September 23, 2016

Habits are our immediate automatic responses--good and bad--to situations when we don't take the time to manufacture a purposeful decision. Decision science gives us the psychological framework within which to understand how habits form and are activated, and how best to change them when we want to.

3. The Role of Heuristics in Decisions

September 23, 2016

Heuristics are the decision shortcuts that people use every day. While too imprecise to lead to optimal decisions, they are powerful tools that allow you to make appropriate decisions fairly easily. However, if you don't understand the limitations of heuristics, they can easily lead you astray from the truth into stereotyping and assumptions.
