I started reading up on the whole "loneliness pandemic" narrative because this seems like a literature where the age-period-cohort problem may be relevant (or maybe it isn't?). Here's data from Australia (HILDA), average agreement with the statement "I often feel very lonely" (SD of ca. 1.8).>

These openscience.nl grants are wonderful. Lavaan is a stand out in quality and impact. Open software supports so much research in academia and industry, but exists in some unincentivized gray zone. At the same time, so much software is poorly documented and tested. Fix with recognition and support
I've used Lavaan almost every (work)day for 15 years, but this open source labour of love has never received proper institutional support. I'm delighted to be a small part of an 1.5M OpenScienceNL award, led by Jorgensen, to completely revamp and futureproof Lavaan www.openscience.nl/en/news/45-p...
Today I note how, after Florida implemented their #cellphoneban in schools, Florida's national standardized testing scores dropped. We need to work harder to improve schools by improving schools, not by banning technology. www.tallahassee.com/story/opinio...

Youyou Tu's work on anti-malarial compounds that saved millions of lives (w/Nobel+Lasker recognition) wins the low citation/huge impact cell. The original paper has 87 citations as of today: pubmed.ncbi.nlm.nih.gov/11721477/ Hopefully she can get to 100. What for huge citations and moderate impact?

To be honest? Thank god. Because if advertisers can target on personality, this will be what it looks like (from 'Careless People')

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. doi.org/10.1007/s112... 🧵👇 (1/5)
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.
