Abstract

In our study of science, we try to make measurements and use these measurements to help us gain an understanding of the real world. In everyday life, we frequently have to make estimates of times, distances, etc., to decide, for example, whether we can catch up and board a moving bus, or whether the car that we are driving will (or will not) pass through the available gap. Usually these estimates are correct; on the other hand, if people are asked to state the height of someone they have witnessed, or state distances after a road accident, the values estimated are usually wildly inaccurate.
