Took me a second to realise this was LW.

Your average narcissistic personality tests assume an average person as a test-taker, and so cannot tell whether one's overly inflated ego is justified or not.

Oof on the part of the author though:

Eliezer Yudkowsky: Nope.

Algernoq (the blogpost author): I assume this is a "Nope, because of secret author evidence that justifies a one-word rebuttal" or a "Nope, you're wrong in several ways but I have higher-value things to do than retype the sequences". (Also, it's an honor; I share your goal but take a different road.) [...]

Richard_Kennaway: What goal do you understand yourself to share with Eliezer, and what different road?

Algernoq: I don't deserve to be arrogant here, not having done anything yet. The goal: I had a sister once, and will do what I can to end death. The road: I'm working as an engineer (and, on reflection, failing to optimize) instead of working on existential risk-reduction. My vision is to build realistic (non-nanotech) self-replicating robots to brute-force the problem of inadequate science funding. I know enough mechanical engineering but am a few years away from knowing enough computer science to do this.
