AMERICAN DISRUPTION

YOU'RE PROBABLY DOING USER RESEARCH WRONG

Product teams waste resources asking the wrong questions. At a focus group in Venice, users claimed they'd never use Tinder again—yet moments later, nearly everyone admitted meeting someone through the app that year. This contradiction reveals three types of research questions with dramatically different reliability: "What did you do?" questions about past behavior yield trustworthy insights because people accurately remember their actions. "What are you doing?" questions capture unfiltered reactions in real-time, revealing genuine confusion or delight without mental editing. "What would you do?" questions about future behavior are the least reliable, since human imagination is flawed and influenced by virtue signaling, yet most common.

YOUR BELIEFS ARE YOUR STRATEGY

Every founder should write a manifesto. It helps you get clear about what you're building and why it matters. A good manifesto starts with your customers. What are they trying to do? What stands in their way? Then explain how your approach is different. Why did you build things this way? Most importantly, write down what you believe. These beliefs drive your choices about features, markets, and everything else. They're your real strategy. When you finish writing, you'll see you weren't just making words. You were making choices that help you stand out when talking to customers or investors.
