Our field is burdened by complexity. Some people cannot function properly without illuding themself they can tame it. So they cling to rules, best practices, tools hoping that adopting them to the letter will protect them from the uncertainties of our job.

I've seen the opposite too, devs not only not writing any test, but not trying to run a single line of the code they wrote. Reason being I cannot test all the edge cases so I won't test it at all. QA will open a bug. And somehow getting praised by management for being faster than others to ship changes.
