When you are doing workshops, particularly teaching something that people are "sitting through" rather than engaging with, you see very similar ratios on end of segment assessment multiple choice questions. I mentioned elsewhere that this is the same kind of ratio you see on cookie dialogs (in either direction).

Think basic security (password management, email phishing), H&S etc. I've ran a few of these and as soon as people hear they don't have to get it right a good portion of people just click through (to get to what matters). Nearly 10 years ago I had to make one of my security for engineers tests fail-able with penalty because the front-end team were treating it like it didn't matter - immediately their results effectively matched the backend team, who viewed it as more important.

I talked to an actor a few days ago, who told me he files his self-assessment on the principle "If I don't immediately know the answer, just say no and move on". I talked to a small company director about a year ago whose risk assessments were "copy+paste a previous job and change the last one".

Anyone who has analysed a help desk will know that its common for a good 30+% of tickets to be benign 'didn't reason' tickets.

I think the take-away is that many people bother to reason about their own lives, not some third parties' bullshit questions.
