Back your decision with sufficient information.
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.” Jumping the gun will only result in less effective, inaccurate, or even just bad decisions.
Justify any conclusion you come to with sufficient information.
Be sure to understand why you formed the opinion or decision you made.
