> your reactions to content

do you actually "react" to content? Like chuckle or make any other facial expressions? I just scroll and scroll and scroll with a neutral expression.

Yes. Have you ever used one of those face swap filters that turns you into a funny character that mimics your facial expressions?

Well, how does it know?

A mirth-filled squint of the eyes, dilation of pupils at something unexpected, a tightening of the mouth signalling ennui, the movements that accompany a brief nasal exhalation at something on the nose to your taste in humor... all add to something.

You're not as implacable as you think.
