So, it's clear that a small subpopulation is preferentially tweeting links to sources of misinformation, and for many users, they're the most significant source of exposure to these sites. So who are these people?
They're a bit more likely to be female. While both the comparison groups were roughly evenly split between male and female, the superspreaders were 60 percent female. They're also older, on average 58 years old, nearly 20 years older than the sample as a whole. And, while much of the misinformation about the election largely circulated within Republican circles, only 64 percent of the superspreaders were registered Republicans (nearly 20 percent were registered as Democrats).
In other words, we have too much money.
