Cult leaders will often radically change these narratives for no apparent reason, forcing their cult members to abruptly forswear (and often even denounce as “heresy”) the beliefs they had previously been forced to profess, and behave as if they had never believed them, which causes their minds to further short circuit, until they eventually give up even trying to think rationally, and just mindlessly parrot whatever nonsensical gibberish the cult leader fills their heads with.
