In a computer training class recently, I learned the following statistics on retention rates from my teacher.
When you read, you retain 10% of what you read.
See and hear: 50%
Discuss with others: 70%
Experience it personally: 80%
What we teach someone else: 95%
This explains why we only confirm what we know when we have to teach what we know to others. The path to become an expert requires one to teach what one practises.
What is the retention rate when we collaborate with others, such as planning a concert or a fundraising event or working on a CD recording together? When performers work with composers, both learn from each other and the process. The commitment that both put into the resulting composition takes it further than a one way process. Would the retention rate be higher?
