Selective Exposure to Misinformation: Evidence from the consumption of fake news during the 2016 U.S. presidential campaign, Andrew Guess, Brendan Nyhan, and Jason Reifler


Though some warnings about online “echo chambers” have been hyperbolic, tendencies toward selective exposure to politically congenial content are likely to extend to misinformation and to be exacerbated by social media platforms. We test this prediction using data on the factually dubious articles known as “fake news.” Using unique data combining survey responses with individual-level web traffic histories, we estimate that approximately 1 in 4 Americans visited a fake news website from October 7-November 14, 2016. Trump supporters visited the most fake news websites, which were overwhelmingly pro-Trump. However, fake news consumption was heavily concentrated among a small group — almost 6 in 10 visits to fake news websites came from the 10% of people with the most conservative online information diets. We also find that Facebook was a key vector of exposure to fake news and that fact-checks of fake news almost never reached its consumers.

Educational opportunity in early and middle childhood: Variation by place and age, Sean F. Reardon


I use standardized test scores from roughly 45 million students to describe the temporal structure of educational opportunity in over 11,000 school districts—almost every district in the US. For each school district, I construct two measures: the average academic performance of students in grade 3 and the within-cohort growth in test scores from grade 3 to 8. I argue that third grade average test scores can be thought of as measures of the average extent of educational opportunities available to students in a community prior to age 9. Growth rates in average scores from grade 3 to 8 can be thought of as reflecting educational opportunities available to children in a school district between the ages of 9 and 14.

I document considerable variation among school districts in both average third grade scores and test score growth rates. Importantly, the two measures are uncorrelated, indicating that the characteristics of communities that provide high levels of early childhood educational opportunity are not the same as those that provide high opportunities for growth from third to eighth grade. This suggests that the role of schools in shaping educational opportunity varies across school districts. Moreover, the variation among districts in the two temporal opportunity dimensions implies that strategies to improve educational opportunity may need to target different age groups in different places. One additional implication of the low correlation between growth rates and average third grade scores is that measures of average test scores are likely very poor measures of school effectiveness. The growth measure I construct does not isolate the contribution of schools to children’s academic skills, but is likely closer to a measure of school effectiveness than are measures of average test scores.

Tax Bill Would Increase Abuse of Charitable Giving Deduction, with Private K-12 Schools as the Biggest Winners, Carl Davis

From Executive Summary

In its rush to pass a major rewrite of the tax code before year’s end, Congress appears likely to enact a “tax reform” that creates, or expands, a significant number of tax loopholes. One such loophole would reward some of the nation’s wealthiest individuals with a strategy for padding their own bank accounts by “donating” to support private K-12 schools. While a similar loophole exists under current law, its size and scope would be dramatically expanded by the legislation working its way through Congress.2 This report details how, as an indirect result of capping the deduction for state income taxes paid, the bill expected to emerge from the House-Senate Conference Committee would enlarge a loophole being abused by taxpayers who steer money into private K-12 school voucher funds. This loophole is available in 10 states: Alabama, Arizona, Georgia, Kansas, Montana, Oklahoma, Pennsylvania, Rhode Island, South Carolina, and Virginia.

The Sound of White Silence, @michaelharriot

White is a blank space.

It is the unwritten adjective that filled the infinite and simultaneously minuscule void between “all” and “men” when our founding fathers so eloquently declared their independence. The word “white” is not included in the Constitution, but it is understood by all to be the unmentioned modifier in “we the people.” It is our national equivalent to the aphonic letter “e.” We could always see it, but as a country we agreed to adhere to the first rule of American phonetics:

The “white” is silent.

The Nature and Aim of Fiction, Flannery O’Connor

People have a habit of saying, “What is the theme of your story?” and they expect you to give them a statement: “The theme of my story is the economic pressure of the machine on the middle class”—or some such absurdity. And when they’ve got a statement like that, they go off happy and feel it is no longer necessary to read the story.

Some people have the notion that you read the story and then climb out of it into the meaning, but for the fiction writer himself the whole story is the meaning, because it is an experience, not an abstraction.
