Ever caught yourself defending a dumb idea just to look smart?

That's your ego controlling your brain. Cognitive biases and ego team up to screw your decisions daily.

Picture this: confirmation bias has you cherry-picking facts that stroke your self-image, while ego whispers you're too smart for mistakes. Spot the traps like Dunning-Kruger (overestimating skill) or sunk cost fallacy (throwing good money after bad).

Takehomes:

Point at one bias daily: "Am I ignoring counter-evidence like a muscly Irishman blocking the door?"
Test decisions: Can you drop it on your foot? If abstract, make it concrete now.
Audit ego weekly: List three "wins" that were actually luck—kill the illusion.
