Naivety is often a trait of people who're lacking in life experience. If you don't experience the world first-hand, then it's inevitable that you'll be a little bit gullible or innocent. People normally become less innocent with age, but you can give yourself a helping hand by just saying yes to life.
What causes a person to be naive?
Someone might call you “naive” if you are overly trusting or lack experience in the world. Naive people are often so trusting of others around them that their natural innocence results in them getting cheated or hurt.
What does it mean to be a naive person?
