This week every single newspaper in the world lapped up the story that scientists have cracked the pink problem. “At last, science discovers why blue is for boys but girls really do prefer pink” said the Times. And so on.
The study took 208 people in their twenties and asked them to choose their favourite colours between two options, repeatedly, and then graphed their overall preferences. It found overlapping curves, with a significant tendency for men to prefer blue, and female subjects showing a preference for redder, pinker tones. This, the authors speculated (to international excitement and approval) may be because men go out hunting, but women need to be good at interpreting flushed emotional faces, and identifying berries whilst out gathering.

Mainstream media science reporting is terrible.
