Most people are highly optimistic most of the time.

If individuals are rational, there is no need to protect them against their own choices.

Optimism is normal, but some fortunate people are more optimistic than the rest of us. If you are genetically endowed with an optimistic bias, you hardly need to be told that you are a lucky person - you already feel fortunate.

This is the essence of intuitive heuristics: when faced with a difficult question, we often answer an easier one instead, usually without noticing the substitution.

We have no reason to expect the quality of intuition to improve with the importance of the problem. Perhaps the contrary: high-stake problems are likely to involve powerful emotions and strong impulses to action.

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

People should be conscious of the large contribution made by anything that gets people together easily in the reduction of loneliness and emotional well-being.
