Logic is fundamental to most of humanity’s knowledge, but there are common fallacies in logic and reasoning, errors of judgement which happen due to:

While engaging in an argument or debate, red herrings are certain statements or points that seem relevant to the core issue but are merely distractions. Red herrings themselves can be logical fallacies due to the factor of correlation and causation.

If two incidents or things happen at around the same time does not mean that one thing is the result of the other. Often many things occur at the same time yet are completely unrelated.

The Slippery Slope fallacy is a mistaken belief that one relatively mild unaddressed problem or allowance will automatically lead to other negative consequences.

“You are either with us or against us!” Oversimplification of options, due to selectively providing a limited set of options and not encompassing other potential options creates a false dichotomy.

This logical fallacy occurs when one’s own assumptions are used to establish their argument and prove it to be true.

A common argument tactic online, Ad hominem is when instead of giving a response to the argument, the person is attacked in a personal way, leading to the focus being the kind of person he or she is, rather than the actual content of the (now forgotten) argument.

When a logical argument is not going anywhere, one party can sometimes try to win brownie points by appealing to an outside authority, the majority, or even towards feelings of pity.
