The Secret VS The Immortal Life of Henrietta Lacks
Verdict DROP IT BUY IT
The Reality The book's philosophy had a real, documented, tragic test case. Kim Tinkham, diagnosed with breast cancer shortly after appearing on Oprah's Secret-themed episodes, publicly announced she was forgoing chemotherapy to rely on the book's Law of Attraction philosophy, combined with an unrelated 'pH Miracle' alkaline-diet regimen with zero reliable scientific support. Oprah brought Tinkham back on air specifically to urge her not to 'ignore all the advantages of medical science.' The Law of Attraction itself has no basis in physics or medicine recognized by mainstream science, and Tinkham's case became a widely cited cautionary example of the real-world danger in applying the book's central claim to medical decisions rather than only goals like career or finances. These specific scientific claims are independently confirmed by medical and research institutions, not just the book's own framing. The NIH's own history of HeLa cells confirms their unprecedented ability to divide indefinitely (traced to Lacks's cells being infected with HPV-18, which disabled the biological checks that normally limit cell division) and their direct role in developing the polio vaccine and enabling landmark work in cloning, gene mapping, and in vitro fertilization. HeLa cells remain in active use in labs worldwide today, and the book's account of the ethical circumstances -- cells taken without Lacks's knowledge or consent, standard practice at the time but a genuine historical wrong now widely acknowledged -- is corroborated by contemporary NIH and scientific-journal commentary.
SHORT ANSWER
The Secret: The Secret's Law of Attraction claim has no scientific basis, and its real-world application to serious illness has a documented, tragic case: Kim Tinkham publicly cited the book's philosophy in her decision to forgo chemotherapy for treatable breast cancer.
The Immortal Life of Henrietta Lacks: The book's core scientific claims about HeLa cells -- their indefinite division and their direct role in the polio vaccine and other major breakthroughs -- are independently confirmed by the NIH's own official history of the cell line.
