False-Positive Psychology
TLDR
It is shown that despite empirical psychologists’ nominal endorsement of a low rate of false-positive findings, flexibility in data collection, analysis, and reporting dramatically increases actual false- positive rates, and a simple, low-cost, and straightforwardly effective disclosure-based solution is suggested.
P-Curve: A Key to the File Drawer
TLDR
By telling us whether the authors can rule out selective reporting as the sole explanation for a set of findings, p-curve offers a solution to the age-old inferential problems caused by file-drawers of failed studies and analyses.
Do Messages about Health Risks Threaten the Self? Increasing the Acceptance of Threatening Health Messages Via Self-Affirmation
Two studies demonstrate that self-image maintenance processes affect the acceptance of personally relevant health messages. Participants who completed a self-affirmation were less defensive and more…
Data from Paper “False-Positive Psychology: Undisclosed Flexibility in Data Collection and Analysis Allows Presenting Anything as Significant”
The data includes measures collected for the two experiments reported in “False-Positive Psychology” [1] where listening to a randomly assigned song made people feel younger (Study 1) or actually be…
Pay-what-you-want, identity, and self-signaling in markets
TLDR
It is shown that often, when granted the opportunity to name the price of a product, fewer consumers choose to buy it than when the price is fixed and low, driven largely by individuals’ identity and self-image concerns.

TLDR
Switching from corporate social responsibility to what the authors term shared social responsibility works in part because customized contributions allow customers to directly express social welfare concerns through the purchasing of material goods.
p-Curve and Effect Size
Journals tend to publish only statistically significant evidence, creating a scientific record that markedly overstates the size of effects. We provide a new tool that corrects for this bias without…
Paying to Be Nice: Consistency and Costly Prosocial Behavior
TLDR
It is suggested that costly prosocial behaviors serve as a signal of prosocial identity and that people subsequently behave in line with that self-perception, so subsequent behavior is less likely to be consistent and may even show the reductions in prosocial behavior associated with licensing.
Intuitive confidence: choosing between intuitive and nonintuitive alternatives.
TLDR
The authors found that decreasing intuitive confidence reduced or eliminated intuitive biases, indicating that intuitive biases are not inevitable but rather predictably determined by contextual variables that affect intuitive confidence.
The effect of accuracy motivation on anchoring and adjustment: do people adjust from provided anchors?
TLDR
It is shown that although accuracy motivation fails to increase the gap between anchors and final estimates when people are uncertain about the direction of adjustment, accuracy motivation does increase anchor-estimate gaps whenPeople are certain about thedirection of adjustment.
