The replication of, or perhaps the replicability of, research is often considered to be a cornerstone of scientific progress. Yet unlike many other disciplines, like medicine, physics, or mathematics, we have almost no drive and barely any reason to consider replicating the work of other HCI researchers. Our community is driven to publish novel results in novel spaces using novel designs, and to keep up with evolving technology. The aim of this workshop is to trial a new venue that embodies the plans made in previous SIGs and panels, such that we can begin to give people an outlet to publish experiences of attempting to replicate HCI research, and challenge or confirm its findings.
