This chapter focuses on how it is possible to develop and retain false beliefs even when the relevant information we receive is not itself misleading or inaccurate. In common usage, the term misinformed refers to someone who holds false beliefs, and the most obvious source of false beliefs is inaccurate information. In some cases, however, false beliefs arise, not from inaccurate or misleading information, but rather from cognitive biases that influence the way that information is interpreted and recalled. Other cognitive biases limit the ability of new and accurate information to correct existing misconceptions. We begin the chapter by examining the role of cognitive biases and heuristics in creating misconceptions, taking as our context misconceptions commonly observed during the COVID-19 pandemic. We then explain why accurate information does not always or necessarily correct misconceptions, and in certain situations can even entrench false beliefs. Throughout the chapter, we outline strategies that information designers can use to reduce the possibility that false beliefs arise from, and persist in the face of, accurate information.
