We make millions upon millions of decisions during our lifetime. Some big, some small. We’re born with a lot of innate abilities but decision making certainly isn’t one of them. Smart people make dumb decisions all the time and are vulnerable to thinking errors. Since our lives are essentially the result of all our choices, it makes sense to devote a good deal of time to thinking about decisions and how we can improve our ability to make better decisions.

Thinking About Decisions

Each decision represents a bet about an uncertain future. We make that bet based on our beliefs — on what we believe to be true about the world around us.

A bad result doesn’t necessarily mean a bad decision.

You can make the smartest, most well thought out decision and still have it completely fuck up. Was that then a bad decision?

No, a good decision is always a function of a good decision making process. It’s made on the basis of the information you have at the time. Sure you can wait a long time until you have all the information you need but by then, that would render the decision itself irrelevant too.

Think about decisions in terms of probabilities.
