The source is common sense, experience, and original thought. I don't copy every thought I have from an NYT article or whatever you're looking for. Minimax is emphatically not even remotely close to EV maximization, especially for high-dimensional optimization spaces with sharp risk/return curves as I described.

You're making empirical claims about the world as if they are obvious, so I expected you would have a shred of evidence backing what you were saying, but I guess I forgot we were on HN. Unsure why you would think I was expecting a NYT article (except as some weird cultural signaling point?), I was thinking more along the lines of a welfare economics or econometrics journal article.

  The two likely possibilities are that you have enough background in utility/optimization/portfolio/whatever theory to reverse-engineer my thought process, or you need a lot of additional background that I can't feasibly provide in a single HN comment. Either way, linking to some random economics journal article is unlikely to help. I might as well link to a bunch of textbook pages defining all the words I used. As I said, this is an original thought of mine, so if an article reiterating what I said exists, I am in not much better a position to find it than anyone else on here. Apologies if this seems harsh, but people's habit of asking for a source on every original or propositional claim on this website really bugs me. Sometimes people are sharing new observations!

    I have a background in economics and optimization and have not seen a claim as strong as the one you are making. Again, given that you are making an empirical claim about the world as we find it, I would expect you would be basing that on something you could point to - but I guess not. Not going to keep responding, I've said all I wanted to.

      Look above you in the thread[1] for a very simple demonstration of how "EV maximization and so-called "maximin" overlap a considerable amount of the time" can be false. I am not really clear on what background you could have such a background but be unable to generate this fact, Wikipedia seems to suggest it strongly when it points out that "In non-zero-sum games, this is not generally the same as minimizing the opponent's maximum gain, nor the same as the Nash equilibrium strategy" [2]. This isn't a personal attack, but you really could have got this one solved by looking at either the thread or Wikipedia, but chose to assign someone else research homework instead. If you're curious, check! It's really fun and you learn a lot.
