FISNM Rule #2 – Logic must apply

Posted on September 4, 2012. Filed under: Exercise |

Dear sweet logic. One of my favorite principles in regards to science. Shame it gets misused so often in the fitness field.

 

There are many forms of logic, which range far beyond the scope of this blog. Essentially logic is how we determine what is a good idea or bad idea.

 

Note I said idea, not fact, for it I logic that allows us to strip away concepts until we ultimately find the truth or fact of the matter.

 

Among the important aspects of logic we have Consistency, Validity, Completeness, and Soundness. Without going too far into definitions you can get the idea of these properties.

 

An idea has to be consistent in its outcome, and able to be validated clearly. It must be a complete and sound idea unto itself, and therefore applicable in our real world.

 

An argument is said to be “valid” if its conclusion follows clearly without any form of divert from its origins; it is “sound” if it is valid and if all the premises are true. The rule of logic thus governs the validity of a conclusion based on evidence and reasoning.

 

Although philosophers have a rainbow of forms of valid arguments, it is not necessary to Aristotle to apply this rule consistently and correctly.

 

An invalid argument can be recognized by the simple method of a counter example. If you can think of a single imaginable realistic instance whereby the conclusion would not necessarily follow from the original statement, even if the statement were true, then the argument is invalid.

Consider the following example:

  • Jane has 6 pack abs
  • Jane does Zumba
  • All people who do Zumba have 6 pack abs

 

This argument is invalid because a single Zumba dancer without 6 pack abs would provide an effective counterexample. If an argument is invalid, then it is, by definition, unsound. Not all valid arguments are sound, however.

Consider this example:

  • Everyone who does 90XRC workouts burns 1000 calories
  • Jane is doing 90XRC
  • Jane is burning 1000 calories

 

That argument is unsound, even though it is valid, because the first premise is false: Everyone who does 90XRC is not going to burn 1000 calories.

 

Logic is beautiful in its simplicity, and unfortunately it’s that simplicity that creates a problem to determine whether a valid argument is sound is frequently problematic; knowing whether a given.

 

In order to determine if a statement of logic is true or false often demands additional knowledge about the claim that may require empirical investigation. If the argument passes these two initial steps, and is both valid and sound chances are you can accept it comfortably.

 

The rule of logic is frequently violated by internet scientists and trainers who think they are doctors, guru, and who know what else. Celeb trainers are commonly known for making statements that are logically invalid and factually inaccurate. This comes as no surprise as the very basis of their existence is invalid.

 

A celeb trainer claims their methods work because they train certain actor and actresses. Yet the celebs often claimed are people are already known for having good bodies… well by Hollywood standards good bodies any way.

 

This gives them confidence to then go forward and make direct false statements. For example, one of the more infamous statements by celeb trainer is that a woman should never lift more than 5 lbs.

 

Not only is the argument invalid (an endless number of scientific study how this to be false), but the premise that all women want to look like a stick figure celeb is beyond off base. This trainer has also made the statement that running makes you bulky.

 

It can be hard to filter, and do the back ground work needed to find the logic. But it’s important when it comes to your health.
