I’ve done this and I can attest that it works, but I never knew it had a name.
Body-doubling is simply having another person in the room with you, working quietly alongside you. They can work on something similar, or something completely different.
A look at the trend towards larger and larger font sizes for body copy on the web, culminating with Resilient Web Design.
There are some good arguments here for the upper limit on the font size there being too high, so I’ve adjusted it slightly. Now on large screens, the body copy on Resilient Web Design is 32px (2 times 1em), down from 40px (2.5 times 1em).
Robin Sloan smushes the video game Fortnite Battle Royale together with Liu Cixin’s Three Body Problem trilogy and produces a perfect example of game theory, cooperation, and the prisoner’s dilemma.
Based on my experiments in the laboratory of Fortnite, I think Liu Cixin is wrong. Or at least, he’s not entirely right. Fortnite is more Dark Forest theory than not, and maybe that’s true of the universe, too. But sometimes, we have a lever against the vise of game theory, and in this case, it is a single bit of communication. I mean “bit” in the programmer’s sense: a flag with a designated meaning. Nothing more. My heart emote didn’t make Fortnite cuddly and collaborative, but it did allow me to communicate: “Hold up. Let’s do this a different way.”
We are on our way to a bright Maneki Neko future.
