Great question. People have different personalities and different responses to their mistakes. Mistakes can be small or large, happen once in a while or constantly. Depending upon the circumstances and the psychological effect, a person could be looking out for mistakes in which to have a serendipitous discovery, or on the other hand, every mistake could remind them of a horrible accident or belittling of their spirit.
Those who have been hurt over and over again from each little mistake will have the emotional fear response. Those who have been praised for discovering something new will look forward to future mistakes.
Don't spill the beans!
