Peer-Reviewed Journals: Findings are sourced from high-impact journals including ScienceDirect, Psychological Science, the Journal of Consumer Research, and the Journal of Marketing Research.
Foundational Psychological Theories: The framework is built on established principles like John Sweller’s Cognitive Load Theory, Miller’s Law regarding working memory limits, and Uncertainty Reduction Theory.
Neuro-behavioural Research: Data is derived from studies using eye-tracking, EEG (electroencephalography), and physiological measurements such as heart rate and skin conductance to track how anxiety impacts user scanning patterns.

Industry Research and UX Authorities

Specialised Research Houses: Extensive use is made of the Baymard Institute, which contributed over 88,000 hours of usability testing and 14 years of checkout tracking, and the Nielsen Norman Group (NN/g), pioneers of the “progressive disclosure” principle.
