ALEX 'SANDY' PENTLAND is a pioneer in big data, computational social science, mobile and health systems, and technology for developing countries. He is one of the most-cited computer scientists in the world and was named by Forbes as one of the world's seven most powerful data scientists.
In this interview, he discusses how BIG DATA changes the picture completely of how we will change systems of discovery, as the sheer amount of information can make anything look statistically significant. Rather, with all of this information, we must explore the causal nature of correlations, rather than just flatly assuming they are true.
To quote him:
"The notion that it is connections between people that is really important is key, because researchers have mostly been trying to understand things like financial bubbles using what is called Complexity Science or Web Science. But these older ways of thinking about Big Data leaves the humans out of the equation. What actually matters is how the people are connected together by the machines and how, as a whole, they create a financial market, a government, a company, and other social structures.
Because it is so important to understand these connections Asu Ozdaglar and I have recently created the MIT Center for Connection Science and Engineering, which spans all of the different MIT departments and schools. It's one of the very first MIT-wide Centers, because people from all sorts of specialties are coming to understand that it is the connections between people that is actually the core problem in making transportation systems work well, in making energy grids work efficiently, and in making financial systems stable. Markets are not just about rules or algorithms; they're about people and algorithms together."
