Psychologists are supposed to make the most ethical decision they can in any circumstance. select the best answer from the choices provided t f

I think that this is true, but also that this is true not only for psychologists, but for people in general - we should be taking the most ethical decision in any circumstance. However, this might be problematic, as people disagree about what is ethical - still, considering ethics in decision-taking is a good way of maximizing people's benefit and making sure we are not hurting anyone

So the statement is true. 

I would say that however, psychologists have even more responsibility to make ethical   decisions because they are specifically trained to do so.

The answer is *True* , They must make the most ethical decisions possible under any circumstances.
