Psychologists have studied suspects and have been looking for mental quirks. They have also suggested the lines of interrogation and questioning and have helped in deciding when an argument is too intense, or when to push harder in getting what you want. Psychologists in the military and C.I.A. interrogation have marked a central spot.

But now has appeared a new issue. Is the psychologists’ involvement in military interrogation a violation of its code of ethics? The American Psychological Association in Boston say such works are unethical while civilian and military say that giving away the psychologists would make the interrogations more likely to harm the detainees.

Still, this association doesn’t have enough power or authority to restrict the members’ ability to practice their job. Amnesty International plans a protest on Saturday and the election of the association’s president is strongly connected as a referendum to this problem.

Lawyers for a prisoner at the U.S. Navy in Guantanamo Bay, Cuba, said that the psychologist is a critical player and they pointed out an abusive treatment.

William J. Strickland, the one who represents the Society of Military Psychology said that “The vast majority of military psychologists know the ethics code and know exactly what they can and cannot do.”

Until now, not much is known about these military units and the number of psychologists who take part in it.

Jean Maria Arrigo, a psychologist studied the relationship between psychologists and military intelligence stated that “American psychology really grew up with the military. “It was barely considered a science before the collaboration began, and the entanglement goes very deep.”
