An example of alpha bias is Freud and the differences between the oedipus and electra complex.
The Electra complex doesn't involve castration anxiety unlike the oedipus and therefore the girls aren't forced to identify an internalise with their mum as boys do with their dad.
This leads to a weaker superego which freud states increases the likelihood of criminality.
So essentially, Freud states women are more likely to become criminals which is not true and is therefore damaging.
