That post made me write this post, but I'm not sure that I'm referring to the same thing. Basically I mean something like "people whose beliefs or actions are so unreasonable, even on things that they should have thought long and hard about, that they seem to belong to a different species from myself." Like Robin Hanson in this tweet or Elizer Yudkowsky when he thought he would singlehandedly solve all the philosophical problems associated with building a Friendly AI (looks like I can't avoid giving examples after all). I'm pretty sure these two belong in the top 0.1 percentile of all humans as far as being reasonable, hence the title.

You could use things like being able to outperform the market, being consistently ahead of the Overton window, finding a reception for your less objectively verifiable ideas among (a small group of) other high-performing individuals. This doesn't guarantee that you're not still a lizardman among the 99.9%+ lizardmen, just in a high-performing contrarian cluster (hence my rule #1), but at least rules out being a crazy person living in a normal world (unless you're just hallucinating all of the evidence, but there's no point worrying about that).

Sorry for being unclear. I meant producers of those commodities, except for uranium for which I also have some exposure to the commodity itself.

If you spend any time following stock touts on twitter / stock picking forums etc you will see these people quickly.

The people I follow generally don't advertise their track record? For the hedge fund manager I mentioned, I had to certify that I'm an accredited investor and sign up for his fund letters to get his past returns. For the ones that do, e.g., paid services on SeekingAlpha that advertise past returns, it has not been my experience that they "then fail to do so out of sample" (at least the ones that passed my filter of being worth subscribing to).

I generally find posts like this are net-negative EV.

Personally, I wish I had seen a post like this 10 years ago. My guess is that there's at least 2 or 3 people on LW who could become good traders if they tried. Even if 10 times that many people try and don't succeed, that seems overall a win from my perspective, as the social/cultural/signaling and monetary gains from the winners more than offset the losses. In part I want LW to become a bigger cultural force, and clear success stories that can't be dismissed as "luck" seem very helpful for that.

Especially if those are after tax returns!

Pre-tax.

I have never achieved anything close to those levels of returns, but would sorely love to do so.

Maybe try some of my tips, if you haven't already? :)

Without even checking, I can think of a bunch of assets which 7x'ed since Jan 2020. (BTC/general crypto, TSLA, GME/AMC etc).

I figured that's the first thing someone would think of upon hearing "7x" which is why I mentioned "This was done using a variety of strategies across a large number of individual names" in the OP. Just to further clarify, I have some exposure to crypto but I'm not counting it for this post, I bought some TSLA puts (forgot whether I made a profit overall), and didn't touch AMC. I had a 0.1% exposure to some GME calls which went to 1% of my portfolio and that's the only involvement there.

Personally, I have seen enough people claiming to outperform, but then fail to do so out of sample.

Can you please give some examples of such people? I wonder if there are any updates or lessons there for me.

Either way, I think it's very hard to convince me with just ~1.5 years of evidence that you have edge. I think if you showed me ~1k trades with some sensible risk parameters at all times, then I could be convinced.

I don't think I've done that many trades (depending on how you define a trade, e.g., presumably accumulating a position across different days doesn't count as separate trades). Maybe in the low hundreds? But why would you need ~1k trades to verify that I was not doing particularly high variance strategies? I guess this is mostly academic though, as it would take a lot of labor to parse my trade logs and understand the underlying market mechanics to figure out what I was doing and how much risk I was taking (e.g., some pair/arbitrage trades were spread across several brokers depending on where I could find borrow). I don't supposed you'd actually want to do this? (I also have some privacy concerns on my end, but maybe could be persuaded if the "value added" in doing this seems really high.)

Or if in another year and a half you have $300mm because you've managed to 7x your small HF AUM, I will be convinced

I'm definitely not expecting such high returns going forward. ("600% return" was meant to be Bayesian evidence to update on, not used to directly set expectations. I thought that went without saying around here...) Obviously there was a significant amount of luck involved, for example as I mentioned the market was particularly inefficient last year. One of the hedge fund managers I follow had returns similar to mine this year and last year, but not in the years before that. I'd guess 20-50% above market returns is a realistic expectation if market conditions stay similar to today's, and I hope I can still outperform if market conditions go more "out of sample" but I currently have no basis to say by how much.

Also, I'm already starting to feel diminishing returns (is there a more technical term for this in the investing world?) kick in at my AUM level, as I now have to spend multiple days accumulating some positions to the sizes that I want (and they sometimes take off before I finish), or ignore some particularly illiquid instruments that I would have traded in the past.

1 in 5 isn't especially strong evidence.

I agree this isn't a very strong argument. I think theoretically we can probably get a much tighter probability bound than 20% by looking directly at the variance of my strategy, and concluding that given that variance, the probability of getting 600% return by chance (assuming expected return = market return) is <p for some smaller p. But in practice I'm not sure how to compute this variance. Intuitively I can point to the fact that my portfolios did not have very high leverage/beta, nor did I put everything into a single or very few highly volatile stocks or sectors, which are probably the two most common high variance strategies people use. (Part of the reason for me writing this post is that while LW does have a number of people who achieved very high investment returns, they all AFAIK did it by using one of these two methods, which makes it hard to cite them as exemplifying the power of rationality.)

Assuming the above is still not very convincing, I wonder what kind of evidence would be...

I currently have ~100 positions spread across: uranium, copper, lithium, oil, fertilizer, shipping, Nvidia Google Microsoft Baidu (hedge against short AI timeline), a basket of SPAC/deSPAC commons&warrants (which I bought after the SPAC sector became severely depressed), individual "value stocks" and "special situations" in various other sectors. Most of these were entered within the last few months, and my portfolio looked pretty different before that, but I can't really talk about what I was doing before without risking de-anonymizing myself.

The efficient markets model says that any strategy during this period had expected return of 50%.

Wait, I think this is wrong. It actually says that any beta 1 strategy had the same expected return as the market as a whole. If my portfolio had a beta of 2, for example, either by using leverage or by buying only high beta stocks, then my expected return would be double that of the market.

I wish I could say that I kept my portfolio's beta at or below 1 at all times, which would make the reasoning easier, but I did sometimes trade derivatives that arguably had high beta. It would be pretty cumbersome to calculate the exact overall beta, but I'd guess that the average over time probably wasn't more than 1.5, so you could perhaps redo your reasoning using that.

I recommend looking at commentators as a source of data, but doing your best to not believe anything that could reasonably be classified as an opinion rather than a fact. That includes opinions about what topics deserve attention.

This must be the biggest disagreement between us. I think I couldn't possibly have gotten the return that I did if I had followed this advice, especially the latter part about what deserves attention. Can you say more about why you think this?

ETA: Aside from the fact that it seems to have worked in practice, my theory is that it's easier to detect good ideas than to generate them, especially when you read/hear arguments/comments from multiple perspectives, which is often possible (e.g., multiple SeekingAlpha articles plus their comments, and analyst reports about the same stock). (The same core premise makes AI Safety via Debate plausible.)

See also this Twitter thread for some additional insights into this story. Given the politically sensitive nature of the topic, it may not be a great idea to discuss it much further on this platform, as that could further antagonize various camps interested in AI, among other potential negative consequences.

Hacker News discussion about why Margaret Mitchell was fired. Or see this NYT story:

Google confirmed that her employment had been terminated. “After conducting a review of this manager’s conduct, we confirmed that there were multiple violations of our code of conduct,” read a statement from the company.

The statement went on to claim that Dr. Mitchell had violated the company’s security policies by lifting confidential documents and private employee data from the Google network. The company said previously that Dr. Mitchell had tried to remove such files, the news site Axios reported last month.

One relatively easy and low-cost idea: buy some physical Bitcoin and/or gold, hide them somewhere, and hedge them with short positions (in Bitcoin futures and/or gold ETFs) if you don't want to be too exposed to their price movements. It's probably a good idea to have some exposure to them anyway as a hedge against inflation. And in case it's not clear, physical Bitcoin means on a hardware wallet that you can easily hide and carry with you when you need to move.

Ah, I think you're right. It seems like they want an "ethnic studies" version of everything and students have to take at least one ethnic studies course per year. I'm not a huge fan of that and it seems like it is taking some well-deserved criticism.

FYI, there is virtually no criticism within the city / school district itself, because (1) it's too progressive / left-leaning and (2) anyone who does offer criticism gets labeled as "racist" or "white supremacist", even if the critic isn't white. (Look up "internalized oppression" if you're not already familiar.)

Looking at this presentation through the lens of the original post, it seems like what the Ethnic Studies Board is trying to do is create safe spaces and reduce perceived harms against minorities (hence, I think, why they want to make sure there's an "ethnic studies" version of every core class: so that the people they feel will best benefit from this curriculum can use it for their entire high school education).

That's part of it, but it's also about turning students (and not just minorities) into social justice activists. See this quote from page 31 of the presentation:

Critical pedagogy aims to engage students in an exploration of their world in order to gain a political and critical consciousness. It is based on the belief that historical events are the result of a series of contradictions and their solutions.

Humanizing pedagogy is a component of critical pedagogy that encourages learners to recognize oppression doesn’t just happen and they are agents of change.

Educators who employ critical pedagogy accept that the practice of teaching can never be apolitical when systems of oppression exist. Educators see education as a tool of resistance and liberation.

Critical pedagogy transforms the learning environment from one of passivity to one of action and change. Students don’t learn for the sake of learning, but learn to understand the how and why of social systems that oppress certain groups and privilege others.

Combine this with other forms of political correctness (e.g., it's taboo to even talk about "culture" as a factor in educational disparities; any differences in educational outcomes must be the result of racism/oppression) and it's hard not to be concerned about the outcome of this educational philosophy and to see certain worrying historical parallels.

BTW, I don't know if it's a good idea to get into a big object-level discussion about this here. Initially I just wanted to offer some clear-cut evidence to correct your belief that "bring SJ into all the sub­ject at school" is unlikely. Hopefully that's settled at this point?

The curriculum isn't mandatory

I believe this is a mis-reporting, or talking about part of the curriculum. See pages 27 and 28 of this presentation:

We believe that all courses should incorporate Ethnic Studies curriculum, however at a minimum, students should participate in 4-5 ethnic studies classes in high school, i.e., a minimum of 1 ethnic studies course per year. [...]

A graduation requirement is a way to ensure that Ethnic Studies classes reach all students.

This sounds unlikely, uncharitable, and frankly more than a little conspiratorial. I'm not even sure if this is something most social justice advocates would even want.

It's already happening IRL. See this Reason article:

The district has proposed a new social justice-infused curriculum that would focus on "power and oppression" and "history of resistance and liberation" within the field of mathematics. [...]

If adopted, its ideas will be included in existing math classes as part of the district's broader effort to infuse ethnic studies into all subjects across the K-12 spectrum.

Comment by at_the_zoo on Utility functions and quantum mechanics · 2012-09-01T01:41:51.262Z · LW · GW

Can you explain why "the only measure available is indeed the ordinary amplitude-squared measure"?

Also, I'm confused about this:

Continuity: If you prefer |A> to |B> and |B> to |C>, there's some quantum-mechanical measure (note that this is a change from "probability") X such that you're indifferent between (1-X)|A> + X|C> and |B>.

According to the Wikipedia entry you linked to, a probability measure is a real-valued function, but X here is apparently just a number? What's the significance of your parenthetical note here?

This seems relevant:

Five: US tax law prohibits public charities from getting too much support from big donors.

Under US tax law, a 501(c)(3) public charity must maintain a certain percentage of "public support". As with most tax rules, this one is complicated. If, over a four-year period, any one individual donates more than 2% of the organization's total support, anything over 2% does not count as "public support". If a single donor supported a charity, its public support percentage would be only 2%. If two donors supported a charity, its public support percentage would be at most 4%. Public charities must maintain a public support percentage of at least 10% and preferably 33.3%. Small donations - donations of less than 2% of our total support over a four-year period - count entirely as public support. Small donations permit us to accept more donations from our major supporters without sending our percentage of public support into the critical zone. Currently, the Singularity Institute is running short on public support - so please don't think that small donations don't matter!
