Conservatives and liberals have similar physiological responses to threats.

ABSTRACT: About a decade ago, a study documented that conservatives have stronger physiological responses to threatening stimuli than liberals. This work launched an approach aimed at uncovering the biological roots of ideology. Despite wide-ranging scientific and popular impact, independent laboratories have not replicated the study. We conducted a pre-registered direct replication (n?=?202) and conceptual replications in the United States (n?=?352) and the Netherlands (n?=?81). Our analyses do not support the conclusions of the original study, nor do we find evidence for broader claims regarding the effect of disgust and the existence of a physiological trait. Rather than studying unconscious responses as the real predispositions, alignment between conscious and unconscious responses promises deeper insights into the emotional roots of ideology.

Conservatives Report Greater Meaning in Life than Liberals.

Project description:Conservatives report greater life satisfaction than liberals, but this relationship is relatively weak. To date, the evidence is limited to a narrow set of well-being measures that ask participants for a single assessment of their life in general. We address this shortcoming by examining the relationship between political orientation and well-being using measures of life satisfaction, affect, and meaning and purpose in life. Participants completed well-being measures after reflecting on their whole life (Studies 1a, 1b, and 2), at the end of their day (Study 3), and in the present moment (Study 4). Across five studies, conservatives reported more meaning and purpose in life than liberals at each reporting period. This finding remained significant after adjusting for religiosity and was usually stronger than the relationships involving other well-being measures. Finally, meaning in life was more closely related to social conservatism than economic conservatism.

Dining with liberals and conservatives: The social underpinnings of food neophobia.

Project description:Although food and politics seem to be distant domains, socio-political ideology and food neophobia (i.e., reluctance to eat unfamiliar food) may be related. Conservatives' high threat sensitivity and the inherently threatening nature of novel foods (the existential explanation), along with conservatives' negative attitudes toward minority outgroups (e.g., foreigners) and the role of the latter in introducing novel foods to a culture (the social explanation), led us to expect that socio-political ideology would predict food neophobia over and above their common roots. Across two correlational and two experimental studies (N = 627), socio-political ideology emerged as a strong predictor of food neophobia. In addition, the findings did not support the existential explanation, while confirming the social explanation of the ideology-food neophobia link: Conservatives seem more neophobic than liberals not because of their higher threat sensitivity but rather because they hold more negative attitudes toward foreigners who are associated with those foods.

Conservatives' Moral Foundations Are More Densely Connected Than Liberals' Moral Foundations.

Project description:We use network psychometrics to map a subsection of moral belief systems predicted by moral foundations theory (MFT). This approach conceptualizes moral systems as networks, with moral beliefs represented as nodes connected by direct relations. As such, it advances a novel test of MFT's claim that liberals and conservatives have different systems of foundational moral values, which we test in three large datasets (NSample1 = 854; NSample2 = 679; NSample3 = 2,572), from two countries (the United States and New Zealand). Results supported our first hypothesis that liberals' moral systems show more segregation between individualizing and binding foundations than conservatives. Results showed only weak support for our second hypothesis, that this pattern would be more typical of higher educated than less educated liberals/conservatives. Findings support a systems approach to MFT and show the value of modeling moral belief systems as networks.

Liberals lecture, conservatives communicate: Analyzing complexity and ideology in 381,609 political speeches.

Project description:There is some evidence that liberal politicians use more complex language than conservative politicians. This evidence, however, is based on a specific set of speeches of US members of Congress and UK members of Parliament. This raises the question whether the relationship between ideology and linguistic complexity is a more general phenomenon or specific to this small group of politicians. To address this question, this paper analyzes 381,609 speeches given by politicians from five parliaments, by twelve European prime ministers, as well as speeches from party congresses over time and across countries. Our results replicate and generalize earlier findings: speakers from culturally liberal parties use more complex language than speakers from culturally conservative parties. Economic left-right differences, on the other hand, are not systematically linked to linguistic complexity.

Why are conservatives less concerned about the coronavirus (COVID-19) than liberals? Comparing political, experiential, and partisan messaging explanations.

Project description:Given research revealing conservatives are more sensitive to disease threat, it is curious that U.S. conservatives were less concerned than liberals with the COVID-19 pandemic. Across four studies that spanned almost ten months throughout the pandemic, we evaluated three potential reasons why conservatives were less concerned: (1) Motivated Political reasons (conservatives held COVID-specific political beliefs that motivated them to reduce concern), (2) Experiential reasons (conservatives were less directly affected by the outbreak than liberals), and (3) Conservative Messaging reasons (differential exposure to/trust in partisan conservative messaging). All four studies consistently showed evidence that political (and not experiential or partisan messaging) reasons more strongly mediated conservatives' lack of concern for COVID-19. Additional analyses further suggested that while they did not serve as strong mediators, experiential factors provided a boundary condition for the conservatism➔perceived threat relationship. These data on over 3000 participants are consistent with a new model of the ideology-disease outbreak interface that can be applied to both the ongoing pandemic and future disease outbreaks.

Moving Morality Beyond the In-Group: Liberals and Conservatives Show Differences on Group-Framed Moral Foundations and These Differences Mediate the Relationships to Perceived Bias and Threat.

Project description:Moral foundations research suggests that liberals care about moral values related to individual rights such as harm and fairness, while conservatives care about those foundations in addition to caring more about group rights such as loyalty, authority, and purity. However, the question remains about how conservatives and liberals differ in relation to group-level moral principles. We used two versions of the moral foundations questionnaire with the target group being either abstract or specific ingroups or outgroups. Across three studies, we observed that liberals showed more endorsement of Individualizing foundations (Harm and Fairness foundations) with an outgroup target, while conservatives showed more endorsement of Binding foundations (Loyalty, Authority, and Purity foundations) with an ingroup target. This general pattern was found when the framed, target-group was abstract (i.e., 'ingroups' and 'outgroups' in Study 1) and when target groups were specified about a general British-ingroup and an immigrant-outgroup (Studies 2 and 3). In Studies 2 and 3, both Individualizing-Ingroup Preference and Binding-Ingroup Preference scores predicted more Attitude Bias and more Negative Attitude Bias toward immigrants (Studies 2 and 3), more Implicit Bias (Study 3), and more Perceived Threat from immigrants (Studies 2 and 3). We also demonstrated that increasing liberalism was associated with less Attitude Bias and less Negative Bias toward immigrants (Studies 2 and 3), less Implicit Bias (Study 3), and less Perceived Threat from immigrants (Studies 2 and 3). Outgroup-individualizing foundations and Ingroup-Binding foundations showed different patterns of mediation of these effects.

Project description:The present study examined the effects of exercise utilising traditional resistance training (leg press) or 'cardio' exercise (recumbent cycle ergometry) modalities upon acute physiological responses. Nine healthy males underwent a within session randomised crossover design where they completed both the leg press and recumbent cycle ergometer conditions. Conditions were approximately matched for effort and duration (leg press: 4 × 12RM using a 2 s concentric and 3 s eccentric repetition duration controlled with a metronome, thus each set lasted 60 s; recumbent cycle ergometer: 4 × 60 s bouts using a resistance level permitting 80-100 rpm but culminating with being unable to sustain the minimum cadence for the final 5-10 s). Measurements included VO2, respiratory exchange ratio (RER), blood lactate, energy expenditure, muscle swelling, and electromyography. Perceived effort was similar between conditions and thus both were well matched with respect to effort. There were no significant effects by 'condition' in any of the physiological responses examined (all p > 0.05). The present study shows that, when both effort and duration are matched, resistance training (leg press) and 'cardio' exercise (recumbent cycle ergometry) may produce largely similar responses in VO2, RER, blood lactate, energy expenditure, muscle swelling, and electromyography. It therefore seems reasonable to suggest that both may offer a similar stimulus to produce chronic physiological adaptations in outcomes such as cardiorespiratory fitness, strength, and hypertrophy. Future work should look to both replicate the study conducted here with respect to the same, and additional physiological measures, and rigorously test the comparative efficacy of effort and duration matched exercise of differing modalities with respect to chronic improvements in physiological fitness.

Comparison of physiological responses of running on a nonmotorized and conventional motor-propelled treadmill at similar intensities.

Project description:This study aimed to test the agreement of the incremental test's physiological responses between tethered running on a nonmotorized treadmill (NMT) to matched relative intensities while running on a conventional motorized treadmill (MT). Using a within-subject crossover design, nine male recreational runners (age = 22 ± 5 years; height = 175 ± 6 cm; weight = 68.0 ± 16.6 kg) underwent two test sessions: one was an incremental intensity protocol on an MT; the other was on an instrumented NMT. Intensity thresholds at [Formula: see text]O2max, respiratory compensation point (iRCP), and lactate threshold (iLT) were registered for analysis, together with [Formula: see text]̇O2, [Formula: see text]̇E, ƒR, and blood lactate concentration ([Lac]). Comparisons were based on hypothesis testing (Student's T-test), effect sizes (Cohen's d), ICC, and Bland Altman analysis. Statistical significance was accepted at p < 0.05. Attained [Formula: see text]O2max (MT = 52.2 ± 7.3 mL·kg-1·min-1 vs NMT = 50.1 ± 8.1 mL·kg-1·min-1) and [Formula: see text]̇O2 at iRCP (MT = 46.3 ± 7.2 mL·kg-1·min-1 vs NMT = 42.8 ± 9.3 mL·kg-1·min-1) were not different between ergometers (p = 0.15 and 0.13, respectively), with significant ICCs (0.84 and 0.70, respectively) and Pearson's correlations (r = 0.87 and 0.76, respectively). The [Lac] at iLT presented poor agreement between conditions. Significant correlations were found (r between 0.72 and 0.83) for relative power values of i[Formula: see text]O2max (6.56 ± 1.28 W·kg-1), iRCP (4.38 ± 1.50 W·kg-1), and iLT (4.15 ± 1.29 W·kg-1) related to their counterpart obtained on MT. Results show that running on an NMT offers a higher glycolytic demand under the same relative internal load as running on an MT but with a similar aerobic response and correlated intensity determination.

Diverging responses to threats across generations in zooplankton.

Project description:Our understanding on how organisms evolutionarily cope with simultaneously occurring, multiple threats over generations is still elusive. In a long-term experimental study, we therefore exposed clones of a freshwater cladoceran, Daphnia magna, to threats from predation and ultraviolet radiation (UVR) during three consecutive parthenogenetic generations. We show that Daphnia can adapt to different sets of threats within three generations through modifying morphology, swimming behavior, or life-history traits. When faced with predator cues, D. magna responded with reduced body size, whereas exposure to UVR induced behavioral tolerance when again exposed to this threat. Such UVR-tolerant behavior was initially associated with a reduced clutch size, but Daphnia restored the reproductive output gradually through generations. The findings advance our understanding on how those common invertebrates, with a global distribution, are able to persist and rapidly become successful in a changing environment.
