Slow thinking has the feeling of something you do. It's deliberate.

If people can construct a simple and coherent story, they will feel confident regardless of how well grounded it is in reality.

The amount of success it takes for leaders to become overconfident isn't terribly large.

Facts that challenge basic assumptions-and thereby threaten people's livelihood and self-esteem-are simply not absorbed. The mind does not digest them.

In a rising market, enough of your bad ideas will pay off so that you'll never learn that you should have fewer ideas.

There's a tendency to look at investments in isolation. Investors focus on the risk of individual securities.

To better avoid errors, you should talk to people who disagree with you and you should talk to people who are not in the same emotional situation you are.
