+I thought the "you could not have generated the answer I just told you" gambit was a pretty dirty argumentative trick on Yudkowsky's part. (Given that I could, how would I be able to prove it?—this was itself a good use-case for concealing spoilers.)
+
+As it happened, however, I _had_ already considered the case of spoilers as a class of legitimate infohazards, and was prepared to testify that I had already thought of it, and explain why I thought hiding spoilers were relevantly morally different from the coverups I was objecting to. The previous night, 7 December 2022, I had had a phone call with Anna Salamon,[^evidence-of-independent-generation] in which I (remembered that I) had cited dath ilan's [practice of letting children figure out heliocentrism for themselves](https://www.glowfic.com/replies/1777588#reply-1777588) as not being objectionable in the way the sadism/masochism coverup was.
+
+[^evidence-of-independent-generation]: I was lucky to be able to point to Anna as a potential witness to defend myself against the "could not have generated" trick—as a matter of principle, not because I seriously expected anyone to care enough to go ask Anna if she remembered the conversation the same way.
+
+ I also mentioned that when I had used spoiler blocks on the _Atlas Shrugged_ quote I had posted upthread, I had briefly considered making some kind of side-remark noting that the spoiler blocks were also a form of information-hiding, but couldn't think of anything funny or relevant enough (which, if my self-report could be trusted, showed that I had independently generated the idea of spoilers being an example of hiding information—but I didn't expect other people to uncritically believe my self-reports).
+
+It seemed like the rationale for avoiding spoilers of movie plots or homework exercises had to do with the outcome being different if you got spoiled: you have a different æsthetic experience if you experience the plot twist in the 90th minute of the movie rather than the fourth paragraph of the _Wikipedia_ article. Dath ilan's sadism/masochism coverup didn't seem to have the same structure: when I try to prove a theorem myself before looking at how the textbook says to do it, it's not because I would be _sad about the state of the world_ if I looked at the textbook; it's because the temporary ignorance of working it out myself results in a stronger state of final knowledge.
+
+That is, the difference between "spoilers" (sometimes useful) and "coverups" (bad) had to do with whether the ignorant person is expected to eventually uncover the hidden information, and whether the ignorant person knows that there's hidden information that they're expected to uncover. In the case of the sadism/masochism coverup (in contrast to the cases of movie spoilers or homework exercises), it seemed like neither of these conditions pertained. (Keltham knows that the Keepers are keeping secrets, but he seems to actively have beliefs about human psychology that imply masochism is implausible; it seems more like he has a false map, rather than a blank spot on his map for the answer to the homework exercise to be filled in.) I thought that was morally relevant.
+
+(Additionally, I would have hoped that my two previous mentions in the thread of supporting keeping nuclear, bioweapon, and AI secrets should have already made it clear that I wasn't against _all_ cases of Society hiding information, but to further demonstrate my ability to generate counterexamples, I mentioned that I would also admit _threats_ as a class of legitimate infohazard: if I'm not a perfect decision theorist, I'm better off if Tony Soprano just doesn't have my email address to begin with, if I don't trust myself to calculate when I "should" ignore his demands.)
+
+As for the claim that my thinking was distorted and I was arguing instead of seeing, it was definitely true that I was _motivated to look for_ criticisms of Yudkowsky and dath ilan, for personal reasons outside the scope of the server, and I thought it was great for people to notice this and take it into account. I hoped to nevertheless be competent to only report real criticisms and not fake criticisms. (Whether I succeeded, of course, was up to the reader to decide.)
