decision-making and beliefs

I wrote my dissertation on decision-making in 1968.  I write that sentence to emphasize that I have an interest in the topic.  I mean the topic of tools to make decisions with.  I just read an article on Cardano, born in the 1600's.  It mentioned that the man consulted astrologers.  As usual, the subject was the irrationality of fortune-telling, crystal balls and related subjects.

That article made me think of the coin in my pocket.  I have taken to carrying a 25 cent piece, a "quarter" (of a dollar) as an aid in decision-making.  I use it for a specific purpose and that purpose is to test my feelings in this way:

When I have trouble making up my mind, yea or nay, I like to assign, say, "yea" to heads and flip the coin.  I flip it in the air and let it land on a cushion or bed without touching it. I look to see whether it lands heads or tails.  Let say I see the "tails" side has landed up.  So the coin indicates "Nay" or not Harry's for dinner or whatever.  THEN, I ask myself if I like that result.  If I feel disappointed, I ignore the coin & go to Harry's.  If I don't feel bad , I elsewhere.  

When you see me come out of the fortune teller's place, be careful what you conclude. 

The situation reminds me of searching a question on the internet.  I have found that other searches by people often extend or re-direct my thinking. As I found with Storyworth questions about my life and memories, I found that their questions led me to subjects and opinions that I would not have found using only my thoughts.
