ABSTRACT
Assessing probabilities for
relevant and sometimes unique events in real-world decision situations can be problematic.
This paper elucidates a 2-step process for assigning probabilities to relevant events
enabling a rational decision process to supersede decision choices based only on
a gut feeling. After assessing probabilities the decision maker can confirm or reverse
a gut feeling choice using expected values for each available act and traditional
decision theory methodology. A simple example involving a buy now or buy later situation
with market uncertainty illustrates the process for typical yes or no decisions.
