👉 Pronationalism is a philosophical concept in psychology that suggests that people's attitudes, behaviors, and perceptions are primarily influenced by their first language or mother tongue. It was developed by American psychologist Stanley Milgram in his study of human behavior under stress, where he observed that children who were raised in English-speaking families had more negative attitudes towards authority figures than those from other languages. This concept is often associated with the idea that people's beliefs and values are primarily shaped by their first language or mother tongue
