Discuss how the illusion of control bias affects an individual’s perception of their power over uncertain events, and provide a case study where this was used to influence behavior.

The illusion of control bias is a cognitive bias where individuals tend to overestimate their ability to control events that are largely determined by chance or external factors. This bias leads people to believe they have more power over uncertain situations than they actually do, often resulting in behaviors that are illogical or irrational. It’s rooted in a human desire for predictability and control over our environment, even when that control is minimal or non-existent. The cognitive processes behind the illusion of control stem from the human tendency to seek patterns and structure, even when none exist. We attribute causality to our actions even when there’s no direct connection and often mistake correlation for causation. For instance, people often feel that their actions, no matter how irrelevant, have some impact on random events, even if they are totally disconnected. This is due to a basic human desire to feel like we are in charge of our own lives and have the ability to steer our outcomes and that we are not merely at the mercy of chance. This belief, however incorrect, makes us feel safer and more secure.

One aspect of this bias is our tendency to focus on actions that have worked in the past and generalize them to all situations, even if the situations are not exactly the same, and even if success was due to luck rather than skill. In fact, people tend to be much more confident of a particular outcome, if they have an active role, no matter how small, than if they are passive. This is part of the reason why lottery tickets are so popular; the act of choosing the numbers yourself makes it seem that you have more control over the outcome, even though the odds are always the same, regardless of what numbers you pick.

Another key aspect is the overestimation of skill versus luck. If people are successful, then they will attribute it to skill, even if it was pure luck. If they fail, they are much more likely to attribute it to bad luck rather than their own lack of ability or preparation. This bias makes them overconfident in their abilities, even if they are not particularly skilled. This also creates the illusion of control since you are more likely to think that your actions can affect the outcome, when they often cannot.

A compelling case study where the illusion of control bias was used to influence behavior is the use of pedestrian crossing buttons at traffic intersections. In many locations, the pedestrian crossing button is actually a placebo. The button is there, but it is often not connected to the traffic signals, or at least does not have an effect that is noticeable. When people press the button, they perceive it as shortening the wait time. This is often not the case, but people tend to feel like they have had more control over their situation, simply by pressing that button. This feeling of control tends to reduce frustration and anxiety and will make people more patient. The button does nothing to the wait time, but it makes people less anxious about waiting, and this results in a better experience. They are still waiting the same amount of time, but they are under the impression that the act of pushing the button has done something to influence the outcome, making them feel like they are not just at the mercy of chance.

Another example that can be used to illustrate this point is the use of a "door close" button in elevators. Many people will repeatedly press the close button, even though the doors close automatically, which will not be sped up by pressing the close button. However, this act will give people the illusion of control, making the waiting process seem faster, and making them feel less anxious and less frustrated. This is also true for thermostats. If someone is too cold, they might turn up the thermostat to a very high setting, and even though the thermostat will still take time to warm up the room, the act of setting it to a high temperature gives them an illusion of control, which will make the cold feel less unbearable, even though they are no warmer than if they set the thermostat at a reasonable temperature.

The illusion of control can be a powerful tool, that can be used to affect human behavior. However, it is essential to remember that while the illusion of control can be beneficial for a psychological well-being, it can also lead to false beliefs and risky behavior. Understanding this bias is key to making more rational decisions and also knowing when we are being manipulated.
