Cognitive Bias

There are almost 200 named biases; they help us with decision making, social interactions, and memory errors.

Another way to consider biases is to think of which problem they are trying to solve.

With too much information, we use biases to filter quickly, by looking for repetition, or confirmation.  When there is not enough meaning, we use stories or patterns to find the signal.  Needing to act fast makes us simplify with overconfidence or status preservation.  If there’s something to remember, stereotypes and editing show up.

Every cognitive bias we have, is used to save the brain’s energy or time.
