conflict of interest. While true conflicts are a legitimate concern, the use of even minor potential conflicts to dismiss research finding a-priori is little more than an ad hominem logical fallacy.

Subtype – Argument from prior error
This form of ad hominem logical fallacy argues that the current claims of a person or group are incorrect because of errors committed in the past. Creationists, for example, often point to fossil frauds, or the discovery of living coelacanth previously thought to be extinct to counter the current evidence for evolution.


Ad ignorantum
The argument from ignorance basically states that a specific belief is true because we don't know that it isn't true. Defenders of extrasensory perception, for example, will often overemphasize how much we do not know about the human brain. It is therefore possible, they argue, that the brain may be capable of transmitting signals at a distance.
UFO proponents are probably the most frequent violators of this fallacy. Almost all UFO eyewitness evidence is ultimately an argument from ignorance – lights or objects sighted in the sky are unknown, and therefore they are alien spacecraft.

Intelligent design is almost entirely based upon this fallacy. The core argument for intelligent design is that there are biological structures that have not been fully explained by evolutionary theory, therefore a powerful intelligent designer must have created them.


Confusing absence of evidence with evidence of absence
This fallacy cuts both ways. In other words, one might assume that absence of evidence is a compelling argument against the reality of a claim or phenomenon. On the other hand, however, one might dismiss the absence of evidence as having no significance – as not being evidence of absence.

In reality, the absence of evidence can only be properly considered in the context of how likely it is that evidence should exist. You must therefore consider how thoroughly evidence has been looked for, and if the tools and techniques employed are capable of finding evidence. For example, if you dredge the bottom of a sea with a net that has one inch holes in order to survey the life living in that sea, you will likely not come up with any creatures smaller than one inch in size. It would not be logical to then conclude that there are no fish smaller than one inch living in that sea.

This fallacy is central to the Bigfoot debate. Believers in Bigfoot claim that the absence of hard evidence of Bigfoot is not evidence that Bigfoot does not exist. Skeptics, however, argue that a population of large mammals living in North America should produce some evidence, such as the occasional corpse.


Argument from Personal Incredulity
I cannot explain, imagine, or understand this, therefore it cannot be true. However, reality is not limited by our ability to comprehend it, or by our comfort with it. Creationists are fond of arguing, for example, that evolution is false because they cannot imagine the complexity of life resulting from blind natural processes, but that does not mean life did not evolve.

Subtype: Appeal to Ridicule
This form of the argument from personal incredulity argues that a claim is false because it seems ridiculous. Of course, some claims are ridiculous and it is legitimate to arrive at such a conclusion after careful examination of the logic and evidence. However, it is a fallacy to dismiss a claim a-priori simply by labeling it ridiculous or absurd. Many ideas that initially seemed far-fetched, such as the notion that invisible tiny organisms cause disease, or that space and time are relative and not constant, turned out eventually to be proven scientifically valid.


Confusing currently unexplained with unexplainable
Because we do not currently have an adequate explanation for a phenomenon does not mean that it is forever unexplainable, or that it therefore defies the laws of nature or requires a paranormal explanation. An example of this is the "God of the Gaps" strategy of creationists that whatever we cannot currently explain is unexplainable and was therefore an act of god. The history of science has taught us, however, that even the most intransigent of natural mysteries may eventually yield to scientific investigation.


False Dichotomy
This fallacy consists of arbitrarily reducing a set of many possibilities to only two. For example, evolution is not possible, therefore we must have been created (assumes these are the only two possibilities). Actually, this fallacy can apply to any premature reduction in the possible set of explanations for a phenomenon – not necessarily down to only two possibilities. UFO proponents, for example, will often analyze a sighting by saying the object was not a plane, not a balloon, and not celestial object, therefore it was a flying saucer. They are limiting the set of possibilities to a few easily dismissed choices, and the desired choice, while ignoring the many other possibilities.

This fallacy can also be used to oversimplify a continuum of variation to two black and white choices. For example, science and pseudoscience are not two discrete entities, but rather the methods and claims of all those who attempt to explain reality fall along a continuum from one extreme to the other.


False Continuum
This is the idea that because there is no definitive demarcation line between two extremes, that the distinction between the extremes is not real or meaningful: There is a fuzzy line between cults and religion, therefore they are really the same thing. This fallacy is especially important to understand in the context of medicine; most human traits vary according to a Bell curve of variation. “Unhealthy” is often defined as being too far out to one extreme or the other. The false continuum logical fallacy is sometimes used to argue that these extremes are merely part of a continuum of variation, and therefore have no meaning or significance. However, this is like saying that “short” and “tall” have no meaning because human height is a continuum of variation. Blood pressure is a good example. We can meaningfully define high blood pressure because it correlates with increased risk of certain disease, such as heart attacks, even though high blood pressure is at the upper end of a continuum of variation.

In part this logical fallacy represents discomfort with the concept of a fuzzy line of demarcation between two extremes. But such fuzzy lines are more the rule than the exception in this complex world.


Inconsistency
Applying criteria or rules to one belief, claim, argument, or position but not to others. For example, some consumer advocates argue that we need stronger regulation of prescription drugs to ensure their safety and effectiveness, but at the same time argue that medicinal herbs (which are pharmacological agents – drugs) should be sold with no regulation for either safety or effectiveness.


The Moving Goalpost
A method of denial - arbitrarily moving the criteria for "proof" or acceptance out of range of whatever evidence currently exists. Creationists are most famous for this fallacy. In Darwin’s time they argued that in order for evolution to be true there would need to be a method of inheritance that allowed for new variation to persist and propagate, rather than merely become diluted in the larger population. Mendel’s discovery of “genes” fit the bill. They then argued that if evolution were true there should be many transitional fossils, but no number of transitional fossil discoveries seems to be enough to satisfy them. Intelligent Designers now argue that evolution cannot explain the appearance of biochemical pathways and microscopic structures – but as these pathways and structures are rapidly being explained they simply continue to move the goalpost further and further back.


Reductio ad absurdum
In formal logic, the reductio ad absurdum is a legitimate argument. It follows the form that if the premises are assumed to be true it necessarily leads to an absurd (false) conclusion and therefore one or more premises must be false. The term is now often used to refer to the abuse of this style of argument, by stretching the logic in order to force an absurd conclusion. For example a UFO enthusiast once argued that if I am skeptical about the existence of alien visitors, I must also be skeptical of the existence of the Great Wall of China, since I have not personally seen either. This is a false reductio ad absurdum because he is ignoring evidence other than personal eyewitness evidence, and also logical inference. In short, being skeptical of UFO's does not require rejecting the existence of the Great Wall.


Slippery Slope
This logical fallacy is the argument that a position is not consistent or tenable because accepting the position means that the extreme of the position must also be accepted. But moderate positions do not necessarily lead down the slippery slope to the extreme. There may be legitimate reasons to accept intermediate positions.

For example, those, like Thomas Szasz, who believe that mental illness does not exist have argued that if we classify depression as an illness that will lead to governments classifying political protest as a mental illness, because they are both mental states. This slippery slope argument ignores the important differences between a debilitating mood disorder and a political opinion.


False Analogy
This is any argument that is based upon an analogy that is false because of important differences between the situations being compared.


Straw Man
This is arguing against a position which you create specifically to be easy to argue against, rather than the position actually held by those who oppose your point of view. Therefore this consists of misrepresenting an opposing view in such a way that it is vulnerable to attack, because, for example, it is based upon flimsy evidence or invalid logic.

UFO proponents (and many other true believers) have often dismissed skeptics by saying that they reject anything they cannot see with their own eyes. This is a straw man because scientists accept logical inference as a legitimate method. I have never seen a black hole but I accept their reality because the evidence strongly infers their existence.


Tautology
A tautology is an argument that utilizes circular reasoning, which means that the conclusion is also its own premise. The structure of such arguments is A=B therefore A=B, although the premise and conclusion might be formulated differently so it is not immediately apparent as such. For example, saying that therapeutic touch works because it manipulates the life force is a tautology because the definition of therapeutic touch is the alleged manipulation (without touching) of the life force.


Conclusion

The more you practice examining arguments for their premises and logical fallacies, the better you will get. I think you will find it is the best method for resolving differences in factual conclusions. It is also helpful in that it can take away the personal emotional content of an argument; if the focus is on facts and logic, the arguments tend to be less personal.

Finally, the most important arguments to examine in this way are your own.

A Flawed Equation

If your fat the first thing someone who is thin might tell you is, "Oh, it's easy to lose weight, because scientists have determined that weight is just, food in minus exercise out." While there is more truth to this comment then most fad diet programs it's actually much more complicated.

It's not, Fat = F - E;

F = Kcal of Food
E = Kcal of Exercise

It's more like, Change in Fat = F*Pf + C - (Mr + A)*Pe - M

And I am not a doctor, so you could probably make the equation even more accurate! However, I am very confident that this equation covers the basic ideas of human metabolism and weight loss. Let's look at the different factors, and then in later posts I will post valuable information on how to control each variable.

F = Kcal of Food, you think you consumed
Pf = Perception of your food intake that differs from reality
C = Kcal from Muscle consumption
Mr = Calories you think you used to restore anaerobic muscle energy and repair/grow muscle (ATP)
A = Calories you think you burned during Aerobic exercise
Pe = Perception of your Exercise that differs from reality
M = Metabolic calories burned for general maintenance of your body.

Where have I been?

I have been working on my physical fitness and losing weight. I have also been looking for full time work either in New Hampshire or here. Soon I will share my 6 months of work and research on health and fitness, specializing on weight loss.
