Racial differences in mortality are large, persistent and likely caused, at least in part, by racism. While the causal pathways linking racism to mortality are conceptually well defined, empirical evidence to support causal claims related to its effect on health is incomplete. In this study, we provide a unique set of facts about racial disparities […]

On June 18, 2025, Health New Zealand published extensive data (March 2025 quarter) in a two-page spread contained in The Post. I assume this was replicated in other New Zealand newspapers. Included were childhood immunisation rates. At the bottom of the table for full immunisation at 24 months are Northland and Tairawhiti districts (improving trend) followed…

Yesterday, the Supreme Court issued its 6-3 ruling upholding a Tennessee ban on transgender medical treatments for adolescents. The ruling has major implications for pending transgender cases, particularly the concurrence of Justice Amy Coney Barrett rejecting the claim that transgender status qualifies as a group entitled to heightened scrutiny under the Constitution. One of those […]

In the 1960 cohort, American men and women graduated from college at similar rates, and this was true for Whites, Blacks and Hispanics. But in more recent cohorts, women graduate at much higher rates than men. Gaps between race/ethnic groups have also widened. To understand these patterns, we develop a model of individual and family […]

Chris Trotter writes – “Your mission, Mr Hipkins, should you choose to accept it, is to lead Labour to victory in 2026.” Except, as always, the drama of a Mission Impossible movie lies not in the what, but in the how. Of course Chris Hipkins is willing to lead Labour to a win. The real question is […]

For all the gravitas which Dame Marilyn’s involvement has conferred upon PSCPE, it is important not to lose sight of the fact that it represents a deliberate attempt to morally overpower what is now the law of the land. Chris Trotter writes – The People’s Select Committee on Pay Equity (PSCPE) is looking for evidence. […]

Regulations about abortion are often wildly controversial. But what effects to they actually have? Caitlin Myers addresses these issues in “From Roe to Dobbs: 50 Years of Cause and Effect of US State Abortion Regulations” (Annual Review of Public Health 2025, pp. 433-446). As a starting point, consider the years before and after the 1973 US Supreme Court…

The Herald reports: During her Budget presentation, Willis said that pay equity costs in 2020 were initially expected to reach $3.7b but there had since been a “blowout” with costs rising steeply, especially due to Labour’s 2022 decision to fund claims in the “funded sector”. The exact figure isn’t known, but as they have announced […]

The University of Oregon has long faced controversies over the alleged political bias on its campuses, including celebrating the career of a professor who physically attacked pro-life students as a model of activism. It has been criticized for monitoring off-campus speech and unconstitutionally censoring dissenting faculty. Now, Law Professor Ofer Raban is accusing the Law […]

Nature tackles race and eugenics in a torturous and tortuous article

Yes, folks, the science journals are still flaunting their virtue in articles that are similar to a gazillion articles published before. This time (and not the first time), the article is torturous because the assertions are mostly misleading. And it’s tortuous because it weaves back and forth between two themes: eugenics and the assumed beneficial […]

Labour leader Chris Hipkins has joined the chorus of those opposing changes to pay equity legislation. Does this mean he knows what a woman is now? It is easy for opposition parties and their allies to criticise proposed changes but Heather du Plessis-Allan points out the problem with existing legislation: . . . Those pay […]

I’ve written a couple of times about information interventions designed to attract more female students to study economics (see here and here). The results have generally been disappointing. That shouldn’t be too much of a surprise. If it was really simple to get people to change their behaviour with information, then advertising would be far…
