The 85% Rule for Learning - Scott H Young
If you're always successful, you won't know what to improve. If you always fail, you won't know what works.
We learn the quickest when the success rate is 85 percent.
Imagine you're studying for a test by doing practice problems.
The 85% rule suggests that learning is best when we practice tasks that we can succeed at roughly four-fifths of the time. If you're getting one out of every five problems wrong, you may need extra help. If you're getting nearly all the problems right, you need to move to more difficult ones.
Theories of optimal learning show that we learn best when it is not too easy and not too hard.
We are a group, not a team - something I never want to say about my colleagues.
