Previous research focused on popular US Supreme Court rulings expanding rights; however, less is known about rulings running against prevailing public opinion and restricting rights. We examine the impact of the Dobbs v. Jackson Women's Health Organization opinion, which overturned Roe v.

Missing data in experiments: Challenges and solutions.

Missing data is a common feature of experimental datasets. Standard methods used by psychology researchers to handle missingness rely on unrealistic assumptions, invalidate random assignment procedures, and bias estimates of effect sizes. We describe different classes of missing data typically encountered in experimental datasets, and we discuss how each of them impacts researchers' causal inferences.

Prejudice Reduction: Progress and Challenges.

The past decade has seen rapid growth in research that evaluates methods for reducing prejudice. This essay reviews 418 experiments reported in 309 manuscripts from 2007 to 2019 to assess which approaches work best and why. Our quantitative assessment uses meta-analysis to estimate average effects.

Do young rhesus macaques know what others see?: A comparative developmental perspective.

Humans undergo robust ontogenetic shifts in the theory of mind capabilities. Are these developmental changes unique to human development or are they shared with other closely related non-human species? To explore this issue, we tested the development of the theory of mind capacities in a population of 236 infant and juvenile rhesus macaques (Macaca mulatta). Using a looking-time method, we examined what developing monkeys know about others' perceptions.
