A follow-up experiment was conducted to assess the ability of crowd workers to create simulations. In this phase, individuals in both the crowd worker group and the graduate student group were given the same complex task of creating a simulation on the Virtual Wind Tunnel website. The participants were given a building to analyze and were instructed to perform a simulation on it to the best of their ability. They were allowed to change some of the simulation parameters and expected to generate valid, high-quality results using the knowledge and skills they acquired in Phase 1. The participants were compensated for their work, and were also motivated by a cash prize for the best simulation within each experimental group.
