The new phrenology?

Ubiquitous facial recognition technology can expose individuals’ political orientation, as faces of liberals and conservatives consistently differ. A facial recognition algorithm was applied to naturalistic images of 1,085,795 individuals to predict their political orientation by comparing their similarity to faces of liberal and conservative others. Political orientation was correctly classified in 72% of liberal–conservative face […]

Causes of the sex drought

Among young men, declines in drinking frequency, an increase in computer gaming, and the growing percentage who coreside with their parents all contribute significantly to the decline in casual sex. The authors find no evidence that trends in young adults’ economic circumstances, internet use, or television watching explain the recent decline in casual sexual activity. […]

Higher education sentences to ponder

We find that the WTP [willingness to pay] for in-person instruction (relative to a remote format) represents around 4.2% of the average annual net cost of attending university, while the WTP for on-campus social activities is 8.1% of the average annual net costs. We also find large heterogeneity in WTP, which varies systematically across socioeconomic […]

Why are atheists so unpopular?

Building on theory about the cultural, (de)motivational, and cognitive antecedents of disbelief, the present research investigated whether there are reliable similarities as well […]

Cool, green Britannia

Over the summer of 2020, as coronavirus cases fell and life in Britain felt briefly normal, something very abnormal was happening to the country’s electricity supply. No coal was burned to generate any portion of it for a period of more than two months, something that had not happened since 1882. Britain’s four remaining coal-burning […]

In mid-April, while he was living with his parents in Santa Clara, Calif., Gu spent a week building his own Covid death predictor and a website to display the morbid information.

Ba et al.overcame previous data constraints and found that Hispanic and Black officers make far fewer stops and arrests and use force less than white officers, especially against Black […]

What are the most important statistical ideas of the past 50 years?

We argue that the most important statistical ideas of the past half century are: counterfactual causal inference, bootstrapping and simulation-based inference, overparameterized models and regularization, multilevel models, generic computation algorithms, adaptive decision analysis, robust inference, and exploratory data analysis. We discuss common features of these ideas, how they relate to modern computing and big data, […]

Monopsony it ain’t, rather output loss

We use highly consistent national-coverage price and wage data to provide evidence on wage increases, labor-saving technology introduction, and price pass-through by a large low-wage employer facing minimum wage hikes. Based on 2016-2020 hourly wage rates of McDonald’s Basic Crew and prices of the Big Mac sandwich collected simultaneously from almost all US McDonald’s restaurants, […]
