For years, researchers have argued that social influence hurts collective intelligence, causing individuals to be swayed by others, ultimately leading to "groupthink". In a study on the network dynamics of social influence, we find something different! It's not social influence, but social structure, that is the difference between collective intelligence and group madness. We found that changes in the structure of the interaction network can predictably cause increases or decreases in group intelligence.

In my last post, I talked about a recent study of mine regarding category systems in small vs large populations. Pictured here are the results of that 2021 study.

The first image has several "mountains" on the image continuum, which demonstrates that in smaller populations, there is a wide range of variation in the categorization of ambiguous stimuli (the purple figures at the bottom of the graph). When you swipe to see the results for large populations, a very interesting pattern emerges... ➡️

Remember my earlier posts on "category convergence

Remember my earlier posts on "category convergence"? It's worth wondering how we were able to discover those findings. In our 2021 paper, "Experimental evidence for scale-induced category convergence across populations", we asked participants in small and large populations to categorize visually ambiguous images (like the one pictured above).

If you were asked to categorize different shapes, do you think you would have an easier time doing it by yourself or with a large group? What about with people from other populations? Do you think you could all easily agree?

Recently, the White House employed TikTokers to promote the COVID-19 vaccine. In my article for the Philadelphia Inquirer, I argue that there is a stark differnce between having the social status of "influencer" and actually influencing change.

Real influence, like pursading people to get vaccinated, requires changing beliefs and behaviors, which is much more complex and difficult than influencing people to purchase something. Read more about it here: https://bit.ly/3HS2A7V

The most popular approaches for encouraging vaccination focus on how to get the right message.

But, more important than the message is where that message takes hold within the social network. It's not about special people, but about special places. Specifically, clusters of redundant ties within the network have been found to make a difference when it comes to initiating vaccination messages in a way that triggers real change in people's behaviors and beliefs.

Happy Martin Luther King Jr. Day! Today, it is important to adknowledge the sacrifices of countless members of our extended social networks who have made change like the Civil Rights movement possible.

As we celebrate iconic figures in the history of social change, like Dr. Martin Luther King and Rosa Parks, it is also essential to remember people like Claudette Colvin. Ms. Colvin, along with many other young women, were part of the struggle for civil rights and arrested for protesting bus segregation in Alabama. Activists like Ms. Colvin are how we activate a broader network of change.

In my last post, I talked about evidence for a phenomenon called "category convergence", but what is it? Swipe to learn more! ➡️

For a long time, it was widely accepted that large, independent populations would evolve completely unique ways of classifying new or obscure phenomena. It is intuitive that depending on your culture and life experiences, you would categorize new things and situations very differently.

But our research has been uncovering a radically different story. We now have considerable evidence for something called "category convergence" across large populations. This spans countries and cultures. In a recent study, we focus specifially on how people from around the world would classify novel kinds of visual stimuli.
