Status quo bias is cognitive bias for the status quo; in other words, people like things to stay relatively the same.

The finding has been observed in many fields, including political science, economics and question framing .

Kahneman, Thaler and Knetch created experiments that could produce this effect reliably. They attribute it to a combination of loss aversion and the endowment effect, two ideas relevant to prospect theory. The US states of New Jersey and Pennsylvania inadvertently ran a real life experiment providing evidence of the status quo bias in the early 1990s. As part of tort law reform programs, citizens were offered two options for their automotive insurance - an expensive option giving them full right to sue and a less expensive option with restricted rights to sue. Each of the options was roughly equivalent to the other. In New Jersey the more expensive option was the default and 75% of citizens 'selected' while only 20% chose this option in Pennsylvania where the other option was the default.
