Laird Wilcox in "Who Watches the Watchmen?" has criticized Berlet and other writers for what Wilcox says is their use of a technique he describes as "Links and Ties," which he says is a form of guilt by association. Commentators have alleged that Berlet himself uses the methods of conspiracy theorists. Wilcox and John George opine that Berlet "comes from extremist ranks," citing his activity in the National Lawyers Guild. Berlet has responded with his belief that Wilcox is attempting to discredit his competition.
