"There is a word for this kind of communication, one the philosopher Harry Frankfurt famously employed back in 1986, when he wrote a short essay called On Bullshit. Frankfurt’s central observation, which has aged terrifyingly well, is that the bullshitter is not the same as the liar, because the liar at least respects the truth enough to try to hide it, but the bullshitter does not care whether what they are saying is true or false. The truth-value of the statement is simply not part of their concern. The bullshitter is optimising for a different objective, usually appearing competent, appearing confident, or appearing to be the right kind of person to be in the room. And precisely because the bullshitter is indifferent to truth, Frankfurt argued, they are a greater threat to honest discourse than any liar. Twenty years on, that essay reads like a pre-mortem on the modern internet and, in parts, modern society."
