Interesting short article on the halo effect in decision-making:
Rather than search for simplistic formulas that promise success, managers would do better to adjust their thinking. First, they must recognize the fundamental uncertainty of the business world. Decisions become a matter of probabilities, ways to improve the odds of success, while never imagining that high performance can be engineered. Thinking this way does not come naturally. People want the world to make sense, to be predictable, and to act according to clear rules of cause and effect. Managers want to believe their business world is similarly predictable, that specific actions will lead to certain outcomes. Yet strategic choice is inevitably an exercise in decision making under uncertainty.
