Behavioral science & say-do gap

Overview

Consumers aren't lying — they genuinely don't know what they'll do. That shared insight anchors these conversations, which examine one of research's most persistent puzzles: the gap between stated intent and revealed behavior. Our guests approach it from two directions. Methodologists argue that surveys, by design, capture aspiration rather than action, and that only real-stakes behavioral tests — live experiments, shop-alongs, and buying-driver studies — can answer the questions practitioners actually need answered. Behavioral scientists, meanwhile, locate the gap not in measurement but in the architecture of choice itself: preference is dynamic, context-shaped, and susceptible to small environmental interventions that move behavior without shifting attitudes. The editorial center of gravity is a reframe — the say-do gap as a structural feature of human decision-making that, read correctly, points toward category disruption rather than research failure.

From the corpus

  • In a live experiment for a food-delivery brand, the value proposition 'order from this big box store and get it delivered to your home' significantly outperformed '30% cash back on your order' — a counterintuitive result that no survey would have predicted, illustrating why marketer intuition and surveys are both unreliable guides. — Kate O'Keeffe, Ep. 55 · cl-kate-okeeffe-007
  • The approach side of preference (likes propagate to similar items via attention) is mirrored by an aversion side that is probably stronger — a single bad experience radiates outward to aesthetically or categorically similar items and is survival-protective, but is routinely overlooked by brands focused only on promoting choice. — Hassan Aleem, Ep. 27 · cl-hassan-aleem-013
  • The biggest measurement frontier in grocery is longitudinal methods that capture what happens outside the store — list-building, smart-home assist, post-purchase use — because the in-store transaction is only a slice of a continuous behavioral arc; diary studies and at-home product sensors are the highest-leverage innovations. — Hassan Aleem, Ep. 27 · cl-hassan-aleem-020
  • The mismatch between what consumers articulate and what they do is an opportunity to disrupt a category: the first brand that lets consumers stop having to choose between competing values wins their preference, and over time that resolved tension becomes the new point of parity while fresh mismatches open up. — Deborah Mendez, Ep. 60 · cl-deborah-mendez-004
  • What looks like an 'unhealthy' food choice may actually be a healthy one in terms of mental and emotional well-being — a parent taking the family through a drive-through on a hard day is choosing family peace, which is a form of health; the food industry thinks too objectively about what health means. — Laurie Demeritt, Ep. 50 · cl-laurie-demeritt-007
  • Adding a map of the vaccination location to a flu-shot reminder email — sent to Yale students and faculty who already knew exactly where the campus health system was — raised participation by a large margin, demonstrating that small environmental cues can outperform direct persuasion. — Ernest Baskin, Ep. 48 · cl-ernest-baskin-014
  • Grocery analytics has the unusual benefit that the bottom line is unambiguous — purchase rates, repeat rates, share-of-wallet — and behavioral scientists should embrace this because, however much brand perception matters, ultimately it is where the wallet speaks that shapes the world. — Hassan Aleem, Ep. 27 · cl-hassan-aleem-008
  • Consumer preferences are not stable traits captured by a single measurement; they change day to day and are reshaped by choice itself — once a shopper picks a brand, the brain constructs a story justifying the pick, and items matching that profile capture more attention next time. — Hassan Aleem, Ep. 27 · cl-hassan-aleem-010
