In this episode of the Greenbook Podcast, Karen Lynch speaks with John Gilfeather, President of John Gilfeather & Associates and 2026 Market Research Council Hall of Fame inductee for Lifetime Achievement. John reflects on a career that spans Yankelovich, Roper, TNS, Logica Research, and his own consultancy, sharing lessons from decades of B2B, public affairs, corporate reputation, and public-release research.

The conversation explores what makes research “good,” why mentorship matters, and how industry disruptions—from telephone to online to AI—have changed the craft. John also offers a thoughtful warning about preserving questionnaire quality, human judgment, and client impact as the insights industry evolves.

Key Discussion Points:

  • John’s early career at Yankelovich and the foundations of serious, craft-driven research
  • The role of corporate reputation research in shaping stakeholder behavior
  • How methodologies have evolved from in-person interviews to phone, online, and AI-enabled research
  • Why “good research” must help clients make better decisions
  • Mentorship, industry ethics, and the importance of training the next generation of researchers
