#32There’s no evidence parachutes work.

#33What point is this article trying to make?
They state the point at the end, and it's serious point: if you were inclined to use "science" to argue against a certain intervention that some group believes in, you could do a randomized trial of that intervention, but manipulate the conditions so that the intervention is unlikely to help. The study would look right and sound right to some people. It would use all the best practices. And yet it would be a bullshit…
> [The study] would use all the best practices
You've go some major contradiction here, since when is such manipulation "the best practice"?

#34I came to leave a snarky joke comment about "in mice?", and then I remembered that mice don't actually need parachutes because their terminal velocity is roughly the same as a human using a parachute [1]. If someone actually ran the study with mice, they'd find that parachutes aren't necessary! 1: https://johnmjennings.com/can-a-mouse-survive-a-fall-from-a-...
> You can drop a mouse down a thousand-yard mine shaft; and, on arriving at the bottom, it gets a slight shock and walks away, provided that the ground is fairly soft. A rat is killed, a man is broken, a horse splashes.
"A horse splashes". That's some mental imagery right there.

(Less snarkily, we're all making resource allocation decisions constantly and on the margin those are life or death decisions).
IMHO, on the margins you're allowed to use common sense. Also: your grandma / your grandpa, your resources applies.

#37Does this result simply mean you just can’t reject the null hypothesis (parachute makes no difference)? Rather than a proof of it?
