Leadership training is rarely short on inspiration, but it’s often short on impact.

In this episode of Sticky From The Inside, Andy Goram is joined by Dr Jenn Yugo, Managing Director of Corvirtus and an industrial–organisational psychologist, to explore why so much leadership training fails to create lasting behaviour change.

Jenn explains that the problem isn’t motivation, effort, or even the quality of the training itself. It’s that organisations treat behaviour change as a one-off learning event rather than a system supported by environment, habits, identity and social reinforcement.

Together, Andy and Jenn unpack what the science of behaviour change actually tells us, from the forgetting curve and feedback loops, to the powerful role of values, authenticity and team involvement. This conversation challenges the idea that leaders need to “do more”, and instead reframes leadership growth as doing things differently, consistently, and together.

If you’ve ever wondered why great leadership intentions fade once people return to the day job, this episode offers a grounded, human, and evidence-based answer.

• One-off learning moments aren’t enough. The forgetting curve shows how quickly knowledge fades without reinforcement.
• Leadership training isn’t a motivation problem, it’s a behaviour change problem. Jenn reframes development as sustained behavioural shift, not information intake.
• Environment beats willpower. Feedback loops, systems and social support matter more than personal discipline.
• Lasting change is social, not solo. Leaders who involve their teams in their development see far greater impact over time.
