Never hire an A student unless it is to take exams.

The Grade Trap vs. Real Results

The sting in this quote comes from a truth we rarely admit: the skills that get you top grades often don't match the skills that change things in the real world. An A student excels at understanding what someone else has already figured out and reproducing it perfectly. They're great at the known game. But building something new, fixing what's actually broken, or navigating the messy uncertainty of real work requires a different muscle entirely—one that often looks like failure on a report card.

Think about the people who actually innovate or solve problems in your own life. They're rarely the ones who played it perfectly safe. They experimented, took detours, questioned the instructions. Some of their best ideas came from not knowing the "right" way. Meanwhile, perfect students sometimes get paralyzed when there's no rubric, no right answer waiting to be discovered. They've been trained to optimize for being judged, not for being useful.

That said, Taleb's exaggeration matters. You do want smart people. His real point is about what kind of smarts you need: people who think independently, who can tolerate being wrong, who value results over credentials. The unsettling implication is that our most trusted filtering system—academic performance—might actually be selecting for the opposite of what we claim to want.
