The results presented in Fig. 2 show that computers’ average accuracy across the Big Five traits (red line) steadily grows with the number of Likes available on the participant’s profile (x axis). Computer models need only 100 Likes to outperform an average human judge in the present sample (r = 0.49; blue point). Compared with the accuracy of various human judges reported in the meta-analysis (20), computer models need 10, 70, 150, and 300 Likes, respectively, to outperform an average work col- league, cohabitant or friend, family member, and spouse (gray points). Detailed results for human judges can be found in
