A wicked problem is:
a problem that is difficult or impossible to solve because of incomplete, contradictory, and changing [variables] that are often difficult to recognize.
According to Jeff Conklin (via Wikipedia), the defining characteristics of a wicked problem include:
- The solution depends on how the problem is framed and vice-versa (i.e. the problem definition depends on the solution).
- Stakeholders have radically different world views and different frames for understanding the problem.
- The constraints that the problem is subject to and the resources needed to solve it change over time.
- The problem is never solved definitively.
I don’t know about you, but sounds like obesity to me!
Weight Maven is written by Beth Mazur. Beth believes that obesity is more symptom than cause and that the real problem is our Western diet -- especially sugar, refined grains, and industrial oils. Beth writes about nutrition, ancestral health & food policy. And cats! 
I heartily concur with the definition and almost long for the days when my problems could be framed as obesity. That particular one solved, the solution has proven to be one long horror show in weirdness. So, now, instead of eating compulsively or battling urges, I am forced by a tyrant muse to write endlessly depressing and unmarketable rants and non-prose descriptions of angst trading off with blubbering expressions of gratitude for still being on this strange planet. Wicked problem indeed. :)
Well, can’t help you with that one! I added you to my feed, so guess that makes me an enabler ;).
