EA Hotel fundraiser 4: concrete outputs after 10 months

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.

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.
