This might put a big beurocratic burden on a/b testing _anything_ by definition.

Do i exploit human psychology by changing my sign up button text to free trial? Now we might need a committee to decide.

It's odd to me that the United States Government would consider outlawing infinite scroll, but has not considered outlawing motorcycles, free rock climbing, cave diving, etc.

Truthfully I'm always more surprised that large American cities don't do more to encourage motorcycling.

Seems pretty irresponsible considering they're death machines. I had one in my blind spot on the highway the other day, and it was virtually invisible. I always manually check beside me too, I never trust my side mirrors. Literally couldn't see her. Luckily, nothing happened, but I don't understand what people are expected to do when they can't see you.

A quick web search indicates that in 2016 motorcyclists were 28 times more likely (per mile driven) to die in an accident than those driving a car.

Are the dangers as hidden?

Is hiddenness really the pertinent criterion?

Yes.

I like that bold, unambiguous answer. But really, after you've encountered one or two infinite scrolls, how much of a surprise is it to encounter the next one?

It's not about the surprise factor, it's that there's a good chance you fail to process that you're being manipulated.
