Lever points in a complex adaptive system are according to John H. Holland points at which a small effort can produce a desired, directed effect. They are similar to Gell-Mann's frozen accidents.
John H. Holland writes about them (see here)
- "Almost every complex adaptive system that we know of has lever points. These are great things if you can find them. A lever point allows you to make big, directed changes for a relatively small effort. A vaccine is a good example of a lever point. An immune system is terribly complex. But we do know that for some diseases, we can make a small injection and train the immune system to resist a disease for the rest of its existence — much longer than the life span of any blood cell in your body."
