This is blogspam. Here's the original post: https://patrickcollison.com/pollution

That would be a much better link than the one provided. Wasting energy on the "IQ" issue is not productive to the problem presented: that air pollution does, indeed, cause (hopefully only temporary) cognitive decline. It can be measured on a small scale, for example, see the Allen et al. [1] article showing cognitive decline in an office environment (conventional building vs Green+ building).

Should I upvote despite that, or wait for somebody to post the original? I'm not sure of HN's norms here.

Better not to post the original if there's already an active thread, because that will either have no effect or split the discussion. We usually change URLs in cases like this. Best is to email hn@ycombinator.com because then we're sure to see it.

You can upvote and also email the mods using the Contact link in the footer; they can swap out links easily.

Wasn't the original link already posted under - https://news.ycombinator.com/item?id=21560916 yesterday?
