Social hierarchies are important, especially in the workplace where understanding the chain of command is crucial. Workers need to know who they can turn to for help, who they have to watch out for, and who they need to take orders from. This is a learning process that can take a while, but a study by researchers from London College and DeepMind have found that it is a process that makes significant use of the prefrontal cortex of the brain.
Researchers had participants undergo an fMRI while they imagined themselves as employees at a fictional company. Researchers then had the participants watch video interactions between “coworkers” to determine who “won” those interactions. Whoever won the interaction was determined to have more power in the hierarchy. Participants also watched similar videos but this time, they were asked to imagine their friend as an employee there. The findings show that we’re better at understanding the hierarchies to which we belong than those of others, which makes sense.
So what good is this research? Knowing what part of the brain is used in learning something that we pick up more or less “by instinct” may not sound immediately useful, but that’s because it’s part of a long-term project to help develop better artificial intelligence. That’s what DeepMind works on, actually.
DeepMind is trying to develop AI that can be applied to “some of the world’s most intractable problems.” If you’ve ever seen a movie about a robot, you know how hard it is for them to understand humans. By having a better idea of how our brains process human interactions, we can develop AI systems that better understand human interactions. Along the way, perhaps future research in this area will help us to better understand how we interact and maybe get a head start on fixing those problems before the robots are ready to help.
