I'm afraid our experience is very different. I find the programming world to be full of people who will interpret guidelines like DRY with almost religious dogmatism, particularly if anyone Internet famous can be cited as the source.
Having been a mentor to many younger and less experienced programmers when they started working professionally, I have been the guy who had to clear up their absolute, literal belief in these sayings. Some people will quickly understand and accept that the world isn't as black and white as perhaps their CS course/favourite blogger/previous boss said or that they have taken rules of thumb too literally. Some never really do understand that, and their code reflects their lack of understanding and often looks like it was written to comply with every saying under the sun as its primary goal.
