Yes, actually, if someone has direct scientific evidence contrary to the claim (I doubt such evidence exists for your first example as to the best of my knowledge the relationship between beans and gastrointestinal changes is well understood).

Your eyes could hurt for a variety of reasons - brightness, too long screen time, being dry for external reasons, etc. Most humans are poor at identifying the cause of one-off events: you may think it's because you turned on a blue-light filter, but it actually could be because you used your phone for an hour less.

That's why we have science to actually isolate variables and prove (or at least gather strong evidence for) things about the world, and why doctors don't (or at least shouldn't) make health-related recommendations based on vibes.

> if someone has direct scientific evidence contrary to the claim

Except they don't. This is evidence about one potential mechanism. Not evidence saying there are no other potential mechanisms.

This is actually a very common mistake in popular science writing, to confuse the two.

It's pretty clear, even on monitor, night and day difference at a push of a button. I'm not arguing if this helps you sleep better but it is pretty arrogant of you to tell me I can't figure out from my own experience if something is comfortable or not.

It’s about the equivalent of someone claiming my saying I find woollen clothing directly touching my skin to be irritating / itchy requires double blind randomised controlled studies to determine whether this is true at the population level.

There are eight billion of us, we can’t all be different, there must be at least some categories we can’t be sorted in to, maybe those who find woollen clothing itchy and those who don’t, and those who find blue-light reduction more comfortable and those who don’t.

One of my pet theories is that this hyper fixation on The Ultimate Truth via The Scientific Method is what happens when a society mints PhDs at an absurd rate. We went up with a lot of people who learn more and more about less and less, and a set of people who idolise those people and their output.

Nobody really cares if it's comfortable or not for you, the debate at hand is whether it's measurably more comfortable for the population at large.

		That’s how it should be but the poster is literally calling the individual experiences of others “superstition” based on the population at large.

If your eyes routinely hurt when doing something, and then they stop routinely hurting after you make a change, that's pretty good reason to believe that there's a causal effect there.

Sometimes the causality is clear enough that you don't need sophisticated science to figure it out. Did you know that the only randomized controlled trial on the effectiveness of parachutes at preventing injury and death when jumping out of an airplane found that there is no effect? Given that, do you believe there really is no effect?
