In 1994, I was sitting in a first-year class at Harvard Business School called Technology and Operations Management. And when I tell you I have never felt more stupid in my life, I am not exaggerating. I couldn't follow what was happening. I wanted to crawl under the desk and disappear. It was humiliating.
Then one day the professor started teaching us Toyota, and how in the early 1930s they invented a deceptively simple algorithm called the 5 Whys. Five sequential questions that got to the root cause of any problem. An idea so elegant it literally revolutionized global manufacturing.
And I had an epiphany.
It wasn't that I was stupider than everyone else in that room. It was that I had never learned the craft of thinking, and many of my colleagues had. Thinking critically isn't a gift you're born with. It's a craft. And like any craft, it can be learned, and improved.
Later, I came across research from Yale establishing that genius and IQ are far less connected than most people assume. The researchers compared it to height: being born tall might give you an advantage on a basketball court, but it doesn't make you a great basketball player. Greatness is built, not inherited.
I started imagining a technology that could teach people to think more deeply, that could scale brilliance the way Toyota scaled quality. Putting Socrates in everyone's pocket. Using the 5 Whys and Socratic method not as classroom exercises, but as the architecture of an entirely new kind of tool.
I've been carrying that idea for thirty years.
The technology wasn't ready. Until now.
