The first thought that came to my mind is related to the other post on this forum about psychedelics.
My interpretation is therapeutic psilocybin experiences can create a feeling of all being part of the same team / global interconnectedness. I wonder if this would lead to less tribalism. It seems like it very well may.
“In 6-month follow-up interviews, participants were asked: ‘Did this treatment work for you, and if so how?’ and responses were analysed for consistent themes (Watts et al. 2017). Of the 17 patients who endorsed the treatment’s effectiveness, all made reference to one particular mediating factor: a renewed sense of connection or connectedness. This factor was found to have three distinguishable aspects: connection to (1) self, (2) others and (3) the world in general (Watts et al. 2017).”

I would worry that the “feeling of all being part of the same team” could just as likely lead to more tribalism as to less. It’s a question of who “all” refers to. Reminds me of discussions around empathy and compassion–if our other-regarding behaviors are strengthened toward those close to us, it can actually make us worse to those further away (even if only because of resource constraints).
