(uploaded February 19, 2026) presented by Tamsen Webster, a reasoning researcher and founder of the Message Design Institute. The speaker explains a framework distinguishing two kinds of ideas—concept ideas (which name or define phenomena) and action ideas (claims that link a concept to a desired outcome)—and outlines the three beliefs people need before taking action (possible in principle, possible in practice, and worth it). The talk includes examples (psychological safety, Adam Grant’s giver/taker distinction, frameworks like EOS), guidance on turning concepts into supported claims, and a call-to-action to join the Message Design Institute newsletter, office hours, or a Fundamentals of Message Design webinar.
