Stigmas are prejudices or discrimination against people based on qualities that vary from the norm, such as a physical or mental illness, disability, sexuality, race, or one of many other personal characteristics. The harm caused by stigmatisation has made understanding the causes and potential solutions a vital area of study in psychology and public health. One of the major focuses of ongoing research is understanding the factors that determine whether a particular characteristic becomes stigmatised, and if so how the stigma might be eliminated. Previous research has found that for disease-based stigmas, the contagiousness, course, and disruptiveness of a disease can be influential. Another key determinant is the perceived cause of the stigmatised condition or characteristic. In a landmark study, Weiner et al. (1988) reported that attributes based on physical health were more likely to be perceived as being uncontrollable, stable and irreversible, prompting feelings of sympathy without anger or judgment. On the other hand, attributes related to mental health and behaviour were more likely to be regarded as controllable and reversible, prompting lack of sympathy coupled with feelings of anger and negative judgement. In a second experiment, they also found that manipulating the perception of controllability can modify emotional responses and judgments – for some stigmas (but not others), providing participants with information that a particular characteristic was controllable vs. uncontrollable was found to increase or decrease negative attributions, respectively.

 

In the current study, Yeung and Feldman (2022) propose to replicate Experiment 2 from Weiner et al. (1988) in a large online sample. In particular, they plan to ask how the source of a stigma is related to perceived controllability and stability, emotional reactions, and willingness to help. They also propose a range of extensions, including the inclusion of additional stigmas that have become relevant since the original study was published over 30 years ago.

Anthropomorphism is a widespread phenomenon in which people instil non-human entities or objects with human-like characteristics, such as motivations, intentions, and goals. Although common, the tendency to anthropomorphise varies between people, and a growing body of psychological research has examined the importance of various individual differences. One major theoretical account of anthropomorphism (Epley et al. 2007) suggests that sociality motivation – the drive to establish social relationships – is a key moderator of the phenomenon. In support of this account, some evidence suggests that people who experience greater loneliness (a proposed marker of sociality motivation) are more likely to anthropomorphise. In an influential series of studies, Epley et al. (2008) found that anthropomorphism and loneliness were positively correlated and that inducing participants experimentally to feel more lonely led to greater anthropomorphism. Later studies, however, produced more mixed results, particularly concerning the effectiveness of the experimental interventions.

 

In the current study, Elsherif et al. (2022) propose a partial replication of Epley et al. (2008), focusing on the correlational relationship between anthropomorphism and loneliness, with extensions to examine free will beliefs, anthropomorphism for supernatural beings (in addition to objects/gadgets), and the extent to which participants judged objects/gadgets to be controllable.

Does being good free people up to be bad? A large literature in social psychology suggests that it might, with evidence that “moral licensing” gives people a perception that actions deemed morally questionable, or socially undesirable, will be tolerated more readily if they have demonstrated a past history of praiseworthy, moral behaviour. In a formative study, Monin and Miller (2001) reported that having a track record of moral credentials as being nonprejudiced (e.g. non-sexist or non-racist) increased the willingness of participants to later express a prejudiced attitude. For example, in their Study 2 they found that participants who built up their moral credit by selecting a Black woman in a hypothetical recruitment task were then more willing to then prefer a White man for a second job, compared to participants who did not have the opportunity to initially recommend a Black woman. These results have prompted a burgeoning literature on moral licensing, albeit one that is mixed and has been found to exhibit substantial publication bias.

 

In the current study, Xiao et al. (2023) propose a large online replication of Study 2 in Monin and Miller (2001), asking whether previous moral behaviours that furnish participants with moral credentials make them more likely to then engage in morally questionable behaviours. The authors will also extend earlier work by testing whether moral credentials license immoral behaviours more effectively in the same domain (e.g. within sex) than in a different domain (e.g. across sex and race), asking whether there is a negative relationship between expression of prejudice and trait reputational concern (fear of negative evaluation), and whether moral credentials attenuate any such observed relationship.

The sunk cost fallacy is a cognitive bias in which people persist with a decision that is no longer optimal because of previous resources they have invested (now considered to be spent or “sunk”). Most of us will have heard sunk costs reflected in the saying “throwing good money after bad”, but sunk costs can, in theory, occur more broadly, whether for money, time or any other resource-limited investment. The sunk cost effect for money has been widely studied and appears robust; in contrast, the sunk cost effect for time is more uncertain, and is potentially moderated by the age of respondents (and likely resource availability), the fact that time is irreplaceable, and the tendency for people to account for time less easily than they do for money. In an impactful study, Soman (2001) found that the sunk cost effect for time was indeed weaker than for money, although this finding has not been widely replicated.

 

In the current study, Petrov et al. (2023) propose a replication of three studies from Soman (2001), asking whether sunk costs are weaker for time than for money, and then testing whether the relative absence of a sunk time cost arises from the inability of participants to account for time or due to more rational beliefs in the evaluation of past time investments.

A convergence of evidence suggests that early life adversity may cause dysfunction in opioid-sensitive reward systems. Childhood adversity is associated with opioid use, potentially by altering reward and motivation networks, and experimental models in animals have found that early life adversity increases and consolidates opioid seeking behaviours. Further, in a recent controlled experiment, Carlyle et al. (2021) found that opioid administration produced stronger positive responses, and weaker negative responses, in adults with a history of childhood abuse and neglect.

 

In the current study, Carlyle et al. seek to test the generalisability of these previous findings in a pre-operative clinical setting. Using partially observed data from an existing cohort study (N=155), the authors will test whether patients with greater experience of childhood trauma in turn exhibit a larger mood boost and express greater subjective pleasure following opioid administration. Although not a randomised experimental design, this study provides the opportunity to examine the relationship between opioid response and history of childhood adversity in a naturalistic setting, and thus has the potential to either support or cast doubt on the theory that adversity elevates risk of opioid addiction by altering sensitivity to subjectively pleasurable effects.
