      Here's the actual cumulative review time, rising roughly linearly (as we'd expect) with the number of repetitions.pic.twitter.com/GcbN9tjGoU

      Interestingly, as questions are repeated, people seem to get a little faster at answering them. Here's the marginal review time, showing a slight decrease.pic.twitter.com/2ieATLswPV

      That is, the marginal review time is going down, even though the time between reviews is increasing exponentially.

      Similarly, the accuracy is getting better with repetition, even with the time between reviews increasing exponentially. At least in this sense, people are becoming more fluent.pic.twitter.com/UeGQPdT1Di

      All very preliminary, of course, and there are many significant issues (esp. selection effects!) which we're working to address in other ways. Still, it's encouraging!

      One curious thing about this demonstrated retention vs review repetitions plot: at 5 reviews, almost everyone who sticks with it has 2.5k days of demonstrated retention. For a worst-case outcome, that seems v encouraging!pic.twitter.com/WBaeqe4bJ3

      Of course, "everyone who sticks with it" is a significant caveat. Maybe people who aren't going so well give up? We're investigating whether that might be the case or not.

      Another curious thing: the people scoring almost zero percent accuracy in the bottom left here. Again, something we're going to look into!pic.twitter.com/fz43OCYRM0

      I suspect, though, that it will turn out to be people using the system in an unusual way. E.g., in the body of the essay we advise people to delight in transgressive uses!pic.twitter.com/EimKoz5vXp

      (Someone running a citizen science project once told me they had a small stream of transgressive users - people who were completely ignoring the point of the project, and "doing things wrong" for their own delight.)

      Another fun tidbit: by repetition 5, almost everyone is getting 90+% of the questions right. It'd be nice to also better understand (a) what's happening for the other users; and (b) how honest people feel they are being (and actually are)?pic.twitter.com/HNm1t1WPph

          It just occurred to me that by strongly encouraging people to engage in transgressive uses, we're putting determined contrarians in a bind. To be transgressive they need to do exactly as we ask 😀

          I'm curious if the same questions are right/wrong by all people of if everyone gets different questions wrong

          I sometimes grade myself as "correct" for mostly correct answers, but I tend to be very honest to myself and the review process. I have read both qcfvc and the quantum search pages and am looking forward to my next review session. In fact, it's one of the 1st things to look for!
