A widespread presumption in the law is that giving jurors nullification instructions would result in "chaos"-jurors guided not by law but by their emotions and personal biases. We propose a model of juror nullification that posits an interaction between the nature of the trial (viz. whether the fairness of the law is at issue), nullification instructions, and emotional biases on juror decision-making. Mock jurors considered a trial online which varied the presence a nullification instructions, whether the trial raised issues of the law's fairness (murder for profit vs. euthanasia), and emotionally biasing information (that affected jurors' liking for the victim). Only when jurors were in receipt of nullification instructions in a nullification-relevant trial were they sensitive to emotionally biasing information. Emotional biases did not affect evidence processing but did affect emotional reactions and verdicts, providing the strongest support to date for the chaos theory.

In cases of euthanasia, determinations of guilt may be influenced by legal and extra-legal factors. This study explores the role that nullification instructions play in juror decision making. A defendant may be viewed as less culpable if the act was done out of mercy and jury nullification may occur as a result.

Smiles are the most commonly and frequently used facial expressions by human beings. Some scholars claimed that the low accuracy in recognizing genuine smiles is explained by the perceptual-attentional hypothesis, meaning that observers either did not pay attention to responsible cues or were unable to recognize these cues (usually the Duchenne marker or AU6 displaying as contraction of muscles in eye regions). We investigated whether training (instructing participants to pay attention either to the Duchenne mark or to mouth movement) might help improve the recognition of genuine smiles, including accuracy and confidence.

In a mock-trial study, jurors read evidence about a doctor who had killed a terminally ill patient at the patient's request. We tested whether instructing jurors about jury nullification (ie jurors' power to return a not-guilty verdict even when legal guilt is beyond doubt, often because the law would result in unjust convictions) would exacerbate the effect of pre-trial euthanasia attitudes on their verdicts - compared to standard, pattern jury instructions. We also hypothesized that anti-euthanasia pre-trial attitudes would result in moral outrage at the defendant and higher conviction rates, but pro-euthanasia attitudes would prompt feelings of moral outrage at the law and lower conviction rates.

This experiment examined whether nullifying a stereotypic threat about sex-related abilities in mental rotation in women athletes increased facility with rotations. Women athletes and nonathletes (N = 64) were told that they would be performing mental rotation presumed to create an implicit stereotypic threat. Then 32 participants learned that the mental rotation tasks required the same abilities as those mastered by athletes, presumed to nullify the stereotypic threat.
