No news is bad news
Political scientists analyzed news stories from the biggest newspaper in each congressional district before the 2010 and 2014 elections. Coverage of House races declined noticeably from 2010 to 2014, even controlling for how competitive each race was. Furthermore, survey respondents in these districts expressed less knowledge of the races, and less of an intention to vote in them, even controlling for changes in campaign spending and the respondent’s partisanship.

Hit me baby one more time
In several experiments, University of Chicago psychologists presented people with choices between gambles, where one gamble was objectively superior but not intuitively so. Participants were explicitly told which gamble was objectively superior. (For instance, when a blackjack dealer is showing a 4, a player with a 9 and a 4 has a higher chance of winning by standing than by hitting — even though a player might instinctively think 13 won’t be enough to win a hand.) Yet even after acknowledging the gamble that was objectively superior, a significant fraction of participants chose the objectively inferior gamble.

In experiments, young French women who were subliminally exposed (for only 20 milliseconds) to images of thin female models subsequently reported greater anxiety about their bodies. This effect was just as real for those who had initially reported being satisfied with their bodies.

Country before party
Partisan Americans who were asked to read or write about the strengths of America subsequently reported being more positive about the opposing party. Likewise, Americans were more positive about the opposing party’s presidential candidate when interviewed around July 4 or the Olympics.

Comparing the timing of car safety recalls with the timing of automotive ad spending in newspapers, economists found that a newspaper was less likely to cover a recall when the manufacturer had spent more on ads in that newspaper over the previous couple of years — especially when the recall was bigger, where there were fewer competing newspapers, and where Craigslist was siphoning classified ad revenue. This may have cost lives, as greater coverage of a recall was associated with fewer fatalities involving the manufacturer’s vehicles.
