Affective Polarization or Partisan Disdain?: Untangling a Dislike for the Opposing Party from a Dislike of Partisanship
"Relying on two national experiments, we demonstrate that although some Americans are politically polarized, more simply want to avoid talking about politics. In fact, many people do not want their child to marry someone from their own party if that hypothetical in-law were to discuss politics frequently."
Implementing the flipped classroom: an exploration of study behaviour and student performance
Surprise, surprise: Looks like flipped classroom environments - which swap the venue in which traditional teaching and "homework" are done - are overhyped.
Chinese surveillance programme mines data from workers’ brains
Sounds kind of creepy. "Concealed in regular safety helmets or uniform hats, these lightweight, wireless sensors constantly monitor the wearer’s brainwaves and stream the data to computers that use artificial intelligence algorithms to detect emotional spikes such as depression, anxiety or rage." Brought back to mind the social credit system being implemented in China

Heat and Learning
"We provide the first evidence that cumulative heat exposure inhibits cognitive skill development and that school air conditioning can mitigate this effect. Student fixed effects models using 10 million PSAT-takers show that hotter school days in the year prior to the test reduce learning, with extreme heat being particularly damaging and larger effects for low income and minority students. ... New data providing the first measures of school-level air conditioning penetration across the US suggest such infrastructure almost entirely offsets these effects."
Experiential or Material Purchases? Social Class Determines Purchase Happiness
"Across multiple studies using a range of methodologies, we found that individuals of higher social class, whose abundant resources make it possible to focus on self-development and self-expression, were made happier by experiential over material purchases. ... lower-class individuals were made happier from material purchases or were equally happy from experiential and material purchases."
Did Rwanda’s Paul Kagame trigger the genocide of his own people?
"Millions of lives were lost in the ethnic and political violence that embroiled Rwanda in the 1990s. Rwanda’s current president Paul Kagame was initially hailed as a hero for stopping the genocide, but, as Canadian journalist Judi Rever reveals in her new book, the truth is much darker".

"Why Trump won and could win again"

Would recommend the following as a commentary on a lot of the research and analysis you'll find done by academics and promoted in the popular media on the subject of Trump and those who voted for him:

The above conversation is also available in MP3 format on the corresponding BloggingHeads page - which will allow you to focus in on particular parts of the discussion. You can find a summary of al-Gharbi's research "Race and the race for the White House: On social research in the age of Trump" here.

Too much of what passes for in-depth analysis on any issue with a "social justice" connection these days seems like the sort of thing done by "the hedgehog, who knows one big thing, toils devotedly within one tradition, and imposes formulaic solutions on ill-defined problems" (to quote the description of the 2nd edition of Philip Tetlock's book Expert Political Judgment: How Good Is It? How Can We Know?). That's precisely the sort of analysis which, based on Tetlock's analysis, you should expect to find with gaping holes and proving relatively unreliable.
