Although other research has focused on how to detect a lie or how often people lie, This study wanted to look at whether she could convince people to lie less, then look at the effects of less lying.
Our Lying Selves
On average, Americans lie about 11 times a week, citing surveys by others. Some of those are whoppers. Other are white lies, often meant to spare feelings or save face.
Anita E. Kelly, PhD, professor of psychology at the University of Notre Dame, and her co-researcher, Lijuan Wang, PhD, assistant professor of psychology at the University of Notre Dame, assigned 110 people, aged 18 to 71, to one of two groups.
Both groups came to the lab each week to take a polygraph test.
One group was encouraged to stop telling major and minor lies for the 10-week study. The researchers suggested strategies for lying less, such as declining to answer questions.
The comparison group got no special instructions about lying. They were simply told that they would have to tell the researchers how many lies they had told that week when they were given the lie detector test.
Each group answered questions about their close relationships and about their mental and physical health each week.
For instance, they reported if they had trouble falling asleep or had headaches.
