"It is certain that the study of human psychology, if it were undertaken exclusively in prisons, would also lead to misrepresentation and absurd generalizations"

This quote by Jacques Yves Cousteau recommends that if the study of human psychology was just carried out in prisons, it would cause incorrect conclusions. This is since the prison population is not representative of the general population, and so any findings would not apply to the broader population. Cousteau is cautioning against the risks of drawing conclusions from a restricted sample size, as it can lead to false presumptions and generalizations. He is highlighting the value of performing research study in a range of settings in order to get a more accurate understanding of human psychology. By doing so, researchers can avoid the risk of misstatement and inaccurate generalizations.
