The Liking-Similarity Effect: Perceptions of Similarity as a Function of Liking

Give Me a Straight Answer: Response Ambiguity Diminishes Likability

Across nine experiments (eight preregistered) involving Western and Asian samples, we showed that people providing ambiguous (vs. specific) responses to questions in various social scenarios are seen as less likable. This is because, depending on the social context, response ambiguity may be interpreted as a way to conceal the truth and as a sign of social disinterest. Consequently, people reported lower inclination to befriend or date individuals who appeared to provide ambiguous responses. We also identified situations in which response ambiguity does not harm likability, such as when the questions are sensitive and the responder may need to "soften the blow." A final exploratory study showed that response ambiguity also impacts personality perceptions-individuals providing ambiguous responses are judged as less warm, less extraverted, less gullible, and more cautious. We discuss theoretical implications for the language psychology and person perception literatures and practical implications for impression management and formation.

Noncoding SNP at rs1663689 represses ADGRG6 via interchromosomal interaction and reduces lung cancer progression

A previous genome-wide association study (GWAS) revealed an association of the noncoding SNP rs1663689 with susceptibility to lung cancer in the Chinese population. However, the underlying mechanism is unknown. In this study, using allele-specific 4C-seq in heterozygous lung cancer cells combined with epigenetic information from CRISPR/Cas9-edited cell lines, we show that the rs1663689 C/C variant represses the expression of ADGRG6, a gene located on a separate chromosome, through an interchromosomal interaction of the rs1663689 bearing region with the ADGRG6 promoter. This reduces downstream cAMP-PKA signaling and subsequently tumor growth both in vitro and in xenograft models. Using patient-derived organoids, we show that rs1663689 T/T-but not C/C-bearing lung tumors are sensitive to the PKA inhibitor H89, potentially informing therapeutic strategies. Our study identifies a genetic variant-mediated interchromosomal interaction underlying ADGRG6 regulation and suggests that targeting the cAMP-PKA signaling pathway may be beneficial in lung cancer patients bearing the homozygous risk genotype at rs1663689.

A teacher like me? Different approaches to examining personality similarity between teachers and students

Research suggests that people tend to like others more if they are similar rather than dissimilar to themselves. Likewise, students may tend to prefer teachers with whom they share similar personality characteristics. To test this hypothesis, we examined the role of personality similarity between students and teachers in predicting how much students liked their teachers. Secondary school students ( N = 634) provided self-reports and reported on their teachers’ personality using a Big Five personality scale. Their teachers ( N = 31) also provided self-reports. These reports were then used to compute three indices of similarity; i.e. perceptual similarity, actual similarity, and perceptual accuracy which were used to explain teacher liking. Multilevel linear models showed that perceptual similarity (computed as the profile agreement across student self- and teacher-ascribed Big Five traits) had the largest effect on teacher liking. Teachers described as more agreeable and conscientious were liked by their students more. Findings highlight the importance of considering students’ perceptions of personality similarity with their teachers for understanding how students feel “connected” to their teachers and positively interact with them.

The Relationship Between Follower Affect for President Trump and the Adoption of COVID-19 Personal Protective Behaviors

In the current series of studies, we draw upon implicit leadership theories, social learning theory, and research on decision making to investigate whether affect toward President Trump explains U.S. residents’ evaluations of his leadership during the COVID-19 crisis, as well as the likelihood that that residents engage in personal protective behaviors. A meta-analysis using 17 nationally representative datasets with a total of 26,876 participants indicated that participants who approve of President Trump tend to approve of his leadership regarding the COVID-19 pandemic and were less likely to engage in personal protective behavior (PPBs; i.e., hand washing, wearing a mask or other face covering in public, and social distancing). On the other hand, those disapproving of President Trump also tended to disapprove of his leadership during the COVID-19 crisis and were more likely to engage in PPBs. In a second study, using an established measure of leader affect (leader affect questionnaire) and controlling for political party, we replicated and extended these results by demonstrating that expending cognitive effort toward understanding the COVID-19 crisis attenuated the relationship between affect toward President Trump and (1) approval of his leadership during the COVID-19 crisis and (2) engagement in some, but not all, PPBs.

Understanding Bias in Surgery: Perceived Cultural Similarity Between Surgeons and Patient Families

OBJECTIVE

We describe surgeon and parent perceptions of similarity toward each other and evaluate differences in the perceptions of similarity by race.

STUDY DESIGN

Observational cohort analysis.

SETTING

Three outpatient sites.

METHODS

Following consultations for children undergoing evaluation for 1 of 3 surgical procedures (tonsillectomy, hernia repair, circumcision), surgeons and parents rated their perception of cultural similarity toward each other on a 6-point Likert scale. Surgeon evaluation of 9 parent characteristics was measured with 7-point Likert scales. Regression analyses were performed to identify predictors of greater surgeon-perceived similarity and to assess associations of perceived similarity with evaluation of parent characteristics.

RESULTS

Most parents were women (n = 38, 84%), whereas surgeons were primarily men (n = 7, 54%). Of 45 parents, 23 (51%) were non-White, whereas only 4 of 13 clinicians (31%) were non-White. Mean perceived similarity score was 21.7 for parents (range, 10-24) and 18.2 for surgeons (range, 10-24). There was no difference in parent-perceived similarity based on race (White vs non-White parents, mean [SD] = 22.3 [3.4] vs 21.1 [3.0]; P = .26). Surgeons perceived greater similarity with White parents (odds ratio = 4.78; 95% CI, 1.02-22.54; P = .04) and parents with higher income (odds ratio = 11.84; 95% CI, 1.32-106.04; P = .03). Greater perceived similarity by the surgeons was associated with more positive assessments of parent personality characteristics.

CONCLUSION

Surgeons perceived similarity more commonly with White parents, while parents' perception of similarity to surgeons was uniform regardless of parent race. Elucidating biases of surgeons may help to tailor interventions promoting culturally competent, equitable communication and decision making for elective surgery.

Towards a Comprehensive Theory of Love: The Quadruple Theory

Scholars across an array of disciplines including social psychologists have been trying to explain the meaning of love for over a century but its polysemous nature has made it difficult to fully understand. In this paper, a quadruple framework of attraction, resonance or connection, trust, and respect are proposed to explain the meaning of love. The framework is used to explain how love grows and dies and to describe brand love, romantic love, and parental love. The synergistic relationship between the factors and how their variations modulate the intensity or levels of love are discussed.

Seeing beyond political affiliations: The mediating role of perceived moral foundations on the partisan similarity-liking effect

Decades of research have demonstrated that we like people who are more similar to us. The present research tested a potential mechanism for this similarity-liking effect in the domain of politics: the stereotype that people's political orientation reflects their morals. People believe that Democrats are more likely to endorse individualizing morals like fairness and Republicans are more likely to endorse binding morals like obedience to authority. Prior to the 2016 election, American participants (N = 314) viewed an ostensible Facebook profile that shared an article endorsing conservative ideals (pro-Trump or pro-Republican), or liberal ideals (pro-Clinton or pro-Democrat). Participants rated the favorability of the profile-owner, and completed the Moral Foundations Questionnaire for the profile-owner and themselves. As predicted, participants liked the profile-owner more when they shared political beliefs, and used political stereotypes to infer the moral foundations of the profile-owner. Additionally, the perceived moral foundation endorsement of the profile owner differentially mediated the relationship between the ideology and evaluations of the profile owner based on the party affiliation of the participant: perceived individualizing foundations mediated the relationship for Democratic participants and perceived binding foundations mediated the relationship for Republican participants. In other words, people liked their in-group members more because they thought that the profile-owner endorsed a specific type of morals. In Study 2 (N = 486), we ruled out the potential explanation that any political stereotype can account for the similarity-liking effect, replicating the results of Study 1 even when controlling for perceptions of other personality differences. Taken together, these studies highlight that there may be something unique about the perceived type of morality of political in-group and out-group members that may be contributing to the similarity-liking effect in politics.
