Study shows people are more lenient to political lies

A new study, suggests that people have more leniency for political lies when they bolster a shared belief that a specific political stance is morally right.

Researchers at the University of Illinois at Chicago (UIC) undertook the study and published online in Social Psychological and Personality Science.

Dr Allison Mueller, UIC doctoral candidate in Psychology and lead author of the study said: "It appears to be because those lies are perceived by supporters as an acceptable and perhaps necessary means to achieve a higher moral end.

"A troubling and timely implication of these findings is that political figures may be able to act in corrupt ways without damaging their images, at least in the eyes of their supporters."

Dr Mueller and Linda Skitka, UIC Professor of Psychology, examined responses to a 2014 survey where participants read a political monologue about federal funding for Planned Parenthood that they believed was previously aired over public radio.

Respondents were randomly assigned one of two feedback conditions where upon completion they were informed that the monologue they had just read was either true or false.

They were then asked to report the extent to which they believed that the speaker was justified in delivering the monologue. Then, they reported their attitude positions for federal funding of women's reproductive services and their moral conviction for the issue.

Although honesty was positively valued by all respondents, the researchers found that lying that served a shared moralised goal was more accepted and advocacy in support of the opposing view, or non-preferred end, was more condemned, regardless of whether the statement was true or false.

Prof Skitka says the findings expand knowledge of the moral mandate in two ways.

"Moral conviction for a cause, not the fairness of procedures, may shape people's perceptions of any target who engages in norm-violating behaviours that uphold moralised causes, such as federally funded family planning in this situation," she said.

"The findings also suggest that, although people are not comfortable excusing others for heinous crimes that serve a moralised end, they appear comparatively tolerant of norm violations like lying."
