“Grip strength, an index of upper body strength, is highly sexually dimorphic: 90% of men are stronger than 90% of women. Could this help explain sex differences in emotional responses to adversity?” https://threadreaderapp.com/thread/1496488028956725251.html
Sex differences in fear is mediated by that in physical strength https://threadreaderapp.com/thread/1524442032466325504.html
Substantial but Misunderstood Human Sexual Dimorphism..."sexual dimorphism in lean mass, muscle mass, and strength are largely due to sexual selection arising from a long history of aggressive male mating competition" https://frontiersin.org/articles/10.3389/fpsyg.2022.859931/
"An estimated 38% of traffic deaths involving women on this day were attributable to Friday the 13th itself. … a dangerous day for women, largely because of anxiety from superstition." https://pubmed.ncbi.nlm.nih.gov/12450968/

A novel RL algorithm: “The reward bases algorithm enables instant (zero-shot) generalization of value functions (and thus behaviour) when the reward function changes using only standard temporal difference learning. We obtain equivalent performance to successor representations with less memory cost.” https://www.biorxiv.org/content/10.1101/2022.04.14.488361v1.abstract
“We introduce 𝚃-𝙵𝚎𝚠 and (𝙸𝙰)³, a few-shot learning recipe that outperforms in-context learning at dramatically lower costs and gets super-human results on the RAFT benchmark for the first time.” https://arxiv.org/abs/2205.05638

The probability of an alien invasion and simulation shutdown increases as the distance to the invention of artificial general intelligence decreases. Allowing things to continue after that point becomes prohibitively expensive very quickly.
