 WASHINGTON (AP) — Few Americans question that smoking causes cancer. But they express bigger doubts as concepts that scientists consider to be truths get further from our own experiences and the present time, an Associated Press-GfK poll found.

 Americans have more skepticism than confidence in global warming, the age of the Earth and evolution and have the most trouble believing a Big Bang created the universe 13.8 billion years ago.

 Rather than quizzing scientific knowledge, the survey asked people to rate their confidence in several statements about science and medicine.

On some, there’s broad acceptance. Just 4 percent doubt that smoking causes cancer, 6 percent question whether mental illness is a medical condition that affects the brain and 8 percent are skeptical there’s a genetic code inside our cells. More — 15 percent — have doubts about the safety and efficacy of childhood vaccines.

About 4 in 10 say they are not too confident or outright disbelieve that the earth is warming, mostly a result of man-made heat-trapping gases, that the Earth is 4.5 billion years old or that life on Earth evolved through a process of natural selection, though most were at least somewhat confident in each of those concepts. But a narrow majority — 51 percent — questions the Big Bang theory.

Those results depress and upset some of America’s top scientists, including several Nobel Prize winners, who vouched for the science in the statements tested, calling them settled scientific facts.

“Science ignorance is pervasive in our society, and these attitudes are reinforced when some of our leaders are openly antagonistic to established facts,” said 2013 Nobel Prize in medicine winner Randy Schekman of the University of California, Berkeley.

The poll highlights “the iron triangle of science, religion and politics,” said Anthony Leiserowitz, director of the Yale Project on Climate Change Communication.

And scientists know they’ve got the shakiest leg in the triangle.

To the public “most often values and beliefs trump science” when they conflict, said Alan Leshner, chief executive of the world’s largest scientific society, the American Association for the Advancement of Science.

Political values were closely tied to views on science in the poll, with Democrats more apt than Republicans to express confidence in evolution, the Big Bang, the age of the Earth and climate change.

Religious values are similarly important.

Confidence in evolution, the Big Bang, the age of the Earth and climate change decline sharply as faith in a supreme being rises, according to the poll. Likewise, those who regularly attend religious services or are evangelical Christians express much greater doubts about scientific concepts they may see as contradictory to their faith.

“When you are putting up facts against faith, facts can’t argue against faith,” said 2012 Nobel Prize winning biochemistry professor Robert Lefkowitz of Duke University. “It makes sense now that science would have made no headway because faith is untestable.”

But evolution, the age of the Earth and the Big Bang are all compatible with God, except to Bible literalists, said Francisco Ayala, a former priest and professor of biology, philosophy and logic at the University of California, Irvine. And Darrel Falk, a biology professor at Point Loma Nazarene University and an evangelical Christian, agreed, adding: “The story of the cosmos and the Big Bang of creation is not inconsistent with the message of Genesis 1, and there is much profound biblical scholarship to demonstrate this.”

Beyond religious belief, views on science may be tied to what we see with our own eyes. The closer an issue is to our bodies and the less complicated, the easier it is for people to believe, said John Staudenmaier, a Jesuit priest and historian of technology at the University of Detroit Mercy.

Marsha Brooks, a 59-year-old nanny who lives in Washington, D.C., said she’s certain smoking causes cancer because she saw her mother, aunts and uncles, all smokers, die of cancer. But when it comes to the universe beginning with a Big Bang or the Earth being about 4.5 billion years old, she has doubts. She explained: “It could be a lack of knowledge. It seems so far” away.

Jorge Delarosa, a 39-year-old architect from Bridgewater, N.J., pointed to a warm 2012 without a winter and said, “I feel the change. There must be a reason.” But when it came to Earth’s beginnings 4.5 billion years ago, he has doubts simply because “I wasn’t there.”

Experience and faith aren’t the only things affecting people’s views on science. Duke University’s Lefkowitz sees “the force of concerted campaigns to discredit scientific fact” as a more striking factor, citing significant interest groups — political, business and religious — campaigning against scientific truths on vaccines, climate change and evolution.

Yale’s Leiserowitz agreed but noted sometimes science wins out even against well-financed and loud opposition, as with smoking.

Widespread belief that smoking causes cancer “has come about because of very public, very focused public health campaigns,” AAAS’s Leshner said. A former acting director of the National Institute of Mental Health, Leshner said he was encouraged by the public’s acceptance that mental illness is a brain disease, something few believed 25 years ago, before just such a campaign.

That gives Leiserowitz hope for a greater public acceptance of climate change, but he fears it may be too late to do anything about it.

The AP-GfK Poll was conducted March 20-24, 2014, using KnowledgePanel, GfK’s probability-based online panel designed to be representative of the U.S. population. It involved online interviews with 1,012 adults and has a margin of sampling error of plus or minus 3.4 percentage points for all respondents.

Respondents were first selected randomly using phone or mail survey methods and were later interviewed online. People selected for KnowledgePanel who didn’t otherwise have access to the Internet were provided with the ability to access the Internet at no cost to them.

AP-GfK Poll: Economy, other issues overshadow abortion

DENVER (AP) — As a season of campaigning enters its final, intense weekend, a new Associated Press-GfK poll illustrates the challenge ahead for candidates and their allies trying to rally voters around traditional wedge issues such as abortion and gay marriage. This fall, voters just have other matters on their minds.

Social issues are eclipsed by concerns about the economy, health care, the Islamic State group and Ebola, the poll finds. And hovering over each of these individual issues is a broad dissatisfaction with President Barack Obama and Republican leaders in Congress.

Only 32 percent of likely voters called gay marriage an important issue, compared with 91 percent ranking the economy important, 78 percent with similar concerns about health care and 74 percent naming Ebola important. The issue that some Democrats have emphasized most of all — abortion rights — also has been a relatively low priority, with only 43 percent of likely voters in a September poll ranking it important.

Yet women’s health and reproductive rights have been at the center of campaigns for U.S. Senate in Alaska, Iowa, North Carolina and especially Colorado. There, half of the ads aired by Democratic Sen. Mark Udall and those backing his re-election have criticized his GOP opponent, Rep. Cory Gardner, on women’s health issues. They include a contention the 40-year-old congressman from eastern Colorado wants to ban some forms of birth control.

“Democrats this year clearly think that all that you need is that silver bullet of social issues,” said Katy Atkinson, a GOP political official in Denver. “It’s not. You need more.”

Gardner may have been able to parry the offensive by proposing that birth control pills be sold over-the-counter, without a prescription. After he began airing an ad on his proposal last month — as security concerns rose amid U.S. military action against the Islamic State group in the Middle East and the West Africa outbreak of the Ebola virus — Gardner moved ahead in public polls.

Gardner isn’t the only Republican to propose the sale of birth control over-the-counter. So, too, have Republicans running for Senate in North Carolina, Virginia and Minnesota.

The issue of access to birth control has also found its way into the Senate race in Iowa, where Democratic Rep. Bruce Braley has hammered his Republican opponent, state Sen. Joni Ernst, for her support of bestowing personhood status on a fetus. He says that would outlaw abortion, in-vitro fertilization and most kinds of contraception; she says she supports access to birth control and abortion in some circumstances.

Some voters have scoffed at the emphasis.

“They do a lot of yapping about how contraceptives have to do a lot with women’s health, which is a load of crap,” said Donald Johnson, 82, a staunch Republican in Clinton, Iowa. “If they want contraception, they can go and get it. It doesn’t cost that much. There’s no reason the government should be paying for it.”

On both abortion and same-sex marriage, recent AP-GfK polling has found likely voters more apt to trust Democrats than Republicans. But on issues that have captured more of voters’ attention this midterm season, such as the economy and protecting the country, Republicans have the advantage.

Republicans have emphasized terrorism and Ebola threats in the campaign’s closing days, though the poll suggests Ebola inspires less of a partisan preference than other issues.

Cindy Nath, a 59-year-old high school teacher in Colorado Springs, is most worried about economic inequality but also has concerns about reproductive freedom. A Democrat, she’s already cast an early ballot for Udall. But the issues her students discuss are very different — the Islamic State group and Ebola. “That’s what they’re talking about,” she said. “ISIS comes up every day.”

Women’s votes have shifted sharply between presidential years and midterm elections in recent contests, according to exit polling conducted for the AP and ABC, CBS, CNN, Fox and NBC. In 2012, women broke for Obama by an 11-point margin, while in 2010, when few candidates raised social issues as a major campaign theme, they split evenly between Democratic and Republican House candidates.

Atkinson noted that social issues usually poll low in priority but can be effective in defining candidates as too extreme. That’s how Democrats have won recently in Colorado. Although polling shows Udall slightly behind, his campaign believes he can win with a superior get-out-the-vote operation and by continuing to use women’s health issues to motivate key voting groups. Democrats are particularly targeting single women, whose participation dips in midterm elections.

The model is Sen. Michael Bennet’s 2010 come-from-behind win, where he similarly focused on women’s health. Still, a gender gap cuts both ways. Several recent polls in Colorado have shown Gardner’s advantage among men outpaces Udall’s among women.

But Jill Hanauer, a Denver-based Democratic strategist, said people should not mistake a temporary issue advantage for something permanent.

“Republicans have immediate issues to run on and Democrats have much broader, long-term ones like climate change and reproductive rights,” Hanauer said. “This election is one point in time, not a long-term trend.”

The AP-GfK Poll was conducted Oct. 16-20, using KnowledgePanel, GfK’s probability-based panel designed to be representative of the U.S. population. It involved online interviews with 1,608 adults and has a margin of sampling error of plus or minus 2.8 percentage points for all respondents.

Respondents were first selected randomly using phone or mail survey methods and later interviewed online. People selected for KnowledgePanel who didn’t otherwise have access to the Internet were provided with the ability to access the Internet at no cost to them.

AP-GfK Poll: 2 of 3 Americans think the threat posed by Islamic State is very important

By DEB RIECHMANN and EMILY SWANSON, Associated Press

WASHINGTON (AP) — Sixty-five percent of Americans now say the threat from the Islamic State group is very or even extremely important, and nearly half think the U.S. military response in Iraq and Syria has not gone far enough, according to an Associated Press-GfK poll. Most want to see America’s partners step up their contribution to the fight,

Less than half, 43 percent, approve of the way President Barack Obama is handling the danger posed by the extremist militants.

Greg Franke, 24, of Columbia, South Carolina, was among the 55 percent of those who disapproved. Franke, a 24-year-old assistant editor at a research library, said he thought Obama was too hesitant in responding to the militants, who have employed brutal tactics to swiftly seize territory.

“I understand the need to be hesitant, but this was a group that was marching across parts of the Middle East, which is already unstable,” Franke said. “I think it warranted a swift and more decisive response.”

“I also think that his declaration that U.S. troops would not be involved was premature,” he said. “I don’t want U.S. troops involved. But I don’t think we need to close doors.”

A majority, 66 percent, favor the airstrikes the United States has been launching against the militants, yet 65 percent of those surveyed say Obama has not clearly explained America’s goal in fighting the Islamic State group. The president met with his national security team on Friday to discuss the Islamic State and talk via video teleconference with U.S. officials at the American Embassy in Baghdad and consulates in Irbil and Basra.

Here’s a look at the poll:

IS ENOUGH BEING DONE?

Forty-six percent said the U.S. military response has not gone far enough — up from 40 percent in September. Fifty-six percent said the military response from countries that have joined the U.S. in the fight against Islamic State militants has not gone far enough. The U.S. and partner countries, including Qatar, Saudi Arabia and the United Arab Emirates, have been bombing Islamic State targets since August.

“It shouldn’t just be us. It shouldn’t just be ‘Oh, the United States is policing.’ It should be everyone is there policing and everybody believes this is wrong and everyone — worldwide — is trying to stop this,” said Kathy Robinson, 24, a Sterling, Virginia, woman who works at an information technology company.

At the same time, she thinks the United States eventually will put troops on the ground in the region “just to make sure nothing starts back up — to keep the peace.”

Only 32 percent think Obama has done a good job in clearly stating U.S. policy against the IS group. More than six in 10 of them think it’s either not likely or only moderately likely that the U.S. and its partners will achieve their goal in fighting IS.

ARE AMERICANS FOLLOWING DEVELOPMENTS IN IRAQ, SYRIA?

While 47 percent of those surveyed said there’s a very or extremely high risk of another terror attack inside the United States, just a third said they have been keenly following the news about the U.S. military action against IS. An additional 38 percent said they were following the action somewhat closely, and 31 percent said they were keeping up not too closely or not closely at all.

___

DO PEOPLE SUPPORT THE AIRSTRIKES?

While Americans support the airstrike, when it comes to supporting the idea of deploying U.S. ground troops, respondents were more guarded.

Thirty-seven percent said they opposed putting American forces on the ground, 33 percent favored the idea and 28 percent said they were neither for nor against it.

Obama has said repeatedly that he has no plans to send ground troops to Iraq or Syria. However, 28 percent thought it was very or extremely likely that he would, and an additional 45 percent thought it was moderately likely. Just 24 percent said it was not likely.

Michael Rainwater, 64, of Sammanish, Washington, doesn’t particularly want to see U.S. troops sent in, but thinks they might be deployed at some point.

“I think all of these things tend to escalate,” he said. “You can’t keep pouring fuel on the fire and expect the fire to get smaller. So every time we bomb or send in armed drones, you are creating more terrorists.”

He does not think, though, that the Islamic State is in a position to mount a 9/11-style attack against the U.S.

Said Rainwater, a retired software company owner: “It is more of a criminal entity because basically what they are doing is kidnapping people for ransom, taking over oil refineries for the income.”
