These explanations range from impulsive behavior due to the Id or simply following orders to steal shipwrecked goods from an authority figure who gave the order to do so . However, most of the evidence supporting these explanations have their weaknesses, for example social learning theory, a theory based on the study by Bandura et al. was conducted in an artificial laboratory environment, so has low ecological validity and consequently we cannot be certain whether these findings would be relevant in an everyday context. There are also personal reasons why someone may steal shipwrecked goods. As a result, there are various explanations as to why someone would take shipwrecked goods, one of them being that the goods are no longer owned by anyone else and therefore can be claimed by an individual as their own property.
