It's more like, you will extract information, but only in hindsight can you ever know if it was worthwhile, accurate, a trap, etc. You will also kill some people, some people won't break easily, and some will babble anything and everything. You won't know which is which in the moment, and usually you're torturing for time-sensitive information.

What you get is what happened during WWII, when the resistances knew they just had to withstand torture for 24 hours, 48 at most. It's amazing what motivated people can do when they have a goal, and that goes for the tortured as well as the torturers.
