Individual differences in cognitive abilities and skills can predict normatively superior and logically consistent judgments and decisions. The current experiment investigates the processes that mediate individual differences in risky choices. We assessed working memory span, numeracy, and cognitive impulsivity and conducted a protocol analysis to trace(More)
We introduce the Berlin Numeracy Test, a new psychometrically sound instrument that quickly assesses statistical numeracy and risk literacy. We present 21 studies (n=5336) showing robust psychometric discriminability across 15numerical questions about risk). The Berlin Numeracy Test was found to be the strongest predictor of comprehension of everyday risks(More)
Some research on attentional control in working memory has emphasized theoretical capacity differences. However, strategic behavior, which has been relatively unexplored, can also influence attentional control and its relationship to cognitive performance. In two experiments, we examined the relationship between attentional control (measured with operation(More)
Recently, there has been an increased interest in folk intuitions about freedom and moral responsibility from both philosophers and psychologists. We aim to extend our understanding of folk intuitions about freedom and moral responsibility using an individual differences approach. Building off previous research suggesting that there are systematic(More)
In several experiments, we demonstrate that controlled cognition (e.g., " System 2, " as measured by the cognitive reflection test) can give rise to seemingly intuitive judgments (e.g., " System 1 "). Experiment 2 examined a bias that occurs when price estimates are made in the presence of unfamiliar (disfluent) money. Paradoxically, more controlled(More)

In a series of five experiments, we demonstrate that moral judgments and folk intuitions are often predictably fragmented. Drawing on the domains of ethics and action theory, we illustrate ways in which judgment tends to be associated with stable individual differences such as personality traits and reflective cognitive styles. We argue that these(More)
Sexually Transmitted Diseases (STDs)-including HIV/AIDS-are among the most common infectious diseases in young adults. How can we effectively promote prevention and detection of STDs in this high risk population? In a two-phase longitudinal experiment we examined the effects of a brief risk awareness intervention (i.e., a sexual health information brochure)(More)
A side effect is a foreseen but not intended consequence of some intended action. Joshua Knobe has discovered that most people judge that a good side effect is not brought about intentionally, but a bad side effect is brought about intentionally. These responses are meant to indicate something about the folk concept of intentional action— namely, that(More)
Experimental philosophers have gathered impressive evidence for the surprising conclusion that philosophers' intuitions are out of step with those of the folk. As a result, many argue that philosophers' intuitions are unreliable. Focusing on the Knobe Effect, a leading finding of experimental philosophy, we defend traditional philosophy against this(More)
