One of the issues that has come up again and again in my reporting on misinformation and social media is the massive influence social media companies have on research in the field.

Last night a preprint dropped that tries to get at this with some numbers. My piece in @science.org (and 🧪🧵 coming):

Nearly a third of social media research has undisclosed ties to industry, preprint claims

Industry-linked studies were also more likely to focus on particular topics, suggesting these ties may be skewing the field

We analyzed 100 survey experiments fielded by TESS (tessexperiments.org), using only information from the proposals to identify intended hypotheses.

Here are some of the things we learned:
