The thing we can indirectly conclude is that “social identity” (“when I talked to … genuinely didn't identify as”) and “personal identity” (whatever that is) can be (at least intuitively) separate.

There's something about subjective perception consituting facts and bridge hypotheses having a validity measure (based on prediction of those facts) despite being “subjective”; but I can't make a better formulation either.

And there's also something about “I now resolve to prefer red wine” possibly working in the same way as “I now set my desktop background to white” (and possibly failing just as well).
