[Happy Monkey]

Torture provides false confessions. In the cases where they provide true confessions, the torture continues until the torturer is satisfied, which is unlikely to coincide exactly with the amount of actual intelligence the subject has. Therefore, it is likely that even true coerced confessions will be mixed with stuff that the subject thinks the torturer wants to hear.

There's a reason that torture is usually associated with situations where the veracity of the confession is of minimal importance.
