Picking up on the observation that "Getting it less wrong" is, of course, applicable...to the idea itself...
There's something going on here I can't quite get a handle on/get my head around: an archiving-and-preservation of over 20 years' repetition of a phrase that itself encourages alteration and revision. The form doesn't accord w/ the function, the style w/ the content. There's a "stuckness" to the whole enterprise that I'm curious about. There's a stuckness in particular to the repeated insistence that "less wrong" and "more right" do not in fact require one another. The brain (my brain anyway) works associatively as well as logically; whatever the intention, the phrase "less wrong" persistently connotes/attaches to/evokes an association of "right."
What makes all this so curious is that what's always stuck in my craw about this concept is precisely the reverse of being stuck: the presumption (even in the newest and helpful re-formulation, "noticing and correcting a mismatch") of progress. Since progress is only/always in the eye of the observer, and only/always contextual (i.e.: dependent on a particular frame/point-of-view), I find "getting it progressively less wrong" a "less useful" and less "efficient" way of describing science, and intellectual work, and the general telling of stories than a description that "offers a different point of view," or "highlights some connections, while neglecting others," or "foregrounds some aspects, while assigning others a background position."
For example: a decision to drop out of school is a different thing to do than continuing studying. It is not "fixing a wrong"; it's not "less wrong" than staying in; it's not "progress" (at least not without defining what one's values are: escaping the system? getting ahead in it?). Ditto a decision to end a friendship, start a new job, change a place of residence. By what calibration can such decisions be said to be "less wrong"? Or--to take a classic science story, the re-description of the solar system, from earth-centered to heliocentric, as judged by the Little Monk in Brecht's Galileo--
What would happen if one did not begin with belief? Could one even begin?
