Misinformation is incorrect or misleading information.[5][6] Whereas misinformation can exist with or without specific malicious intent, disinformation is deliberately deceptive and intentionally propagated.[7][8][9][10][11] Misinformation can include inaccurate, incomplete, misleading, or false information as well as selective or half-truths.
In January 2024, the World Economic Forum identified misinformation and disinformation, propagated by both internal and external interests, to "widen societal and political divides" as the most severe global risks in the short term.[12] The reason is that misinformation can influence people's beliefs about communities, politics, medicine, and more.[13][14] Research shows that susceptibility to misinformation can be influenced by several factors, including cognitive biases, emotional responses, social dynamics, and media literacy levels.
Accusations of misinformation have been used to curb legitimate journalism and political dissent.[15]
The term came into wider recognition during the mid-1990s through the early 2020s, when its effects on public ideological influence began to be investigated. However, misinformation campaigns have existed for hundreds of years.[16][17]
