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.
Somehow you need to get from prejudice and mistrust to 1) the curiosity to find out what people are capable of, and 2) accepting responsibility for the scalability and sustainability of the decision-making process. These are challenges of organisational and personal development, closely related also to strategy deployment.
And if possible for each example, specify what made you mistrust them, and what would have made you trust them.
On the opposite side of the spectrum, do you have two examples of situations in which it was easy for you to trust someone's words? What made you trust them?
