 Subsequently, many studies have described Nagualism in different Mesoamerican cultures such as the Zoques and the Jakaltek, K'iche', Q'eqchi', and Tzeltal Maya.Among the Jacaltek, "naguals" reinforce indigenism by punishing those who collaborate with non-indigenous ladinos".In 1955, Gustavo Correa suggested Nagualism is not pre-Columbian, arguing that it was wholly imported from Europe, where he compared it to the medieval belief in werewolves.
