Rather than just recording what you think will happen, PredictionNote allows you to record just how sure you are that it will happen. If you're properly calibrated, you'll be able to see that about 60% of the things you're 60% sure will happen, do happen, and 90% of the things you're 90% sure will happen, do happen.
We should be careful to get out of an experience only the wisdom that is in it.Mark Twain
Doubt is not a pleasant condition, but certainty is absurd.Voltaire
The most practical thing in the world is a good theory.Hermann von Helmholtz
