Editorial: Challenging injustice: Understanding upstanding, civic action, and bystander intervention to promote justice

Throughout history, individuals and communities have come together to challenge injustice in the local community and across the globe. In recent years, we have seen communities rally together to advocate for changes in policy and practice to address injustices faced by marginalized and disenfranchised groups of people. For instance, communities have taken action through the Movement for Black Lives in the United States, the women's uprising in Iran following the death of Mahsa Amini, and the pro-democracy protests in Hong Kong. These challenges to social injustices are not only led by adults. Rather, youth engage in civic action to amplify the voices of those who are marginalized, isolated, or victimized and frequently organize to protest injustice and foster collective action through social media or other technology. These challenges to injustice often arise from community-led efforts, rooted in the unique contexts and histories of the local community. This special issue considers challenging injustice broadly to include bystander intervention in instances of bullying, harassment, or aggression, political and civic engagement, anti-racist or anti-oppression activism, and resistance to injustice in institutions and communities. Three overarching themes are featured in this special issue: (1) work examining bullying experiences and factors that motivate bystander intervention in response to bullying; (2) scholarship exploring identity, socialization, and critical action and (3) research focused on collective action and challenging inequalities.
