I can see and understand the pointlessness happening, which is a bit alienating when other people think they are doing hard important work and I think/know they aren't, and I need their buy in to avoid them asking me to also do things I know are pointless.
If I wanted to do pointless things (and I'm not sure I'm even capable of that) I could probably get paid a lot more by changing job, but I'd rather change my job to be less pointless, as it seems better for my mental health.
There are also some more formalised versions of the scientific process applied to the workplace. Mike Rother's Improvement Kata come to mind.
Edit: also get good at negotiation! People are complicated and refuse help even when they obviously need it. Being a good negotiator ideally helps everyone.
Second edit: another thing is leading by example. That's been very powerful in my experience.
The world is a lab. Shape it in ways which you think will prove your hypotheses false.
