Logic is about understanding what follows from something else. If p, then q.
However, have we used the correct reasoning? Did we make the correct assumption or inference?
In logic parlance, from p to q. Logic takes us from the premise via inference, to a conclusion. However, often there are often logical fallacies, where a person is attacked, or correlation is not causation, or either-or thinking, distortion, overgeneralization, using a slippery slope, or a false analogy. Our own biases interrupt logical thinking. That is Confirmation Bias. Confirmation Bias is where we interpret and recall information that supports our own biases.
