Many such groups are skeptical of modern medicine, science, and the government, which makes them particularly prone to health misinformation circulating through their closed communication networks and a reluctance to seek preventative and routine medical care (Arciuolo et al, 2013 ; Armer & Radina, 2006 ; Dickinson et al, 1996 ; Galanter, 1999 ; Gastañaduy et al, 2016 ; Glassman, 2018 ; Miller & Karkazis, 2013 ; Offit, 2015 ; Thompson & Kisjes, 2016 ).
