Breaking news:
Psychologist who still refers to adult women as 'girls' is nonetheless taken seriously enough to have theory published! That's not even plausible evo psych. It's just the sort of crackpot theory one might make up over dinner. Probably during the cigar course...
George old pal, why do you think the girls love shopping so much?
Why, Dan, I don't know. Could it be a convenient excuse to temporarily avoid our harrumphing sexism?
No no! It's evolution. Me man. Me hunt. It's genius! It manages to separate the men from the girls while simultaneously making me look like a neanderthal! A suburban neanderthal, at that.
And just to make sure I personally was as amused as possible, the article throws in some shenanigans about linear directionality vs. spatial awareness. Which doesn't even make logical sense in this argument.
Those silly evo psych boys.
