Humans are social, and our learning should be, too.
Humans are social creatures, so much so that social interactions change the way our brain functions. Social context impacts our attention, affects our motivation, and makes us learn and act on new information in different ways.
Yet these effects are all dependent on our sense of belonging and psychological safety. In one example, a 1999 study by Amy Edmondson demonstrates that psychological safety within work teams––and the interpersonal risk-taking it facilitates––both lead to better learning outcomes.
The basics of cohort design
Researchers have identified a number of factors that enhance the “entitativity,” or “groupiness,” of cohorts, as well as cohort members’ associated sense of psychological safety and belonging. At Nomadic, we’ve discovered that three aspects of cohort design are particularly important for fostering this.
1. Choose the right cohort size.
Too many people in a cohort means that participants will be overwhelmed by a flood of comments, group identity will never coalesce, and individual voices will begin to feel unimportant. Too few cohort members, on the other hand, and discussions will become weaker, with little opportunity for interaction with a range of fellow learners. To design social and digital learning environments that mirror real working environments, cohort size should reflect the scale of typical extended working teams. Over the years, Nomadic has found that a cohort size of 50–100 learners is usually best.
2. Create diverse cohorts.
When we first started delivering cohort-based learning experiences to clients, we assumed that relatively homogenous cohorts—in terms of job level, nationality, function, and so on—would perform best. We were wrong. Diverse cohorts, it turns out, generate more engagement and better learning outcomes. Within the IBM marketing organization, for example, we saw that randomly generated teams of marketers regularly outperformed intact working teams. Similarly, in our leadership academy’s global edition, teams of learners from different organizations and countries regularly outperform teams whose members all come from one organization. These results align with management research demonstrating that though homogenous teams can feel more comfortable for members (especially at the time of team formation), in the long run, diverse teams demonstrate deeper learning and better performance.
3. Foster cohort cohesion through shared rituals.
People respond to cues that make them feel like they’re part of a larger group. These cues can take many forms; anthropologists have studied rituals structured by music and coordinated movement, while management scholars have shown that teams of business school students who regularly share meals generate higher profits in simulated negotiations. Similarly, researchers have also demonstrated that teams function better after they train together, committing fewer errors and working together more effectively. This dynamic holds true across a wide array of industries, with an enormous amount of interdisciplinary research showing that rituals increase group cohesion and collaboration overall.

Although small, these small design differences can really make a difference in each learner’s feeling of psychological safety, leading to behaviors that will increase the effectiveness of the cohort model and ultimately, drive great learning and business outcomes.
