No time to explain — just watch it
Ok, just kidding. Basically, those 4 groups are the key to improve the slides trainer. It seems I should make a few small trainers on the same page, each with 30-40 slides devoted to a specific topic. So that will keep most of the audience engaged (aka “learn more”).
The goal, of course, is to minimize “surfers”, by converting them into other groups via a more structured and small-chunk-style approach. The second part is to convert the rest groups into the Highly Motivated People.
