Socially sensitive research

this is biologically determinist, according to this theory, men in particular are aggressive bcs of adaptations that increase reproductive success of ancestors. this implies it is inevitable that men are aggressive and therefore not their fault

this may cause feminist concerns → men are excused for crimes (e.g. abuse, assault) and continues ‘boys will be boys’ mentality
