![]() ![]() Based on this likelihood, the chances of the girl having a PhD become much smaller. Namely, that there are much more people riding the metro that do not have a college degree. Due to stereotyping because she reads the New York Times, we would probably judge her to have a PhD.īut this doesn't take the base-rate into account. Bet on her having a PhD or not having a college degree. And it happens all the time.Īnother example is a girl that is sitting on the metro and reading the New York Times. This cognitive bias that we fail to see through is part of how our mind reacts and responds to daily life. ![]() Based on percentages, the chances of Steve being a farmer are actually higher than being a librarian. We fail to take into account that for every librarian there is a much bigger number of farmers with this description. But the mistake, as Daniel Kahneman explains, comes from the image we hold in our minds. Is Steve a librarian or a farmer? Most people would answer a librarian. His description is that he is mild-mannered and detail-oriented. This bias implies that we forget or ignore the frequency of some event occurring, by ignoring important data (What You See Is All There Is). It is the constant search of validation for what we believe to be true.Īm I trying to reinterpret things to maintain a previous attitude or belief?Īm I overvaluing evidence because of my own experience?Īm I seeing a pattern where there isn’t one? The Base-rate neglect they will keep close track of instances where they thought of their mother and then 3 seconds later the phone rang with their mother calling. For example, people that believe in ESP (Extra-Sensory Perception) think they can perceive and sense things with the mind. Facts are interpreted in a biased way, leading us to only uphold information that aligns with what we think already. The Confirmation bias is deeply rooted in our opinion of what we think of the world. It is selective perception of information - meaning that what we seek to see is what we believe already. The Confirmation bias implies that new information is always made compatible with existing beliefs we have about the world. Substitution simplifying the question to create an answer.The Rush effect using the wrong system to answer a question.The Framing effect seeing identical choices as different choices.Base-Rate neglect ignoring evidence / undervaluing statistics.The Confirmation bias interpreting new information as confirmation of our beliefs.Here are five types of biases that are widely spread in daily life. This implies that decisions are made with some type of information, even though the information itself isn't always correct. The mind only takes and evaluates the things it knows, not the things it doesn't know. This is because the mind can construct quite an illogical, inaccurate, incomplete or unreliable story - but as long as it sees it as coherent it will accept it.ĭaniel Kahneman in his book Thinking Fast and Slow calls this "What You See Is All There Is" (acronym is WYSIATI). Cognitive biasesĬognitive biases can arise from low availability of information, incorrect perception, or when we use mental shortcuts to come to a conclusion. In this article you will discover cognitive biases and effects of the environment that influences your decisions in daily life. This can be due to cognitive bias, or there is an environmental influence affecting our emotional state and thus our decision. System blind spotsīlind spots can lead to incorrect decisions. This system requires more effort but it is also more reliable than system 1. Answering difficult equations such as 27x42, or extensively thinking through a problem with a high level of concentration. It is based on logical thought and complex problem solving. System 2 is the slower and deliberate thinking system. It is also the system that is responsible for answering simple equations such as 2+2. Based on our emotions and feelings, it helps us guide our everyday decisions. System 1 is the fast instinctive and unconscious way of thinking. This means that if we can be conscious of them, we can start making smarter decisions. These errors are part of a systematic pattern. But there are also cognitive errors in our mind that lead to irrationality and inaccurate judgements. Thinking Fast and Slow In the book Thinking Fast and Slow, Daniel Kahneman mentions two separate systems that we use to make decisions - fast and slow thinking. ![]()
