Effective of changes in urban density from the London Blitz and the building/destruction of the Berlin Wall
To quote from the latter: "Theory and empirical evidence confirm the positive relationship between urban density and productivity in a virtuous circle of ‘cumulative causation’."
Brahmin Left vs Merchant Right: Rising Inequality & the Changing Structure of Political Conflict
"In the 1950s-1960s, the vote for left-wing (socialist-labour-democratic) parties was associated with lower education and lower income voters. It has gradually become associated with higher education voters, giving rise to a “multiple-elite” party system in the 2000s-2010s: high-education elites now vote for the “left”, while high-income/high-wealth elites still vote for the “right” (though less and less so). I argue that this can contribute to explain rising inequality and the lack of democratic response to it, as well as the rise of “populism”."
Male and female bosses share the same “classically masculine” personality traits
"Men and women in non-leadership roles differed in their personality traits in ways consistent with the existing literature – for instance, women scored higher than men on characteristics associated with being more agreeable, such as being cooperative and people-oriented, while scoring lower on emotional stability and aspects of extraversion. In contrast, the personalities of male and female bosses were far more similar, with many sex-linked differences absent altogether or greatly attenuated (although the women still scored higher on aspects of agreeableness)." See also Women who adopt 'male traits' often see business success, study says

"So you think you’re open-minded…"

Towards the end in a discussion of biases is the bit that I particularly want to point out:

... the last one I’m going to mention is probably the most important. The sophistication effect, in which the most knowledgeable and politically engaged people, “because they possess greater ammunition with which to counterargue incongruent facts, figures, and arguments, will be more susceptible to motivated bias than will unsophisticates”.

Let’s go over that again: the better-informed and cleverer you are, the more vulnerable you are to certain biases, such as motivated scepticism, because you are more able to destroy the arguments that you don’t like, but still feel no particular desire to examine the ones that you do. If you’re a politically well-informed and intelligent Corbynite, it will be amazingly simple to find the examples of Tories using it as a smear, and vice versa.

So it becomes easy to tear down silly arguments by your opponents, and so you become ever more convinced of your own brilliance and their idiocy or malignity.

I don't think in the case of journalism that something like Breitbart is a great alternative, but it seems to me that groupthink exists amongst journalists as, e.g., Nate Silver has argued. I also think that the same applies amongst academics when it comes to a number of politically sensitive subject areas.

Review of Steven Pinker’s Enlightenment Now

Math, Girls and Socialism
"the gender gap in math is smaller in European countries that used to be part of the Soviet bloc, as opposed to the rest of Europe. The lesson is twofold: (1) a large part of the pervasive gender gap in math is due to social stereotypes; (2) institutions can durably modify these stereotypes."

"When a measure becomes a target, it ceases to be a good measure"
