Defect
Argue the other side at full strength, never as parody; stop only when you have made its best case.
Argue against yourself.
Seen in Fyodor Dostoevsky, "The Grand Inquisitor", The Brothers Karamazov, 1880
Try it on your work
Take the material, tool, or method you have been deliberately avoiding and use it, fully and in good faith, for one session. Write one line the avoidance had been protecting.
Argue, aloud or in writing, the position in your project you most disagree with, as its best advocate, not its parody, for ten full minutes. Keep the one point you couldn't defeat.
For one cycle, adopt wholesale the approach of the rival: the competing method, the other school, the way the other team does it. Import the single piece that worked; you now hold it without the allegiance.
How it has been used
Abandon your own position and argue the other side as its best advocate: the lawyer switching chairs, the chess player turning the board. The move forbids parody: you must make the opposing case at full strength, and the discomfort is the evidence you're doing it.
