Liberals are constantly demanding that we “believe the science.” I’m all for that. But the problem is “the science” changes, often quickly. Worse yet, what some want to call science is increasingly politics masquerading as science. And nothing has demonstrated that better than the coronavirus.

Consider House Speaker Nancy Pelosi (D-Calif.). In an April press conference discussing the coronavirus pandemic she said, “If you don’t believe in science and you don’t believe in governance, that is their [Republicans’] approach.”

Sen. Bernie Sanders (I-Vt.) said last March that the Trump White House “has shown the world that it does not believe in science.”

And let’s not overlook Democratic presidential nominee Joe Biden. On May 19 he tweeted, “We need a president who believes in science.”

These “believe the science” scolds are little more than thinly vailed efforts to attack conservatives who ask reasonable questions. They also convey a sanctimonious intellectual superiority over anyone who challenges the left.

But demands that we believe the science raise the question: Which science are we supposed to believe?
