What is “cognitive atrophy” and why should a leader care?

Stop making your own hard calls for two years and see what’s left of your judgment in year three. I’ve watched it happen to people far smarter than me <••> sharp operators who used to argue every assumption in a room, who slowly stopped doing that once a model could summarize the options for them. It doesn’t feel like loss while it’s happening, which is exactly what makes it dangerous. By the time you notice the muscle is gone, you’re already relying on it in a crisis.
