Clearly, the decision-making that we rely on in society is fallible. It's highly fallible, and we should know that.
Friends are sometimes a big help when they share your feelings. In the context of decisions, the friends who will serve you best are those who understand your feelings but are not overly impressed by them.
My interest in well-being evolved from my interest in decision making - from raising the question of whether people know what they will want in the future and whether the things that people want for themselves will make them happy.
All of us would be better investors if we just made fewer decisions.
When you are under time pressure for a decision, you need to follow intuition.
Policy makers, like most people, normally feel that they already know all the psychology and all the sociology they are likely to need for their decisions. I don't think they are right, but that's the way it is.
We associate leadership with decisiveness. That perception of leadership pushes people to make decisions fairly quickly, lest they be seen as dithering and indecisive.
One of the major biases in risky decision making is optimism. Optimism is a source of high-risk thinking.
I think one of the major results of the psychology of decision making is that people's attitudes and feelings about losses and gains are really not symmetric. So we really feel more pain when we lose $10,000 than we feel pleasure when we get $10,000.
In strategic decisions, I'd be really concerned about overconfidence.
The effort invested in 'getting it right' should be commensurate with the importance of the decision.
Spend some effort in figuring out why each decision did or did not pan out. Doing that systematically is key: really try to question the way you make decisions, and improve it.
