Using more information in decision making is good because you can make an excellent decision if you know exactly what will happen if you did something, or what is the benefits of doing those things, and you can knows that if you asking some one who already experience that situation so, its better to make a few conversation to someone expert to know a little to make a decision and dont be arrogant in doing something in your own knowledge only but yes you need to trust your own research but its better to consult others to verify all those information.
