What Is Cognitive Bias?

In addition to engaging in bounded rationality, an accumulating body of research tells us that decision makers allow systematic biases and errors to creep into their judgments. These come out of attempts to shortcut the decision process. In many instances, these shortcuts are helpful. However, they can lead to severe distortions from rationality. The following highlights the most common distortions. From an organizational standpoint, one of the more interesting findings related to overconfidence is that those individuals whose intellectual and interpersonal abilities are weakest are most likely to overestimate their performance and ability. So as mangers and employees become more knowledgeable about an issue, the less likely they are to display overconfidence.

Managers' ability to take a purely rational approach to decision making is hampered by insufficient information about the problems themselves, the data available, and perceptions that inhibit managers' ability to determine optimal choices. Our judgment is directed by a set of systematic biases, or heuristics. This article discusses the three broad heuristics--the availability heuristic, the representativeness heuristic, and anchoring and adjustment--and identifies the thirteen most common decision-making mistakes managers make.

Biases and Errors in Selection Decision-Making Processes

There are two types of decisions—programmed and non-programmed. A programmed decision is one that is very routine and, within an organization, likely to be subject to rules and policies that help decision makers arrive at the same decision when the situation presents itself. A nonprogrammed decision is one that is more unusual and made less frequently. These are the types of decisions that are most likely going to be subjected to decision making heuristics, or biases. As we become more embroiled in the rational decision making model—or, as we discussed, the more likely bounded rationality decision making model—some of our attempts to shortcut the collection of all data and review of all alternatives can lead us a bit astray. Common distortions in our review of data and alternatives are called biases.

Since the importance of the right decision cannot be overestimated enough for the quality of the decisions can make the difference between success and failure. Therefore, it is imperative that all factors affecting the decision be properly looked into and fully investigated. Research shows that decision makers allow biases and errors to creep into their judgments. The following highlights the most common distortions. In addition to technical and operational factors which can be quantified and analyzed, other factors such as personal values, personality traits, psychological assessment, perception of the environment, intuitional and judgemental capabilities and emotional interference must also be understood and credited.

A cognitive bias is a systematic error in thinking that occurs when people are processing and interpreting information in the world around them and affects the decisions and judgments that they make. Cognitive biases are often a result of your brain's attempt to simplify information processing. Biases often work as rules of thumb that help you make sense of the world and reach decisions with relative speed. Because of this, subtle biases can creep in and influence the way you see and think about the world.

Overconfidence Bias

Росио попробовала закричать, но в легких не было воздуха. Он вот-вот задавит. Уже теряя сознание, она рванулась к свету, который пробивался из приоткрытой двери гостиничного номера, и успела увидеть руку, сжимающую пистолет с глушителем. Яркая вспышка - и все поглотила черная бездна. ГЛАВА 40 Стоя у двери Третьего узла, Чатрукьян с безумным видом отчаянно пытался убедить Хейла в том, что с ТРАНСТЕКСТОМ стряслась беда.

Если бы вы только… - Доброй ночи, сэр.  - Кассирша опустила металлическую шторку и скрылась в служебной комнате. Беккер шумно вздохнул и поднял глаза к потолку. Успокойся, Дэвид. Спокойно. Он оглядел пустой зал. Ни души.

 Я подумала, что АНБ его ликвидировало. - Вот. Если АНБ в состоянии вывести пять риолитовых спутников на геостационарную орбиту над Ближним Востоком, то, мне кажется, легко предположить, что у нас достаточно средств, чтобы подкупить несколько испанских полицейских.  - Его доводы звучали волне убедительно. Сьюзан перевела дыхание.

 Отсюда я не в состоянии ему помочь - ему придется полагаться лишь на. А потом, я не хочу говорить по линии, не защищенной от прослушивания. Глаза Сьюзан расширились. - Как прикажете это понимать. На лице Стратмора тут же появилось виноватое выражение.

 ТРАНСТЕКСТ в полном порядке. - Вирус. - Никакого вируса. Выслушай меня внимательно, - попросил Стратмор.

Cognitive Bias: Systematic Errors in Decision Making

Акт безжалостного уничтожения. Бесчувственная демонстрация силы страной, уже добившейся победы.

Компания получает электронные сообщения, адресованные на подставное имя, и пересылает их на настоящий адрес клиента. Компания связана обязательством ни при каких условиях не раскрывать подлинное имя или адрес пользователя. - Это не доказательство, - сказал Стратмор.

Меня зовут Северная Дакота. Нуматака подавил смешок. Все знали про Северную Дакоту. Танкадо рассказал о своем тайном партнере в печати. Это был разумный шаг - завести партнера: даже в Японии нравы делового сообщества не отличались особой чистотой.

Агентство не может позволить себе еще одного скандала. Стратмору нужен был козел отпущения. Кроме всего прочего, Хейл был настоящим ходячим несчастьем, готовым свалиться на голову в любую минуту. Из задумчивости Стратмора вывел звонок мобильного телефона, едва слышный в завывании сирен и свисте пара. Не останавливаясь, он отстегнул телефон от брючного ремня.
