Ep 2.24 The Decision Threshold Matrix: Why Patient Motivation Isn't Fixed and What It Means for Trial Recruitment

In this episode, Liam and Ted explore one of the most underexamined problems in clinical trial recruitment: patient motivation is not static. 

Drawing on real-world experience from a late-night participant funnel audit to an insomnia study no-show Liam introduces two interconnected frameworks: the Decision Threshold Matrix and the Trial Value Equation.

The matrix maps patient motivation across four quadrants defined by disease severity and perceived treatment adequacy. It breaks down how patients unconsciously calculate whether participation is worth it and why trial teams consistently inflate the denominator (burden) without strengthening the numerator (benefit). 

Together, these tools offer a behavioral science-grounded lens for understanding when, why, and how patients engage with research and what teams can do about it.

This episode is for anyone working in patient recruitment, site management, or protocol design.
