Who brings the extra two opinions?
Usually, the pedants.
Or the person who is completely confused....or the person who votes twice just so they can get out of the meeting...
A major point with any safety program, though, is that communication is key and dissension is welcome. It doesn't mean that person will leave getting their way, and there comes a point when they need to realize they're outnumbered, but you don't want a safety culture where the head of your safety program makes all of the decisions for everyone. You need to have those other opinions so you don't get narrow-minded and locked in to your own ideas.
