"There is no bigger cliché in business psychology than the idea that high self-confidence is key to career success," Tomas Chamorro-Premuzic, professor of Business Psychology at University College London, tells Jen Hubley Luckwaldt at Payscale.com "It is time to debunk this myth. In fact, low self-confidence is more likely to make you successful."
And the reason why is because those with lower self-confidence are able to digest negative feedback from bosses more easily. They're most able to take this criticism and turn it into something positive.
But this theory doesn't include people with extremely low self confidence, but with "just-low-enough confidence," which Chamorro-Premuzic says leads people to create realistic goals, but they're not so low that they constantly suffer from anxiety or doubt everything they tackle.
