What is smarm, exactly? Smarm is a kind of performance—an assumption of the forms of seriousness, of virtue, of constructiveness, without the substance. Smarm is concerned with appropriateness and with tone. Smarm disapproves.
Smarm would rather talk about anything other than smarm. Why, smarm asks, can't everyone just be nicer?
Bullshit, Frankfurt wrote, was defined by the bullshitter's indifference to truth:
"The fact about himself that the bullshitter hides...is that the truth-values of his statements are of no central interest to him; what we are not to understand is that his intention is neither to report the truth nor to conceal it."
"The bullshitter may not deceive us, or even intend to do so, either about the facts or about what he takes the facts to be. What he does necessarily attempt to deceive us about is his enterprise. His only indispensably distinctive characteristic is that in a certain way he misrepresents what he is up to."
Smarm should be understood as a type of bullshit, then—it expresses one agenda, while actually pursuing a different one. It is a kind of moral and ethical misdirection. Its genuine purposes lie beneath the greased-over surface.
