For women, it's not the stigma of IT being boring. It's the reality of it being home to a lot of underdeveloped men who continue to see women as objects instead of people. Even at a more progressive company I worked for with a very LGBT friendly culture, IT still had people in it that made women uncomfortable. Why? First comment out of one of the IT employees mouths when he heard a woman was being hired for the group was "Is she hot?".Even when we ask the recruiter to specifically send us women for very technical positions in networking, telephony and software development the numbers that we see are minuscule. In my case, when I graduated there was this stigma of IT being boring and difficult so I don't have an answer on how we can improve the odds of more women in IT.
It's those types of comments, those types of views, and those types of actions that result in women avoiding IT like it's disgusting. Because unfortunately, it is.
Recruiters have to also be aware of some of the differences to be able to find candidates too. Many continue to use tactics that have been shown to only result in male applicants rising to the top.
None of this means anyone is a bad person, it's means that we have more work to do to help people become aware of their own unconscious biases. The victorian era view of gender still has a strong grip on many societies, including here in the US.
