Previous research has shown that evidence can help conflicting parties move past their differences by temporarily offering them a set of principles to which they all can ascribe. EBPM also gives people the tools to scrutinise decisions, and comes with transparent procedures. However, our study shows that working based on EBPM principles does not always help policy conflict. We looked at the way in which a piece of evidence called the Environmental Impact Assessment (EIA) impacted existing conflicts in three large infrastructure projects in Flanders. The observed processes revolved around determining the preferred option among multiple proposed solutions for an infrastructural issue that needed to be addressed. We found that, in these processes, the introduction of an EBPM-type instrument such as the EIA also created confusion.
