After the disaster of Hurricane Katrina in 2005, many people come forward and said that they knew that the levees in New Orleans should have been built stronger, and that they just knew that a catastrophe like this was coming. In research this is known as the________.

Hindsight bias : This can be defined as a situation whereby a person forecast the consequence of an event that could happened in the future which eventually happened exactly the way the person had forecasted the event . When an event had occurred, people tend to have the habit of saying that,they knew the consequences of the event happening before it eventually happened. This concept is applicable in the areas of sport for example when someone forecast that his football team is going to beat their opponent by two goals to one and it eventually happened the way the person had predicted it. It can also be applicable in the areas of politics, for example when someone had forecasted that the candidate for their party in the forthcoming election will win the election by a wide margin to beat the other contestant in the election, and it happened exactly the person had predicted it. Therefore, in the event described in the question, the research is known as hindsight bias.
