Considerable evidence shows that repeated trials and more elaborate analytic training help little to 
mitigate problematic subject performance in dynamic decision making.  The paper uses a cognitive 
processing theory to account for poor learning.  Consistent with recent reviews of intuition in decision 
making, the theory suggests that there are two classes of cognitive processing called high and low roads 
to learning respectively.  The theory calls for massive decision training instead of analytic training for 
short and medium length training programs.  An experiment with 25 professionals randomly assigned to 
high and low road training programs cannot disconfirm the theory.
