Despite these criticisms, Murray was invited to write the entry on "witchcraft" for the 1929 edition of the "Encyclopædia Britannica", which was reprinted for decades, last appearing in the 1969 edition. Rather than write an article that reflected the historical consensus on the witch trials, Murray used the opportunity to promote her own hypothesis in the "Encyclopædia", presenting it as fact. It was so influential that, according to folklorist Jacqueline Simpson, Murray's ideas became "so entrenched in popular culture that they will probably never be uprooted."
