Ethic on psychology

we were made to write a 2-3 page essay on the ethics of 3 different studies. the studies were The Milgram experiment The Little Albert experiment and The Blue eyes vs. Brown Eyes experiment all of these studies had something unethical about them but the two that i believe were the worst are the Milgram and little Albert, they were cruel and unethical harming another human is wrong and should never be done for the benefit of science or entertainment. the blue vs. Brown was a lesson on how not discriminate against anyone and that to me is a great lesson to teach a child.
