I don't know.
People often *agree* for the sake of agreeing. I'd say that's more characteristic of human nature.
Ever heard of "groupthink" that's the idea that groups tend to very quickly agree on a certain course of action, even if its the wrong course of action, and that group members choose consensus rather than disagreement, bc it feels better to be in agreement rather than discord.
So, I guess in answer to the OP I think a strong case could be made for a definitive "NO".
