It definitely happens, and increasing awareness of it is a good thing, since I imagine most men don’t want to be known as crushing bores. The fact that women can be patronising doesn’t mean it isn’t gendered behaviour; there doesn’t have to be an exact correlation for the relationship to exist.
That said, it wasn’t an issue I noticed when I worked in a field which was 60% women. This has made the phenomenon very apparent when I moved to a field which was 80-90% men. It’s not the men who work in my field who give me problems, by and large. They can better assess my competence, and also are aware of the gaps in theirs. It’s men who have no experience who appear to think that because I work in a traditionally male area, they must know more about it than me - despite all evidence to the contrary - and feel the need to corner me in the pub to try to assert this expertise.
The last time it happened, I ended up breaking it down for them as follows:
I have studied this for x years. I have worked in this field. I have these qualifications. I have done this research. I have these publications. I have lectured on these modules, I have read, at my last count, 700 papers on this matter, I provide peer review to other experts on this topic.
You have: not studied this area; not worked in this field; no qualifications in this area; done no research in this area; no publications in this area and not attended, let alone given, any lectures on this topic.
But you have: read two articles. Both of which I have also read. One is a two pager in New Scientist, a decent summary, but written by someone with no first hand knowledge. The other is an opinion piece, written by someone who is funded by a major stakeholder and who freely admits they are not independent. I know this because I have talked to them at conferences on a number of occasions.
A pair of testicles.
Well, they must be bloody massive testicles, mate, given you appear to believe they outweigh all the other points.
And still they keep on: No, no, no. You haven’t considered…
I have considered it. I considered it five years ago, for ten minutes, then concluded it was a stupid idea, and furthermore I can think of at least a dozen papers off the top of my head which prove why it’s a stupid idea, which I can send to you, if you like.
No, no, no, you haven’t considered…
Yes, I have. Because unlike you, I am an expert in my field, and considering this stuff is, in fact, what I am paid to do.
No, no, no, on and on, ad infinitum.
What reward they get out of this behaviour I have no idea. It is literally laughable; people are laughing at them. I can only conclude that for some people negative attention is better than no attention.
