In most interactions, we take a defensive posture. We try to defend or position. The problem with defense is that it's static and time consuming. The best way to get smarter, is to first embrace an idea and then replace. Think about how you could take a scientific approach/method to such interactions.
Ask yourself, "what do I believe that's wrong? How can I change the way I do things? How are others doing things? What is their position? What works? What doesn't?"
If you enter a conversation looking for something to test, measure, and change, you will find it - probably much more. On the other hand, if you enter a conversation concerned about maintaining the status quo, it's likely that this is exactly what you're going to do. Be scientific with your approach, this will position you to keep the cheap talk at bay. Beware, it is easy to poke holes but takes more effort to build a position.
How to recognize an ineffective opposition? The screaming is a key part, because screaming is often a tool used to balance out the ignorance of someone parroting opposition to an idea that they don't understand. It's essential that you know more about the topic at hand than everyone else, not less. Be skeptical, but be informed. Screaming ignorance gets attention, but it distracts us from the work at hand.
If you want to change what your tribe believes, or the strategy your company is following, the first step is to get smarter and be the best informed person in the room. Take a scientific approach for your ideas and this will position you to get your ideas heard; even if you are the quiet member.
Thank You for listening.
