Social Technology by Marti A. Hearst We are in the midst of extraordinary change in how people interact with one another and with information. A combination of advances in technology and change in people's expectations is altering the way products are sold, scientific problems are solved, software is written, elections are conducted, and government is run. People are social animals, and as Shirky notes, we now have tools that are flexible enough to match our in-built social capabilities. Things can get done that weren't possible before because the right expertise, the missing information, or a large enough group of people can now be gathered together at low cost. These developments open a number of interesting questions for NSF and CISE. What are the key research problems? How should these developments change how research is conducted? How can the intersection of social science and technology research be aided or improved? And how should this effect how NSF researchers get involved with relevant government efforts, including transparent government, emergency response, and citizen science? In this talk I attempt to summarize and put some structure around some of these developments.
