Soelberg teached his students at MIT Sloan School of Management how to perform the rational choice strategy, in which the decision maker:
Identifies a set of options;
Identifies the way of evaluating these options;
Weights each evaluation dimension;
Does the rating;
Picks the option with the highest score.
Soelberg taught his students how to apply the rational choice strategy
And in his PhD thesis he studied the decision strategies his students used to select their jobs as they graduated.
But he was wrong; his students did not systematically compare options. Soelberg found that they were using their gut feelings, and he could predict with 87% accuracy their ultimate choice, three weeks before they did their decision .
