The ostrich effect, also known as the ostrich problem,[1] was originally coined by Galai & Sade (2003).[2] The name comes from the common (but false) legend that ostriches bury their heads in the sand to avoid danger. This effect is a cognitive bias where people tend to “bury their head in the sand” and avoid potentially negative but useful information, such as feedback on progress, to avoid psychological discomfort.[1]
