Over the decades psychologists have discovered all kinds of biases in how we think.
Some tell us why the incompetent don’t know they’re incompetent, others why it’s difficult to estimate our future emotions and some why we feel more transparent to others than we really appear.
Many of these biases result from our minds using little short-cuts to help us navigate through a complicated world. Unfortunately the result can be that we reach irrational decisions.
Understanding how these biases operate may help you make better decisions in all sorts of situations, both at home and work. More than that, though, it will help you understand your own mind.
