I will reply to this comment since this is probably the most relevant. You're on point that there is a personal bias. Developers without degrees congregate together where they can, while developers with degrees congregate together to other places. There is a major self selection. Saw a lot of the first when I was doing contracting in the UK, saw a lot of the later as permanent in tech companies. If you're interviewing for google you're way more likely to have 2 stanford majors in the interview panel than 2 developers without format education.
