It is also possible to overstate the prevalence of relativism outside the ranks of natural scientists, analytic philosophers, theists, and other self-consciously non-relativist thinkers.
As Michael Lynch notes in his book True to Life: Why Truth Matters, remarks that can superficially seem to be expressions of relativism might, on more careful consideration, turn out to have a different significance. For example, when, during a conversation on some controversial subject, someone says something like “Well, it’s a matter of opinion” or “Who’s to say?”, this may not be intended to imply that there is no objective fact of the matter about which view is correct. The person may instead have simply decided that the discussion has reached an uncomfortable impasse and would like to change the subject.
On the other hand, many people seem not to understand the difference between the claim that there is no agreement about such-and-such and the claim that there is no objective truth of the matter about such-and-such. Hence even many people who are primarily concerned to assert the first proposition rather than the second may nevertheless affirm the second one too if pressed. And in that case they are at least implicitly relativists. Thus, while Lynch is right that there are probably fewer self-conscious relativists than meets the eye, that is not necessarily because the people in question are all self-consciously non-relativist. Many people just have confused or inchoate ideas about these things.
