Normalcy Bias: Definition, Examples and Effects

Normalcy bias is a cognitive bias that causes people to underestimate the likelihood of a disaster or other catastrophic event occurring. It is a form of cognitive dissonance that leads people to believe that, since a disaster has not occurred in the past, it is unlikely to occur in the future. This bias can lead to a false sense of security and can have serious consequences if it causes people to ignore potential threats.


Definition: Normalcy bias is a cognitive bias that causes people to underestimate the likelihood of a disaster or other catastrophic event occurring. It is a form of cognitive dissonance that leads people to believe that, since a disaster has not occurred in the past, it is unlikely to occur in the future.


Examples: One example of normalcy bias is the belief that a natural disaster, such as an earthquake or hurricane, will not occur in a particular area. Another example is the belief that a terrorist attack will not occur in a particular city or country.


Effects: Normalcy bias can lead to a false sense of security and can have serious consequences if it causes people to ignore potential threats. It can also lead to complacency and a lack of preparedness for disasters or other catastrophic events. Additionally, it can lead to a lack of awareness of potential risks and a lack of action to mitigate those risks.
