When I wrote a paper on agent modelling in consumer behaviour, which no   
   one read many years ago, we modelled uncertainty as a random percentage   
   assigned to any outcome.  Fuzzy logic stuff.   
      
   >From my post graduate life in business, ick, I find that uncertainty is   
   assigned to an outcome as a simple process of subtraction.  People feel   
   that they can make X for investment Y but they have uncertainty of T,   
   so they may make X+T to X-T, it is my experience that people manage   
   this in reality by taking the likely benefits to be X-T when they take   
   uncertainty as a factor, and only go higher when they ignore risk.
