Introduction

Research on the detection of lies and deceit has a prominent place in the field of psychology and law with a substantial research literature published in this field of inquiry during the last five to six decades (Vrij, 2000, 2008; Vrij et al., 2019). There are good reasons for this interest in lie detection. We are all everyday liars, some of us more prolific than others, we lie in personal and professional relationships (Serota et al., 2010; Halevy et al., 2014; Serota and Levine, 2015; Verigin et al., 2019), and lying in public by politicians and other public figures has a long and continuing history (Peters, 2015). However, despite the personal problems that serious everyday lies may cause and the human tragedies political lies may cause, it is lying in court that appears to have been the principal initial motivation for the scientific interest in lie detection.

Lying in court is a threat to fair trials and the rule of law. Lying witnesses may lead to the exoneration of guilty persons or to the conviction of innocent ones. In the US it is well-documented that innocent people have been convicted because witnesses were lying in court (Garrett, 2010, 2011; www.innocenceproject.com). In evaluating the reliability and the truthfulness of a testimony, the court considers other evidence presented to the court, the known facts about the case and the testimonies by other witnesses. Inconsistency with the physical evidence or the testimonies of other witnesses might indicate that the witness is untruthful, or it may simply reflect the fact that the witness has observed, interpreted, and later remembered the critical events incorrectly—normal human errors all too well known in the eyewitness literature (Loftus, 2005; Wells and Loftus, 2013; Howe and Knott, 2015).

(as it ends)

Is the rational course simply to drop this line of research? We believe it is. The creative studies carried out during the last few decades have been important in showing that psychological folklore, the ideas we share about behavioral signals of lies and deceit are not correct. This debunking function of science is extremely important. But we have now sufficient evidence that there are no specific non-verbal behavioral signals that accompany lying or deceitful behavior. We can safely recommend that courts disregard such behavioral signals when appraising the credibility of victims, witnesses, and suspected offenders. For psychology and law researchers it may be time to move on.

You Snooze, You Lose: Insurers Make The Old Adage Literally True

Here is an excerpt:

In fact, faced with the popularity of CPAPs, which can cost $400 to $800, and their need for replacement filters, face masks and hoses, health insurers have deployed a host of tactics that can make the therapy more expensive or even price it out of reach.

Patients have been required to rent CPAPs at rates that total much more than the retail price of the devices, or they’ve discovered that the supplies would be substantially cheaper if they didn’t have insurance at all.

Experts who study health care costs say insurers’ CPAP strategies are part of the industry’s playbook of shifting the costs of widely used therapies, devices and tests to unsuspecting patients.

“The doctors and providers are not in control of medicine anymore,” said Harry Lawrence, owner of Advanced Oxy-Med Services, a New York company that provides CPAP supplies. “It’s strictly the insurance companies. They call the shots.”

Insurers say their concerns are legitimate. The masks and hoses can be cumbersome and noisy, and studies show that about third of patients don’t use their CPAPs as directed.

But the companies’ practices have spawned lawsuits and concerns by some doctors who say that policies that restrict access to the machines could have serious, or even deadly, consequences for patients with severe conditions. And privacy experts worry that data collected by insurers could be used to discriminate against patients or raise their costs.

Creativity in unethical behavior attenuates condemnation and breeds social contagion when transgressions seem to create little harm

Abstract

Across six studies, people judged creative forms of unethical behavior to be less unethical than less creative forms of unethical behavior, particularly when the unethical behaviors imposed relatively little direct harm on victims. As a result of perceiving behaviors to be less unethical, people punished highly creative forms of unethical behavior less severely than they punished less-creative forms of unethical behavior. They were also more likely to emulate the behavior themselves. The findings contribute to theory by showing that perceptions of competence can positively color morality judgments, even when the competence displayed stems from committing an unethical act. The findings are the first to show that people are judged as morally better for performing bad deeds well as compared to performing bad deeds poorly. Moreover, the results illuminate how the characteristics of an unethical behavior can interact to influence the emulation and diffusion of that behavior.
