Spread of Innovations: This experiment explores how innovative ideas spread in
a group. As you try to solve a puzzle, you see the solutions proposed by your
neighbors, and they see your solutions.

Opinion Sharing: You rate things (e.g. faces, music, or paintings) and can see
the ratings given by others. Over several rounds of ratings, does your group
converge in its opinion or not?

In all of these experiment, you play with other humans when they are available
or with artificial intelligence bots when no other humans are currently on-
line. By playing our games, our GEE group benefits because we collect data on
how collective behavior in human groups emerges, and you benefit by  

1. learning about current research questions and methods in the social sciences,
2. sharing an engrossing, communal experience with others people (or bots!),
3. playing games that have deeper significance and more interesting dynamics

than solitaire, tetris, or the typical fodder of on-line games. The
experiments will run on any computer that has Java 1.4 or later, and can be
found at:

If you like the experiments, please tell your friends or favorite news group,
blog, or forum. The more people who are in our virtual world at any time, the
more fun it is (and the more data we collect). Also, please reply to this
email is you would like to be placed on our mailing list, or if you’re willing
to place a link to our site on your web page. If you find any bugs or have
suggestions for improvements, please email Andy Jones, <andjones@indiana.edu>
or Allen Lee <alllee@cs.indiana.edu>, and CC Rob Goldstone
