Is my thought correct or wrong?
I'm a manager (3 Years exp in dealing with people) and I always think, to be able to take right decisions, you need to have a lot of real life experiences. Without that the decisions are simply based on gut feeling and intuitions which are likely to be wrong.
Due to this prejudice, I cannot trust anyone's words unless they prove their claims.
Am I going the wrong way? Are there any experienced managers who can help me with this dilemma?
As a “junior” person, I generally agree with this. But not prescriptively, more like a rule of thumb.
Age and life experience are not exactly connected. A younger person could have more life experience than an older one, depending on the intensity and selection of their past experiences.
So although I agree that life experience often helps you be a better manager, and junior people often have less, I don’t think that fact justifies a prejudice.
