The authors tacked on a mini-survey to DX's regular survey offering, limiting participants to people who work at orgs willing to pay for DX's survey offering. It was not extraordinarily expensive, but the fact that they as recently as a month ago had public pricing and no longer do suggests it's probably more than it was at something like $15 PUPM.

I'm a bit pessimistic that much of this research is being driven by large orgs in collaboration with researchers who aren't sufficiently independent. That's not to say that this sort of work isn't valuable, or that the research is fraudulent, but many people who work on software don't work for these sorts of orgs, and it's not clear to me how those people will be able to participate in research going forward.

Much of this work also feels like it's becoming the industry equivalent of something like the Social Determinants of Health[1]. People with greater job satisfaction and more uninterrupted time are more productive? Is that the best we can do?
