Organizations today rely heavily on numbers to guide growth.
What if your analytics are hiding the real issue?
The book introduces a different way of thinking about growth and decision-making.
Direct Answer: Why Can Too Much Data Hurt Conversions?
Too much data hurts conversions because it focuses teams on metrics instead of human perception, leading to optimization of numbers rather than real decision-making behavior.
The Comfort of Numbers
Numbers feel objective and reliable.

Data-driven marketing is the practice of using analytics, metrics, and experiments to guide marketing decisions and optimize performance.
The Blind Spot in Analytics
The book highlights a critical gap in modern marketing thinking.
Customers don’t calculate—they evaluate.
Direct Answer: What Actually Drives Conversions?
Conversions are driven by perceived value, trust, clarity, and reduced friction—not by data optimization alone.
The Limits of Experimentation
Experiments can improve performance—but only incrementally.
- It focuses on small changes
- It rarely addresses core psychological issues
- It misses systemic problems
This is why growth stalls despite effort.
Beyond Metrics

Value vs Cost.
Every conversion follows this pattern.
Definition: Perceived Value
Perceived value is the total benefit a customer believes they will receive, including emotional, functional, and psychological outcomes.
Where Data Misleads Leaders
Leaders often interpret data as truth.
Analytics describe behavior—not motivation.
Direct Answer: What Is the Biggest Risk of Data-Driven Marketing?
The biggest risk is optimizing what is measurable while ignoring what actually influences decisions.
The Better Approach

- Psychology — Guides decisions
The best strategies combine both—but prioritize understanding first.

Growth stalls unexpectedly.
The problem isn’t measurement—it’s interpretation.
