Due to popular demand, we're publishing a list of concrete outputs that hotel residents have made during their stay.

Note that interpreting this list comes with some caveats:

  • While the output per dollar is very high, this might not be the best metric. As an intuition pump, consider that sending an EA to prison has a higher output/$ ratio than the EA hotel, because it's free. The best metric would be marginal output divided by marginal output for a counterfactual donation, but this is hard to estimate. As a proxy, we suggest looking at output per day per person. Does this seem high compared to an average EA?
  • This list doesn't cover everything of value that has been supported by the hotel. Some residents have spent months working on things that they haven't published yet. Some of them have spent most of their time doing self-therapy. Some of them have been reading books. Some of them have been having a lot of research conversations. Some have been developing presentations and workshops. The hotel is in a unique position to support this kind of hard-to-verify work.

Most of the data is in. We will keep an up to date version of this post live at eahotel.org/outputs.

Total expenses as of March 2019

Money: So far ~£66,500* has been spent on hosting our residents, of which ~£7,600 was contributed by residents.

Time: ~4,000 person-days spent at the hotel.

Our Ask

Do you like this initiative, and want to see it continue for longer, on a more stable footing? Do you want to cheaply buy time spent working full time on work relating to EA, whilst simultaneously facilitating a thriving EA community hub? Do you want to see more work in the same vein as the above? Then we would like to ask for your support.

We are very low on runway. Our current shortfall is ~£4k/month from July onward.

To donate, please see our GoFundMe or PayPal Money Pool, or get in touch if you'd like to make a direct bank transfer (which will save ~3% on fees and up to 3% on currency conversion if using a service like Revolut or Transferwise).

If you’d like to give regular support, we also have a Patreon.

(BTW note that Saulius is an employee of Rethink Charity as well as Derek, and wrote those two posts while working with us.)

This would seem a solid enough record to be in the ballpark of other exploratory grants that are being made. Is EA Hotel applying with the various funds for a grant?

They applied to the Long Term Future Fund April 2019 grant round, and were rejected.

(This is just my personal perspective and does not aim to reflect the opinions of anyone else on the LTF-Fund)

I am planning to send more feedback on this to the EA Hotel people.

I have actually broadly come around to the EA Hotel being a good idea, but at the time we made the grant decision there was a lot less evidence and writeups around, and it was those writeups by a variety of people that convinced me it is likely a good idea, with some caveats.

Probability of out-of-cycle grant consideration for the EA Hotel, given that they're in a funding crunch & you've broadly come around to thinking that it's a good idea?

I think sadly pretty low, based on my current model of the time constraints of everyone, and also CEA logistical constraints.

Maybe EA Grants will be up-and-running in time to make a difference? (I'll check with Nicole.)

fwiw, I personally give it >75% probability that we will be able to survive at least until next round

It would be helpful if you could also list how long each person stayed at the hotel. Some of these people seem to have produced very little for 10 months, but maybe they were only there for one month!

I would rather not. This would pressure people into goodharting their projects for legibility, which is one of the things our setup is supposed to prevent.

(tldr: an agent is legible if a principal can easily monitor them, but it limits their options to what is easy for the principal to measure, which might reduce performance)

Quite a few of our guests are not even on this list, but this doesn't mean they're sitting around doing nothing all day. They're doing illegible work that is hard or even impossible to evaluate at a distance. I put a few examples in the second caveat of the post.

(I realise this is at odds with the EA maxim of measuring outcomes. That's why we published this post: so the hotel could at least be evaluated in aggregate. I think it's neat that people with illegible work can hide behind legible ones)
