Decision under uncertainty

To do so, it is first necessary to understand how decision makers interpret and use uncertainty information. Following a general overview of user types and needs for uncertainty information, Sections 2. The descriptive perspective identifies psychological factors that influence how users perceive risk and uncertainty and process uncertainty information. The prescriptive perspective, statistical decision theory, considers how the major factors inputs, preferences or goals, outputs, etc.

Decision under uncertainty

Accelerating technological change Aging population trends in developed economies An increasing sense of uncertainty reflects a changing environment that will impact the choices we make. Recognizing and accommodating these changes provides the opportunity to increase decision making effectiveness.

Decision making always involves uncertainty Even the simplest decisions carry some level of uncertainty. In choosing a cup of coffee, there will be at least the possibility that the coffee doesn't taste good, is not hot, or will not provide the usual pleasurable feeling.

Complete certainty would imply carrying out a fixed procedure or algorithm, not making a choice. So, how does decision making impact uncertainty? Decision making can be described as the process of reducing uncertainty about solution options by gaining sufficient knowledge of the options to allow a reasonable selection from among them.

Uncertainty is reduced, but never eliminated. If that were possible, we would be able to predict the future without error. Seldom are decisions made with absolute Decision under uncertainty because complete knowledge of the alternatives is not possible or practical. There is also a distinction in levels of uncertainty.

In "precise uncertainty" probabilities for solution outcomes can be known or gathered, such as in games of chance. Other risks, such as some of those suggested in the bullet list above, will often have probabilities that are not knowable.

Why does it seem like uncertainty is increasing? Events globally and locally, along with a high level of media attention, are revealing some of the risks and uncertainty that underlie decisions that impact our perception of security.

In reality, there is no permanent security in this world. Choosing not to take risks does not secure one from changes that can take place in the environment, economy, technology, society, or government.

Obvious emotions of fear and anxiety arise whenever we are separated from things that make us feel secure. People experience these emotions, particularly separation anxiety, when they move away from homes and loved ones at many stages during life. It should be expected, and acknowledged, that we will have fear of failure, loss, or rejection when we take on risk or uncertainty.

Losing a sense of control over your life can be unsettling. How should we change our decision making when uncertainty increases? Recognizing that uncertainty brings some level of separation anxiety can help reveal some ideas for managing decision making in uncertainty.

Here are some ideas to consider for times of high decision uncertainty. Reduce the time horizon for decisions. Build a bridge to the future by taking smaller steps, keeping something familiar and secure with each step.

Learn as much as possible about options before choosing. Knowledge makes the new seem more familiar, reducing separation anxiety. When the environment is providing lots of uncertainty, defer risks that are in your control. For example, when there is economic uncertainty, postpone taking on debt for buying a new car.

To successfully cope with these situations, the nervous system has to be able to estimate, represent, and eventually resolve uncertainty at various levels. That is. Reality: Decision making always involves uncertainty Even the simplest decisions carry some level of uncertainty.

In choosing a cup of coffee, there will be at least the possibility that the coffee doesn't taste good, is not hot, or will not provide the usual pleasurable feeling.
