Examining the Typologies of Change in Support for the Civil Union Act and Same-Sex Marriage Over Fourteen Years (2009–2023)
Deprivation or Dominance? Examining the Psychological Antecedents of Historical Negation Among Europeans Over Time
Although historical negation—the ideologically-based denial of the contemporary relevance of colonial injustices—sustains inequities between settler colonisers and Indigenous peoples, few studies explore the psychological processes underlying historical negation among settler colonisers. In this pre-registered study, we examine whether perceived group-based relative deprivation (GRD) fosters historical negation among New Zealand Europeans. To do …
The Cambridge Handbook of the Psychology of Violent Extremism
Psychology, with its dedication to understanding human behavior and its complexities, is a key part in comprehending the underpinnings of violent extremism. This comprehensive resource encompasses all major psychological frameworks related to violent extremism, making it essential reading for scholars, practitioners, policymakers, and students determined to enact positive change in this critical area. This handbook provides a state-of-the-art ove…
Perceived Relative Deprivation Across the Adult Lifespan: An Examination of Aging and Cohort Effects
Despite being a core psychological construct for over 70 years, research has yet to examine how perceptions of deprivation relative to other individuals and/or groups develop across adulthood. As such, this preregistered study uses cohort-sequential latent growth modeling to examine changes in individual- and group-based relative deprivation (IRD and GRD, respectively) across the adult lifespan. Across 10 annual assessments of a nationwide random…
Psychological Entitlement and Relative Deprivation Have Reciprocal Cross-lagged Associations for Both Structurally Advantaged and Disadvantaged Groups
Although relative deprivation theory argues that individual differences influence the degree to which people perceive themselves (IRD) or their group (GRD) as unfairly disadvantaged, few studies directly assess the psychological motivators underlying perceptions of injustice. We address this oversight by examining the relationships between psychological entitlement and relative deprivation using twelve annual waves of a nationwide random panel sa…
Are men toxic? A person-centered investigation into the prevalence of different types of masculinity in a large sample of New Zealand men
Despite being frequently discussed in both mainstream discourse and academic scholarship, little empirical work defines “toxic masculinity.” We address this oversight by estimating the prevalence of men’s distinct response patterns to eight indicators of problematic masculinity: gender identity centrality, sexual prejudice, disagreeableness, narcissism, hostile sexism, benevolent sexism, opposition to domestic violence prevention initiatives, and…
Changes in support for free speech and hate speech restrictions: Cohort, aging, and period effects among ethnic minority and majority group members
How do attitudes toward free speech and hate speech restrictions change across the adult lifespan? The current research utilizes data from five annual waves of longitudinal data from 2019 to 2024 ( N > 50,000) to examine the extent to which cohort, period, and age effects contribute to changes in attitudes toward free speech and hate speech among ethnic majority and minority group members during a period of changing societal norms about freedom o…
A Naturalistic Test of Minority Stress Theory: Examining Social and Psychological Well-Being Trends Across Heterosexual and Sexual Minority Adults from 2009 to 2022
Minority stress theory suggests that shifts toward egalitarianism should reduce well-being disparities between heterosexual people and lesbian, gay, bisexual, and other sexual minorities (LGB+ people). However, few studies have examined well-being trends in these groups over periods of social change. We addressed this issue directly using a large nationwide random sample of New Zealand adults over thirteen years (from 2009 to 2022; N total = 72,7…
Examining the Antecedents, Prevalence and Trajectories of Reactionary Collective Action Intentions Among Europeans Over Time
Reactionary movements—movements that effectively increase inequality by advancing the rights of structurally advantaged groups—are of increasing concern in contemporary politics. Yet few studies assess support for these movements over time. We address this oversight in two studies examining reactionary collective action intentions over 9 years in a nationwide sample of New Zealand Europeans ( N total = 54,561). Random intercept cross‐lagged panel…
Examining the indirect effect of income on well‐being via individual‐based relative deprivation: Longitudinal mediation with a random intercept cross‐lagged panel model
Although the positive relationship between income and well‐being is well established, the psychological mechanisms underlying this process are less understood. One underexplored explanation is that objective wealth (or lack thereof) fosters relative comparisons, which, in turn, predicts well‐being. Extant work has, however, mostly focused on objective indicators of relative deprivation rather than on how people perceive their societal status. We …
Opposing Misperceptions of Wealth: Liberals Overestimate Their Neighborhoods’ Wealth in Wealthier Neighborhoods While Conservatives Overestimate Their Neighborhoods’ Wealth in Poor Neighborhoods
Although perceptions of wealth are shaped by people’s social environment and ideological beliefs, few studies integrate these two perspectives. We address this oversight by examining the association between participants’ actual and estimated average neighborhood household income and whether political orientation moderates this relationship. Using a large, nationwide random sample of New Zealand adults ( N = 14,853), our results reveal that both l…
Status-Based Asymmetries in Relative Deprivation During the Covid-19 Pandemic
The COVID-19 pandemic has amplified existing inequalities by disproportionately affecting marginalized groups, which should differentially affect perceptions of, and responses to, inequality. Accordingly, the present study examines the effects of the pandemic on feelings of individual- and group-based relative deprivation (IRD and GRD, respectively), as well as whether these effects differ by ethnicity. By comparing matched samples of participant…
My Body, My Choice? Examining the Distinct Profiles Underlying Attitudes Toward Abortion and Covid-19 Mandates
Protestors recently repurposed the abortion rights’ mantra, “my body, my choice,” to oppose COVID-19 mandates. But do those who oppose public health mandates fully support the right to choose? We answer this question by using exploratory analyses to identify the unique response patterns underlying support for abortion and COVID-19 mandates in random samples from the United States (Study 1; N = 2,331) and New Zealand (Study 2; N = 33,310). Latent …
Ethnic identity centrality across the adult lifespan: Aging, cohort, and period effects among majority and minority group members
8,325) group members in New Zealand to examine changes in ethnic identity centrality using cohort-sequential latent growth modeling. This approach helps to identify changes in mean levels of ethnic identity centrality over time and whether such changes are driven by aging, cohort, and/or period effects. Our data reveal that, among both ethnic majority and ethnic minority individuals, changes in ethnic identity centrality were informed by a combin…
Social media use does not increase individual-based relative deprivation: Evidence from a five-year RI-CLPM
Although a growing literature demonstrates that social media usage fosters upward social comparisons, the potential for social media use to elicit perceptions of unjust disadvantage relative to others remains unexplored. We address this oversight by leveraging six annual waves of a nationwide random probability sample of adults (ages 18–99; N = 62,017) to examine the average between- and within-person associations between social media use and fee…
Asymmetries in responses to group-based relative deprivation: The moderating effects of group status on endorsement of right-wing ideology
Feelings of group-based relative deprivation (GRD) motivate collective responses to defend the ingroup. As such, there may be status-based asymmetries in the associations GRD has with ideologies that perpetuate inequality—namely, right-wing authoritarianism (RWA) and social dominance orientation (SDO). Study 1 examined this hypothesis using a national sample of adults ( N = 41,007) and revealed that the correlations GRD had with RWA and SDO were …
Examining the between‐ and within‐person effects of relative deprivation: Results from a 7‐year longitudinal panel sample
Despite the extensive literature on relative deprivation theory, few studies have examined the longitudinal effects of individual‐ and group‐based relative deprivation (IRD and GRD, respectively) on individual‐ and group‐based outcomes, nor has research investigated the between‐person and within‐person effects of these constructs. Using two random intercept cross‐lagged panel models, we address these oversights by estimating the between‐person an…
Fixed or Fluid? Sexual Identity Fluidity in a Large National Panel Study of New Zealand Adults
Sexual orientation has been defined as an enduring aspect of the self, but emerging evidence reveals that people's sexual attractions, behaviors, and identities can shift over time. To examine this possibility, we present a large longitudinal analysis of sexual orientation identity fluidity among New Zealand adults ( N total = 45,856; age = 18-99; lesbian, gay, bisexual, and other sexual minority (LGB+) n s = 746-3,387). Over seven years, 5.7% of…
