It is more difficult to test for hindsight bias in children than adults because the verbal methods used in experiments on adults are too complex for children to understand, let alone measure bias. Some experimental procedures have been created with visual identification to test children about their hindsight bias in a way they can grasp. Methods with visual images start by presenting a blurry image to the child that becomes clearer over time. In some conditions, the subjects know what the final object is and in others they do not. In cases where the subject knows what the object shape will become when the image is clear, they are asked to estimate the amount of time other participants of similar age will take to guess what the object is. Due to hindsight bias, the estimated times are often much lower than the actual times. This is because the participant is using their personal knowledge while making their estimate.
