This tends to be more of the norm for the ones at 'good' institutions, which is aligned with the common knowledge / heavily replicated studies that 'top performers (best students, etc) are the most likely to cheat. There can still be good academic works (and the alternative in industry has even worse incentives, such as intentionally hiding the ability to replicate) but unfortunately the structure as of now rewards bad behavior.
