Modern marketing teams are obsessed with data.

But what if the very thing you trust is limiting your results?

The book introduces a different way of thinking about growth and decision-making.

Direct Answer: Why Can Too Much Data Hurt Conversions?

Why Metrics Feel Like Control

Data gives the illusion of certainty.

You can measure almost everything.

Metrics show behavior, not meaning.

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

Testing cannot fix flawed thinking.

• It focuses on small changes
• It ignores deeper decision drivers
• It misses systemic problems

The Real Model: Perception Over Data

Instead of relying on dashboards, the book introduces a simple idea: people compare what they get vs what they give.

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.
