I'll make two observations.
Again, from a recent issue of Nature, we may be misperceiving the volume of misinformation on social media. We may be overestimating it. This is why it's important for researchers to have access to these data to maintain the ability to detect flexibly mis- and disinformation, but we may be overestimating the prevalence of misinformation. My colleagues at the Media Ecosystem Observatory measure the prevalence of misinformation in a certain way, and that estimate strikes me as rather low. That's available in their monthly situation reports. That's one area.
The second is the causal relationship. We might imagine or fear, indeed, that social media misinformation is polarizing people, but the alternative possibility is that people with extreme views are exposed to social media misinformation. That kind of uncertainty is important to address through high-quality, public, scientific research on an ongoing basis, because it is a moving target. This technology is changing, so sustained attention is required in Canada. A lot of this research is in the United States, and Canada is not the United States. Research in Canada is very much necessary here as well.
