The GSS asked the same people about their childhood income rank three different times. 56% changed their answer, even though what was trying to be measured couldn’t change! We dig into this in a new article at @socialindicators.bsky.social.

Growing up Different(ly than Last Time We Asked): Social Status and Changing Reports of Childhood Income Rank - Social Indicators Research
How we remember our past can be shaped by the realities of our present. This study examines how changes to present circumstances influence retrospective reports of family income rank at age 16. While retrospective survey data can be used to assess the long-term effects of childhood conditions, present-day circumstances may “anchor” memories, causing shifts in how individuals recall and report past experiences. Using panel data from the 2006–2014 General Social Surveys (8,602 observations from 2,883 individuals in the United States), we analyze how changes in objective and subjective indicators of current social status—income, financial satisfaction, and perceived income relative to others—are associated with changes in reports of childhood income rank, and how this varies by sex and race/ethnicity. Fixed-effects models reveal no significant association between changes in income and in childhood income rank. However, changes in subjective measures of social status show contrasting effects, as increases in current financial satisfaction are associated with decreases in childhood income rank, but increases in current perceived relative income are associated with increases in childhood income rank. We argue these opposing effects follow from theories of anchoring in recall bias. We further find these effects are stronger among males but are consistent across racial/ethnic groups. This demographic heterogeneity suggests that recall bias is not evenly distributed across the population and has important implications for how different groups perceive their own pasts. Our findings further highlight the malleability of retrospective perceptions and their sensitivity to current social conditions, offering methodological insights into survey reliability and recall bias.

oooh new version of Positron just released and it has (1) github copilot chat and (2) automatic {dplyr} code generation based on filtering/sorting/etc that you do in the data viewer #rstats

A study in Nature Mental Health uses data from the Adolescent Brain Cognitive Development cohort study to evaluate the relationship between state-level income inequality, brain structure and function, and mental health in young people. go.nature.com/4872wyh 🧪
This is figure 3, which shows neural mediators of the link between income inequality and mental health problems 18 months later.

Lots of good suggestions here already but just jumping in
to add that your neighbor always has the option of joining a coworking space/working from a coffeeshop or library! Just throwing it out there that they have options on their end so hopefully you don’t feel too responsible.

✨✨ New paper out in JPSP! ✨✨

Despite rich theory on links between temperament and personality, they're rarely studied together. This has left major unaddressed questions.

We tackled these questions by looking at how temperament and personality develop together from ages 10-26.
