The first time I failed a project, I felt like an imposter. I spent weeks going over every detail, trying to figure out where I went wrong.
Recently, machine learning and neuroscience researchers have discovered something fascinating about the ideal rate of error for accelerated learning: the Rule of 15.87%.
The Golden Zone of Learning
If you get it right 100% of the time, the task is too easy. You are not learning; you are just doing what you already know. Your brain goes on autopilot, and neuroplasticity (the ability to form new connections) decreases.
If you miss 50% of the time, the task is too difficult. Frustration sets in, dopamine falls and withdrawal is likely.
The ideal point? Make a mistake about 15-16% of the time. It is at this point that the challenge is high enough to keep you engaged, but not so high that it becomes impossible.
What this changes in practice
This means that in your career or company, if everything is going perfectly well, you're probably not innovating enough. You need to put yourself in situations where the chance of failure exists. That's where exponential growth happens.
