Who This Is For

Transform daily challenges into confident, evidence-based decisions

Designers

Subjective → Scientific

Challenge: "I don't like the blue" feedback loops that replace user-centered logic with stakeholder whims.

With Principles: Justify every design decision with 2,098+ citations and stop defending your work with opinions.

Product Managers

Features → Outcomes

Challenge: Roadmaps filled with "nice-to-haves" that ship on time but fail to move engagement metrics.

With Principles: Prioritize features based on behavioral psychology to predict exactly what drives user retention before you build.

Developers

Guesswork → System

Challenge: Vague design handoffs force you to improvise interaction logic, creating inconsistent UX debt.

With Principles: Code with confidence using standardized heuristics that define exactly how the UI should behave.

Decision Makers

Opinions → ROI

Challenge: High-stakes product strategy determined by the loudest voice in the room rather than data.

With Principles: De-risk your roadmap by grounding investments in a peer-reviewed framework validated by industry leaders.
