Chat With Myriam Jessier & Giulia Panozzo | The Psychology Behind Search, Biases & AI Behaviour

Filmed On: 3rd October 2025
Host: Sean Barber - /   / seanrbarber   - He & Him

In this episode of Chat With Sean, I’m joined by Myriam Jessier (SEO and technical brand visibility consultant) and Giulia Panozzo (Director of customer acquisition and founder of Neuroscientive)

Together we explore how search behaviour, human psychology, and biases shape how people use Google, LLMs, and AI search — and what it means for marketers today.

📊 Slides included in this video — so you can follow along with Myriam and Giulia’s visuals and examples - https://www.neurospicy.agency/post/se...

Topics covered include:

How authority bias, social proof, and heuristics affect how people search and trust results

Why LLMs reflect and amplify human cognitive biases

The psychology behind visual search and why faces in marketing matter

How to create human-centred content that still works for AI

Why familiarity, emotion, and authenticity are key to trust in 2025

How marketers can use neuroscience and sociology to design better digital experiences

⚠️ Apologies for a few small sound issues during recording — hopefully the subtitles help fill any gaps.
