It is important to distinguish between meritocracy, and the ideology of meritocracy. The article fails to make this distinction when it says in int conclusion
> Despite the moral assurance and personal flattery that meritocracy offers to the successful, it ought to be abandoned both as a belief about how the world works and as a general social ideal.
when the evidence presented attacks the ideology of it, but not meritocracy itself. The former refers to
* Putting people with merit into positions of responsibility, or
* Rewarding people who have merit.
The ideology includes 2nd-order and nth-order effects like:
* believing that people who are rewarded have merit (including that one had merited the success/failure one has)
* believing that proxies for measuring merit are accurate
* believing that our present implementation of meritocratic principles is both widespread and fair
In my opinion, ideally, we should retain the first principle of trying to give responsibility to people of merit, but abolish the ideological notions that meritocracy is successfully being practiced to good moral effect. And because merit and capability itself is so greatly affected by chance, and so too its measurement, we should strive to reduce how much we reward those seemingly with merit vs. those without.
