While hope is related to greater meaning in life, how hope promotes meaning has been under-explored. One pathway may be that hope motivates behaviors that help us reach our hoped-for goal, which in turn increases a sense of meaning. The current studies test this process in the domain of health. Two correlational studies show that hope for one’s health promotes related behaviors and in turn, greater meaning. Study 1 examines this relation under the context of the COVID-19 pandemic, which posed a large threat to meaning, thus, hope was a particularly relevant resource for meaning during this time. Study 2 aimed to examine this relation in domains widely applicable to everyday life: exercise and nutrition. In Study 3, participants randomly assigned to write about being hopeful (vs. hopeless) about their health reported greater healthy eating/exercising intentions, which in turn, led to greater meaning. The studies inform how working towards one’s hoped-for goals can be impactful on meaning in life.

We investigate why individuals commonly perceive time as passing quickly when reflecting on past periods of their lives. A traditional cognitive account proposes that routine experienced during a period decreases the number of memorable events, making that period appear short in retrospect. A motivational account derived from self-determination theory proposes that a period remembered as lacking self-determined growth feels unsatisfying or wasted, and thus seems to pass quickly. Two exploratory studies ( N = 999) did not consistently support these accounts, although in Study 2 remembered routine predicted faster perceived pace, as hypothesized. Contrary to our motivational account, remembered growth positively, rather than negatively, predicted pace. Interpreting this unexpected finding, we conducted two pre-registered studies ( N = 965) exploring how satisfaction with, and nostalgic longing for, periods of growth contribute to the perception of time passing quickly. Our findings have implications for encouraging productive responses to the subjective pace of life.

Previous research points to social/affiliative needs as playing an important role in orienting people towards conspiratorial thinking. Yet no research to date has compared the relative contribution of different forms of subjective interpersonal isolation to general conspiracist ideation (CI). Four studies (N = 2,452) compare the associations between three forms of subjective isolation (loneliness, existential isolation, alienation/anomie) and CI. Results from Studies 1–3 indicate that existential isolation and alienation, but not loneliness, independently predict higher CI over and above other relevant predictors. Study 4 found that after controlling for relevant covariates, only anomie predicted CI. Exploratory analyses revealed that unique effects of existential isolation on CI emerged when the breakdown of the leadership subdimension of anomie was excluded from the model. Implications of the four studies are discussed.

Objective: The present research examines how different forms of subjective isolation predict COVID-19 vaccine hesitancy and resistance with two online studies conducted in the U.S. Methods: Study 1 (n = 695), conducted before COVID-19 vaccines were available, tested if different forms of subjective isolation predicted lower trust in potential COVID-19 vaccines. Study 2 (n = 674), conducted almost a year after COVID-19 vaccines were available, tested if different forms of subjective isolation predicted not being vaccinated. Results: In Study 1, existential isolation and alienation predicted lower trust in potential COVID-19 vaccines, while loneliness did not. In Study 2, existential isolation and alienation, but not loneliness, predicted not getting vaccinated. Conclusion: Existential isolation and alienation are associated with negative attitudes and behavior towards vaccines and may contribute to decreased participation in public health-related behaviors.

Objective Prior work suggests perceived COVID-19-related threat and existential isolation (EI) would be associated with greater anxiety and depression, worse subjective health and well-being, and lower hope. However, it was unclear whether such concerns might have additive effects (no interaction, two independent main effects) or interact (one effect modifies the other). Method Two studies collected data via MTurk during the COVID-19 pandemic. Study 1 (N = 110) measured perceived COVID19-related threat, EI, anxiety and depression, subjective well-being, and hope. Study 2 (N = 2,673) measured perceived COVID19-related threat, EI, anxiety, subjective health, and hope. Results In general, perceived COVID19-related threat and EI were associated with anxiety and depression, worse subjective health and well-being, and reduced hope. On one outcome (hope, Study 2), an interaction was observed: perceived threat was associated with lower hope among those with high EI, but higher hope among those with low EI. However, on most outcomes (6 of 7), across both studies, additive effects were observed: greater cumulative existential stress (perceived COVID-19-related threat, EI) was associated with worse anxiety and depression, subjective health and well-being, and hope. Conclusion Discussion highlights theoretical considerations, practical implications, and the therapeutic value of addressing existential concerns in mental health.

We propose that awe has multifaceted relations with existential isolation, a feeling of separation between the self and others or the world. Three studies examined the relation between awe and existential isolation via feelings of small self (vastness, self-size, self-perspectives) and a sense of connectedness. Awe (vs. a control topic) was induced either using virtual reality (Study 1) or a recall task (Studies 2 and 3) and was indirectly associated with higher and lower levels of existential isolation through differing pathways. Awe was associated with lower feelings of existential isolation via an increased sense of vastness, which in turn predicted greater connectedness; whereas awe was associated with higher feelings of existential isolation via increased sense of feeling small, which in turn predicted lower connectedness. This work advances understanding of the complex nature of awe-revealing its competing effects on the self and the social connectedness pathways through which awe can influence existential isolation.

In the United States, police are becoming increasingly militarized. Whereas the racialized nature of police militarization has been documented, the relationship between racial prejudice and police militarization is less understood. We assessed the link between racial prejudice against Black and Native Americans and police militarization at individual and regional levels. Study 1 ( N = 765) recruited a nationally representative sample of White Americans and found a positive association between racial prejudice and support for police militarization. Study 2 ( N = 3,129,343) sourced regional aggregates of prejudice among White Americans from Project Implicit and policing data from the Defense Logistics Agency and found that police departments in states higher in prejudice acquired greater amounts of militarized equipment. Together, these studies demonstrate that, in terms of attitudes and policies, racial prejudice predicts police militarization.

An apparent phenomenological divide between majority and minoritized groups exists in contemporary America in terms of feelings of social connection. Drawing on recent findings relating to existential isolation (i.e., the sense that one is alone in one’s subjective experience), three studies compare these feelings toward one’s in-group and out-group. Study 1 assesses whether Black and White participants vary in their self-reported existential isolation when referencing their own or another racial group. Results reveal Black Americans feel as though other Black Americans share their perceptions more than do White Americans. In contrast, White Americans report similarly shared perceptions by both racial groups. Study 2 (preregistered) assessed these effects with a concealable identity: sexual orientation. Study 3 further replicates these effects and finds effects among Black Americans to significantly differ from a neutral control condition. Implications and future directions for epistemic (in)validation are discussed.

Stay-at-home orders issued to combat the growing number of infections during the coronavirus pandemic in 2020 had many psychological consequences for people including elevated stress, anxiety, and difficulty maintaining meaning in their lives. The present studies utilized cross-sectional designs and were conducted to better understand how social media usage related to people’s subjective isolation (i.e., social loneliness, emotional loneliness, and existential isolation) and meaning in life (MIL) during the early months of the pandemic within the United States. Study 1 found that general social media use indirectly predicted higher MIL via lower existential isolation and social isolation. Study 2 replicated these patterns and found that social media use also predicted lower MIL via higher emotional loneliness, and that the aforementioned effects occurred with active, but not passive, social media use. Findings suggest social media use may be a viable means to validate one’s experiences (i.e., reduce existential isolation) during the pandemic but may also lead to intensified feelings concerning missing others (i.e., increased emotional loneliness). This research also helps to identify potential divergent effects of social media on MIL and helps to clarify the relationships among varying types of subjective isolation.
