Middle Ground, funded by the National Science Foundation, was an outdoor public installation developed by the Exploratorium and located in the Civic Center. This installation focused on the social science of how people think about others, particularly the cognitive basis for biases, judgements, and stereotypes, as well as more pro-social behavior and ways of connecting with others. Garibay Group is currently conducting a summative evaluation. As data are still being collected and analyzed, this report presents select preliminary results about installation-specific outcomes.
