An interesting form of torture, first perfected by Mr Isaac Newton a long time ago¹. If you have a prisoner that you want to confess to a crime (whether or not he/she is guilty), there are a number of techniques that can help. The most common is called Integration, and the practitioners of this most deadly technique refer to themselves as the Examining Board.

THE INTEGRATION

Part One

Force the prisoner to do a mathematical puzzle. This puzzle should look easy on first inspection, but whilst gaily solving it the prisoner should find that another problem, slightly harder than the first, needs to be solved in order to arrive at the answer. Solving this requires the answer to an even harder problem, and so on. Eventually, the will of the prisoner will crack, and you can proceed to part two.

Part Two

Using no more than half of a page of A4 paper, prove to the prisoner that the answer to the original, really easy looking problem is in fact 3. The mental paradox presented to the prisoner, the amalgamation of a problem that looks simple, becomes impossible but has an easy answer will drive him or her potty, and the prisoner will now succumb to your will.
