Failing 15 per cent of the time is best recipe for success, study fiinds

Failing 15 per cent of the time is the best recipe for success, even more so than not failing at all, finds research. A study led by researchers at the University of Arizona proposed a mathematically devised optimum level of failure. Educational experts have long agreed that there is a'sweet spot' when it comes to learning, reasoning that people learn best when they are challenged to grasp something just outside the bounds of our existing knowledge. When a challenge is too simple, we don't learn anything new. Likewise, our knowledge doesn't improve when a challenge is so hard that we give up entirely.
