Science has proven a number of things and knowing the reasoning behind some of them can help you make sense out of things. From attraction to what our brains love and more, here are 5 interesting facts that science has proven.

1. Girls are more attractive in groups

Does this explain girl groups?

Known as the The Cheerleader Effect, or also the Bridesmaid Paradox, it was brought to attention by How I Met Your Mother's Barney Stinson. Psychological Science confirmed the phenomenon to be true. We tend to average out facial features of males or females in groups, and rate individuals higher when seen within a group than alone.

2. The less you know, the more you think you know

Let's be real. Walter knows everything.

Also known as the Dunning-Kruger effect, the more incompetent you are, the more confident you are in your own competence. It means that people with this effect have a bsic inability to evaluate and recognize ineptitude, their own specifically. They don't know that they don't know anything and they believe they are better than everyone else.

3. Praise is good

Best employee in the world.

Want to be a better boss? Praise your employees. Studies have shown that when it comes to employee management, positive reinforcement is a good thing. And it even yields much better results and productivity than negative reinforcement.

4. Women like men with the "T"

Researchers discovered that men wearing a plain white t-shirt with a large black letter "T" on the front were significantly more attractive to the opposite sex. The shape of the T, turns out, subtly improves the wearer's "waist to chest" ratio, which is viewed as more masculine and desirable to women.

5. Women want what they can't have

Is that why we keep fawning over?

In the past, men were theorized to be more commonly associated with pursuing other people's partners. Or also know as, "mate poaching". However, there's also evidence to support that single women are far more likely to be attracted to a man if she knows he's already taken.
