Studies suggest that a large proportion of shoppers are tempted to shoplift due to the relative ease of fooling self-checkouts. For example, a person who (initially without intent to steal) does not scan an item, may remember that this was easy, and fail to scan other items deliberately.[9] A 2012 survey with 4,952 respondents in the UK found that a third of shoppers had stolen this way, with around a quarter of the remainder stating they were deterred by the risk of detection.
