We leave it up to our scholars to decide where to apply, but in our experience they're generally aware that applying to Harvard, MIT, etc. is a good idea.

We're open to offering support for admissions counseling to some applicants who don't quite meet the bar for a tuition-and-fees scholarship. (All applicants who do meet the bar are offered counseling.)

We produced our own ranking of US universities based on factors like school selectivity, academic quality of the student body, and revealed preference data (such as cross-admit yields), plus some other "soft" factors. We sanity-checked this against existing school rankings and anecdotal impressions of people who have a lot of context on the US admissions process. We primarily used national rankings to determine the UK universities in our list, along with some anecdotal evidence about Imperial being the next-best choice (after Oxbridge) for a lot of STEM students.

(I also work at Open Phil and am involved in running this program.)
 

We just posted an announcement here that we’ll be running the program again this year.

Hmm, I’m skeptical of this model.  It seems like it would be increasingly difficult to achieve a constant 1.1x multiplier as you add more people.

For example, it would be much harder for Apple's 300th employee to increase their share price by 10% compared to their 5th employee.

I think overconfident and underconfident aren't crisp terms to describe this.  With binary outcomes, you can invert the prediction and it means the same thing (20% chance of X == 80% chance of not X).  So being below the calibration line in the 90% bucket and above the line in the 10% bucket are functionally the same thing.

I’m not affiliated with Canopy Retreats but I agree that’d be useful

If you expect to get nontrivial traffic, a URL redirect might be useful (you can do it at the domain level). A URL redirect adds some gravitas/decorum as well, which might be helpful. It looks like your registrar is Google so it should be pretty easy? https://www.whois.com/whois/earetreats.org

Out of curiosity, what's the logic with those graphs as the center and focus on the homepage? 

It does, but why is CEA capitalizing "effective altruism" now? 😕

Wow, I didn't even know that there is a new design. Looks really good. 

Timeline Swapping

Alice, a highly experienced ML researcher, thinks crunch time for AI will come in 20-30 years.  She spends quite a bit of her time community-building for AI safety, i.e. maximizing her impact if crunch time is in 20-30 years rather than if it is now.

Bob, a newer researcher with less skills, thinks we’re in crunch time now.  He might try to take a role at a current AI org that maximizes his current impact but isn’t spectacular for developing career capital.

It seems like if Alice and Bob could coordinate properly, Alice would operate under Bob’s timelines, Bob under Alice’s, and both would be better off.

 

Has anyone written more about this idea?

It appears that the tax situation in the U.S. is extremely disadvantageous for sports betting.  Total winnings (not net) are taxed as income and losses can only be deducted if you itemize.

For example, if you win $800 and then lose $1000, you are stuck paying taxes on $800, even though you have no net profit (if you don't itemize your deduction).  The tax rate for gambling winnings appears to be 24%, though I'm not sure if this is correct.  So for people who are trying the approach "bet $1000 on something very unlikely... if you lose, bet the...

Great point Kasey, and the tax rate for gambling winnings is actually just your marginal tax rate, but sportsbooks will withhold 24% for people who win 30x their stake on a given bet. This is a good resource for taxes in sports betting.

I agree with that analysis (and someone risk-neutral should bet the 2nd game on whatever game has the lowest vig).

Worth considering taxes, though.

The BetMGM one has the same $1000 promotion as Fanduel (actually worse, since you receive five free bets at 20% of your initial bet amount rather than a single one).  Can you update your post to reflect this?

Oh, good catch, I will edit that. What is the EV from those offers, then? It seems to still be nearly +$1000 and nearly risk-free with the following approach: bet $1000 on something very unlikely (EV of the payout will be $1000, but as something like a 1% chance of $100000). If you lose, bet the $1000 of site credit on something extremely likely, so you end up with $1000 cash. Then withdraw that. For BetMGM, repeat the same approach but do 5x very safe bets of $200 with the site credits. That still works for $1000 expected profit, right?

The Fanduel one isn't actually risk free (though still +EV).  The promotion is that if you lose your first bet up to $1000, they give you your wager amount back in site credit, which can't be directly withdrawn (and if you win you just get your bet winnings).

Betting the Fanduel promo alone carries risk, you're right. But you can de-risk it by taking the opposite side of the market and hedging your bet on a different, so that the worst case is 0 loss and best case is a free $1000 bet. You can then arbitrage that $1000 free bet again for a roughly $1000 gain (see this oddsjam link for potential markets to convert free bet into cash, basically markets with low to no vig). You can actually go further than that by optimally sizing your hedge bet such that your payout is the same regardless of which side of the bet wins. If you're interested I can copy my optimal hedge bet sizing excel calculator into sheets (and clean it up so that it's understandable to other people, lol) and share it with you.

Thank you for making this! I’ve been using this generously the past few days. One suggestion I’ll make is I think it would be nice if the episode descriptions were something like:

“Title, Date 

Beginning of post (50 words?) 

Link to post”

Having the post links immediately available would be super helpful for reading the comments while listening.
