This is example of what I call "the tipping paradox", and I'm almost sure that this phenomenon has its own proper scientific name.

When asked, people prefer €15 burger no tip, but when actually making a choice, they prefer €10 burger with €5 tip. Similarly, companies state "bug-free code" as a goal or requirement, but then they prioritize other goals over code correctness. My workplace is in the process of completely removing code reviews. And actually, I don't disagree with the decision - my career is short, but I have never seen reviews fulfill any purpose other than to share the blame in case of an incident.
