The vast majority of people believe what they want to. What distinguishes a thinking individual from a believing individual is that thinking individuals do their best to evaluate all the facts in their environment and in the universe, not just the ones that support what they believe. What complicates this is that some individuals believe in things that are so; that is, what they believe is aligned with what the facts indicate is in fact so, but they do so out of belief, and often the basis for those beliefs rests upon other biases not grounded in fact. Add to that the fact that someone can be a thinking individual in some respects and a total “believer” in something that is anything but grounded in fact in others. In life, most of us are a mixture of thinker and believer.
From what I’ve observed and from what some psychologists report, all too often when “loyalties” that require adherence to a belief ungrounded in fact [and by that I mean the preponderance of fact and not just selected facts] conflict with the preponderance of fact, loyalties almost always win out. Thus, a far greater number of Republicans believe President Obama is a Muslim than do Democrats, while a far greater number of liberals oppose all genetically modified foods than do conservatives. Extreme fundamentalist Christians cannot accept evolution because it conflicts with an essential loyalty. Extreme libertarians believe that minimal or no government secures the most freedom for the most people, despite the bloody evidence of all human history to the contrary.
What makes all this even more of a problem is that when one marshals even what might seem an unassailable array of facts and proof against a belief with little or no support grounded in reality, all such an assault does, in the vast majority of instances, is to strengthen the belief. Which is why a small army of self-proclaimed and armed militia members continue to patrol the side-roads around Bunkerville, Nevada, most firmly convinced that Cliven Bundy, the man who owes the federal government [i.e., the taxpayers] over a million dollars, is a patriot supporting states’ rights, in particular rights that the state of Nevada relinquished in writing upon gaining statehood, and rights that are superseded in writing in the Constitution, that very document those true-believing militia types insist they are upholding.
But then, how many of us have beliefs ungrounded in fact and reality that we uphold against the evidence all around us, evidence we choose not to see because it conflicts with what we need to believe?
