First, the distinction made between persuasive and evasive bullshitting strikes me as vacuous. Evasion is a species of persuasion so it's not two types, but rather a contains relation. On to bullshit then. Harry Frankfurt wrote an entertaining little book on the subject[1]. To boil it down, the liar is concerned with the truth, but makes it serve his ends by hiding it. On the other hand the bullshitter is concerned with persuasion and gives no particular consideration to the truth value of his claims, so long as they persuade. As such well-crafted bullshit is designed to sound plausible and elicit the sensation of truth. For example, someone running a pump and dump scheme with a stock is liable to be bullshitting. The reasons he gives for buying may well be true, but he doesn't care either way so long as the rubes drive his shares up.
