Julie Vander Meulen, a former researcher turned empowerment coach and founder of Own Your Life Academy in Brussels, Belgium, established Good Girl Syndrome Awareness Day and held its first observance on October 22, 2025, as part of her broader movement to name and address the behavioral conditioning she calls Good Girl Syndrome.
The research that documented the pattern
In 1982, Harvard psychologist Carol Gilligan published the landmark book In a Different Voice. Her research showed that many girls begin suppressing their authentic thoughts and opinions around age 11 in response to social expectations.
Gilligan's work revealed a troubling developmental shift: confident, outspoken girls often become self-doubting adolescents as they learn that honesty can threaten belonging.
Her findings created the academic foundation for understanding gendered self-silencing.
