What explains this single predictor variable outcome? 1) Narcissism (NPQC-R Total) entered first, because it had the strongest Pearson correlation with Ratings. 2) Neither Age nor Gender had significant Pearson correlation with Ratings. 3) Extroversion was not included (although it had a significant Pearson Correlation with Ratings) because it correlated highly with Narcissism. 4) All of the above are true. 5) I have no idea of what is true after 4 years of President Donald Trump.
