The quoted graph showing final and midterm scores diverging, with a shoddy fake regression line scribbled through. Surely a visual correlation means good measurement?

A photo of the Japanese national breakfast: toast with butter, salad, and a boiled egg. Also some yogurt on the side and sweet red beans on the toast. The boiled egg has googly eyes and looks nervous about what the future holds.

lemonsharks My ancestors, watching me dump an entire stick of cinnamon, two cloves, an allspice berry, and a generous grating of nutmeg into my tea, sweetened with white sugar and loaded with cream, while l sit in my clean warm house surrounded by books, 25+ outfits for different occasions, and 6 pairs of shoes, in a building heated so well have the windows open in mid-autumn: Our daughter prospers, We are proud of her, She has never labored in a field but knows riches we could not have imagined.

A snippet from the XKCD comic "Compiling" (https://xkcd.com/303/). Two stick figures are having an office chair sword fight. A voice from the other room calls out "Hey! Get back to work!" to which one of the fighters replies "CLAUDE!" The other voice replies "Oh. Carry on."
Cartoon of a bearded man protesting probabilism. He is shaking an impotent fist and wearing a shirt that reads "probabilism", crossed out with a red circle and slash. He looks only moderately unhappy, as if his heart isn't in it, he doesn't know what probabilism is, and he's not sure if he's going to get paid for showing up this time

Cebrian analyzed his (and other) crowdsourcing contests with the help of Victor Naroditskiy, a game theory expert at the University of Southampton. The results shocked him. "The expected outcome is for everyone to attack, regardless of how difficult an attack is." says Cebrian. "It is actually rational for the crowd to be malicious, especially in a competition environment. And I can't think of any engineering or game theoretic or economic incentive to stop it"

XKCD 793 [Cueball stands at a blackboard covered in diagrams, an open laptop and scattered paper at his feet. His fists are balled in anger and there is a little angry squiggle over his head. A Cueball-like physicist stands behind him, arms out in a shrug.] Physicist: You're trying to predict the behavior of <complicated system>? Just model it as a <simple object>, and then add some secondary terms to account for <complications I just thought of>. Physicist: Easy, right? Physicist: So, why does <your field> need a whole journal, anyway? [Caption below the panel:] Liberal-arts majors may be annoying sometimes, but there's nothing more obnoxious than a physicist first encountering a new subject.

When you’re scared you get tunnel vision. If everything’s malleable, potential or imaginary future harms start to seem equivalent to concrete harm, even violence, being inflicted today. You start to equate things that aren’t equal. And you lose sight of your power. This, I would argue, is more likely to lead to fatalism and surrender than Coates’s approach.
I speak of course now only about the Disney corporation, and not about the heroic Disney Adults whose combined capitalist ferver has restored Jimmy Kimmel to the air as of today. Also, let us all hope this is the weirdest footnote I will ever have to write.
