Citation needed. If I was going to go out on a limb, I'd say a large part of the reason women aren't drawn to tech at a young age is because it requires you sit alone in front of a computer talking to it for long stretches of time instead of interacting with other people, but I have as much evidence as you do that it has to do with a lack of role models. (I got into programming well before I knew any famous programmers.)

You are correct that that is another large contributing factor. There are a few other ones too, such as the lack of real-world application of what they learn, stereotypes, a terrible culture towards women in CS, and a few other massive problems. They all work against the on-going efforts.

As for the Role Model aspect in particular... It's actually difficult to provide citations, because it's so commonly accepted in the community. I attended Grace Hopper '13 last year, and it's just recognized as a given. When I go through research papers from the past 5-10 years, they start off by just recognizing that its a known problem and then move onto subproblems or their new solution. Unfortunately, I don't really have the time to go mining the work that led to this problem being recognized. Still, I can recommend a book, "Unlocking the Clubhouse" http://mitpress.mit.edu/books/unlocking-clubhouse which should cover this!

Surely both of these are factors. I would suggest:

1. That at an early age, programming role models in particular aren't as important as STEM role models in general. It's certainly anecdotal, but I moved towards programming as a practical job that somewhat satisfied my broader interest in science and engineering.

2. It might be beneficial to girls and boys alike if technology was taught more socially. Certainly tinkering and reading alone is important, but maker clubs and the like are an extraordinary way to get young people involved. As a bonus, they help with teamwork which is another big issue for (many) tech companies.

I'm gonna go out on a limb here and say you should stop going out on a limb, as you're clearly very poorly informed when it comes to these matters. But here's a citation for you: http://economixcomix.com/2014/04/20/neil-degrasse-tyson-on-g...

I clicked on that expecting some kind of study to refute my random theory, which I'd find interesting, but it's a high level vague theory from Neil DeGrasse Tyson about the evidence of bias in society. (Something we should give approximately the same weight as any theory based on anecdotes and personal experience.)

He'd be the last person to tell you his observations and this anecdote should be seriously used as a citation to lend yourself weight in an argument about the source of gender bias in tech.
