Breakthroughs in Understanding Social Hierarchies Lead to Advanced AI

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.

Americans Are Apprehensive About “Enhancing” Human Abilities

For years, there’s been speculation about scientists being able to enhance human abilities through advanced technology. But what was once dismissed as mere conspiracy theory may become a reality sooner than we think.

For fans of science fiction, the idea of humans artificially enhancing their abilities (by implanting computer chips or genetically modifying embryos to protect against various diseases or disorders) is a pretty familiar idea. And some of those technologies are likely to arise within the next few decades, but with that technology comes some serious concerns.

According to a recent survey conducted by the Pew Research Center, while many Americans believe that we’ll be able to transplant artificial organs, cure most cancers, or implant computer chips into our bodies within the next fifty years, they aren’t quite sold on whether or not we should actually do those things. The survey asked people how likely they would be to have computer chips installed into their brains, get synthetic blood transfusions, or edit their babies’ genes. About a third of respondents said they would consider having a computer chip installed into their brain or get a synthetic blood transfusion. Meanwhile, just about half said they would consider editing their babies’ genes.

Among the findings, the Pew Research Center concluded that Americans with strong religious identities were less likely to want such procedures, and more likely to think that they were a bad idea in general, stating that such procedures were crossing the line by interfering with nature. However, people were also more likely to considering undergoing an enhancement if it were controllable or reversible, or if those enhancements would bring about a sort of health equality. People were less likely to think it is okay for synthetic blood to make people faster or stronger than they are, or to let computer chips improve cognitive abilities.

The survey tells us that overall, Americans are confident that science will continue to advance human capabilities as we move forward, but our fears about such procedures might outweigh the potential benefits. While curing cancer seems like an easy sell, implanting computer chips into our brains seems like it might be slightly harder to pull off.
