While in deep depression and drawn to the occult, she attempted to mentally duplicate 290 drawings created by her brother. Sinclair reported surprising success rates, though the experiments lacked scientific controls. The work attracted both praise—including a preface by Albert Einstein—and sharp criticism from skeptics who questioned the methodology and results. (This is an automatically generated summary.)
