In Malcolm Gladwell’s Blink, we’re introduced to a powerful idea: sometimes, our first instincts—those snap judgments we make in a fraction of a second—are not only valid, but deeply insightful. He calls this “thin-slicing”: the ability of our unconscious mind to filter data and deliver a verdict before we’ve had time to consciously analyze the situation.
I believe Blink gets something fundamentally right. Intuition matters—especially when it’s shaped by years of experience, pattern recognition, and tough calls. But intuition alone doesn’t guarantee wisdom.
The Three-Day Rule: A Wisdom Buffer for CEOs
That’s where Glen Mayfield comes in.
Glen was the founding partner of River Cities Capital, and a mentor I had the privilege to learn from early in my career. Glen had this saying—one that many younger, eager operators (myself included at the time) initially found frustrating:
“If you need an answer today, it’s no. Come back in three days.”
At first glance, it seemed like a stall. But over time, I saw the brilliance behind what I now call the Three-Day Rule.
Why the Three-Day Rule Works: A Snapshot of Leadership Insights
Here’s what Glen was really doing—he’d make a snap judgment (that gut reaction Blink celebrates), and then give it time to breathe. He trusted his instincts, but allowed his unconscious mind to keep processing. If it still felt right three days later, he moved. If it didn’t, he’d adjusted. It was intuition with a buffer. Wisdom in motion.
The Cost of Indecision: How the Three-Day Rule Prevents Analysis Paralysis
And here’s why this matters now more than ever: the cost of indecision is real.
I’ve worked with two ends of the spectrum. Founding CEOs of lifestyle businesses often take too long to act. They stew. They revisit. They avoid. On the other end, PE-backed CEOs—especially those new to operating roles—can over-index on data. They wait for perfect clarity in imperfect environments. Paralysis by analysis sets in.
Balancing Intuition and Data: The CEO’s Guide to Smart Decision-Making
Great CEOs know better. They live in the tension between speed and certainty. They trust their instincts, use data to sharpen rather than delay, and give big decisions room to breathe without letting them go stale.
