Graceful recovery is more impressive, and useful to the community as a whole, than not having slipped up in the first place.

Perhaps a loss due to not paying attention, but I think making a rapid correction based on criticism is worthy of some amount of karma, even on something trivial. I've misunderstood loads of things and felt stupid every single time, and I do believe it helps some amount to see someone else publicly brush the dirt off here and there. For me one of the hallmarks of lousy dialogue quality is that it seems like 100% of participants either believe they have 0% error rate or that they cannot brush it off publicly for emotional reasons.

Beware my opinion though, it is possible that seeing you do something against my views, then later retract and agree with my views makes me feel good. I am sorry to say that it is difficult for me to tell if that is playing a significant role or if I am some sort of dialogue connoisseur. Perhaps more likely is that it is some finicky combination. Or even more insidiously, I could be pointing this out to try and seem more aware than I am. Oh how bias is like a six-headed, head-regenerating dragon.
