The way our brains work can cost us a lot of money. But some of our mental quirks can be turned to our advantage.

Cognitive biases are the faulty ways of thinking that can persuade us to run up debt, save too little and make stupid investment decisions. The bandwagon effect, for example, entices us to buy the hot stock everyone’s talking about, rather than the mutual fund that makes more sense for our long-term goals. Or we sign up for a too-large mortgage because of optimism bias (“I’ll figure out a way to make the payments, somehow!”).

We can try to be more rational, but sometimes it makes sense to exploit our faulty wiring instead. In my latest for the Associated Press, three money biases that you could put to work for yourself.
