Analyzing political conservatism as motivated social cognition integrates theories of personality (authoritarianism, dogmatism-intolerance of ambiguity), epistemic and existential needs (for closure, regulatory focus, terror management), and ideological rationalization (social dominance, system justification). A meta-analysis (88 samples, 12 countries,(More)
A meta-analysis by J. (2003) concluded that political conservatism is partially motivated by the management of uncertainty and threat. In this reply to J. Greenberg and E. Jonas (2003), conceptual issues are clarified, numerous political anomalies are explained, and alleged counterexamples are incorporated with a dynamic model that takes into account(More)
The equity heuristic is a decision rule specifying that parents should attempt to subdivide resources more or less equally among their children. This investment rule coincides with the prescription from optimality models in economics and biology in cases in which expected future return for each offspring is equal. In this article, the authors present a(More)
First collected by Charles Darwin in the Galapagos Archipelago, the Geospizinae, or " Darwin's finches, " have rightly been celebrated as a classic instance of the workings of evolution through natural selection. Among birds, Darwin's finches are rivaled only by the Hawaiian honey-creepers (Drepanididae) as a microcosmic exemplification of the principle of(More)
Sulloway (1996) proposed that personality traits developed in childhood mediate the association of birth order with scientific radicalism. Birth-order effects on traits within the five-factor model of personality were examined in three studies. Self-reports on brief measures of Neuroticism, Extraversion, and Openness in a national sample (N ϭ 9664) were(More)
The confluence model explains birth-order differences in intellectual performance by quantifying the changing dynamics within the family. Wichman, Rodgers, and MacCallum (2006) claimed that these differences are a between-family phenomenon--and hence are not directly related to birth order itself. The study design and analyses presented by Wichman et al.(More)
How do parents recognize their offspring when the cost of making a recognition error is high? Avian brood parasite-host systems have been used to address this question because of the high cost of parasitism to host fitness. We discovered that superb fairy-wren (Malurus cyaneus) females call to their eggs, and upon hatching, nestlings produce begging calls(More)
Species hybridization can lead to fitness costs, species collapse, and novel evolutionary trajectories in changing environments. Hybridization is predicted to be more common when environmental conditions change rapidly. Here, we test patterns of hybridization in three sympatric tree finch species (small tree finch Camarhynchus parvulus, medium tree finch(More)

cal structures and functions (9– 11). Instead, he besmirches the entire enterprise of political psychology, perpetuating canards from the right-wing blogosphere and lazy, empirically unsubstantiated accusations of " liberal bias. " For example, Shermer writes: Why are people conservative? Why do people vote Republican? The questions are typically posed(More)
