Fig 6. Multiple factor analysis of 353 articles discussing reproducibility, analyzed for 29 themes, with articles grouped by author type.

The size of the square indicates the degree of within-theme inertia. The eight themes with the greatest within-theme inertia are labeled, and partial points for those themes are displayed. Red points indicate the location of those themes in the group of articles authored by scientists, and blue points indicate the theme location for the journalist group. Grey points indicate the location of the articles on the first factor plane.
