Jean Maria Arrigo's inbox is filling up with apologies. For a decade, colleagues of the 71-year-old psychologist ignored, derided and in some cases attacked Arrigo for sounding alarms that the American Psychological Association was implicated in US torture. But now ... a devastating report has exposed deep APA complicity with brutal CIA and US military interrogations - and a smear campaign against Arrigo herself. David Hoffman, a former federal prosecutor, confirmed what she has crusaded against for a decade: the APA's institutional involvement with torture led to a concerted effort to quash dissent, lie to the public, and silence people like her. In 2005, Arrigo ... was a member of an internal panel, known as the Task Force on Psychological Ethics and National Security (Pens), that greenlit psychologist participation in national-security interrogations. The taskforce was intentionally weighted in favor of the US department of defense, through stacking it with representatives from the military and CIA. It rejected efforts ... to include references to the Geneva Convention and specific interrogation techniques that psychologists could not be involved in. Arrigo took her concerns public. In response, [Gerald] Koocher ... who served as APA president in 2006, [launched] "a highly personal attack." Arrigo said she was untroubled by Koocher's "idiotic" broadside. What was more troubling to her, she said, were the well-meaning members of APA who did not challenge the attacks.
