This case demonstrates how communications can spark a national conversation about the readiness of young men to intervene against misogyny. The core idea of this multi-phase campaign was to encourage young men to ‘Have a word’ (‘Maaate!’ was suggested) to intervene against misogynistic behaviour among their peer group. The campaign used partnerships with comedian Romesh Ranganathan, LADbible, and Transport for London, and a film where viewers pressed the ‘Maaate’ button for one of 270 possible outcomes. Evidence communications worked includes its impact on social conversations and in earned media, and post-campaign attitudinal and behavioural shifts in the target audience.
