Americans are careful to support gene editing technology to boost infant intelligence.

A majority of Americans support the use of gene-editing technology to treat infants with severe genetic diseases or avoid similar risks, but say it is "too much" to use it to improve the intelligence of future generations, according to a survey released Tuesday by the Pew Research Center.
but only 19 percent thought it was appropriate to change genes to make babies smarter, and about two-thirds of the participants opposed gene-editing tests on human embryos.
survey also showed that about 54 percent of people believe that gene editing technology can lead to "an unmanageable bad outcome", that is, "while in some cases, the use is reasonable, some aspects are morally unacceptable".
the study also found that men were more receptive to using gene editing techniques to alter the genetic composition of infants than women, while those with higher levels of scientific knowledge were more positive about them.
