Does clustered presentation lead readers to diverse selections?

A recent study found that presenting news suggestions as clusters in a sidebar can lead to more exploration of articles and clusters related to particular stories [1]. We conducted a lab study to test the robustness of the result.Our results only partially replicate the original findings: people read more articles, but not from significantly more clusters;we also foundthat they prefer the clustered presentation. Further research is needed to better understand the conditions under which clustered presentation leads people to sample from more clusters.
