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.
