Mexican psychologists have long studied the traditional beliefs of Mexican families. A 2011 study in the Revista Mexicana de Investigación en Psicología lists among them “machismo, obediencia afiliativa, virginidad, abnegación, miedo a la autoridad” (machismo, affiliative obedience, virginity, self-denial, fear of authority). The psychologist Rolando Díaz-Loving summarizes one finding of this research: “self-modification coping styles are preferred over self-affirmation as guides of interaction mechanisms.”
These beliefs change over time. The 2011 study found that “unas se mantienen inalterables, mientras que otras perdieron más del 50% de apoyo” (some remain unchanged, while others lost more than 50 percent of their support).
