Note: All models are random-effect hierarchical linear regressions (HLM) where candidates are nested within elections. Minimum two experts per candidate. a “Relative success” is measured as the ratio between the percentage of votes for the candidate and the “average” percentage that a candidate should have received (100% / number of effective candidates). Thus, a relative success of 250 means that the candidate received 2.5 times the votes of the average candidate in that election. b “Divergence with the average result” is calculated as (100% / number of effective candidates). Thus, a divergence of 15 means that the candidate received 15% of votes more than the “average” candidate. Coefficients in bold are statistically significant (normal bold significant at p < .05 or lower; in italics significant at .05 < p < .1); see p-value.

20 Appendix C Measures of personality reputation
To measure the five socially desirable personality traits (Big Five) we rely on the Ten Items Personality Inventory (TIPI; Gosling et al. 2003). For each trait experts had to evaluate two statements (e.g., the candidate might be someone that is ‘critical, quarrelsome’) and the underlying personality trait exists as the average value for those statements. Remember that, to keep the length of the questionnaire at bay, experts had to answer the following battery of questions regarding the Big Five for one randomly selected candidate only. The battery of questions used to measure the Big Five in our questionnaire is presented as follows:
Q. Here are a number of personality traits that may or may not apply to [candidate X]. Please indicate the extent to which you agree or disagree with the following statements. You should rate the extent to which the pair of traits applies to [candidate X], even if one characteristic applies more strongly than the other. In your opinion, [candidate X] might be someone who is... … Extraverted, enthusiastic (c1) … Critical, quarrelsome (c2) … Dependable, self-disciplined (c3) … Anxious, easily upset (c4) … Open to new experiences, complex (c5) … Reserved, quiet (c6) … Sympathetic, warm (c7) … Disorganized, careless (c8) … Calm, emotionally stable (c9) … Conventional, uncreative (c10) [0 ‘disagree strongly’, 1 ‘disagree somewhat’, 2 ‘neither disagree nor agree’, 3 ‘agree somewhat’, 4 ‘agree strongly’]
The five personality traits exist as average values of pairs of statements, as follows (direction of some items reversed): extraversion (c1 and c6), agreeableness (c2 and c7), conscientiousness (c3 and c8), emotional stability (c4 and c9), and openness (c5 and c19).
The measure of the three “dark” personality traits (Dark Triad) follows the approach used above for the Big Five, where each trait is measured through two separate and independent components. We designed a battery of six items to measure the three “dark” traits, based on the principal component analyses described in Jonason and Webster (2010: 422). For each dark trait we identified the two items that correlate the highest with the trait, and used them as items in our battery. The battery of questions used to measure the Dark Triad in our questionnaire is presented as follows:
21
Q. Next, please indicate the extent to which you agree or disagree with the following statements, related to personality traits that may or may not apply to [candidate X]. In your opinion, [candidate X] might be someone who... … Wants to be admired by others (c1) … Shows a lack of remorse (c2) … Might manipulate others to succeed (c3) … Wants attention from others (c4) … Tends to be callous or insensitive (c5) … Tends to use flattery to succeed (c6) [0 ‘disagree strongly’, 1 ‘disagree somewhat’, 2 ‘neither disagree nor agree’, 3 ‘agree somewhat’, 4 ‘agree strongly’]
As for the Big Five, the three “dark” personality traits exist as average values of pairs of statements, as follows: narcissism (c1 and c4), psychopathy (c2 and c5), and Machiavellianism (c3 and c6).
Tables C1 and C2 below present bivariate correlations across all components of benevolent and dark personality traits. Cells highlighted in grey represent combinations of two statements that are averaged to produce a measure for a given trait (e.g., for Table C1, c1 and c6 are averaged to create a measure of extraversion).
Table C3 compares the profile of four candidates (Trump, Rutte, Wilders and Merkel) in two samples: our experts, and students at the University of Amsterdam. As the table shows, the average profile of the four candidates in the two samples is quite consistent.
