Why Your Brain Can't Resist a Sale (It Thinks Winter Is Coming)

"Only 2 left!" A countdown timer. Was $199, now $79. Sale season is here — the October deal days, then Black Friday and the festive sales — and every one of them pushes the same 200,000-year-old buttons. To your caveman brain, a sale looks like a berry bush that's almost empty, with a rival tribe coming over the hill. The scarcity effect (the famous cookie-jar study), fake countdown timers, social proof, anchoring and the crossed-out 'was' price, the power of FREE, the decoy trick, the dopamine thrill of the hunt — and five Grug hacks to shop like the hunter, not the hunted. 📘 FREE Caveman Brain Field Guide (10 ancient brain programs + how to hack them): https://cavemanbrain.gumroad.com/l/ca...
