The idea that waterboarding and other abuses may have been effective in getting information from detainees is repellant to many, including me. It’s contrary to the meme many have embraced: that torture doesn’t work because people being abused to the breaking point will say anything to get the brutality to stop — anything they think their accusers want to hear. But this position is at odds with some behavioral science, I’ve learned. The architects of enhanced interrogation are doctors who built on a still-classified, research-based model that suggests how abuse can indeed work.

I’ve examined the science, studied the available paper trail and interviewed key actors, including several who helped develop the enhanced interrogation program and who haven’t spoken publicly before. This inquiry has made it possible to piece together the model that undergirds enhanced interrogation.
