Absolutely brilliant work here by @douglasguilbeault.bsky.social. More broadly, so delighted to see outlets like @nature.com willing to publish such important CSS research.
I am without the words to describe how thrilled our team is to see our paper selected for the cover of @Nature! As the tagline captures, we hope our study empowers others to see how tools in computational social science can provide critical "reality checks" for our social world! @nature.com

Big shoutout to Patrick Prag @ppraeg.bsky.social !!
Yes I am an editor too, you may thank me, even if you believe my rejection of your paper was dumb and unfair.
So, I said it. Back to reading the next shitty paper.
