Saul Wyner

Saul Wyner is 39, a Director of Research, married father of 2, and a 14-year quant/qual UXR, with experience in entertainment, search, cybersecurity, and children’s services, which is another way of saying he gets around. Ex-Google, Microsoft, AT&T, etc, etc. He fled UCLA and the University of Michigan (and all of academia) with a focus on Cognitive Science, Decision Making, and HCI. He also teaches 15th-century German longsword and wrestling, if you’re interested (classes in Hertzelia on Mondays and Thursdays). He resides in Pardes Hannah, Israel, a hippie and art colony that has been described as “the alternative sex capital of Israel”, which means he gets into vaccine arguments on WhatsApp groups regularly.

Mashed potatoes as a lifestyle brand? When AI starts generating user personas for absurd products — and we start taking them seriously — it’s time to ask if we’ve all lost the plot. This sharp, irreverent critique exposes the real risks of using LLMs as synthetic users in UX research.

Have SpudGun, Will Travel: How AI’s Agreeableness Risks Undermining UX Thinking
  • The article explores the growing use of AI-generated personas in UX research and why it’s often a shortcut with serious flaws.
  • It introduces critiques that LLMs are trained to mimic structure, not judgment. When researchers use AI as a stand-in for real users, they risk mistaking coherence for credibility and fantasy for data.
  • The piece argues that AI tools in UX should be assistants, not oracles. Trusting “synthetic users” or AI-conjured feedback risks replacing real insights with confident nonsense.
