[Question] Is misinformation a serious problem, and is it tractable?

Longer title for this question: To what extent does misinformation/​disinformation (or the rise of deepfakes) pose a problem? And to what extent is it tractable?

  1. Are there good analyses of the scope of this problem? If not, does anyone want to do a shallow exploration?

  2. Are there promising interventions (e.g.certificates of some kind) that could be effective (in the important sense)?
