I have worked with dev's and researchers who have a very sensitive "bullshit meter" which is good a lot of the time, but often prevented me from bringing my half-baked ideas to the table. I would wait until I knew I had something solid.
I'm curious if they changed over time? I've observed this change in myself to a degree. There are things I'd not have let go in the past, but now I catch myself and evaluate the context. There is a fine balance between reducing bullshit that affects an organization and limiting the potential of the organization.
Eventually it has always improved over time in terms of others being open to my ideas. It sometimes takes awhile to develop a good reputation to be trusted.
