Narcissism causes quite a few problems in our society.
Being related to a narcissist is rough, being friends with one is a headache and dating one is an absolute nightmare.
Sometimes, though, narcissists aren't all that easy to identify. You can be three months into dating someone before realizing your boyfriend or girlfriend is a narcissist!
In case you're unfamiliar with narcissism, the Science Of Us video above explains how narcissists typically have three traits: an unrealistic sense of his or her own superiority, a sense of entitlement and a lack of empathy.
We won't give it away, but the video also provides us with a very handy question to ask potential narcissists in an effort to identify one quickly and easily.
Hint: Narcissists are very self-aware.
