These white lies, however, are harmless as the motives behind them are not necessarily bad, researchers said.
The study looked at how often people expressed affection toward their partners even when they were not genuinely feeling it-otherwise known as deceptive affection.
This could be anything from complimenting your guy's haircut when you actually think it is heinous to kissing him goodbye even when you're really pissed, 'Fox News' reported.
As many as 57 participants (one person per couple) between the ages of 18-27 kept a week-long diary for the study.

The study showed that participants were faking their feelings an average of three times per week, according to Horan and study co-author Melanie Booth-Butterfield of West Virginia University.
"Although it's very common, the motives behind it aren't bad. The most dominant motives were to avoid conflict, negative feelings, and hurting your partner," said Horan.
"We don't always want to know the truth all the time," said Horan.
Researchers also said if your motives include covering up something major-like that you are over the relationship or that you have been cheating, you are probably doing more harm than good.
