The very manner of "scientific method" displayed by Hubbard in his works has indeed been called "anti-science," in that the claims made in the books are based not on peer-reviewed observation of phenomena, with its attendant blind testing, control groups etc., but rather on deciding a priori that a phenomenon exists–followed by an attempt to prove its validity.

By assigning its pursuit to the desire to predate Jewish national claims, he describes Canaanism as a "losing ideology", whether or not it is factual, "when used to manage our conflict with the Zionist movement" since Canaanism "concedes a priori the central thesis of Zionism. Namely that we have been engaged in a perennial conflict with Zionism—and hence with the Jewish presence in Palestine—since the Kingdom of Solomon and before ... thus in one stroke Canaanism cancels the assumption that Zionism is a European movement, propelled by modern European contingencies..."
