Dunbar’s number (150) to identify optimal cohort capacity

Source: Wikipedia, date indeterminate

Dunbar’s number is a suggested cognitive limit to the number of people with whom one can maintain stable social relationships. These are relationships in which an individual knows who each person is, and how each person relates to every other person.[1]

Proponents assert that numbers larger than this generally require more restrictive rules, laws, and enforced norms to maintain a stable, cohesive group. No precise value has been proposed for Dunbar’s number. It has been proposed to lie between 100 and 230, with a commonly used value of 150.[2][3] Dunbar’s number states the number of people one knows and keeps social contact with …

Dunbar’s number provides an upper bound on the number of students who can socially interact with each other within a cohort, which is commonly defined by age/grade-level.

We will have to explore whether there are non-age approaches for defining a cohort.
