Also, do you trust the scientists? Or the scientific establishment that decides what practitioners rise to the level of being trustworthy?

Yes.

I've found most of the people who don't trust don't want to trust, not they actually don't trust, because they know nothing about the bodies that establish this, the standards they hold, specific issues that cause their loss of trust. Zero real background.

What actual bodies that establish credibility/verification do you currently not trust? What examples of their failures prompted you to stop trusting them or even be interested in the topic of if they were trustworthy gatekeeps? Most of the time that answer ends up having personal politics as the root, not actual trust issues that actually occurred and got the doubters attention. Normally if they have any examples they are politically sourced/politically generated laundry lists, not authentically generated concern or personal knowledge/care of the topic past wielding as a political weapon.
