"... then what are the odds that only you are the one who's right?"
If this is the reasoning for people choosing the same answer then surely it becomes a question of confidence rather than conformity?
Choosing the same answer as the group in your argument is because you aren't confident in your answer and are willing to defer to the majority answer. Not necessarily the same as conformity. By your own rationing you are going with the group because you think their answer is "better" not because you want to be part of the group. I know you can argue that that is just your rationale for conformity, but I feel that conformity is more about doubting something you are sure you know, to side with a group, rather than doubting something you think you might know.
I feel possibly a more accurate test (using this reasoning for conformity) would be to take a group and tell all the members individually that only they will know the right answer. Then give all bar one the same answer and one a different answer and see if they will conform with the group.
