The Power of Instinct: How Customers Really Make Decisions
Almost everything in marketing rests on a premise that turns out to be false: that people weigh their options and decide rationally. They don’t. Leslie shows how the instinctive mind actually works, why the brand with the strongest network of positive associations wins before the comparison even begins, and what that means for anyone trying to grow.
Audience takeaways
- Why persuasion underperforms and instinct outperforms
- How to read the web of associations a brand already owns
- The first three moves that shift instinctive preference
Traditional Marketing Is Dead: Breakout Growth Requires a New Playbook
Delivered to the Harvard Business School Women’s Association.
Segmentation, funnels and persuasion were all built for a deliberate, conscious decision-maker who does not exist. Leslie lays out what replaces them, and why the teams chasing their most loyal customers are the ones quietly capping their own growth.
Audience takeaways
- Why targeting the loyal few puts a ceiling on growth
- The case for competing for the entire category, not a segment
- How to brief a team against instinct rather than demographics
