In his essay On Bullshit Frankfurt writes:
The fact about himself that the bullshitter hides, on the other hand, 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 conceal it
Suppose a bullshitter is either soliciting or participating in a "let's hear from all sides" dialog, but doesn't say a word, and appears to and pretends to listen actively, but couldn't care less. The feigned "listening" is done only to perhaps:
gain the speakers trust
delay the speaker
exhaust or frustrate the speaker
run out the clock
get paid for the time spent listening
If such listening is bullshit, is there a specific name for it? If it's not bullshit, is there a theory or name for it?
Note: a silent listener does in effect make a tacit statement that they are listening, while a listener who is fidgeting, tapping, yawning, rolling their eyes, plugging their ears, watching the clock, etc. makes a contrary statement. In this respect a silent listener can therefore lie by a tacit statement contrary to their feelings. That is, by pretending indifference when interested, as with poker, or by pretending interest when bored. So this question implies the question: if a listener can tacitly lie, is it possible to tacitly bullshit as well?
