I would highlight at least two on there and one that's not on there.
The two that I would highlight are supporting local journalism and supporting media literacy programs. I mention those not because they're better or worse than the others, but because they have a higher ceiling. They could accomplish more over time than many of the other more small-bore measures that we're already highly invested in, which are more tactical in nature.
The third recommendation that I would make is a meta-recommendation. It's that we need to get better at informing ourselves about these informational dynamics and threats. That would start with, for example, helping researchers get better access to information from tech platforms and creating grants and other pathways to ensure this research actually occurs.
