Alex Pentland on Decision-making Processes - Dictionary of Arguments
Brockman I 198 Decision-making Processes/Pentland: My students and I are looking at how people make decisions, on huge databases of financial decisions, business decisions, and many other sorts of decisions. What we’ve found is that humans often make decisions in a way that mimics AI credit-assignment algorithms and works to make the community smarter. A particularly interesting feature of this work is that it addresses a classic problem in evolution known as the group selection problem. The core of this problem is: How can we select for culture in evolution, when it’s the individuals that reproduce? What you need is something that selects for the best cultures and the best groups but also selects for the best individuals, because they’re the units that transmit the genes. >Ecosystem/Pentland, >Cybernetics/Pentland. “Distributed Thompson sampling”/Pentland: a mathematical algorithm used in choosing, out of a set of possible actions with unknown payoffs, the action that maximizes the expected reward in respect to the actions. The key is social sampling, a way of combining evidence, of exploring and exploiting at the same time. It has the unusual property of simultaneously being the best strategy both for the individual and for the group. Social sampling: (…) is looking around you at the actions of people who are like you, finding what’s popular, and then copying it if it seems like a good idea to you. Idea propagation has this popularity function driving it, but individual adoption also is about figuring out how the idea works for the individual—a reflective attitude. When you combine social sampling and personal judgment, you get superior decision making. That’s amazing, because now we have a mathematical recipe for doing with humans what all those AI techniques are doing with dumb computer neurons. We have a way of putting people together to make better decisions, given more and more experience. (…) the way you can make human AI, will work only if you can get feedback to them that’s truthful. It must be grounded on whether each per son’s actions worked for them or not. Brockman I 199 The next step is to build a credit-assignment function (>Ecosystem/Pentland).
