Find an ex of a recent major decision (whether in business, politics, etc.) that was made based on assumptions that turned out to be incorrect.
describe why at least 2 assumptions for this decision were incorrect, and describe what led to their use as a basis for the decision.
What would you have done to test the validity of the assumptions? What specific kinds of research, testing, or surveying might you have performed if you were the decision maker in a similar situation in the future? What, if anything, would you do differently about the assumptions being made?
