I don’t know how such a survey could control for projection, though. I remember reading Susan Fowler’s “blog post that was heard around the world” that ended up taking down Uber’s CEO (and nearly Uber itself) and being surprised how little of it had anything to do with being a woman - most of the frustrations she expressed were things that I’ve been frustrated by, too. It seems to me that she just experienced what every developer experienced (other than the thing about the T-shirts) and attributed all of it to her being a women, assuming that the grass must be greener on the other side.

Hmmm, I wouldn't think that it would be a fact finding mission, but a plain old survey of opinion.
