Having spent many years of my life as a then-evangelical pastor attempting to change minds on things like women, climate change, evolution (and at the very end, LGBTQ) I’m inclined to think what matters more is helping people who already agree to speak up, be active, work for change. The reasons that people hold to positions despite evidence are deeply rooted in their social contexts, owing to our desperate need to maintain belonging in our groups. The percentage of people willing to threaten their belonging to their groups/churches/family systems, etc (or take any social risks) is quite low. This is especially the case in progressive circles where many tend to think that having the correct viewpoints (and voting) is all that is needed. Conservatives and traditionalists are, I think, much more willing to attend school board meetings, etc to speak up for their views and in recent years have out-organized those with progressive views. Perhaps this is changing now.
