I found this one extremely thin. There's a title that says we're "hard-wired" for rc. Then makes claim that our aversion to corners is a result of socialisation (i.e. not hard-wired). The case is simply ridiculous. Do parents not mind when we play with jelly-fish, but get upset when we eat sandwiches? Do schools round the corners on textbooks lest children suffer physical or emotional damage from those nasty sharp corners? There's no substance here, just vague claims and circular citations.
