Bayesian principles show up across many domains of human cognition, but wishful thinking-where beliefs are updated in the direction of desired outcomes rather than what the evidence implies-seems to threaten the universality of Bayesian approaches to the mind. In this Article, we show that Bayesian optimality and wishful thinking are, despite first appearances, compatible. The setting of opposing goals can cause two groups of people with identical prior beliefs to reach opposite conclusions about the same evidence through fully Bayesian calculations.

We extend their analysis to argue that structural factors bias and perpetuate behavioral science toward the i-frame. Addressing this problem fully will require structural changes to the training, peer review, and granting structures that confront research scientists.

Philosophers have long investigated this question of personal identity with thought experiments. Cognitive scientists have joined this tradition by assessing lay intuitions about those cases. Much of this work has focused on judgments of identity continuity.

Recent research has often assumed that participants are indicating a change in numerical, rather than qualitative, identity. Investigations into this matter have been hampered by the fact that English has no clear way to demarcate one type of identity from the other. To resolve this matter, we develop and test a novel task in Lithuanian, which has lexical markers for numerical and qualitative identity.

Here, we examine whether, and in what ways, ordinary citizens conceptualize the corporation as a person. We present evidence that corporations are anthropomorphized, but only to a certain degree.

Yet a guiding assumption of many advocates is that the biasing effect of advocacy is controllable. Lawyers, for instance, are taught that they can retain unbiased beliefs while advocating for their clients and that they must do so to secure just outcomes.
View Article and Find Full Text PDFA long tradition of psychological research has explored the distinction between characteristics that are part of the self and those that lie outside of it. Recently, a surge of research has begun examining a further distinction. Even among characteristics that are internal to the self, people pick out a subset as belonging to the true self.

We examine conformity and consistency in sartorial choices surrounding a common life event of new norm exposure: relocation. A large-scale dataset of individual purchases of women's shoes (16,236 transactions) across five years and 2,007 women reveals a balance of conformity and consistency, moderated by changes in location socioeconomic status. Women conform to new local norms (i.

Their very optimistic assessment is limited by statistical misconceptions and by causal inferences from selectively interpreted, correlational data.

Faces impart exhaustive information about their bearers, and are widely used as stimuli in psychological research. Yet many extant facial stimulus sets have substantially less detail than faces encountered in real life. In this paper, we describe a new database of facial stimuli, the Multi-Racial Mega-Resolution database (MR2).

Yet there have been no systematic investigations of what types of cognitive damage lead people to appear to no longer be themselves. We measured perceived identity change in patients with three kinds of neurodegenerative disease: frontotemporal dementia, Alzheimer's disease, and amyotrophic lateral sclerosis.

Important choices such as hiring or dating someone are often based on the clothing people wear, and yet we understand almost nothing about the objective features that make an outfit fashionable.
View Article and Find Full Text PDFIt has often been suggested that the mind is central to personal identity. But do all parts of the mind contribute equally? Across five experiments, we demonstrate that moral traits-more than any other mental faculty-are considered the most essential part of identity, the self, and the soul. Memory, especially emotional and autobiographical memory, is also fairly important.
View Article and Find Full Text PDFPositive emotions are often treated as relatively similar in their cognitive-behavioral effects, and as having unambiguously beneficial consequences. For example, Valdesolo and DeSteno (2006) reported that a humorous video made people more prone to choose a utilitarian solution to a moral dilemma. They attributed this finding to increased positive affect.
View Article and Find Full Text PDFThe first seven chapters of Doing without Concepts offer a perfectly reasonable view of current research on concepts. The last chapter, on which the central thesis of the book rests, provides little actual evidence that using the term "concept" impedes scientific progress. It thus fails to demonstrate that this term should be eliminated from the scientific vernacular.

In contrast, selecting just 2 colored letters at 10 letters/s results in easy detection of the first target but poor recall for the second when it appears 200-500 ms later. This attentional blink disappears when all letters must be reported; instead, performance drops more gradually over serial position (Nieuwenstein & Potter, 2006).
