You should play games all the time, and that way you'll be prepared for emergencies.
Casual practices for are fine for addressing casual situations, but when a significant issue arises — one requiring deliberation and with significant priorities on the line — your casual practices will be insufficient. You will fail, and you will hurt people.
When we're deciding what restaurant to visit, there's no real way to lose: it's a date night, it's a family night, it's a night out! Ramen, spaghetti or udon, you can't fail.
That's what makes it a perfect opportunity to try co-cognition in the form of a game.
Write your options down. Hold a Rock Paper Scissors election. Roll some dice — even deliberate randomness is a higher-order form of collaboration than the familiar "friendly debate". When the stakes are low you have a chance to practice something that becomes difficult in times of tension: intelligence.
Casual conversation is rife with injustice, imbalance and bias. It's no way to run aa country. It's no way to run a business. It's no way to run a household.
Practice process. Become reflexively intelligent.
