This epic page's introduction reads:
"Cognitive errors are those types of systematic mistakes which our brains make when presenting ideas and correlations to our conscious selves. They result from us applying evolutionarily developed rules of thumb to the complexities of life without taking due heed of the need for critical and cautious evaluation of our own thought processes. Human errors in general thinking can lead individuals, or whole communities, to come to explain types of events and experiences in fantastical ways. Before we can comprehensively guard against such cumulative errors, we need to learn the ways in which our brains can misguide us. They are divided into three areas: the internal errors of thinking, errors with our actual perceptions, and social errors that result from the way we communicate ideas and the effects of traditions and dogmas."
