- The "above-average effect" is the phenomenon that people tend to judge themselves above average on desirable traits. Based on social identity theory, we propose that a "below-average effect" may arise when individuals rate themselves and the average ingroup member on traits stereotypically associated with the ingroup. In two studies, Republican and Democrat participants rated themselves and the average political ingroup member on possession of desirable traits related to warmth and competence. Current political stereotypes in America associate the former dimension with Democrats and the latter with Republicans. Consistent with our hypothesis, the above-average effect was moderated by political group and dimension in interaction. In particular, Democrats rated themselves below the average Democrat on warmth and Republicans rated themselves below the average Republican on competence.

A New Look at Individual Differences in Perceptions of Unfairness : The Theory of Maximally Unfair Allocations in Multiparty Situations
- 2015

- Previous research has demonstrated that unfairness judgments of resource allocations become more complex when there are more than two recipients. In order to explain some of this complexity, we propose a set of psychological mechanisms that may underlie four different choices of maximally unfair resource allocations (MUA): Self-Single-Loser, Self-One-Loser-of-Many, Self-Single-Winner, and Self-One-Winner-of-Many. From this psychological theory, several predictions are derived and tested in vignette studies involving a total of 708 participants recruited online using MTurk. As predicted by our theory, (1) choices of MUA where there is a single loser were much more common when the allocated resource was of negative rather than positive valence, and (2) the amount of egoistic bias individuals exhibited when judging the unfairness in receiving a small rather than a large share in a non-extreme multi-party allocation was predicted by their choices of MUA. These findings suggest that an individual’s choice of MUA reveals some generally relevant principles of how unfairness is perceived in multi-party allocations. This opens up new lines of inquiry, especially regarding research on social dilemmas and social value orientation.

A Note on the Exact Expected Length of the kth Part of a Random Partition
- 2010

Ingår i: Integers. - 1867-0652. ; 10, s. 309-311

Tidskriftsartikel (refereegranskat)abstract
- Kessler and Livingstone proved an asymptotic formula for the expected length of the largest part of a partition drawn uniformly at random. As a first step they gave an exact formula expressed as a weighted sum of Euler's partition function. Here we give a short bijective proof of a generalization of this exact formula to the expected length of the kth part.

An Exponential Limit Shape of Random q-proportion Bulgarian Solitaire
- 2018
-
Ingår i: Integers. - 1553-1732. ; 18

Tidskriftsartikel (refereegranskat)abstract
- We introduce pn-random qn-proportion Bulgarian solitaire (0 < pn, qn ≤ 1), playedon n cards distributed in piles. In each pile, a number of cards equal to the propor-tion qn of the pile size rounded upward to the nearest integer are candidates to bepicked. Each candidate card is picked with probability pn, independently of othercandidate cards. This generalizes Popov’s random Bulgarian solitaire, in whichthere is a single candidate card in each pile. Popov showed that a triangular limitshape is obtained for a fixed p as n tends to infinity. Here we let both pn and qnvary with n. We show that under the conditions q2npnn/log n → ∞ and pnqn → 0 asn → ∞, the pn-random qn-proportion Bulgarian solitaire has an exponential limitshape.

Appropriateness ratings of everyday behaviors in the United States now and 50 years ago
- 2023
-
Ingår i: Frontiers in Psychology. - : Frontiers Media S.A.. - 1664-1078. ; 14
-
Tidskriftsartikel (refereegranskat)abstract
- Introduction: A crucial aspect of social norms pertains to determining which behaviors are considered appropriate. Here we consider everyday behaviors. Some everyday behaviors are rated as more appropriate than others, and ratings of the appropriateness of a given behavior may vary over time. The objective of this study is to elucidate the reasons behind variation in appropriateness ratings of everyday behaviors in the United States. Our theory focuses on how the evaluation of the appropriateness of a behavior is influenced by its potential for externalities and internalities, and how this influence may cause a change in norms over time.Method: Employing a preregistered design, we asked American participants to rate 37 different everyday behaviors based on their appropriateness in a range of common situations, as well as their potential negative externalities (e.g., being loud, being aggressive, taking up space) and positive internalities (e.g., pleasurability). Changes over time were calculated as the difference between mean ratings obtained in this study and ratings of the same behavior in a similar study conducted 50 years ago.Results: As expected, overall appropriateness ratings of everyday behaviors are associated both with their externalities and their internalities, so that the least appropriate behaviors tend to have considerable potential for negative externalities and little potential for positive internalities. Moreover, behaviors that have considerable potential for negative externalities are perceived as less appropriate now than 50 years ago.Discussion: By describing how social norms for everyday behaviors depend on the externalities and internalities of behaviors, this study contributes to theories about the emergence and change of social norms.

Are people really conformist-biased? : An empirical test and a new mathematical model
- 2009
-
Ingår i: Journal of Evolutionary Psychology. - 0737-4828. ; 7:1, s. 5-21
-
Tidskriftsartikel (refereegranskat)abstract
- According to an influential theory in cultural evolution, within-group similarity of culture is explained by a human conformist-bias, which is a hypothesized evolved predisposition to preferentially follow a member of the majority when acquiring ideas and behaviours. However, this notion has little support from social psychological research. In fact, a major theory in social psychology (Latan and Wolf (1981) argues for what is in effect a nonconformist-bias: by analogy to standard psychophysics they predict minority sources of influence to have relatively greater impact than majority sources. Here we present a new mathematical model and an experiment on social influence, both specifically designed to test these competing predictions. The results are in line with nonconformism. Finally, we discuss within-group similarity and suggest that it is not a general phenomenon but must be studied trait by trait.

Asymmetric equilibria in dynamic two-sided matching markets with independent preferences
- 2008

- A fundamental fact in two-sided matching is that if amarket allows several stable outcomes, then one is optimal for all men in the sense that no man would prefer another stable outcome.We study a related phenomenon of asymmetric equilibria in a dynamic market where agents enter and search for a mate for at most n rounds before exiting again. Assuming independent preferences, we find that this game has multiple equilibria, some of which are highly asymmetric between sexes. We also investigate how the set of equilibria depends on a sex difference in the outside option of not being mated at all.

Autism-spectrum traits predict humor styles in the general population
- 2013

Tidskriftsartikel (refereegranskat)abstract
- Previous research shows that individuals with Asperger syndrome or high-functioning autism tend to have impaired processing of humor and laugh at things that are not commonly found funny. Here the relationship between humor styles and the broader autism phenotype was investigated in a sample of the general population. The autism-spectrum quotient (AQ) and the humor styles questionnaire (HSQ) were administered to six hundred US participants recruited through an Internet-based service. On the whole, high scores on AQ were negatively related to positive humor styles and unrelated to negative humor styles. However, AQ subscales representing different autism-spectrum traits exhibited different patterns. In particular, the factor poor mind-reading was associated with higher scores on negative humor styles and the factor attention to detail was associated with higher scores on all humor styles, suggesting a more nuanced picture of the relationship between autism-spectrum traits and humor.
