How to use it
To grow a behaviour, add something good after it or take something bad away. To stop one, add a cost or take the good thing away. What follows the behaviour decides whether it comes back, so design the second after, not just the moment before.
How sure we are
S Evidence: strong. Large trials or many studies, pointing the same way.
E Evidence: built from practice. What works for coaches and practitioners. Labelled that way.
