"you do not fight complexity with complexity"

"“Modern finance is complex, perhaps too complex. Regulation of modern finance is complex, almost certainly too complex. That configuration spells trouble. As you do not fight fire with fire, you do not fight complexity with complexity. Because complexity generates uncertainty, not risk, it requires a regulatory response grounded in simplicity, not complexity
...
Heuristic strategies are simple rules of thumb that solve complex uncertain situations precisely because of their simplicity, not despite it. More calculation, time, and information are not always better. Less can be more.
...
A good heuristic can be better than a complex strategy when used in the proper environment. Less can be more. The recognition heuristic is ecologically rational when a correlation exists between recognizing an option and the criteria for judgment.
...
One main point in the business world is that entrepreneurs can generate profit in the markets, à la Knight, precisely because they intelligently deal with immeasurable, irreducible uncertainty.
...
In most business situations knowledge is much less than perfect and uncertainty prevails over risk. Heuristic strategies that are successfully used in business decision-making exploit the structure of information in the environment, rely on simplicity to overcome the complexity of situation, and are indispensable when faced with irreducible uncertainty. One central observation is that less can be more. That is, less information, calculation or time, can be beneficial under particular circumstances to achieving a given task."
