> Oh, there's one important detail here. The drop in the study was about 2 feet total, because the biplane and helicopter were parked.

I don't think that's making the argument you think it is.

> It's like "A study found that parachutes were no more effective than empty backpacks at protecting jumpers from aircraft."

Are you under the impression that we don't bother to empirically prove things that seem obvious, like the safety benefits of parachutes? You don't think parachute manufacturers test their designs and quantify their performance?

I think my employer should buy me a laptop and possibly a monitor or two to help my productivity because I subjectively feel they'd be helpful, and I have the market power to insist on tools that I subjectively feel are helpful. If my CEO announced that monitors are super important and everyone will be tracked on monitor space usage going forwards, I would still want to see evidence that this is going to accomplish something.
