WASHINGTON — The American public and U.S. scientists are light-years apart on science issues. And 98 percent of surveyed scientists say it’s a problem that we don’t know what they’re talking about.

Scientists are far less worried about genetically modified food, pesticide use and nuclear power than is the general public, according to matching polls of both the general public and the country’s largest general science organization. Scientists were more certain that global warming is caused by man, evolution is real, overpopulation is a danger and mandatory vaccination against childhood diseases is needed.

In eight of 13 science-oriented issues, there was a 20-percentage-point or higher gap separating the opinions of the public and members of the American Association for the Advancement of Science, according to survey work by the Pew Research Center. The gaps didn’t correlate to any liberal-conservative split; the scientists at times take more traditionally conservative views and at times more liberal.

“These are big and notable gaps,” said Lee Rainie, director of Pew’s internet, science and technology research. He said they are “pretty powerful indicators of the public and the scientific community seeing the world differently.”

Ninety-eight percent of scientists say humans evolved over time, compared with 65 percent of the public. The gap wasn’t quite as large for vaccines, with 86 percent of the scientists favoring mandatory childhood shots while 68 percent of the public did.

Eighty-seven percent of scientists said global warming is mostly due to human activity, while only half of the public did.
