- Decomposing spatial effects of state-level health outcomes: a methodological demonstration and re-analysisPublication . Gruda, Dritjon; Hanges, Paul; McCleskey, Jim A.While spatial autoregressive (SAR) models are increasingly used in population-level psychological studies, researchers often overlook the crucial step of parsing effects into direct, indirect and total impacts, a standard practice in spatial econometrics. In this paper, we demonstrate the necessity of this practice by re-analyzing Gruda et al.'s (2024) U.S. Dark-Triad and health dataset with heteroskedasticity-robust SAR models and full impact decomposition, revealing significant changes. The previously observed direct protective effect of state-level narcissism on hypertension mortality disappeared when accounting for interstate spillovers. Conversely, the association with lower cancer prevalence and depression strengthened. Several health-behaviour findings reversed direction, indicating naïve regressions conflated within- and between-state effects. Machiavellianism and psychopathy coefficients also shifted. These results demonstrate that spatial spillovers can dilute, negate or reverse local effects, cautioning against policy inferences based solely on direct estimates.
- Every vote you make: attachment and state culture predict bipartisanship in U.S. CongressPublication . Gruda, Dritjon; Hanges, Paul; Mikneviciute, Eimante; Karanatsiou, Dimitra; Vakali, AthenaDo politicians' relational traits predict their bipartisan voting behavior? In this paper, we empirically test and find that relational individual dispositions, namely attachment orientations and conformity to cultural norms, can predict the bipartisan voting behavior of politicians in the United States House of Representatives and Senate. We annotated politicians' tweets using a machine learning approach paired with archival resources to obtain politicians' home-state looseness-tightness culture scores. Anxiously-attached politicians were less likely to be bipartisan than avoidantly-attached individuals. Bipartisan voting behavior was less likely in politicians whose home state was less tolerant of deviation from cultural norms. We discuss these results and possible implications, such as the preemptive assessment of politicians' bipartisanship likelihood based on attachment and state cultural pressure to adhere to group norms.
- Mirror, mirror on the wall, who's the healthiest of them all – The surprising role of narcissism in state-level health outcomesPublication . Gruda, Dritjon; Hanges, Paul; McCleskey, JimThis study investigates narcissism's role in state-level health outcomes across the U.S. While often seen as maladaptive, narcissism's adaptive aspects, like self-enhancement, might promote better health. Analyzing data from 4,230 participants in 38 states, we explore the link between dark triad traits (narcissism, Machiavellianism, psychopathy) and health outcomes. States with higher narcissism had lower obesity and depression rates, and a lower likelihood of heart failure and hypertension deaths. However, these states reported less sleep and higher demand for plastic surgeons. This study is the first to provide a nuanced understanding of the complex interplay between dark triad traits and health on the state level, with significant implications for public health policies and interventions.
- Turn down for watt: community fit and thermal comfort habituation predict average household heating energy consumptionPublication . Gruda, Dritjon; Hanges, PaulLowering average household heating energy consumption plays a pivotal role in addressing climate change and has been central to policy initiatives. Strategies proposed so far have included commitments, incentives/ disincentives, feedback, and social norms. Yet, findings so far have been mixed and fail to explain the mechanism that drives energy conservation behavior. Using a sample of 2,128 participants across the United States, we collected survey data matched with archival temperature data to investigate the influence of past experiences on current energy conservation behaviors. Our findings indicate that childhood home temperatures significantly predict current home temperature settings. Importantly, community fit moderated this relationship. Individuals with high community fit were more likely to align their home temperature settings to those of their community. These insights not only shed light on the underlying mechanisms driving energy consumption behavior but also suggest that fostering a sense of community fit might be a more effective strategy for promoting sustainable energy practices.
