A general limitation of the human mind is its imperfect ability to reconstruct past states of knowledge, or beliefs that have changed. Once you adopt a new view of the world (or any part of it), you immediately lose much of your ability to recall what you used to believe before your mind changed.

You're surprised by something, but you don't really know what surprised you; you recognize someone, but you don't really know what cues cause you to recognize that person.

An investment said to have an 80% chance of success sounds far more attractive than one with a 20% chance of failure. The mind can't easily recognize that they are the same.

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

When people think of the outcomes of their decisions, they think much more short term than that. They think in terms of gains and losses.

The brains of humans contain a mechanism that is designed to give priority to bad news.

The confidence people have in their beliefs is not a measure of the quality of evidence but of the coherence of the story the mind has managed to construct.
