People have different comfort zones when it comes to posting on Facebook. But by observing how much or how little they post — and what they post about — you can learn a lot about their personality types.

A new study published in Personality and Individual Differences explains this. Researchers collected data from 555 Facebook users and found the following four Facebook practices say different things about people's personalities.

The Good:

#1. They post a lot.

You are addicted to social media. It doesn't matter whether you are posting something important, or just pictures of the meal you cooked that day. What does this mean? There's nothing wrong with you — you're an extrovert.

#2. They post or share posts on intellectual topics.

Instead of updating on your personal life, you like to post about TEDTalks or new articles that interest you. Others might not be into it, but this trait is a sign that you're open-minded.

The Bad:

#1. They posts their achievements.

So, you got a new promotion or you just got engaged. What's your first thought? To tell the world about how happy you are, of course.

If your feed is mostly filled with your accomplishments, it's a sign you could be a narcissist who wants to make the world know how much better you are. Not good.

#2. They post a lot about their romantic life.

Some people get really dramatic about their romantic life, and think it's for public consumption to copy television and movies. But according to the study, this is a huge red flag. People who constantly post about their romantic life tend to be insecure. Researchers believe people who post about their partner are constantly compensating when they feel threatened of losing them.

Yikes! It might be time to re-evaluate some things we're posting and work on ourselves instead.
