Internal opinions override buyer evidence because data often takes a back seat to gut feeling when there is disagreement on critical decisions, and because teams instinctively look for stories that validate their own point of view rather than the customer's. When there is less data in the room, the loudest voice wins. Buyers are 20% more likely than vendors to say statistical evidence is trustworthy (51% of buyers versus 32% of vendors), revealing a fundamental gap between what companies believe is persuasive and what actually persuades. Lower-level executives tend to rely on opinions versus evidence, while senior executives are more likely to arrive armed with data. Cognitive bias compounds the problem: only an estimated 5% of decision-making is conscious, meaning even well-intentioned teams bring subconscious preferences to website decisions. Internal documentation must accurately represent actual processes; if disagreement exists about how things work, the documentation (and the website messaging that reflects it) needs revision before any design or content decisions will produce reliable results. ### Ask AI about Lean Labs [ ![](https://www.leanlabs.com/hubfs/LL%20v5/Images/Logos/chatgpt.svg) ChatGPT ](https://chat.openai.com/) [
