critical thinking

The goal of critical thinking is to arrive at the most reasonable beliefs and take the most reasonable actions. We have evolved, however, not to seek the truth, but to survive and reproduce. Critical thinking is an unnatural act. By nature, we're driven to confirm and defend our current beliefs, even to the point of irrationality. We are prone to reject evidence that conflicts with our beliefs and to attack those who offer such evidence.

The items below are listed in alphabetical order. For someone new to the subject, I suggest the following order of reading:

1) several essays I've written on the difficulty of changing minds: Belief Armor, Evaluating Personal Experience, Why Do People Believe in the Palpably Untrue?, Defending Falsehoods, and Why Woo-woo Wins.

2) the following entries: confirmation bias, cognitive dissonance, communal reinforcement, motivated reasoning, backfire effect, memory, and perception deception.
