In the beginning of "The Great Gatsby", Nick brags that he is not at all judgmental and is able to understand where people are coming from. This leads him to trusting people and thinking the best of them. By the end of the novel, after he has had so many uncomfortable and unfortunate experiences tangled up in the lives of Gatsby, Daisy, Tom, Jordan, etc, Nick finds himself to be very judgmental of their lifestyle and personalities, especially the Buchanans. He removes himself from their company and becomes more reserved, less trusting.
A logical fallacy is a flaw in logical reasoning. There are numerous flaws in judgment. One example is the "ad hominem" fallacy, where instead of arguing a point, the person attacks the person's character. Ex. "We should ban cigarettes." "Why should I agree with you? You smell really bad!"
Another example is the "burden of proof" fallacy, where a person who makes a claim states that it is up to the other party to disprove them, rather than prove their own statement. This is fallacious because the inability to disprove something doesn't automatically mean that it is proven. Ex. "There is a teapot floating in between Mars and Earth at this very moment. Prove me wrong!" "I can't do that, because I can't go to space right now." "Therefore, I am right!"
This seems like it belongs more in the catagory of history but if the author is Thomas Jefferson, or any president from Jefferson until the Civil War than they are most likely for it
