Belonging to something before it disappears
the dark move
Manufactured urgency: a countdown that resets, 'only 3 spots,' a cart that closes at midnight and reopens tomorrow.
why it works · Loss aversion. Your brain treats a possible loss as more real than an equal gain, so it skips the slow thinking.
the bright move
