Let's call this the "Tilt principle."
When playing pinball, you can nudge the machine a little bit to keep the ball from going out of play. But if you nudge the machine too hard, you will "Tilt" the machine, ending that play.
That is incredibly easy to write. It is incredibly easy for a student to "learn" that statement to the point that they could write it on a test.
But to nudge a pinball machine at the right time takes skill and practice. Even the best pinball player in the world cannot always do it perfectly. The ace player might also take more risks with nudging when there is more at stake.
If you built a machine to teach pinball nudging, any traditional instructor would say, "that seems like a lot of work to teach what is essentially one simple statement." If you were becoming a pinball expert, however, you would absolutely need the deeper approach.
Now, obviously, no one cares about pinball.
But given that
- all Big Skills have a nudge component (how hard and when do you push your team, dealing with difficult people, getting the right amount of funding),
- the simple theories take a lot of practice to implement, and that
- the simplist rules when learned intuitively are as powerful as the most complex process,
...our entire concept of curricula and knowledge changes.
