Oxford University researchers have been looking at how we judge our own performance and that of other people. Their conclusion – we confuse the two, especially if in groups such as sports teams.
Lead researcher Marco Wittman explained: 'We judge ourselves all the time, from grades at school to how good our skills in playing football are. From a psychological-neuroscientific perspective, we know a lot about the mechanisms behind evaluating objects, but we know much less about the mechanisms that underlie the evaluation of ourselves and others.'
