🚨 New preprint! Our work on machine learning approach to facial emotion detection in political speeches in on ArXiv.
https://arxiv.org/abs/2304.09914
We processed 77 hours of video and found that populist leaders express negative emotions more often than their non-populist counterparts.
Populist rhetoric employed on online media is characterized as deeply impassioned and often imbued with strong emotions. The aim of this paper is to empirically investigate the differences in affective nonverbal communication of political leaders. We use a deep-learning approach to process a sample of 220 YouTube videos of political leaders from 15 different countries, analyze their facial expressions of emotion and then examine differences in average emotion scores representing the relative presence of 6 emotional states (anger, disgust, fear, happiness, sadness, and surprise) and a neutral expression for each frame of the YouTube video. Based on a sample of manually coded images, we find that this deep-learning approach has 53-60\% agreement with human labels. We observe statistically significant differences in the average score of negative emotions between groups of leaders with varying degrees of populist rhetoric.
Check out the graph below, posted yesterday by Prof. Eliot Jacobson (@EliotJacobson) at Xitter.
What you see there is daily standard deviations of Antarctic sea ice extent for every day from 1989 to 2023, based on the 1991-2020 mean. Each blue line represents the SDs over a full year. Lighter is more recent. 2023 is in red.
Sea ice extent is now 6.4 (‼️) standard deviations below the 1991-2020 mean. That's far beyond any expectations, leaving scientists baffled, not to mention alarmed.

Note that the red line on the graph is not showing the current actual extent of sea ice, but rather deviation from the norm. Ice extent is increasing right now around Antarctica, because it's mid-winter. That means it's peak freeze season, except the ice is not growing anywhere near as fast as it should.

Antarctic sea ice has usually been able to recover in winter. But this time it's different, with levels taking a sharp downward turn at a time of year when sea ice usually forms reliably — and experts are worried.
