In the survey, released today (July 26), researchers got people's opinions on three emerging medical technologies: gene editing to reduce a baby's risk of disease, brain chip implantations to make people smarter, and synthetic blood to improve athletic performance. These technologies are not available right now, but some researchers are moving toward making these advancements a reality one day, according to the survey.
The survey included a nationally representative sample of about 4,700 American adults. In addition, Pew held six small focus groups with a total of 47 people to discuss the technologies and their potential implications, and to learn more about people's opinions than could be gleaned with only the survey.
