Luck, Risk and the Impact of Chaos

"We always did that", a healthy habit?




The butterfly effect is a concept of chaos theory. The idea is that given initial conditions of a particular chaotic dynamic system that is sensitive to the initial conditions, any small discrepancy between two situations with a small variation in the initial data leads to a situation where both systems evolve in certain aspects of form completely different. Any very small and imperceptible event in one part of a system can cause a great change or a magnified effect elsewhere.

The video shows how an oversight leads to disaster when three trucks loaded with sugar cane fall into the river. In the balance of loads, a few grams could be balanced with the combined actions of the river and the wind, but when this does not happen and the imbalance gradually grows, the end is inevitable. The three trucks fall into the river and the theory of chaos is fulfilled.

In every space where people live or are permanently present, adverse, destructive events can always occur, which may be natural or induced by carelessness or bad intention. These events include earthquakes, fires, riots, explosions, and even totally human actions such as kidnappings, irruption of terrorists or demented shooting and killing (common in the United States). In order to face these situations, it is understood that there are security plans and protocols, responsible for the execution of these plans, equipment, continuous training, awareness talks, and much more.

In financial theory, it is known that greater risk of an investment in financial assets (bonds, stocks and others) must be accepted. There is a limit situation: absence of risk but low profitability when buying Treasury bonds; In this case you should only wait a while to gain access.


In real life, there is no such favorable neutral point, the only way to avoid risk simply is to avoid all action. Nothing is done, there is no risk, and where is the business, the company? In the case of trucks, they are not moved from one bank to another but there is no income. To win you have to accept the risk. This does not mean that it can ignore the risk, neglect safety measures, give extreme importance to the practice of "we have always done so", the same as did the trusted operators of the barge or truck that moved the trucks.

A routine activity for a risky process is cost-effective because activities that require time and money are avoided, which increase costs. Thus, no security measures are employed, no training is provided to those responsible, no equipment is spent on safety and emergencies, no talks are given to staff, there are no alternative plans or plans B because they make them demand time. Less cost, greater profitability; But when an adverse event can occur, that profitability disappears. The profitability of a routine action is lower than is assumed when the risk activity is assumed and the risk is incorporated into the profitability calculation.

Utility is "normal" when acting under the principle "we have always done so"), when there is non-concern about risk. When you accept it, you have:

Expected Utility = Normal Utility * Probability 1 + Losses * Probability 2

Some numbers: Normal utility = 100, probability 1 = 99%, probability 2 = 1-99% = 1%; Loss = 5,000

Then, expected profit = 100 * 99% + (-5,000 ** 1%) = 49. The profit without assuming the risk is 100, now it's only 40. It seems silly to win less, but winning 49 is much better than losing 5000.



The utility is smaller but it controls or reduces the possibility of occurrence of the disaster, which is very expensive. The loss of three trucks by carelessness, by doing "always things like before", is not any fun situation.

In your organization, do you do what is necessary not to "lose all three trucks"?
