It's not obvious that a bullshitter is "probably worse" than liars. Just because a bullshitter didn't care to research whether some vitamin pill meets marketing claims doesn't mean they're mentally volatile or psychotic. It's a bit of a leap to go from bullshit to asking whether a person lives in the same reality as everyone else.

Liars (humans) are often unconcerned with facts or truth either. More often these days, they are only concerned with profit. Are unconfirmed lies in the pursuit of mere profit somehow not lies?
