The only thing I'm saying is that measuring once maximises the luck component. Sure, measure other things by proxy as well. But to borrow your phrase, understanding and taking into account the variability of real life behaviours, sampling noise and environment biases shows "not only intelligence, but also for suitability to certain jobs."

No, it doesn't. Repeating it ad infinitum does that.

But therefore it's a good thing grades aren't just pass or fail, but have a range, from 1 to 10, or to 20 or whatever. Too bad there's so much external pressure on the system.

Take a moment to think about it. Why does the confidence interval go smaller with more samples? What does it say about the impact of luck in repeated tests?

In tests, reseats allow you to take the maximum, not the average. The maximum goes asymptotically up.
