Beliefs based on truth don't need social reinforcement and don't need to be 'believed by others' due being self-evident. Whose truth? Many people will tell their beliefs are based on truth, even people with conflicting beliefs will both defend their viewpoints by claiming "truth". Your assumption that all truths are self-evident (or that all instances of self-evidence are truths) seems invalid to me.
