Biography cosine similarity in predictions as a function of disclosure tendency and number of friends. The left panel shows the median cosine similarity of predictions and of the Null Model in 1000 samples for each value of ρ with bars showing 95% bootstrapping confidence intervals. The cosine similarity of predictions outperforms the Null Model for \(\rho>0.2\) and increases with ρ. The right panel shows the regression analysis of cosine similarity versus number of friends in Twitter, revealing a trend of increasing similarity with number of friends for the different values of ρ.
