All of Dan Wahl's Comments + Replies

To echo some of the other comments, I also think this kind of detailed, external "red teaming" of cost-effectiveness calculations is great in general, and I'd like to see more of it. As someone who has supported Sinergia in the past, I was concerned about some of the claims, and took a few hours to do some shallow research of my own. Tl;dr, my personal opinion of Sinergia hasn't changed much, pending their response.

To address the specific criticisms:

Hi Dan, thank you for your reply. Page 40-41 of Pig Watch 2024 indicates Alegra has not banned teeth grinding, and plans to follow Normative Instruction 113 (which allows teeth grinding in certain circumstances). Alegra is legally required to follow Normative Instruction 113.  Additionally, we noticed that you reference Sinergia’s Pigs in Focus quite a lot, and wanted to caution you that from what we’ve found, Pigs in Focus is not a reliable source.  For example, on page 30 of Alibem’s Sustainability Report, Alibem states they will “Maintain immunocastration instead of surgical castration – a procedure that was voluntarily eliminated from the Company’s protocols in 2010.” However, on page 20 of Pigs in Focus 2023, Sinergia indicates that in 2022 Alibem had not banned surgical castration, but in 2023 Alibem had banned surgical castration. Further, Sinergia took credit for getting Alibem to ban surgical castration “by 2023” (see Cell K4).  

Please consider using star score (or approval) voting next year instead of RCV

Yes, the Instant-Runoff/Hare form of RCV is a broken system that elects candidates based on incomplete information, which means it can eliminate the most-preferred candidates through vote-splitting. There are other ranked systems that are good, like Total Vote Runoff or Ranked Robin, but in an election like this with many candidates, it can be tedious to rank every one. A score-based ballot is probably a better choice, with less cognitive burden.  (Though STAR is specifically designed for single-winner elections, not 3-winner elections.  I'm not sure how well it performs in strategy-resistance in the multi-winner case.  They have a proportional multi-winner variant, too.)

I'm not an expert, but this may be a good idea. Apparently ranked-choice voting is always vulnerable to certain types of failures (https://en.wikipedia.org/wiki/Arrow%27s_impossibility_theorem), but these can be avoided with rated voting systems.

Hey Pat, thanks for the heads up. You're right that, despite working on desktop and via the LinkedIn mobile app, the search link doesn't seem to work on mobile browsers.

One quick workaround is to request the desktop site on the mobile browser, which seems to load properly on my side.

Excited to see this is returning for another year! A few notes:

- This year's match is (currently) "only" for up to $50,000 (for reference, last year a total of $620K was matched), and might not last very long
- See e.g. my Every.org profile for a list of ~75 EA-aligned orgs on the site (as of Nov. 2021)
- Note that you can fund your Every.org account straight from your DAF
- Here's last year's post, with some helpful info in the comments too

Yeah, people should probably do right on Nov. 1 if they want to get the match.

Ah! Ctrl+Enter does work in the Playground. I was doing most of my development in VS Code--not sure if it's also supposed to work there, but I don't see it in the keybindings.json.

Re: settings persistence in Playground, do they also come along with the share links? The critical ones for me would be Sample Count and the Function Display Settings.

Looking forward to auto-formatting as well!

Oh right, shortcut for VS Code is missing, filed. Share links are the only way settings persistence in the Playground works. But also for things such as Function Display Settings we eventually plan to support configuration through code and avoid adding too many UI settings (maybe even remove some).

Calculating up to annually_averted_health_dalys_time_discounted was taking me well over a minute in v0.3.0, but is down to ~5 seconds in v0.3.1--a big improvement!

I originally had to comment the actual model output (dollars_per_daly_equivalents_averted(20)) because it wouldn't return at all in v0.3.0, but now it's ~2 mins in v0.3.1.

For reference, the whole Causal model takes ~5 seconds to update.

NunoSempere
Now down to 1 min (55 seconds) in v.4. My guess is it's the maps and reduces, we should look whether we can optimize their implementation.

One such project, already underway, is our work on interspecies comparisons of moral weight.

FYI this link gives me an "Access Denied" error.

It should link to the section above, we'll fix it. Thanks!  

This is interesting, thanks for writing it up! I recently did an analysis of US cities (mostly looking for a wintering location, not a full move), and Tulsa ended up scoring relatively low, which was disappointing since I know there's a growing EA community there.

I'm really curious in your biking experience in particular, since that's the category where it fared the worst. I looked at bike commuter data, but I guess that's just a proxy for good commuter infrastructure, which is what I probably care about. Why do you think so few Tulsans bike at the moment?

Thanks for your thoughts, Dr. Wahl.   As alluded to in the post, biking is my form of transportation > 80%  of the time, and I wish I could single-handedly make the bike commute popular!! Theoretically, Tulsa is quite bikable because it's not too hilly or climatically extreme.   Traffic is not a big issue, and major roads tend to be wide / multilane.   I do tend to see more bike commuters when I'm downtown.  Less in Midtown (where I live) or Kendall-Whittier (another downtown-adjacent neighborhood). I think the primary barrier is cultural.   Tulsa is very tied up with the oil & gas industry, so it's not in the best interest of the elites to push green forms of transportation or increase the accessibility of public transit.  Accordingly, I think a lot of people take pride in having a nice car.  There's decent bike lane coverage.  I don't think they're used as often as they should be.  

I've been thinking about relocation recently too, though mostly through the lens of finding a better wintering location in the US. This post inspired me to at least upload (if not exactly document) my analysis to date. See here:

Originally I made a digital SSC podcast (feed) so that I could listen through the back catalog of posts (the human reader version didn't start until ~2017). I ended up getting used to the robot narrator, so I just kept it running on ACX. One small upside is that the digital versions get created within minutes of new posts.

This is great and you should make a LW post; these are in a really nice format for shunting around.  As a small nit: any idea why the first few essays of the Codex (https://www.lesswrong.com/codex) are not here?

david_reinstein
That makes sense. Still, I'm wondering if it might not be better to just continue the digital versions and put a link to the human reader ones, to clutter things up a little bit less. Or you might keep it up but put a link to the human reader version for people who might not know about it. It is certainly possible that some people actually prefer hearing a machine than a (particular) human. (Although his production value is very high, higher than mine was). By the way, as you probably know there's a reason why he doesn't record these until the day after the blogs come out: they are often adjusted/adapted and he wants to give some space for that to happen. On the other hand you could argue that people will just choose the version they prefer and we can trust the consumer here

This is awesome! I did something similar for Astral Codex Ten (feed, post) a while back. The human version is also good, if you like that kind of thing.

Why have a digital version if there is already an AC10 podcast with a human reader?

Here are a few other forum posts on the general topic of fiction and EA.

Along these lines, preventing childhood lead poisoning is another potential candidate.

Thanks for this (somewhat overwhelming!) analysis. I tried to do something similar a few years back, and am pretty enthusiastic about the idea of incorporating more uncertainty analysis into cost effectiveness estimates, generally.

One thing (that I don't think you mentioned, though I'm still working through the whole post) this allows you to do is use techniques from Modern Portfolio Theory to create giving portfolios with similar altruistic returns and lower downside risk. I'd be curious to see if your analysis could be used in a similar way.

cole_haus
Oh, very cool! I like the idea of sampling from different GiveWell staffers' values (though I couldn't do that here since I regarded essentially all input parameters as uncertain instead of just the highlighted ones). I hadn't thought about the MPT connection. I'll think about that more.

I've done a little work on this, using techniques from modern portfolio theory, and uncertainty estimates from GiveWell and ACE to generate optimal charity portfolios. See here for a background post, and here for my 2016 update.

Phil_Thomas
That’s interesting! I worked on something similar, but it only allows for normal distributions and requires pre-calculated returns and variances. Using the GiveWell estimates to create your own probability distributions is an interesting idea -- I spent some time looking through sources like the DCP2 and Copenhagen Consensus data but couldn’t find a source that did a good job of quantifying their uncertainty (although DCP2 does at least include the spread of their point estimates that I used for an analysis here ). One thing I wondered about while working on this was whether it made sense to choose the tangency portfolio, or just keep moving up the risk curve to the portfolio with the highest expected value (In the end, I think this would mean just putting all your money in the single charity with the highest expected value). I guess the answer depends on how much risk an individual wants to take with their donations, so a nice feature of this approach is that it allows people to select a portfolio according to their risk preference. Overall, this seems like a good way to communicate the tradeoffs involved in philanthropy.

Thanks, this is actually highly relevant to another piece I'm working on!
