So these kinds of problems in what I call hybrid systems of humans and machines are a key focus of my lab right now. Margaret Traeger, who's now at Notre Dame, she did a wonderful project in which we made these groups of three humans and a humanoid robot work together to solve a problem.

We manipulated the humanity of the robot. For example, sometimes we had the robot tell stupid dad jokes, like corny jokes. Or we had the robot break the ice by saying, "You know, robots can make mistakes, too." This kind of stuff. And what we found was that the human interactions could be changed by the simple programming of the robot.

We're not attempting to invent super smart AI to replace human cognition. We are inventing dumb AI to supplement human interaction. Are there simple forms of artificial intelligence, simple programming of bots, such that when they are added to groups of humans – because those humans are smart or otherwise positively inclined - that help the humans to help themselves? Can we get groups of people to work better together, for instance, to confront climate change, or to reduce racism online, or to foster innovation within firms?

Can we have simple forms of AI that are added into our midst that make us work better together? And the work we're doing in that part of my lab shows that abundantly that's the case. And we published a stream of papers showing that we can do that.

There are thousands of chemicals in our water, just like there are in air, just like there are in food. We sometimes compartmentalize too much. We forget, but what is food? Food is made up of chemicals. And I think we need to be broader in our understanding because, for example, we all have on us and within us our Microbiomes and we think about the GI bacteria and we now know that if people are obese they have very different microbial content in their gut compared to people who are not obese. And we know that a baby born by C-section section has a different position than a baby born vaginally. And we know that these things have impacts. We know that many of the bacteria have the ability for example to metabolize the contaminants as well as things in our food. And we know that you can have a different response depending upon what people are eating.
