FLASHCARDS! You Are a Game Theorist!

What if the negotiation strategies, workplace rhythms, and relationship instincts you've relied on your whole life already had names in mathematics? In today's FLASHCARDS! episode of Math! Science! History!, I break down three foundational concepts from game theory: dominant strategy, tit for tat, and Nash equilibrium, and connect each one to the everyday decisions, compromises, and unspoken social contracts you navigate all the time. Whether you're a math enthusiast or someone who swore they "weren't a math person," this episode reveals that you've been doing game theory your entire life without even knowing it.

🃏 In This Episode, You Will Learn:

• What a dominant strategy is and how to recognize when you're already using one, from sending that follow-up email to ordering your favorite dish at a restaurant.
• The fascinating history of tit for tat, the surprisingly simple strategy that beat out complex algorithms in Robert Axelrod's famous 1980s tournament, and how it mirrors the unspoken rules of your closest relationships.
• How a Nash equilibrium shows up in everyday conflict, and why the moment you and someone else silently agree to "stop pushing" is actually a mathematically stable outcome.
