Yup, just because it's researched doesn't mean it was good research (from a general standpoint). Since this is Lego's 6th attempt at reaching this market, I'll assume they've tried to take extra care. It's even possible that the work was done in collaboration with university academics (with peer-reviewed papers as a result). If it doesn't work, I'm sure they'll figure out what went wrong and make a 7th attempt in due course.

The questions you pose are excellent research topics in their own right (if reworded slightly). I really hope there are people out there looking into them. I remember reading some autism-related research that described how even newborn babies exhibited male/female differences (very contentious at the time and I don't know how the field developed).
