The average learner does not exist
A companion to Chapter 9 of the book, Think Different in Training Design. The same ideas in several forms: film, conversation, 2 infographics, a mind map and 6 activities. Start with whichever suits you.
Chapter 9 in two minutes
The biggest barriers to effective training are often assumptions nobody examines: that covering material is the same as teaching it, that clear explanation guarantees understanding, that uniform delivery is fair, and that poor results reflect low motivation. Chapter 9 argues these beliefs shape content, structure and pace, and quietly reproduce the same design problems.
One of the strongest is the average learner. Designing for the notional middle of a group simplifies planning, but nobody actually sits there, and most of the cohort is underserved. The chapter asks trainers to shift from subject expert to learning designer: subject knowledge is necessary, but the core question becomes how this group will receive it.
Efficiency is redefined too. Finishing on time is throughput; real efficiency is understanding, retention and application with little wasted effort. Drawing on Argyris and Schön, the chapter treats reflection as design practice, so poor outcomes become design information rather than individual failure. The learner, not the content, becomes the starting point for every session.

Prefer to take it in by eye or by ear? Both cover the core ideas of Chapter 9 in a few minutes.
Film, 1 min
How designing for the average learner fails
Why a session built for the middle of the group serves few of the people actually in it. Captions are built in.
Conversation, 6 min
Why training for average learners fails
A conversation about the assumptions behind familiar training, why they persist, and what changes when the learner becomes the starting point.
