The Trust Spectrum
Today I want to share with you a design framework that I’ve been working on for a couple of years now with a team at Googleโs Advanced Technology and Projects (ATAP) group, led by Aaron Cammarata. We call it “The Trust Spectrum,” and it’s a practical design lens for designing multiplayer games, particularly ones involving co-operative play.
Background
Aaron led the charge on this project; he formed a group devoted to games that could enhance social connection, and asked me to help out on the game design mechanics side of things. He spent several months reading deeply into psychology and sociology to learn what the latest science said about human connections and social behavior.
In Aaron’s research on social structures, a few things popped out rather quickly.

The intent of this talk was to do a “powers of ten” sort of look at multiplayer mechanics… not really to describe anything new, but instead to try to take the whole big spectrum of what we think of as multiplayer game design, and do a cross-disciplinary look at it. I covered a bit of game theory, a bit of psychology, a bit of evolutionary biology, a touch of history, a heavy dose of sociology, a dash of social networking theory, and of course, game design stuff.
