Bullying is an unfortunate but enduring aspect of many pupils' school experience. In this episode, we look closely at the psychological phenomenon of 'the bystander effect' and what, if anything, we can do to create a culture of 'up-standers' instead. I draw from my two-year study of 'everyday heroism' and suggest four competencies which, if purposefully developed as part of the curriculum, can turn the tide and create a community founded on compassion and acceptance of difference.
