Reminds me of why torture as a means of information gathering is ridiculous.

I will absolutely tell you what I think you want to hear when you start stabbing me, whether its the truth or I ever knew it at all.

But I also hate you for torturing me, so If I do happen to know the thing then I also know enough about the thing to alter the answer to something false but plausible for a moment of relief while you act on it, because we all know if you're torturing me, you have no intention of letting me out alive.

This is why the lets be pals/wine and dine approach is more effective.
