People have tendency work on instincts. While making decisions this may lead to perception biases. This would not be good practice. The person would make decisions in a way that fits one’s concept, viewpoints, attitudes, emotion. This would be illusion and escape from reality.
See a person!!! You would have certain perception on the person with respect to their clothing, surrounding and people or things around him. If he/she were to be in a different situation you would have perceived the person differently. Once you get to know the person, talk to the person then socialize with the person your perception towards the person mostly differs from your first acquaintance and you are much for clear about person.
Likewise, the decision maker should be able to make rational decision based on fact rather than instincts as far as possible. In some cases it is difficult to identify the real problem/issue where we tend to use our instincts but we can minimize it through discussion, communication and interaction with colleagues and try to get into “what real problem is?” As there is saying “we don’t see reality and we interpret what we see and call it reality”
