New in Scientific American w Jenny Allen: Is misinformation *really* a problem? Our take= Exposure to "fake news" is rare, but misinformedness is common- b/c of misleading claims from elites & mainstream news. Solutions must take this into account! www.scientificamerican.com/article/comb...

Combating Misinformation Runs Deeper Than Swatting Away ‘Fake News’
Combating Misinformation Runs Deeper Than Swatting Away ‘Fake News’

“Fake news”-style misinformation is only a fraction of what deceives voters. Fighting misinformation will require holding political elites and mainstream media accountable

One of the more interesting paragraphs from Nate Cohn’s article today: Online pollsters have basically found ‘one weird trick’ to get reasonable looking results. Gift link: nytimes.com/2024/09/27/u...

Another possibility is the rise of recalled vote weighting, where the pollster asks how respondents voted in the last election and then adjusts the sample to match the actual result of that election. This month, more than 80 percent of online opt-in polls weighted on recalled vote, compared with about 10 percent of other kinds of polls.
There's a reason pollsters rely on it: It's a bludgeon, allowing them to hammer even the worst sample into the ballpark of a plausible result.
