Although I'm not sure I am on board with the synthesis - it wants to play it both ways: that women are unfairly given smaller pockets but are also incapable of prioritizing it for themselves.
Out of curiosity I showed this page to my wife (who loves to complain about pockets). When seeing the pants with the bigger pockets, she complained about the fit or aesthetics of those brands, so I think the traits may be linked. She also admitted she doesn't much care for things in the front pockets anyway.
Still, amazing presentation and data set.
