New research, published in Organisational Behavior and Human Decision Processes, suggest feelings of disgust lead to increases in deceitful behavior that would benefit the self.

In their first experiment, researchers had participants rate consumer products that are known to elicit a disgust response – such as diapers and diarrhea medicine – or neutral consumer products – such as vitamins and pens. They were then tasked to flip a coin. If it landed on heads, the participants could earn $2. If it landed on tails, there was no promise of money. Some participants were told the reverse. The coin flip was committed alone and participants were later asked to report the result. This presented a dilemma of sorts: the participants could lie, get the US$2 and never be found out.

So what happened when participants were left alone to flip the coin? 63% of the disgusted and 52% of the control participants reported a favorable coin flip. Remembering that odds are 50% for a favorable outcome, researchers concluded it’s clear that the disgusted participants were engaging in higher levels of deception.

In a second experiment, participants were asked to describe either their most disgusting experience or a typical uneventful evening. Those who described their most disgusting experience were nearly twice as likely as the others to lie about solving anagrams in order to obtain more credit for completing a survey. How did the researchers know participants were lying? One of the anagrams was impossible to solve.

The researchers also ran two other experiments to test their theory with the same result: those who felt disgust were more likely to participate in deceitful behavior.

A new study recently published in the Journal of Experimental Psychology has confirmed that a new era of airport security screening is upon us.

The study conducted by Thomas Ormerod of the University of Sussex and Coral Dando of the University of Wolverhampton, was partially funded by the British government.

Two hundred four mock airplane passengers, including acting students and undercover cops, were given cover stories and asked to attempt to deceive security agents in real airport screenings in Europe. As an extra incentive, the mock passengers were given money if they successfully avoided detection by the security agents.

The new method of screening is based on establishing rapport and asking passengers open-ended conversational questions while they observe people’s body language and responses, including changes in behavior such as increasingly shorter responses, or evasive or erratic responses. Trained security agents who used this new screening method successfully detected 66% of the mock passengers. Agents who used different methods detected a measly 3%.

The findings of this study could have important implications for preventing terrorist attacks or catching criminals, the researchers said. Moreover, the findings highlight the importance of training to read many of the nonverbal behaviors offered in the Humintell suite of online training courses.
