That may be part of it but I've also observed it among fellow programmers.

You give your opinion about something and your coworker has a smug, arrogant knee-jerk reaction based on some cargo-cult belief without actually thinking about the details of the problem. Then you need to walk them through why what you said is not what they meant step-by-step, and while it may be wrong it is still a valid opinion. If you succeed, they completely change and become cooperative, and you can have an actually useful discussion. But you have to be super patient, like when taming an irritated feral cat that wants to scratch you. If you're good, the cat becomes cuddly and cute.

This works but I'm extremely tired of having to perform this dance with 60% of the new coders I meet.
