Fallacy of the predetermined outcome

A phrase frequently used by Yankees announcer Michael Kay to refer to the flawed logic behind thinking that event x is set in stone and would have happened regardless of all events leading up to it.
Michael kay:” You don’t want to fall victim to the fallacy of the predetermined outcome, but you have to wonder how things are different if the umpire called that pitch a strike.”

no true douchebag fallacy

It is a logical fallacy that can be identified as when someone says something so absolutely ridiculous and stupid you just want to slap them with your dick because they seriously believe the shit they're saying.

Me: It really doesn't work that way.

My Roommate: You're fucking stupid, how the fuck did you even get into college?

fallacy

In logic, a fallacy is an incorrect conclusion. This may result in one of two ways.
1. If the structure of the argument is not correct at all, it is called a 'formal' fallacy. One, or both, of the first two propositions would be written incorrectly in relation to the other.
2. If the structure is correct in the first two propositions, but the conclusion is not put together properly, it is called an 'informal' fallacy.

The usual example of an argument that has no fallacy is:
Socrates is a man.
All men are mortal.
Therefore: Socrates is mortal.

Each sentence is a proposition. No propositions in an argument must be factually true to in order to create an argument with no fallacy; they must only follow the rules of logic. It is when the structure, the rules of logic, does not conform to the 256 various forms of a syllogism, it will contain a 'formal' fallacy. When only the conclusion does not follow the rules, it is an 'informal' fallacy.

Search for 'moods and figures of logic' for a full account of structure in logic.
1. It is a formal fallacy to say
Socrates is a man.
Dogs are mortal.
Therefore: Socrates is a dog. The second premise must contain either 'Socrates' or 'man' ('men), and in the right order. This is what is meant by the 'structure' of the argument.

2. It is an informal fallacy to say:
Socrates is mortal.
Dogs are mortal.
Therefore: Dogs are Socrates. The first two propositions are written correctly by the rules of logic, but the conclusion is written incorrectly.
