Most of our society relies on majority voting or unanimous conclusions, whether it is politics, business or leisure entertainment, so people usually think that more consensus is a good thing. To some extent, this is usually the case, but sometimes the closer to unanimous approval, the less reliable the conclusion becomes. This is the so-called consistency paradox.
The consensus paradox is not all contradictory in fact, especially when people expect the smallest possible variables and uncertainties, unanimous agreement is still ideal in theory. But in practice, when it is extremely unlikely that there will be a complete agreement to reach an agreement, this tells us that there may be some hidden factors affecting the system.
Although we may strive for harmony and consensus, in many cases, mistakes and disagreements should be expected. If a perfect result seems unbelievable, there may be mistakes.
