Meeting a romantic partner via being set up by mutual friends is a network phenomenon and a habit that is very old, as discussed in our 2009 book, Connected (www.amazon.com/Connected-Su...)
Your single friends are dying for you to set them up
Tired of dating apps, some singles long for their friends to get into amateur matchmaking.

The official government account for DHS appears to be run by far-right trolls deliberately trying to provoke a response by using a term openly associated with ethnic cleansing. They will attack anyone who points this out and express faux outrage at the suggestion. They know what they are doing.

Every academic career is built on rejection, but we don’t show it.
CVs list publications, grants & awards, not rejected manuscripts, unfunded proposals, or failures.

Cursing is rarely a symbol of low class. It's often a mark of high authenticity.
Evidence: Swearing predicts higher rates of honesty and integrity. It signals a willingness to prize candor over courtesy.
A little profanity can show that you're being real and you do give a damn.

Yes. Some people have less consistent preferences. ;-)
In related work, in 2008, we studied whether a man has an increased risk of death when his ex-wife dies, comparable to when his current wife dies (as a test of homogamy) in a sample of one million Americans.
No, the death of an ex-wife has no discernible effect.

Wives and ex-wives: A new test for homogamy bias in the widowhood effect - Demography
Increased mortality following the death of a spouse (the “widowhood effect”) may be due to (1) causation, (2) bias from spousal similarity (homogamy), or (3) bias from shared environmental exposures. This article proposes new tests for bias in the widowhood effect by examining husbands, wives, and ex-wives in a longitudinal sample of over 1 million elderly Americans. If the death of an ex-wife has no causal effect on the mortality of her husband, then an observed association between the mortality of an ex-wife and her husband may indicate bias, while the absence of an effect of an ex-wife’s death on her husband’s mortality would discount the possibility of homogamy bias (and also of one type of shared-exposure bias). Results from three empirical tests provide strong evidence for an effect of a current wife’s death on her husband’s mortality yet no statistically signifi cant evidence for an effect of an ex-wife’s death on her husband’s mortality. These results strengthen the causal interpretation of the widowhood effect by suggesting that the widowhood effect is not due to homogamy bias to any substantial degree.

Do people have a “type” when it comes to their romantic partners’ personalities? A 2019 analysis of 332 Germans (159 men, 173 women) who had self-reports of personality available from two different partners during a 9-y longitudinal study indicates this is the case.

The video captures the relocation due to the air-raid in Kyiv like an old-fashioned movie intermission, and the energy of the students was palpable. It was an incredible experience, and I was so impressed with everything I saw at KSE.
I spoke at the Kyiv School of Economics last month, on "Social Artificial Intelligence" (www.youtube.com/watch?v=JtaX...) & "Social Network Interventions" (www.youtube.com/watch?v=vCnZ...).
The latter started in a big airy room but, half way in, an air raid forced relocation to Soviet bomb shelter.

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.
