Prove Learning ROI Like a Regulator
with Matt Lloyd Davies • September 29, 2026
Episode overview
"Budget tells me what you intended to do. Activity tells me what people did. But neither tells me whether the organization is now more capable."Â
Before he built offensive security courses at Pluralsight, Matt Lloyd Davies regulated the UK civil nuclear sector — the skeptical stakeholder whose job was deciding whether the capability an organization claimed was really there. In this episode, we apply that standard of proof to L&D.Â
We cover why the easiest things to measure are the least useful, the three questions that turn learning into a business case, how to answer the "correlation isn't causation" objection, why the "train them and they leave" fear gets it backwards, and how to get executives to define the standard of proof up front.Â
Matt Lloyd Davies is a Principal Security Author at Pluralsight. He holds a PhD in mathematical chemistry and worked in explosives safety research, London 2012 Olympic security, and UK civil nuclear regulation before moving into learning.
