“Reality is that which continues to exist even when you stop believing in it.” ~ Philip K. Dick
Why Is Scientific Illiteracy So Acceptable?Lawrence M. KraussIn the mid-1980s, when I taught a Physics for Poets class at Yale University, I was dumbstruck when I gave the students a quiz problem to estimate the total amount of water flushed in all the toilets in the US in one 24-hour period and I started to grade the quiz. In order to estimate this, you have to first estimate the population of the US. I discovered that 35 percent of my Yale students, many of whom were history or American studies majors, thought the population of the US was less than 10 million! I went around campus interrogating students I met, asking them what they thought the population of the US was. Again, about one-third of the students thought it was less than 10 million and a few even thought it was greater than a few billion.
How was such ignorance so common in a community commonly felt to contain the cream of the crop of young US college students?
Then it dawned on me. It wasn’t that these students were ignorant about US society. It was that they were rather “innumerate,” as the mathematician John Allen Paulos had labeled it in a book he wrote in the 1980s. They had no concept whatsoever of what a million actually represented. For them, a million and a billion were merely both too large to comprehend.
It remains a badge of honor for many who like to describe themselves as highly cultured or artistic to describe themselves as mathematically challenged, or to say that their brains aren’t wired for mathematics. Because many of those they hold in high esteem have made similar claims, there is no real social penalty to them for doing so.
When it comes to science rather than mathematics, it isn’t so simple. Proudly proclaiming scientific illiteracy is not de rigueur. Instead another refrain has recently become popular among politicians and public figures: “I am not a scientist, but…” Equally prominent, is the statement “I believe in science” (as if there is a choice) which is then followed by some scientific gibberish.
Science fiction writer Philip K. Dick once said, “Reality is that which continues to exist even when you stop believing in it.” The line between being scientifically or empirically controversial vs being politically controversial has been blurred to the point of erasure. In Washington, and many other seats of government throughout the world, belief trumps reality.
Different aspects of the problem were on display recently during the confirmation hearings of Amy Coney Barrett. When asked by Louisiana Sen. John Kennedy about her views on climate change, she said: “You know, I’m certainly not a scientist,” and added, “I have read things about climate change—I would not say I have firm views on it.” Later, following questions from Kamala Harris about whether she acknowledged a relationship between smoking and cancer, and whether the coronavirus is infectious, both of which she answered in the affirmative, she was asked, “And do you believe that climate change is happening and is threatening the air we breathe and the water we drink?” Coney Barrett responded, “I will not do that. I will not express a view on a matter of public policy, especially one that is politically controversial…”
It would have been appropriate for Justice Coney Barrett to argue in both cases that ...
