Case Study 5:
The Great Social Learning Tournament

social learning


Culture evolves as animals find ever more efficient ways of learning from others.  To uncover the best learning rules we organized a scientific competition where we invited people to suggest alternative learning strategies, offering a prize for the most effective one. The entries were pitted against each other in a computer tournament so that natural selection could choose the best strategy. Over 100 researchers entered from around the world, including biologists, economists and mathematicians.

The winning strategy, submitted by Canadian neuroscientist Tim Lillicrap and mathematician Dan Cownden, copied almost exclusively, cleverly weighting information according to how old it was and estimating for how long particular actions would be useful.  The tournament helps us to understand why copying is widespread in nature and why humans are so good at it. You can play the same game at the 'Culture Evolves' stand and website.
