Overview of key design features across the 18 visions. The design features on the left capture major recurrent themes that were addressed (positively or negatively) in the Research Topic on OE. The columns indicate to what extent each design feature is a key element (red), actively endorsed (light red), not elaborated upon (white), discouraged (light blue), or strongly discouraged (blue) in each of the 18 visions. Overall, there is wide agreement on the usefulness of most of the features (prevalence of light red and red) and limited controversy (red and blue cells in the same row), indicating an emerging consensus. The 18 visions are indicated by their first author in alphabetical order at the top. The papers are Bachmann (2011); Birukou et al. (2011); Florian (2012); Ghosh et al. (2012); Hartshorne and Schachner (2012); Hunter (2012); Ietto-Gillies (2012); Kravitz and Baker (2011); Kreiman and Maunsell (2011); Kriegeskorte (2012); Lee (2012); Pöschl (2012); Priem and Hemminger (2012); Sandewall (2012); Walther and van den Bosch (2012); Wicherts et al. (2012); Yarkoni (2012), and Zimmermann et al. (2012).
