@lucifargundam what i thought of is broad social experiments. like you can't really redo the first reality TV shows because people are too savvy about how those things play out. sure, not everyone saw "The Real World" or whatever but there's an awareness. could you redo the Stanford prison experiment? or the Milgram obedience experiment? how faithfully?
of course, people forget. so maybe not exactly "only once"
@2ck at this point I'd be concerned about social manipulation like what #google and #facebook have historically been caught doing.
If you want to prepare for such a thing, consider the upcoming presidential election. You have some time to put a ton of thought into it- and what you would like to try and do (or be ready for) during that timeframe.
Again, social manipulation is bad. But easy to do as repeatedly parroted by many #fediverse users on a few other non-#qoto servers.
