Certified financial planner Jill Schlesinger has seen smart people make some pretty spectacular money mistakes.

One client who repeatedly refused to buy disability insurance later developed multiple sclerosis. A doctor she knew put off writing a will and left behind a six-figure tax bill. A technology company engineer balked at her suggestion to sell some of his stock options, only to watch their value and his retirement plans evaporate when the market plunged.

Schlesinger, a CBS News business analyst and author of “The Dumb Things Smart People Do With Their Money, ” admits to financial missteps as well, including waiting for “just the right moment” to invest and missing a big jump in the stock market.

“We’re emotional animals, not just rational ones,” Schlesinger says. “So even otherwise intelligent people are stymied by their emotions – usually fear and greed – and their cognitive biases.”

In fact, a whole field of economics is devoted to exploring how we make financial decisions – including the bad ones. Behavioral economics tries to pinpoint where our brains and emotions lead us wrong, as well as what we can do about it.
