Failing makes some people smarter
One particular barrier is perception.
The process of understanding events is called sensemaking. People experience something, and they mull it over, and arrive at an explanation. The interpretation might be wrong. Because we never see the whole picture, our interpretations will most likely be incomplete at best. But right or wrong, the interpretation becomes the meaning for that person. And that incorrect interpretation is a barrier to learning.
In the sensemaking process, a major cause of misunderstanding is fundamental attribution error. In particular, people often confuse internal and external causes.
For example, when one of my students receives a high grade on a test, it is due to a combination of hard work, dedication, and superior intelligence. When a student fails a test, the failure is caused by my evil plot to ruin young lives. (By the way, I arbitrarily choose which lives to destroy).
Don’t try to fail. But when you do, don’t lament the economy, the weather, or other people’s stupid decisions. Consider instead what YOU could have done differently.
