Whatever we do on social media regulation, let’s accompany it with rigorous social science and platform transparency so that we can learn about the effects and improve iteratively.

I *love* the introduction to this new handbook. Yes to it all.

Sounds obvious but important in light of prior claims algorithms don't cause attitudinal changes.

We should view Social Media as a systemic issue instead of a symptomatic one and tackle its root:
