    All the Dark Triad and some of the Big Five traits are visible in the face
    (2021) Alper, Sinan; Bayrak, Fatih; Yilmaz, Onurcan; 0000-0001-6350-6234
    Some of the recent studies suggested that people can make accurate inferences about the level of the Big Five and the Dark Triad personality traits in strangers by only looking at their faces. However, later findings provided only partial support and the evidence is mixed regarding which traits can be accurately inferred from faces. In the current research, to provide further evidence on whether the Big Five and the Dark Triad traits are visible in the face, we report three studies, two of which were preregistered, conducted on both WEIRD (the US American) and non-WEIRD (Turkish) samples (N = 880). The participants in both the US American and Turkish samples were successful in predicting all Dark Triad personality traits by looking at a stranger's face. However, there were mixed results regarding the Big Five traits. An aggregate analysis of the combined dataset demonstrated that extraversion (only female), agreeableness, and conscientiousness were accurately inferred by the participants in addition to the Dark Triad traits. Overall, the results suggest that inferring personality from faces without any concrete source of information might be an evolutionarily adaptive trait.

    A tale of two hashtags: An examination of moral content of pro- and anti-government tweets in Turkey
    (2021) Bayrak, Fatih; Alper, Sinan; 0000-0001-6350-6234
    During the campaign period of the 2018 Presidential Election in Turkey, there was a burst in the number of tweets posted by both pro- and anti-government Twitter users. Both sides started their own hashtags and reached a total of 2 million tweets in only one day. We analyzed the content of 186,554 tweets from two opposing ideological camps to test the predictions of Moral Foundations Theory, which suggests that liberals and conservatives endorse different moral foundations. We scored each side's level of emphasis on different moral foundations using the Turkish Moral Foundations Dictionary and compared the two groups. Results revealed that the supporters of the conservative government in Turkey were more likely to endorse care, loyalty, and authority foundations of morality, as compared to those who oppose the conservative government. In addition, the general moral emphasis was higher in the tweets of the pro-government group. Being one of the first studies investigating the moral content of political tweets in a non-WEIRD context, the current study yields important findings regarding the external validity of the Moral Foundations Theory's predictions in different cultures.

    The role of intentionality in perceiving terrorism as a more important problem than traffic accidents
    (2021) Alper, Sinan; Us, Elif Oyku; 0000-0002-6671-2129; AAJ-6747-2020
    We hypothesized that perceived intentionality is one of the factors explaining why terrorism is perceived to be a more important problem than traffic accidents. In Study 1, we conducted an experiment on a large Turkish sample (N = 385) and found that participants suggested allocating significantly more budget to prevent terror-related deaths, as compared to deaths caused by traffic accidents, and this difference was fully mediated by perceived intentionality. In Study 2, which was pre-registered, we hypothesized that American participants (N = 450) would similarly suggest allocating more budget to prevent deaths caused by terrorist incidents, as compared to traffic accidents, but this difference would disappear when traffic accidents are portrayed as involving a perpetrator consciously disregarding the safety of others. Our hypothesis was partially supported. We discuss the potential implications for policy-makers and social psychological research.

    Inferring political and religious attitudes from composite faces perceived to be related to the dark triad personality traits
    (2021) Alper, Sinan; Bayrak, Fatih; Yilmaz, Onurcan
    We used composite face images perceived to have different levels of Dark Triad personality traits (narcissism, psychopathy, and Machiavellianism) and asked participants to predict these target individuals' religious and political identities. In Study 1 (N = 550), Turkish participants rated faces with higher levels of perceived Dark Triad traits as less likely to be religious, to believe in God, and more likely to be left-winger, and to vote for a leftleaning party in all categories except for male narcissism. In a pre-registered follow-up study (N = 1001), we recruited a nationally representative US sample and replicated the same results with minor differences regarding male and female narcissism, and voting preferences. Participants' own political and ideological identities and their stereotypical evaluation of the target groups were mostly ineffective in explaining their predictions. The results suggest that people can perceive faces with higher levels of Dark Triad traits as less religious and less conservative.
