Why not offer a multi-million / billion dollar prize for solving the Alignment Problem?

My colleagues have often been way too nice about reading group papers, rather than the opposite. (I’ll bet this varies a ton lab-to-lab.)

Why not offer a multi-million / billion dollar prize for solving the Alignment Problem?

I like the TruthfulQA idea/paper a lot, but I think incentivizing people to optimize against it probably wouldn't be very robust, and non-alignment-relevant ideas could wind up making a big difference. 

Just one of several issues: The authors selected questions adversarially against GPT-3—i.e., they oversampled the exact questions GPT-3 got wrong—so, simply replacing GPT-3 with something equally misaligned but different, like Gopher, should yield significantly better performance. That's really not something you want to see in an alignment benchmark.

Managing COVID restrictions for EA Global travel: My plans + request for other examples

Related question: EAG now requires you to have a lateral flow test result within 48h of the start of the event.  Am I correct in understanding that lateral flow tests in the UK are often DIY kits, where  you don't get any formal documentation of the results? If so, does anyone know what kind of documentation/evidence the EAG staff will be looking for?

This is great!

  • Why the Randox test in particular?
  • Does it seem viable to use the Day 2 test as the US return test? (I'll only be there Thursday to Monday, so a test on Saturday satisfies both requirements, if there's no other catch.)

Naïve question: What's the deal with the cheapest CO2 offset prices?

It seems, though, that the current price of credible offsets is much lower than the social cost of carbon, and possibly so low that just buying offsets starts to look competitive with GiveWell top charities.

I'm not an expert on this. (I run an offsetting program for a small organization, but that takes about 4h/year. Otherwise I don't think about this much.) I'm also not anywhere near advocating that we should sink tons of money into offsets. But this observation strikes me as unintuitive enough that I suspect I'm missing something.

Cost of offsetting:
I've generally seen the UN FCCC's carbon offset market presented as credible, if not the biggest or most scalable. They make it pretty easy direct money to specific projects, and most of them pass the smell test as being both verifiable and additive. One project that popped up last year involved converting the operations of a platinum mining company in Bihar from burning coal to another burning another fossil fuel in a slightly-lower-emissions way. That's easy to verify, and there was a clear argument for why it wouldn't make economic sense for them to transition without the offset money.

Current prices on that market are around $1.75/tonne, and at other times of year recently, I've seen numbers dip as low as ~$0.33/tonne.

Value of offsetting:
My impression is that the social cost of carbon is somewhere in the $30–300/tonne range, suggesting that cheap credible offsets are plausibly pretty high-leverage, but I don't have good framework for thinking about this kind of impact.

I found this easier to visualize in light of this line from a recent Future Perfect piece:

[...] Bressler found that adding 4,434 metric tons of carbon dioxide into the atmosphere would result in one heat-related death this century.

Combining that with the numbers above yields a price-per-life-saved in the $1k-10k range, which is within the same order of magnitude as charities like AMF, IIRC.

What am I missing? Is there something fishy with that use of of dollars per life saved? Are these cheap UN-monitored offsets actually bullshit? Or is it actually just very impactful to buy this kind of offset while they're still cheap (...even if it's still not the most effective way to spend money, or even the most effective way to spend money on climate impacts)?

Is shareholder activism worth it?

Update: It seems like the new VOTE ETF could be significantly cheaper and significantly higher-impact than the alternatives I'd mentioned, though still not overtly EA-oriented. Any thoughts?

How to run a high-energy reading group

Riffing on this, there's an academic format that I've seen work well that doesn't fit too neatly into this rubric:

At each meeting, several people give 15-30m critical summaries of papers, with no expectation that the audience looks at any of the papers beforehand. If the summaries prompt anyone in the audience to express interest or ask good questions, the discussion can continue informally afterward.

This isn't optimized at all for producing new insights during the meeting, but I think it works well in areas (like much of AI) where (i) there's an extremely large/dense literature, (ii) most papers make a single point that can be summarized relatively briefly, and (iii) it's possible to gather a fairly large group of people with very heavily overlapping interests nad vocabulary.

This is probably overstated—at most major US research universities, tenure outcomes are fairly predictable, and tenure is granted in 80-95% of cases. This obviously depends on your field and your sense of your fit with a potential tenure-track job, though.

That said, it is much easier to do research when you're at an institution that is widely considered to be competitive/credible in your field and subfield, and the set of institutions that gets that distinction can be smaller than the (US) top 100 in many cases. So, it may often make sense to go for a postdoc if you think it'll increase your odds of getting a job at a top-10 or top-50 institution.

Estimation of probabilities to get tenure track in academia: baseline and publications during the PhD.

Academic here:

  • Essentially all of these numbers vary wildly  across subfields, across countries, and on other assumptions like how prestigious the labs are that you're considering. Judging based on numbers from physics, or from US PhDs overall, could leave you off by an order of magnitude or more. They also vary significantly over time. 
  • The populations in PhD programs vary a lot from field to field as well, and how you fit relative to those populations will help tilt the odds. Being intrinsically motivated and a good English writer (the two things I can tell about the OP) could give you a pretty big leg up in your odds of finishing and getting a job relative to the median CS PhD student at a good US research university, at least assuming that you have the technical qualifications to be admitted. In a Philosophy program, by contrast, that'd be baked into the admissions criteria, and wouldn't tell me much.
  • FWIW, here are some ballpark 80% confidence intervals based only on my recent experience. These are conditioned on what I know about the OP (AI safety area, good English writer, intrinsically motivated). I'm focusing on the US because that's what I know, and I'm generally assuming top-50-or-so universities in CS, which is where you can be reasonably confident that you'll have the resources and public platform to do high-impact research. I work in AI, but I don't have much yet experience with AI safety. I have been involved in general admissions for two PhD programs with an AI focus, and two others.
    • P(admission to a good PhD program | serious effort at applying) = 
       1-15% without substantial prior research experience, 
       5-60% with limited research experience (at least one serious paper with a recognized collaborator, but nothing presented as a first author at a competitive venue)
       50-90% with strong research experience (at least one paper with a recognized collaborator, presented as a first author at a competitive venue).
    • P(graduate within six years | enroll) = 70-95%
    • P(assistant professor job at a US top-100 research university directly after PhD | graduate within six years and apply) = 5-50%
      P(assistant professor job at a top-100 research university  within three years after PhD | graduate within six years and apply) = 30-75%
      P(long-term US research job that supports publishing, academic or otherwise, within three years after PhD | graduate within six years and apply) = 85-95%
    • P(granted permanent tenure within nine years of starting as an assistant professor | make a serious attempt to stay) = 85%-98%
Is shareholder activism worth it?

Thanks, Wayne!

This looks like a good starting point for further research, but it's hard to take much that's actionable from this without more background in finance. Is there anything you'd take away as advice to a smallish-scale individual investor?
