so do placebos

I agree for sleep. I prefer them because they focus better for me.

Blue creates a halo around letters that is distracting with my declining vision.

Also, Blue fluorescent OLED are ~50% less efficient than R/G phosphorescent OLED so you can reduce screen power consumption of a full white page by almost 30% using such a filter. That in turn might be 30% of active device power consumption (for a total of almost 10% in battery life during active operation). Ignoring that they also tend to burn out more quickly, since tandem blue has become fairly mainstream.

Many more reasons for these "filters", if you don't mind the white balance shift and reduced color gamut.

So what? If I could take a sugar pill that guaranteed I feel comfier looking at my screen, nobody can tell me it "doesn't work". I'm not trying to optimise my life, I'm trying to have my eyes feel better.

Placebo and “manifesting”—the latter sounds mockable but pretty much the same thing, harmless if helpful so hey!

		If somebody is "manifesting" themselves a sleep aid, I think they'd just call it meditation and everybody would more or less accept that it probably works for that individual. Maybe you'd have a few people with severe autism who start arguing on online forums about the scientific evidence behind meditation, but that's just them being them.

		The placebo effect is a real, measurable mind-body response where belief & expectation can change your symptoms or how you feel. However, it does not directly alter external reality. Manifesting claims your thoughts or intentions can cause _outside events_ to happen, which has zero evidence to support it.

Not really. Most of the cultural notion about the remarkable effects of placebos came from flawed studies in the 1950s. As far as I can tell, the modern consensus is that there's no clinically significant placebo effect except for conditions that can only be measured by a subject self-reporting their own perception (like pain and fatigue).
