In short, no, it does not. First off, tiered medicine places different types of knowledge in a hierarchy. Consensus is always above those positions that are against consensus or unknown. Also, under this model, one does not have the liberty to adopt positions contrary to the consensus that would also potentially pose a large health risk for the individual or those around them. So, for example, being against the MMR vaccination would not fit under this model of medicine, since this could potentially be a huge health risk both to the individual and to others.
