Entrainment, a term that originated in biology and then spread to the social sciences, refers to the alignment of an organism’s physiology or behavior with a cycle; the most familiar example would be our circadian rhythm.

Something like entrainment seems to be at work in our relationship to Twitter and other forms of social media. The rate of updates and notifications provides a powerful zeitgeber — one that can even override our circadian rhythm, as any nighttime scroller knows.
