Thanks for sharing!
I was wondering what is the likelihood of the results being a fluke, so I calculated the p-value for the null hypothesis that the true means of the scores respecting the question “Overall, how much did you like this content?” for Steinhardt (S) and Gates (G) were equal.
- Assumption: S and G follow normal distributions.
- Sample sizes. n_S = n_G = 29.
- Sample means. mu_S = 5.7. mu_G = 5.4.
- Standar errors of the sample means. SE_S = SE_G = 0.2.
- T-score: t = (mu_S - mu_G)/(SE_S^2 + SE_G^2)^0.5 = 1.06.
- Degrees of freedom: D = n_S + n_G - 2 = 56.
- P-value: 2*(1-T.DIST(t, D, 1)) = 29.3 %.
The value will be lower if we compare Steinhardt with authors which got a lower mean score. I guess it would be nice to include some statistical analysis of this type into the report, such that it is easier to quickly assess how robust are the conclusions.
Really interesting stuff! Another question that could be useful is how much each piece shifted their views on existential risk.
Some of the better liked pieces are less ardent about the possibility of AI x-risk. The two pieces that are most direct about x-risk might be the unpopular Cotra and Carlsmith essays. I’m open to the idea that gentler introductions to ideas about safety could be more persuasive, but it might also result in people working on topics that are less relevant for existential safety. Hopefully we’ll be able to find or write materials that are both persuasive to the ML community and directly communicate the most pressing concerns about alignment.
Separately, is your sample size 28 for each document? Or did different documents have different numbers of readers? Might be informative to see those individual sample sizes. Especially for a long report like Carlsmith’s, you might think that not many readers put in the hour+ necessary to read it.
Edit: Discussion of this point here: https://www.lesswrong.com/posts/gpk8dARHBi7Mkmzt9/what-ai-safety-materials-do-ml-researchers-find-compelling?commentId=Cxoa577LadGYwC49C#comments
(in response to the technical questions)
Mostly n=28 for each document, some had n =29 or n= 30; you can see details in the Appendix, quantitative section.
The Carlsmith link is to the Youtube talk version, not the full report -- we chose materials based on them being pretty short.
Was each piece of writing read by a fresh set of n researchers (i.e. meaning that a total of ~30*8 researchers participated)? I understand the alternative to be that the same ~30 researchers read the 8 pieces of writing.
The following question interests me if the latter was true:
Do you specify in what order they should read the pieces?
I expect somebody making their first contact with AIS to have a very path-dependent response. For instance, encountering Carlsmith first and encountering Carlsmith last seem to produce different effects—these effects possibly extending to the researchers' ratings of the other pieces.
Unrelatedly, I'm wondering whether researchers were exposed only to the transcripts of the videos as opposed to the videos themselves.
No, the same set of ~28 authors read all of the readings.
The order of the readings was indeed specified:
Researchers had the option to read the transcripts where transcripts were available; we said that consuming the content in either form (video or transcript) was fine.
