These insights are applicable to training and development as well and particularly to a discussion about the ideal class size for training. There are obvious advantages to one-on-one training with regards to such issues as intimacy, customization, and so forth.

There are obvious scale advantages to training in larger groups. While there are always going to be situations where going small or going large makes sense, if you follow the implications of the anthropological research, you should bias your training to groups of six to eight.

The primary interactions are between teacher and learner, not between group members. The learners learn from the teacher, not from each other. This is, of course, wonderful if the teacher is good. It’s less wonderful if the teacher is not so good.

The argument against classes of more than nine people is that they default to lectures. The ability of any individual to hide in the class increases with the size of the class. You don’t want people to hide. You want them to engage with the material and with each other. Too big is too bad.

Groups of six to eight people are large enough to have diversity of thought and small enough to encourage and enable engagement. Learners can interact with the material, the teacher and with each other. They can get to know each other. They can learn to trust each other.
