Logical Fallacies

The fallacy that I think I have heard of or seen the most would be the hasty conclusions one. Hasty conclusions is when you have one piece of evidence and then you assume something. For example, All girls that wear Abercrombie and Fitch shop only at that store. So if I saw a girl that was wearing Abercrombie and Fitch I would automatically assume that she only shops at that one store. I think that this one is a very common fallacy. Its probably the most common in verbal arguements, your trying to prove your point so any type of information you get you will assume something about it.
