I also think not a hope, check Brandolini's law[1]: The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it.
There should be a countervailing law that the more bullshit is produced the more skeptical the populace becomes. The amount of conspiracy theorists has remained constant even with the advent of the Internet this hasn't changed.
