The article is worse than confused. It's a marketing piece written in a way that sounds vaguely science-y but with only a tenuous basis in real research.
> I'm willing to entertain the idea that LED flicker is actually problematic, but I wish essays like this would be honest about the degree of confidence we have given the current state of the evidence.
I (and it seems others too) are very interested in this topic. I would appreciate if you could write an aritcle with "less confusion" so I can save it in my tumblog for future reference.
Yep, it's obvious that a lot of people are interested because junk articles like this usually get penalized harder. That interest is what this piece is preying on. Unfortunately it's easier to write a piece that tells people what they want to hear and spreads FUD than it is to write a piece that corrects the misinformation.
Much more rewarding too, because "we really don't know very much about this yet" is hard to expand to a full click-worthy essay and less likely to move product.
