What specific behaviors? Because if you're saying that we should always strive to get agreement? Yep, absolutely. I'm just saying that sometimes it doesn't really impact outcomes that much so I'd rather just have the DM make a decision and move on no matter which side of the DM screen I'm on. If you're saying the DM should never make a final call, even if some people disagree? I disagree.
Way back in the day, the DMG had truly terrible advice. Along the lines of "If your players are being overly cautious, punish their characters until they play the way you want them to." But those days are long ago and, thankfully, largely forgotten.
