Finding the most influential people is an NP-hard problem that has attracted many researchers in the field of social networks. The problem is also known as influence maximization and aims to find a number of people that are able to maximize the spread of influence through a target social network. In this paper, a new algorithm based on the linear threshold model of influence maximization is pro...

People were given highly constrained low budgets of mate dollars to allocate across various characteristics pertaining to their ideal partners and to their ideal selves for longand short-term mating. First, results replicated findings from Li et al. (2002) and Li & Kenrick (2006). For ideal long-term mates, men prioritized physical attractiveness and women prioritized social status. For ideal s...

The U.S. military, despite spending over $13 billion, appears powerless to stop the Iraqi insurgency’s improvised explosive devices (IEDs), which cause most of the military’s casualties and prevent victory by showing lawlessness and insecurity. However, this view ignores substitution effects we consider here. Using rational choice and expectations models, we find a backward-bending supply curve...

Two studies tested the prediction that narcissism would moderate the link between frustration and prejudice against immigrants in that individuals high in narcissism would show a stronger association than others. In Study 1 (n = 156), participants completed online s...

We demonstrate that the agrarian unrest in the United States between 1870 and 1900 can be given an economic explanation, despite its association with increases in the real price of agricultural produce. It was not merely the result of nominal illusions as other scholars have suggested. Falling transportation costs allowed for the extension of the frontier and for more farmers to enter the inter...

The saccadic eye movements that people make when thinking have been largely ignored in the eye-movement literature. Nevertheless, there is evidence that such eye movements are systematically related to internal thought processes. On average, people move their eyes about twice as often when searching through long-term memory as they do when engaged in tasks that do not require such search. This ...

People everywhere select among multiple alternatives, but are they always making choices? In five studies, we found that people in U.S. American contexts, where the disjoint model of agency is prevalent, are more likely than those in Indian contexts to construe their own and other individuals’ behaviors as choices, to construe ongoing behaviors and behaviors recalled from memory as choices, to ...

Several researchers have studied technology trust in terms of the technological artifact of the technology. Two different types of trusting beliefs could apply to websites. First, the trusting beliefs may relate to interpersonal characteristics such as benevolence, competence, and integrity. Second, they may relate to technology characteristics such as helpfulness, functionality, and reliabilit...
