From Philippe LePerre:

Re: Study: red enhances men’s attraction to women (Oct. 29): Has this experiment been made with persons from USA only or from all kinds of cultural / ethnical background ? US scientists tend to consider that White US-ians (Bolivians guatemala, mexico, tierra del fuego is also america) represent (and own?) the whole mankind. In that they tend to extrapolate what they find on a few people from new York and Albany to “humans”.
