Or perhaps the issue is assuming people know, or people understand the majority of the time.

There is a reason why the Scientific Method is, well, NOT natural for humans. And exceptionally difficult to not screw up, even for those highly trained and incentivized to do it correctly.

And why if you grabbed a random person off the street and asked them a detailed question, you're as likely to get a hallucinated bullshit response as 'I don't know', or a useful answer. Unless specifically trained to do otherwise, anyway.

Even then....
