There was a hearing about torture (I think it was in the US Senate). An interrogator who was said to be highly effective was answering questions. A senator asked something like:
"Torture has been used since mankind has been around, it must be pretty effective."
His response was something like:
"No it is just EASIER to hit someone, not more effective."
Based on studies like the one described in the article, there are much better tools than torture if you're actually trying to extract useful information.
It’s a political cartoon that shows that shows how torture is used. I didn’t cite it as a research paper. The studies I referred to were described in the main article
"Torture has been used since mankind has been around, it must be pretty effective."
His response was something like:
"No it is just EASIER to hit someone, not more effective."
