Most people make their decisions based on emotional input and then use their logical mind to rationalize the emotionally gratifying decision. This is easy and basically the way our minds are set up to function. Except, this process is flawed, unscientific and easily manipulated. To refrain from using emotion and use the higher order logical thought process, without considering what feels good, requires discipline. This is the skeptic's way of thinking and is a much more precise way of arriving at the truth. The best way to ensure personal emotion is not contaminating the analysis is to subject it to peer review and debate. Still, there will be disagreement but that's natural and healthy.
I only heard part of the interview with Lakoff and I agreed with what he was saying about framing. Democrats need to wise up and apply his principles of framing their message based on emotional appeal. People are terrible skeptics, I'm pretty cynical about that.
