Jumping the gun will only result in less effective, less accurate, or even just plain bad decisions.
Think about what you need to know before you form an opinion about anything.
For example, someone may be described as intelligent and strong. Don’t jump the gun and judge them based on these first two adjectives, for the next two words describing them could be “corrupt” and “cruel.”
Justify any conclusion you come to with sufficient information.
Be sure to understand why you made the decision you did.
