Why One Training Day Never Changes Behaviour
Every L&D team has seen the feedback scores. A training day rated 9 out of 10 for content and delivery, everyone nodding along, flip charts full of good intentions — followed, three months later, by almost no visible change in how people actually manage their teams. The day didn’t fail. The model underneath it did.
The Science Behind the Fade
In the 1880s, psychologist Hermann Ebbinghaus ran a series of memory experiments that produced one of the most important findings in learning science: without reinforcement, we forget the majority of new information within days, and the steepest drop happens almost immediately. It’s known today as the forgetting curve, and it applies just as much to a leadership model taught on a Tuesday as it does to a list of vocabulary words.
Why One Day Was Always Going to Struggle
A single training day, however well delivered, asks people to absorb a full model of behaviour in a few hours and then retain it, unsupported, until a moment weeks or months later when they might need it. By the time that moment arrives, most of the detail has faded. What’s left is a vague sense that there was a useful session once, and not much else to draw on.
What Spacing Does
The research on this is consistent: spaced, repeated exposure to an idea builds retention far more effectively than one concentrated dose. Small reminders, applied close to the moment of use, do more for long-term behaviour change than any single day could. This is the entire logic behind why the best development in any field, from surgery to sport, is structured around repeated practice rather than one intensive briefing.
Designing Around the Curve, Not Against It
Once you accept the forgetting curve as a fact of how people learn, the design question changes. It’s no longer ‘how do we make the training day better’ — it’s ‘how do we support the weeks and months after it, when the fading actually happens.’ That’s a delivery problem as much as a content one, and it’s exactly the gap that sits between most training days and any real change in behaviour.
Why We Built ele on This Principle
This is precisely the gap ele was built to close — spaced, in-context support that sits alongside Crisp’s facilitated programmes, reinforcing what was taught on the day at the exact moments people need it in the weeks that follow, when the forgetting curve would otherwise be doing its quiet work.
