Ritically evaluate the role ethics has played in Psychology

I need the following areas to be discussed in my essay:

-History of psychology and development of ethics as a practice and aspect of regulation

Historical research that has been questioned ethically (intelligence research, scientific racism)

Problems with current traditional forms of ethics defined by the BPS,APA vs critical psychology approaches (too tick box, as long as ethics guidelines addressed nothing else matters)

Implications of psychologys engagement in controversial research and practise, ie military, social policy.
