Summary
Luke Hewitt is a research-focused technologist who builds computational tools to help public health and advocacy campaigns optimize impact, blending expertise in RCTs, hierarchical Bayesian models, expert forecasting, and LLM evaluation. With a PhD in AI and Cognitive Science from MIT and a background in mathematical computation from UCL, he has led and co‑led interdisciplinary projects at Stanford, the Mercury Project, and Swayable that translate rigorous experimentation into persuasive messaging strategies. He consults on AI safety and evaluates persuasive capabilities of frontier models for organizations like OpenAI and the UK AI Security Institute, bringing hands-on model testing to policy-relevant questions. As co-founder of the Rhetorical Impact Lab and a member of South Park Commons, he pairs academic depth with startup pragmatism to move research into operational tools for real-world campaigns. An often-overlooked strength is his ability to combine formal causal inference with practical messaging experiments, making complex methods accessible to practitioners.
