Today on Scope Conditions: college dorms shed light on where group culture comes from and how it molds us.

At Harry Potter’s alma mater, each new student is assigned to a House that aligns with their true character. The mystical Sorting Hat takes the courageous ones and sorts them into House Gryffindor, while the studious know-it-alls go to Ravenclaw. The Sorting Hat may be fiction, but it’s actually a lot like life. Much of the social world works this way: whether by assignment or by self-selection, people often end up in social environments that already fit with their pre-existing beliefs and traits.

For social scientists, what’s often called homophily – this tendency for like to attract like – can make it difficult to study the impact of social context itself. Do people tend to believe and act like those around them because they’re influenced by their surroundings, or because they’re drawn to places that already fit their pre-existing characteristics?

Our guest today, Dr. Joan Ricart-Huguet, found a real-world social setting that helps him untangle these possibilities. At East Africa’s oldest institution of higher education, Makerere University in Uganda, incoming students have for decades been allocated to their residence halls by lottery, rather than by personality type. For Joan, Makerere’s randomly assigned dorms have been the perfect laboratory for studying how the cultural characteristics of a social organization arise, endure, and shape people’s beliefs and habits over time. 

Joan is an assistant professor of political science at Loyola University Maryland, and we talk with him about a pair of recent articles he wrote on cultural emergence, persistence, and transmission. Joan tells us about the months of in-depth interviews and immersive fieldwork he conducted on the Makerere campus as well as the natural experiment afforded by random residential assignment that allowed him to test alternative theories of cultural differentiation, reproduction, and impact.

For example, Joan tells us the stories of how distinct hall cultures emerged historically at Makerere – how Livingston Hall came to be known as the residence of respectful gentlemen while Lumumba Hall earned a reputation for rowdy activism. And we learn about the short- and long-term causal effects of these distinct hall cultures on the young adults assigned by chance to live within them.
