Academia's Missing Men. Lawrence Krauss argues that in their efforts to promote “diversity”, American universities are increasingly sidelining men. By way of example, he notes that six of the eight Ivy League colleges (Harvard, Brown, Penn, Cornell, Dartmouth, and Columbia) now have female presidents, as do Berkeley and MIT.

Zero-Sum Thinking and the Roots of U.S. Political Divides. Sahil Chinoy and colleagues explore the correlates of zero-sum thinking in the US. They find that a zero-sum mindset is more common among young people, blacks and Hispanics, and those with a lower income. They also find that zero-sum thinking is strongly associated with support for redistribution, support for affirmative action and opposition to immigration.

Contrary to the expectation of many psychologists, he shows that there is a robust positive association between the two variables whose strength increases with the complexity of the reaction stimulus.

Reaction time correlates more strongly with intelligence when complexity of the reaction stimulus is higher (A corresponds to a sample of ninth graders; B to a sample of college students).
