does non-falsifiable imply not true?

This post is a longer-form discussion following this Twitter thread. The thread began with Steve Vaisey expressing interest in how gender scholars would respond to this article, which apparently shows that women in more-gender-egalitarian societies have personality profiles more different from men than do women in less-gender-egalitarian societies. It then presents evolutionary psychology as one way that people might interpret that finding, implying that gender-based personality differences might be “natural,” not socially constructed, since they are more different when society “gets in the way” less, i.e., when society is freer.

I have still not read the article, but only the abstract, so my comments are about the discussion that followed, not about the quality or interpretation within the study.

blame it on pomo

Postmodernism is the first intellectual movement to acknowledge its own historical partiality. From that spring many of its faults and virtues, not to mention its caricatures. Because for a movement in some ways so arrogant — so insistent on its own epistemic correctness — to insist as well that it was always already partial evokes the kind of unease that many pundits (and social and natural scientists) feel when discussing postmodernism. Unfortunately, it also evokes the caricatures (not to say reaction-formations) that are common among those same pundits and scholars. Continue reading “blame it on pomo”

newfield, the great mistake

Christopher Newfield’s The Great Mistake: How We Wrecked Public Universities and How We Can Fix Them is a great book – you should buy it, read it, teach it, and recommend it to your friends. In an increasingly crowded field of books about the ills of contemporary higher education (many of which I also like), this one is particularly strong for its insistence on a systemic, political-economic analysis and its refusal to offer overly simplistic answers. In what follows I offer a discussion of the book’s argument and successes along with two critiques of elements that I think weaken its claims.

the voter fraud investigation: an opportunity for science?

President Trump’s announcement that he will launch an investigation of voter fraud is interesting for many reasons. Some of these have been well-documented, such as that he continues to believe massive voter fraud caused his popular-vote loss, and that the main “evidence” cited for such fraud has been thoroughly debunked.

In the context of other recent announcements, it’s also interesting because it may offer an opening for demonstrating the value of evidence-based, systematic inquiry: that is, of science as a basis for policy.

cost-cutting in higher ed

In the Washington Post earlier this week, Steve Pearlstein published a piece promoting four things universities should do to cut costs:

  1. Cap administrative costs
  2. Operate year round, five days a week
  3. More teaching, less (mediocre) research
  4. Cheaper, better general education

The next day, Daniel Drezner responded with four things columnists should do before writing about universities.

  1. Define what you mean by “universities.”
  2. Don’t exaggerate the problems that actually exist.
  3. Don’t rely on outdated data.
  4. Be honest that you’re using higher ed reform as an implicit industrial policy.

are all human traits heritable?

A new article by Polderman et al. in Nature Genetics, nicely summed up by Jeremy:

is a meta-analysis of essentially every twin-based study of heritability of any trait between 1958 and 2012. The top-line coverage, encouraged by the authors’ press release, is:

One of the great tussles of science – whether our health is governed by nature or nurture – has been settled, and it is effectively a draw.

This is based on the fact that, across 17,804 traits in 28 “general trait domains,” the overall mean heritability was 49%. That prompted me to write:

Read on for why I think that, what value there is in the below-the-fold part of the article, and why I think this kind of work is in desperate need of an injection of theory. Continue reading “are all human traits heritable?”

prestige trumps quality in faculty hiring? not so fast

This article (Clauset, Arbesman, and Larremore. “Systematic inequality and hierarchy in faculty hiring networks”) has been making the rounds lately. The article uses a network method to extract prestige rankings from the set of graduate degrees and faculty hires. It shows “that faculty hiring follows a common and steeply hierarchical structure that reflects profound social inequality.”

Blog posts, tweets, and stories about the article (e.g., this one from the Monkey Cage) have mostly picked up on the idea that the fact that prestigious departments generally hire Ph.D.s from other prestigious departments must mean that “academia is not a meritocracy.” While I would certainly not claim that academia is a meritocracy, I don’t think the Clauset et al. paper demonstrates that.
