How do you make decisions when Red Herrings are bombarded at you?

I have been in countless situations where many people are throwing incorrect information at me from all directions - literally every person in the situation I encounter leads me down the wrong garden path with false information. Should I take these as a process of elimination to find the right answer or should I ignore everyone and all these red herrings that get bombarded at me. If that is the case how do I find the answer?
