True ignorance is not the absence of knowledge,
but the refusal to acquire it.
— Karl Popper
I rarely encounter a fatuous opinion that's based on knowledge.
They're almost always based on bullshit.
Knowledge has never been as easy to acquire than it is today.
And yet ignorance remains rampant.
Our polity is a disaster today because, while we test citizens relentlessly—for Covid-19, alcohol, cholesterol, illegal drugs, math skills and driving skills—we don't test our citizens for ignorance.
We let it go unchecked.
People who are ignorant counter knowledge by labeling it opinion, as if there were no difference.
"Well, that's your opinion."
But there's a vast difference, which has been understood for 2,500 years.
The Ancient Greek philosophers called opinion doxa; knowledge, episteme.
Episteme, the philosophers taught, had privilege over doxa because it was rational (or what we'd call "evidence-based").
To label episteme as doxa—to say, "Well, that's your opinion"—is to conflate the two forms of knowledge.
In short, to pile ignorance on top of ignorance.
But some ignorant people want to double down even on that.
Insisting there's fake news is worse than ignorant; it's psychotic.
It's the cranial condition Karl Popper described as "true ignorance."
Ignorance that won't seek self-help.
But that's nothing new.
"The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that my ignorance is just as good as your knowledge."
