Recently, a reader made an interesting comment to the effect that what I personally believed to be true doesn’t necessarily turn out to be true for others. This is a statement that initially sounds very reasonable, and studies indicate that it’s something that most people believe.

But… it’s also incredibly deceptive and dangerous. Now, I may have been correct, or I may have been incorrect. I may have had my facts wrong, or perhaps they were right. But the idea that correctness, accuracy, or “the truth” of something varies from individual to individual, depending on individual perception, is a very dangerous proposition.

Part of the reason why that proposition is dangerous is the use of the word “truth.” The word “truth” embodies a connotation of moral purity and certainty on the part of the individual defining that truth. On the other hand, facts are. How they’re perceived by individuals obviously varies, and different individuals give different weight to the same set of facts. Different individuals cite different sets of facts in support or opposition to policies, proposals, books, laws, or in other settings. But the bottom line should always be based on whether the facts are indeed accurate, and whether they apply to the situation at hand, not upon my beliefs about them or someone else’s beliefs about them.

It appears to me that today we’ve gotten into a societal mindset that places what we feel about anything far above determining what is accurate, what is actually so, and what is not. As feeling beings, this tendency has always been a great part of being human, but one of the great drivers of the advancement of human civilization has been the effort to determine verifiable facts, workable scientific theories based on replicable experiments and solid facts, as opposed to belief based on what cannot be determined to be accurate.

Yes, scientists and true empiricists have beliefs, but they try [and sometimes fail] to base those beliefs on hard evidence.

I’m not dismissing the importance of belief. Every human being needs things or ideals in which to believe, but the idea that what is “true” for one individual is not for another puts individual perception above accuracy and tends to support the idea that each set of beliefs is as valid as any other set of beliefs, when time and history and science have shown that “truth” resides far more often in what can be accurately determined and verified than in what cannot.

Despite the fact that in the third century BCE the Greek astronomer Aristarchus of Samos had presented a proof that the Earth revolved around the sun, more than 1500 years later the Christian Church was burning as heretics those who stated that the Earth was not the center of the universe and that it revolved around the sun. The “moral certainty” of faith trumped the facts, at least until science advanced to the point where the proof was irrefutable.

We’ve now reached a point where individuals realize that they must have at least some facts to support the “truth” of their beliefs… and in welter of “information” that surrounds us, too many individuals pick inaccurate or inapplicable facts in order to support their beliefs.

The idea that truth of belief varies from individual to individual is actually an accurate statement of a dangerous proposition – that “individual truth” is superior to verified evidence and facts, when, in fact the converse should be what we all strive for, that verified evidence and facts support our beliefs, rather than having our beliefs force us to find facts to support those beliefs.

Yet recent study after recent study shows that the majority of people tailor their facts to support their beliefs, rather than using verifiable facts to change their beliefs. Will we revert to faith over facts, as did the Christian Church of the 1500s? Given what I’ve seen over the last few years, it’s anything but an unreasonable question.
