Or we think of the blowback effect. The CIA covertly funds a government or sect, only to have the power that rises out of it be 'evil' back to us.
Stephen Dubner and Steven Levitt wrote a best selling book on unintended consequences. Freakonomics is chapter after chapter of the 'rogue effects' of rational utility-maximization.
Unintended Consequences. There can be 'good' unintended consequences, but many pundits prefer the negative connotation. Well, I am here to bust the bubble of this negative thinking.
My good friend, Sophie, and I have been enjoying early (EARLY!) morning hikes through the Riparian Park near our house. Taking a dog hiking there (especially a breed of dog bred for birding) isn't always the fondest of idea by other riparian hikers. One look at this dog and my fellow non-dog friendly hikers immediately protest her existence. "She will charge the birds" is one complaint.
But my good friend Sophie and I hiked anyway. We took the trails around the drained ponds, trails away from the birders and 'big time' photographers. We wandered the 'back roads'. With camera straps around my neck and Sophie safely leashed to my waist, I immediately became caught up in the hunt for migrating birds. Sophie's task was to walk with me (silently), to stop with me (silently), to be silent with me (even more than silent), to sit in the marshes with me (totally silently). I became so aware of the birds and the vegetation that I forgot Sophie was by my side. Never once did I utter a 'sit' or 'stay' to her. I assumed she knew to do it - silently.
Today I found an unintended consequence to our birding hikes. On a normal walk, she now heels like a dog that has been long in training! She (silently) has learned to read my body language and my movements. She doesn't need the verbal reminder to heel or to stop/sit. She is a dog on auto pilot.
Oh, sometimes I just love unintended consequences.
