We have a President who cannot accept the fact that he lost the popular vote count and that his inauguration crowd wasn’t the largest ever. Despite innumerable scientifically proved facts, such as increasing global temperatures, the massive shrinkage and loss of glaciers world-wide, the unprecedented [in the last hundred thousand years] loss of arctic sea ice, the arrival of spring weeks earlier than any time in human history, roughly fifty percent of Americans deny that global warming is caused by human activities, even though more than 97% of the 12,000 published scientific papers since 1991 on climate change recognize that the major component of rapid global warming is human caused. The Republican Party is the only major political party in the world, including all major conservative parties, that rejects the need to address global warming.
Now, this “anti-science” attitude isn’t just a conservative problem. A recent study cited by New Scientist found that a significant proportion of liberals reject published scientific findings on vaccines, genetically modified foods, and the causes of autism.
So it appears that what scientific findings people accept or reject are determined in large part by their political leanings. The problem is, however, that when roughly half the population rejects certain scientific findings, and the other half rejects others, science and rational thought end up taking a beating.
While the much-maligned John Maynard Keynes said, “When the facts change, I change my mind,” most people, when confronted with facts that contradict their beliefs, either ignore those facts or scurry to find or invent facts to support their beliefs. Donald Trump, unfortunately, follows this practice all too often.
It’s been said that science progresses one funeral at a time, but the problem today is that we’re facing problems that need to be addressed a bit more quickly than that. Part of the problem is that we’ve become a technological world, and technology multiplies everything. Benefits become vastly greater; problems do as well; and everything moves more quickly because technology multiplies the rate of change. Yet human beings are conservative by nature and by evolution, and that conservatism means we don’t respond well to rapid change, particularly change we don’t agree with, and this means our own behavior and beliefs all too often war against rational thought.
Add to that the difficulty that humans are supreme rationalizers. There’s a quote from the movie The Big Chill about the impossibility of getting through the day without rationalizing. Unfortunately, it’s getting too late to keep rationalizing about the issues of science, not without incurring extraordinarily high costs that will be passed on to our children and their children.
