Alec Litowitz joined a hedge fund with $100 million in assets and six employees.
He had never made a trade in his life.
That fund was Citadel, in its earliest days, and Alec became one of its founding partners alongside Ken Griffin — eventually running its global equities business. He later left to start his own firm, Magnetar Capital, now one of the largest alternative asset managers in the world.
Somewhere across those three decades, Alec noticed something uncomfortable: the smartest, most experienced people in the room are often the last ones to realize the world has changed. Not because they’re not smart. Because they’re the most attached to having already been right.
His new book, The Adaptability Quotient, argues that raw intelligence and experience — IQ and EQ — aren’t enough anymore. What matters now is a third thing: how fast you notice your mental model is wrong, and how willing you are to let it go.
We get into why Blockbuster’s downfall wasn’t really about one bad decision, how to tell whether a shift in your industry is temporary or permanent, why AI might make judgment scarcer even as it makes knowledge abundant, and why Alec says a “diversified” portfolio can secretly be one big bet in disguise.

Key Takeaways
- The Highest-IQ People Are Often the Last to Notice Reality Changed: Alec’s core argument is that intelligence and experience can work against you — the more successful your existing mental model has been, the harder it is to notice, and admit, that it’s stopped working.
- “AQ” Isn’t Grit or Resilience Rebranded: Adaptability quotient, as Alec defines it, isn’t about pushing through difficulty — it’s about how quickly you update your thinking when the evidence says you’re wrong.
- AI Doesn’t Just Hand You a New Tool — It Changes What’s Scarce: Once knowledge becomes abundant and cheap (which AI is doing fast), Alec argues that judgment and agency — not information — become the resource that’s actually in short supply.
- Blockbuster’s Real Mistake Wasn’t a Decision — It Was Never Testing One: Alec’s take on the Blockbuster/Netflix story isn’t that Blockbuster chose wrong. It’s that they never ran the small, cheap experiments that would have shown them their model was already broken.
- A “Diversified” Portfolio Can Secretly Be One Concentrated Bet: Alec points out that several of the largest stocks driving the S&P 500 right now are all correlated to the same underlying theme — meaning a portfolio that looks spread out on paper can really be one large, undiversified wager.
- He Chose to Be a Less Maximized Investor So He Could Be a Better Father: Alec is candid that he could have been “more successful” by conventional measures if he’d spent less time with his kids — and that he doesn’t consider that trade worth it.
