Three errors that I see a lot
Insofar as all men are rational, all men can reason. Insofar as all men have hands, they can paint. Difference is, not all have the training and tools to do either. First, similarity means the same. This is the error of an accidental [mistaken] cause. Secondly, what applies to a group applies to an individual. This is the error of collective versus genus (or universal). Thirdly, it is either A or B. This is the error that says simply different things are contradictories. The POC only applies to those [A and ~A], not two different things. I hear these three all the time. They obfuscate matters and reasoned discourse impossible. [now if I could only avoid them]
