#1 People Believe They Have More Restraint Than They Actually Possess. New research from the Kellogg School of Management examines why individuals regularly succumb to greed, lust and self-destructive behaviors — and demonstrates that individuals believe they have more restraint than they actually possess, which ultimately leads to poor decision-making:

People are not good at anticipating the power of their urges, and those who are the most confident about their self-control are the most likely to give into temptation.

So, if you’ve got a guy or gal with fidelity or other issues, you both will need some support — especially if they boast they can control themselves.

#2 The Liar in Your Life. Robert Feldman, psychology professor at the University of Massachusetts Amherst and expert on lying, says what we think about how and why people lie is wrong — his insights into the world of lying are in his new book, The Liar in Your Life: The Way To Truthful Relationships.

In the book, he debunks the myths and says we’re not only bad at detecting falsehoods, but in fact are strongly and unconsciously willing to believe other people’s lies to make our lives easier — that people aren’t inclined to question the daily interactions they have with family members, or even strangers.

His research also finds that strangers meeting face-to-face for the first time will tell lies three times within 10 minutes, and if strangers meet through a computer conversation, he says, they’re even more likely to lie.  ABC’s got an excerpt, if you want to try before you buy.
