Thanks, I don’t know why I didn’t follow the footnote.
But if I had, I would have added to my comment that the cited paper confirms my expectations. The function that they describe (as in your quoted paragraph) does preserve ordering, and seems to have nothing to do with the compressive functions described at Wikipedia. (The paper also doesn’t use that term; the case-independent string ‘compr’ doesn’t appear in it at all.)
But actually, the point of the article seems to be that the function from reward magnitude to dopamine rate varies with time, being renormalised from time to time to be most sensitive (literally, having highest derivative) at the most likely inputs, which I did not get from your post at all. But if I were an editor, wanting your post to best reflect the article without getting any longer, I’d suggest just changing ‘compressive function’ to ‘variable function’ and removing the irrelevant link.
Not that any of this should detract from your otherwise excellent and everywhere interest post!

Gack! I’m just completely wrong about this one. Thanks for reading so closely and correcting my mistake!
You’re welcome then!
Upvoted.
Upvoted for reading closely and then reading a paper in the footnotes.
