What are some psychological facts that people don't know?

After reading the answers with almost similar content, here's my observation with different perspective.

So, lets get started.

• Don't express your love.

Out for shopping, you loved a dress and you are all excited; “ I love this dress, it's so pretty”.

Now, the shopkeeper too know that and will put any price, because he/ she knows you'll pay that price.

P.s- always bargain, or else, observe your mom.

• First impression a.k.a body language.

Always have an alpha body language.

Not to mention, hands out of your pocket.

• Want people to listen you, be quiet.

The less you talk, the more weighted your words will be for others.

Don't trust me, go try it out.

• Wanna sound smart, throw figures.

“76% people deviate from their resolution by the end of 2 months”.

“People deviate from their resolution by the end of 2 months”.

You be the judge here.

• Wanna be a good leader, call name.

If you want to assign a work, call people by their name. There's a probability that by 76% time, you'll get your work on time and respect for sure.

Reason, when you call them by their name, you associate them with a familiarity i.e their name. People are more comfortable with familiarity.

I'll add more if you want, till then, have a nice day.
