Word of caution: anyone who calls those thugs "fascists" is guilty of inciting violence. (If you need a dictionary to comprehend this, try Enid Blyton's Topsy-Turvy World. You can find it at the top of the Magic Faraway Tree.)

A post-doctoral opportunity in Germany (must be in the state of Lower Saxony). Open to applicants from overseas. (To clarify: I have nothing to do with this and am just forwarding the call, I don't have further information). The Volkswagen Foundation is a public agency that has no connection to VW.

Core to our approach is that people's personal risk differs considerably -- a senior white male professor with tenure is more secure than a visiting scholar from the majority world, for example. Hence we structure possible actions around a personal risk assessment: 7/12

Finally, we considered three different indices of congressional productivity that political scientists have developed as performance indicators. As shown below, all three are positively associated with the EMI score:

The pattern for polarization is similar and is shown in this figure. Unlike the inequality data, in this instance the association involves the same session of Congress for both measures – polarization today is associated with today’s balance between evidence and intuition.

For all three indicators we found that a decline in the EMI score led to worse outcomes.
The figure below shows the association between EMI (on the horizontal axis) and income inequality (vertical). Inequality here is represented by the share of income available to the top 1%.

The figure below shows the temporal trend in our EMI score, both overall (top) and broken down by party (bottom). Positive EMI means evidence is favoured over intuition and vice versa for negative EMI scores.
