On gut feeling as decision making tool

Many a time we find ourselves agonizing over some decision. We sometimes look back and, especially when unhappy about it, say that it somehow did not feel right when deciding a certain way, despite what seemed like supporting evidence. All in all, mastering one's own gut feeling is as elusive a task as any. Only few admit to relying on gut feeling, since our society recognizes analytical skills more than something hardly quantifiable and defensible only in retrospect. In an interview with Context Magazine, Deepak Chopra lets the reader in to the high-level decision making process of a Sony executive. The following excerpt may provide some with a useful tool:
The truth is that the body responds contextually to everything that happens in the mind. The mind doesn'’t have a specific location in the body. It isn't just in the brain.

If you say, "I have a gut feeling about such and such," you aren'’t speaking metaphorically. The phrase is rooted in science. The cells in your gut make the same peptides that your brain makes when it has ideas. You probably can trust your gut cells even more, because they havenÂ’t yet evolved to the stage where they doubt their own thinking.

I once interviewed Masaru Ibuka, founder and chairman of Japan'’s Sony Corp., who was supposed to have great business instincts. I asked him, "“What is the secret of your success?"” He said he had a ritual. Preceding a business decision, he would drink herbal tea. Before he drank, he asked himself, "“Should I make this deal or not?"” If the tea gave him indigestion, he wouldn'’t make the deal. "“I trust my gut, and I know how it works,Â" he said. "“My mind is not that smart, but my body is."”
So, when preparing to make a decision, if you have to reach for that Nexium, think of Chopra/Ibuka.
