obviously it was pea-hacking

No-one has ever been able to replicate Gregor Mendel's observations of pea plants. They're a little "too perfect", lacking even random statistical noise that would have been expected from small sample sizes.

The big question: was it scientific fraud?

regor MendelGregor Mendel (1822-1884). Illustration of the Austrian botanist and founder of genetics Gregor Mendel, with pea plants. During the period 1856-63 Mendel, the abbot of an abbey in Brno, Austria, bred almost 30,000 pea plants in his monastery garden. By crossing strains of pea he demonstrated that hereditary characteristics were inherited from the parent plants. His work was ignored until 16 years after his death, but he is now considered the founder of genetics. His results revealed the statistical laws of heredity, and he postulated the existence of a unit of heredity that is now called the gene.

It was a nice surprise to hear that our recent article could be published open access for free, thanks to an agreement w/ CRKN! In 745 couples, willpower beliefs were associated with relationship satisfaction & social support, but belief similarity didn't matter. journals.sagepub.com/doi/10.1177/...

Happy (American) Thanksgiving! Thanksgiving dinners with people from opposite-partisan-voting precincts are 30-50 minutes shorter than dinners with just same-party dinners, finds Chen & Rohla using smartphone-location data.

A classic piece of Thanksgiving research!

Image description The effect of partisanship and political advertising on close family ties M. Keith Chen and Ryne Rohla Image description Fig. 1 Sampling and imputation validation. (A) Results of the 2016 U.S. presidential election by precinct (excludes unpopulated census blocks). (B) Home locations of smartphone users in the 2016 sample. (C) Correlation between actual two-party vote share by state and the District of Columbia (DC) (x axis) and predicted vote share (y axis) using each smartphone user’s home precinct. Nationally, this predicts a 0.516 Clinton vote share, compared to an actual vote share of 0.511. Highlighted are the two most Democratic-leaning states (California and Massachusetts) and two most Republican-leaning states (Wyoming and West Virginia), as well as the states with the largest prediction error.
