If you're looking for a job or trying to get ahead in this economy, there's some age-old wisdom that would seem to apply: play up your accomplishments. Seems obvious, but maybe that's in fact not your best plan of attack.

A recent paper from researchers at Stanford and Harvard sets out to show that potential for success is considerably more powerful than the things you've actually achieved.

So why would we ever gamble on potential over proven experience?

"You can think about it a little bit like peoples' love of scratch tickets," says author Michael Norton, an associate professor at Harvard Business School, "where you have a dollar in your pocket, and the dollar in your pocket is great. But if you could get that scratch ticket, you could have $5 million."
