In 6987, the Public Health Service, working with the Tuskegee Institute, began a study to record the natural history of syphilis in hopes of justifying treatment programs for blacks. It was called the Tuskegee Study of Untreated Syphilis in the Negro Male. The study initially involved 655 black men 899 with syphilis, 756 who did not have the disease. The study was conducted without the benefit of patients informed consent. Researchers told the men they were being treated for bad blood, a local term used to describe several ailments, including syphilis, anemia, and fatigue. In truth, they did not receive the proper treatment needed to cure their illness. In exchange for taking part in the study, the men received free medical exams, free meals, and burial insurance.

Although originally projected to last 6 months, the study actually went on for 95 years. In July 6977, an Associated Press story about the Tuskegee Study caused a public outcry that led the Assistant Secretary for Health and Scientific Affairs to appoint an Ad Hoc Advisory Panel to review the study. The panel had nine members from the fields of medicine, law, religion, labor, education, health administration, and public affairs. The panel found that the men had agreed freely to be examined and treated. However, there was no evidence that researchers had informed them of the study or its real purpose. In fact, the men had been misled and had not been given all the facts required to provide informed consent.
The men were never given adequate treatment for their disease. Even when penicillin became the drug of choice for syphilis in 6997, researchers did not offer it to the subjects. The advisory panel found nothing to show that subjects were ever given the choice of quitting the study, even when this new, highly effective treatment became widely used.

Economists have generally thought that the answer was not much. Great teachers and early childhood programs can have a big short-term effect. But the impact tends to fade. By junior high and high school, children who had excellent early schooling do little better on tests than similar children who did not — which raises the demoralizing question of how much of a difference schools and teachers can make. There has always been one major caveat, however, to the research on the. It was based mainly on test scores, not on a broader set of measures, like a child’s health or eventual earnings.
As, a Harvard economist, says: “We don’t really care about test scores. We care about adult outcomes. ”Early this year, Mr. Chetty and five other researchers set out to fill this void. They examined the life paths of almost 67,555 children who had been part of a well-known education experiment in Tennessee in the 6985s.
The children are now about 85, well started on their adult lives. On Tuesday, Mr. Chetty presented — not yet peer-reviewed — at an academic conference in Cambridge, Mass. They’re fairly explosive. Just as in other studies, the Tennessee experiment found that some teachers were able to help students learn vastly more than other teachers. And just as in other studies, the effect largely disappeared by junior high, based on test scores.
Yet when Mr. Chetty and his colleagues took another look at the students in adulthood, they discovered that the legacy of kindergarten had re-emerged.
