The more times we have walked a route, the longer we judge it to be, a UK researcher has confirmed. His studies could help explain why daily commutes can grow to seem interminably long. Neuroscientists have long known that our brains are poor at estimating a set distance such as a kilometre. But most studies of this phenomenon have been carried out in simple artificial environments where, for example, people walk along paths taped out in a gymnasium.
