Now the real question is do you believe you are right? Do you really(and I mean really deep down) think these people are smart. Do you think you have a better way? Do you wish they'd realize that what you are doing is best path forward?
I have seen this sort of conversation pattern in the past. In my case it was a younger programmer that wanted the team to take a different approach, but at the same time were struggling with the "what if I'm wrong?" dilemma. They didn't want to throw their weight behind a proposed change in direction because of insecurities and fear of rejection. What it came across as to the rest of the team was a person that didn't want to lead but at the same time was always finding fault. When confronted they would say things like "I'm not one of the smart ones ..."
If you really are not smart as they are then trust them and learn from them. If you think you have a better path and are committed then stand up and say "This is wrong and here is a better way". If you are right and they reject you then maybe its not the place. If they are able to demonstrate that you are wrong you should accept it and move on. If you are right and they agree then you are in the promised land.
