Most successful people know you can’t rely on luck and achieve results that are both predictable and reliable. It may be possible to have an occasional victory, but most successful endeavors require more than luck and superstition.

But what role does luck play?

A 2010 study published in the journal Psychological Science found that superstitions are typically seen as inconsequential creations of irrational minds. Nevertheless, many people do things like search for four-leaf clovers, hang horseshoes or avoid walking under ladders.

Present research reveals performance benefits of superstitions are realized from underlying psychological mechanisms.

Experiments show it is not a magical power that improves results, but good old-fashioned beliefs and behavior that combine to create changes in perceived self-efficacy, confidence, and increased task persistence.

So, the next time you are looking for a little extra help, remember to believe in yourself and keep going!
