Once we looked for answers through divination, now science can forecast significant events such as the onset of certain hereditary disease. But the fact that some people choose not to know – even when information is accessible, and has a bearing on their lives – has encouraged scientists, including Gerd Gigerenzer and Rocio Garcia-Retamero, to try to map out the limits of our appetite for knowledge. Their recent study in Psychological Review suggests that it is a fear of what we might discover – and wishing that we’d never known – that often drives us to deliberate ignorance. Gigerenzer, Director of the Max Planck Institute for Human Development, and Garcia-Retamero at the University of Granada, asked nationally representative samples of participants in Germany and Spain whether they would be willing to know the date or cause of their own or their partner’s death; whether their marriage would end in divorce; as well as information relating to positive future events like knowing the gender of their unborn child, or what was in store for them under the Christmas wrapping paper.
