It certainly seems like a plausible argument that better detectors leads to a smaller necessary sample.

Why do you assume the problem is that human beings select CEOs and not that how we select the selectors is broken. That is, maybe the problem is who we decide are "well qualified capitalists"

But there is a limit to how small a sample can be regardless of the quality of the detectors because what you are looking for has to be in the sample. If the sample is merely a pinprick of blood, as Theranos (at least originally) claimed was enough, it very well might not be.

[HWR_14]

Sure. As a non-expert, I assume most drops of my blood have enough stuff in them to detect. How much can vitamin levels or viral loads change between drops of blood? Certainly they seem to draw more than strictly needed.

[jhbadger]

It depends on what you are looking for. Yes, for say small molecules like vitamins a pinprick (less than a microliter) could theoretically be enough. But if you are looking for things like early infection or cancer, the signals you want may not actually be in such a small sample at all.

I don't think that's a problem, as I don't think the decision is "well-qualified" as in competent, but rather "won't end up on the dole if this investment falls through". Henry Kissinger isn't signing up for food stamps/EBT because his Theranos investment went belly-up. The problem is that many thought, "well, if Henry Kissinger is in...", without asking about Mr. Kissinger's qualifications to evaluate medical claims.

[HWR_14]

Oh, "qualified investor" qualifications. In that case, why does anyone think that they would be particularly skilled at hiring CEOs?

[perl4ever]

Compared to who?

[HWR_14]

I'm not sure why they would be more skilled than any random people off the street, or a coin flip, etc. There's no reason to think they produce a result better than whatever control group you can think of compared to any other subset of people.

[perl4ever]

The modal random "qualified investor" is probably a dentist, not Kissinger.

[HWR_14]

And your point is you think Dentists (or Kissinger) should be presumed to be good at choosing a CEO?
