"celebrities are like dealing with like anorexia nervosa levels of like real risk to self-harm and all this stuff." (said at 0:21:40)
No published record matching the claim that celebrities face rates of mental health issues or self-harm risks comparable to those seen in anorexia nervosa was located; this does not prove the claim false.
"The update to that study is it's a curvi-linear graph where it's a really steep ascent of happiness, and then north of 75 to 100k the curve still goes up, but at a much shallower rate. And if you measure it individual by individual, it actually is huge variance." (said at 0:35:43)
Updated research by Killingsworth (2021) and an adversarial collaboration by Killingsworth, Kahneman, and Mellers (2023) re-evaluated the classic Kahneman & Deaton (2010) finding of a happiness plateau at $75,000. On an absolute income scale, the relationship between income and well-being is curvilinear (linear with log-transformed income), rising steeply at lower income levels and continuing to increase at higher incomes with diminishing absolute dollar returns. Furthermore, the 2023 collaboration revealed substantial heterogeneity across individuals: for the least happy 20%, well-being plateaus above approximately $100,000, whereas for the majority of happier individuals, well-being continues to rise steadily or even accelerates past that threshold.
"Drawing on 1,725,994 experience-sampling reports from 33,391 employed US adults, the present results show that both experienced and evaluative well-being increased linearly with log(income), with an equally steep slope for higher earners as for lower earners. There was no evidence for an experienced well-being plateau above $75,000/y, contrary to some influential past research." (abstract, results, passage verified)pubmedfull study (doi)
"A reanalysis of Killingsworth's experienced sampling data confirmed the flattening pattern only for the least happy people. Happiness increases steadily with log(income) among happier people, and even accelerates in the happiest group. Complementary nonlinearities contribute to the overall linear-log relationship."
