Tried-and-tested for multiple years, WTF Diamonds are eye-catching formations that resemble art installations. Everything from the way people stand to the masks and screens on display is carefully designed to cause intrigue and attract attention. This event format is a catalyst to the important part: the conversations that follow.

Having experimented with various event formats for the past 4 years, early evidence suggests that the WTF Movie Challenge event format is most likely more effective. This is due to activists regularly reporting more conversations and a higher percentage of effective conversations. This is backed up by the data we've collected, but it's too soon to say for certain.

For this reason, we are currently recommending that teams prioritise the Movie Challenge. However, what we don't yet know is how different demographics might react or be impacted by the different formats. For example, are there certain age groups or gender identities that are more likely to take the movie challenge over the diamond? We don't know yet. For this reason, it's totally fine if you or your team wants to prioritise one or both event formats.
