A new four-part HBO series, "Allen v. Farrow," documents the accusations of sexual abuse against film director Woody Allen and the aftermath. The documentary calls on the expertise of Joan S. Meier, a professor of law at George Washington University Law School. In the docuseries Meier comments on strategies of disinformation used by abusers, and references her research focusing on a particularly widespread one: the claim of "parental alienation" often used to deny abuse claims by women and children.
