Fig 1.
Faces of CEOs (in 3 test-groups, n = 524 in each test group) compared to citizens (n = 79 in each test group).
Each test line represents a test for a different random composition of CEOs and citizens in the training and test group. For each test, the training group is 150 for CEOs and 150 for citizens, so the remaining faces fall into the test group of CEOs (n = 524) and citizens (n = 79).

Fig 2.
Faces of CEOs (n = 524) compared to Professors (n = 102) The red line represents a test for a random composition of CEOs and professors in the training and test group.
For each test, the training group is 150 for CEOs and 150 for professors, so the remaining faces fall into the test group of CEOs (n = 524) and professors (n = 102).
