Challenge Your Mindset Modes: Stop Preaching, Prosecuting, and Politicking—Start Thinking Like a Scientist

When resolving a disagreement, most people slip unconsciously into one of three roles: preacher (defending sacred beliefs), prosecutor (seeking to prove others wrong), or politician (aiming to win approval). Each mode feels comfortable, even virtuous—after all, who doesn’t want to be right, correct others, or get support? But these modes can turn our minds into fortresses, locked against new information.

Instead, the scientist mindset treats every belief more like a theory than a law. At a kitchen table or in a boardroom, adopting a scientist’s approach means stating opinions as testable guesses, seeking out evidence that runs counter to them, and tracking what actually works or surprises.

Foundational research suggests that people who systematically test their beliefs—rather than clinging to identity-based positions—are far better at adapting to change, solving new problems, and building trust within diverse teams. This mindset isn’t about giving up conviction, but about holding it lightly, ready to update when the world changes.

Think back to your last heated discussion—did you find yourself preaching, prosecuting, or politicking? This week, challenge yourself to name which one pops up when a disagreement arises. Instead of digging in, force yourself to write down: what evidence could actually change my view here? Treat your opinions as living, breathing hypotheses, and push yourself to seek out an article or talk with someone who you know holds the opposite position. When you catch yourself defaulting to certainty, deliberately step into scientist mode and even say out loud, 'Let’s treat this like an experiment.' Notice how conversations change—and see what you learn about yourself. Try it at your next family dinner or team meeting.
