The phenomenon of “creeping normality” allows for significant changes to be deemed acceptable when they occur gradually over time, in relatively unnoticed increments, rather than single steps or dramatic and noticeable instances. The “boiling frog” metaphor, which illustrates the familiar account of an unassuming amphibian that is slowly and successfully cooked to death, reveals not only how such instances can occur, but also how a calculated and protracted alteration (produced by those with power to turn up the heat) can possess disastrous results if not noticed and properly countered (by those left in the water). We need not look far for modern-day examples.
Extreme partisanship has crept into our political normality. As revealed last year by the Pew Research Center, our civic temperature is methodically rising, perhaps beyond the boiling point. The study states:
“The overall share of Americans who express consistently conservative or consistently liberal opinions has doubled over the past two decades from 10% to 21%. [As a result], the center has gotten smaller: 39% of Americans currently take a roughly equal number of liberal and conservative positions, down from 49% in surveys conducted in 1994 and 2004.”
