Vaughn R. Walker, Perry v. Schwarzenegger — 6:Credibility Determinations--Plaintiffs' Witnesses (2010)
“ Letitia Anne Peplau, a psychologist, was qualified as an expert on couple relationships within the field of psychology. Peplau offered four opinions: (1) for adults who choose to enter marriage, that marriage is often associated with many important benefits; (2) research has shown remarkable similarities between same-sex and opposite-sex couples; (3) if same-sex couples are permitted to marry, they will likely experience the same benefits from marriage as opposite-sex couples; and (4) permitting same-sex marriage will not harm opposite-sex marriage. ”
