There's an old saying in Tennessee ...
Fool me once ... you can't get fooled again! (or video from getty images canada)
And so, here, if we look at the results of GSS regression on p.36+ (of the article linked under "pre-print paper"), it seems that (p-value) the Generative Agent can't reliably predict your Age if it is between 18 and 34, or 65 and more, nor can it predict your Political Ideology if you are any sort of Conservative, neither your Race nor Ethnicity unless you are Black or African American, nor your Income whatever that might be ... (if I understand well, which is debatable ... !)
Earlier, on pages 31 to 34, we also find that the Agent has a hard time replicating one's wlthblks, parsol, kidssol, spanking, discaffw, discaffm, and xmarsex for some reason, not to mention the negatively correlated polabuse/y and usewww*! Still (p.34), it's great at figuring out your crucial dwclown, zodiac, and sex*!
With such major advance, it seems fair to paraphrase Louis Armstrong's brother Neil, and consider this to be "one small step for [the RotM], one giant leap [to conclusions] for [boffins]", IMHO! (except for my cavalier misinterpretations, of course!)
