Study: Lying makes you happier

Not that this is a big surprise, but here goes:

On April 7 Kate tweeted this:

“@XXXX you're so energetic miss gardener:) tomorrow we plant our organic veges inside then will move outside when they sprout yay!” 

However today, when someone asked if she had a garden, she tweeted this:

"no but my kids seem to think we need one"

Oh no she didn't!

According to studies, small embellishments can have positive psychological effects. In a 2008 study, researchers found that college students who exaggerated their GPA in interviews later showed improvement in their grades. Their fiction, in other words, became self-fulfilling. "Exaggerators tend to be more confident and have higher goals for achievement," said Richard Gramzow, a psychologist at the University of Southampton in England and one of the study's coauthors. "Positive biases about the self can be beneficial." People who deceive themselves also tend to be happier than people who do not, some research suggests. There are social payoffs, too: Studies have shown that people who lie frequently are viewed as friendlier and more amiable than their more truthful counterparts.

Kate's web of lies has caught up with her time and time again, and yet something keeps driving her to keep on spinning them. Is it because it makes her happier to put up such a facade?
