Nobody would say, 'I'm voting for this guy because he's got the stronger chin,' but that, in fact, is partly what happens.

People who are cognitively busy are also more likely to make selfish choices, use sexist language, and make superficial judgments in social situations.

There are some conditions where you have to trust your intuition.

We can't live in a state of perpetual doubt, so we make up the best story possible and we live as if the story were true.

We are very influenced by completely automatic things that we have no control over, and we don't know we're doing it.

To know whether you can trust a particular intuitive judgment, there are two questions you should ask: Is the environment in which the judgment is made sufficiently regular to enable predictions from the available evidence? The answer is yes for diagnosticians, no for stock pickers. Do the professionals have an adequate opportunity to learn the cues and the regularities? The answer here depends on the professionals' experience and on the quality and speed with which they discover their mistakes.

It is the consistency of the information that matters for a good story, not its completeness. Indeed, you will often find that knowing little makes it easier to fit everything you know into a coherent pattern.
