Many experts believe that lack of diversity in clinical trials is detrimental to achieving the best treatment for patients.
The most notable instance of medical racism occurred in 1932 when doctors from the United States Public Health Service embarked on thein which hundreds of Black men were used as subjects for experimentation and research. “I will tell you that, at least in the health field, we have tightened up that game, people don’t just say we’re going to take your organs, or we’re just going to use you as a guinea pig, those days have been so long gone,” Winn said. “Now that we are creating therapies and creating trials that would also benefit people of color, we still have this leftover mistrust.”
As is so common in today's 'progressive' 'research and media, there is no need to really try to find why statistics do not show perfect match to population distribution. It's always 'racism', 'sexism' or 'homophobia'.
