 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: Trump supporters unfazed by reversal on self-funding

By JULIE BYKOWICZ and EMILY SWANSON

WESTFIELD, Ind. (AP) — Donald Trump’s voters adored him for mostly paying his own way in the first half of the presidential campaign. Yet those same people are shrugging their shoulders now that he’s raising money just like the rivals he once disparaged as the “puppets” of big donors.

A new Associated Press-GfK poll found that 63 percent of Trump supporters say they’re at least somewhat more likely to back a self-funded candidate, just as he once was. However, just 13 percent consider it a problem that Trump changed his mind — and nearly all those think it’s only a minor one.

How can people care so strongly about a candidate’s original stance and then not care at all when he changes his mind?

At a Trump rally this week near Indianapolis, some of his most ardent supporters explained their thinking. Many said it wouldn’t be fair for Trump, a billionaire businessman, to have to spend his own money against Hillary Clinton. The presumptive Democratic nominee and her allies aim to raise $1 billion for the general election.

“It was inspiring to see someone spend their own money rather than relying on lobbyists,” said 18-year-old Maxwell Nugent, who will be casting his first presidential vote for Trump this November. “It makes it more profound for him to be asking all the people who supported him to be giving money to the campaign now.”

Nugent, who wore a black T-shirt that reads: “Hillary’s Lies Matter,” said he likes that Trump “started from the bottom, with no donors.”

So far, Trump has put about $50 million of his own money into his campaign, mostly through personal loans which he says he will not seek to recoup. But he assembled a fundraising operation two months ago and has raised more than $51 million for his campaign and Republican Party allies.

Others who attended the Indiana rally said they have some concerns about Trump raising money — but also have faith that he won’t bend his policies to appease donors.

“A big thing with me is that since he is a billionaire, he doesn’t need to be bought,” said Diane Martinez, who lives in Westfield, Indiana, and leads a group called Save Our Veterans that supports Trump.

Trump has lamented the influence that super-donors such as Charles and David Koch and Sheldon Adelson hold over Republican politicians, naming those three specifically.

Yet he’s now developing a relationship with Adelson, a billionaire Las Vegas gaming executive, that could unleash streams of money to help him win the election. The Koch brothers have no plans to back Trump.

Americans have a negative view of the amount of money in politics. An AP-NORC poll conducted in November of 2015 found that 8 in 10 Americans, Republicans and Democrats alike, think campaign contributions influence the decisions that elected officials make.

Trump supporters are among those who see an issue with the way campaign funding works. In the AP-GfK poll, 51 percent of Trump supporters call the way presidential candidates raise money for their campaigns very or extremely important to them, similar to the 46 percent of all Americans who say that.

“We need absolute reform,” said Victor Wakley, another Save Our Veterans member at the Indiana rally for Trump. “I loved that he was paying his own way, and I do have some concerns now that he’s not.”

Democrat Bernie Sanders, who solicited only small donations online and held no traditional fundraisers, made campaign finance reform a pillar of his presidential campaign. Clinton also has promised to press for an end to unlimited money that flows into campaigns through super political action committees, although she is making full use of those groups in her 2016 bid.

Trump has called super PACs “corrupt” but offered no policy proposals about campaign finance. He’s also stopped talking about the corrosive effect of donor money since he began raising it.

In an AP interview this spring, Trump said he is raising money only to help the Republican Party, and he has repeatedly said it would be easier for him to just write a big check to his own campaign. He also stresses that his campaign fundraising is coming from small donors, the way Sanders’ fundraising was.

None of those statements is entirely true.

Trump’s fundraising deal with the party includes a provision that the first $2,700 of any donation go to his campaign. The rest of it — up to about $500,000 per donor — is divided among the national party and some state Republican groups.

Online solicitations accounted for less than half of the money Trump raised in late May and June, and it’s not clear how much of it was from small donors. Fundraising reports to federal regulators are due Wednesday night.

On Trump’s self-funding reversal, 16 percent of all Americans polled by AP-GfK considered it a major problem and 21 percent a minor problem.

Among Clinton supporters, 26 percent say they’re at least somewhat more likely to support a candidate who’s funding his or her own campaign, but more than half say they consider Trump’s reversal to be a problem, including 27 percent who say they think it’s a major problem.

The Trump supporters say it’s no surprise Democrats are trying to emphasize Trump’s switch from self-funding to traditional funding.

“There are a couple of ways to look at it,” said Jerry Loza, a Trump supporter at the Indiana rally. “You could say it’s hypocrisy. You could also say it’s a different game now.”

The AP-GfK Poll of 1,009 adults was conducted online July 7-11, using a sample drawn from GfK’s probability-based KnowledgePanel, which is designed to be representative of the U.S. population. The margin of sampling error for all respondents is plus or minus 3.3 percentage points.

Respondents were first selected randomly using telephone or mail survey methods and later interviewed online. People selected for KnowledgePanel who didn’t have access to the Internet were provided access for free.

AP-GfK Poll: Voters split over how to secure US from illegal immigration
By EMILY SWANSON and VIVIAN SALAMA

WASHINGTON (AP) — Most Americans reject Donald Trump’s proposal to build a wall along the U.S. border with Mexico and his support for deporting those in the country illegally. But they’re divided on the presumptive Republican nominee’s proposed temporary ban on the entry of Muslims from other countries, a new survey finds.

The poll shows Trump’s shifting rhetoric on that ban might win some Americans over.

When it comes to Trump’s proposal to build a wall along the Mexican border, about 6 in 10 Americans oppose the idea while 4 in 10 are for it, the new Associated Press-GfK poll indicated.

Similarly, 6 in 10 Americans favor providing a way for immigrants who are in the country illegally to become U.S. citizens, while about 4 in 10 are opposed.
Seventy-six percent of Democrats, along with 44 percent of Republicans, favor a path to citizenship for immigrants in the country illegally. Among Trump’s supporters, just 38 percent are in favor of a path to citizenship. Sixty-seven percent of Republicans and just 21 percent of Democrats favor a border wall. Three-quarters of Trump’s supporters favor that proposal.

Trump’s likely rival, Democrat Hillary Clinton, has cast his calls for the border wall and temporary foreign Muslims ban as dangerous.

Trump supporter Marile Womack, 79, of Debary, Florida, adamantly favors the border wall. No one else “had the guts to do it,” she said. But the daughter of Austrian immigrants isn’t opposed to immigration from any country so long as it’s done legally.

“I don’t favor banning immigrants, but I am for investigating them before they come,” she said.

In contrast, Mark Wecker, a car salesman from Redding, California, called a border wall stupid, because “it’s a lot of money and it’s not going to keep them out if they want to get in.”

Three-quarters of Latinos, two-thirds of African-Americans and more than half of whites favor providing a path to citizenship. Forty-eight percent of whites, 26 percent of blacks and just 16 percent of Latinos favor a border wall.

Daniella Gil, a stay-at-home-mom from Cornelius, Oregon, who is the daughter of Mexican immigrants, said, “We should be focusing on the violence coming from Syria as opposed to Hispanics jumping the border.”

She said she supports immigration from any country so long as it’s done legally.

Americans are slightly more likely to oppose than favor a temporary ban on Muslims who are not U.S. citizens from entering the United States, by a 52 percent to 45 percent margin that has been strikingly consistent in AP-GfK polls conducted this year.

Sixty-nine percent of Republicans say they favor the temporary ban on Muslim immigration, while 68 percent of Democrats are opposed. Half of whites and just a third of non-whites say they favor the ban. Seventy-six percent of Trump supporters are in favor.

On a trip to Scotland last month, Trump shifted his rhetoric, saying he would instead “want terrorists out” of the U.S., and to do so, he would limit people’s entry from “specific terrorist countries and we know who those terrorist countries are.”

The poll indicates that rhetorical shift could win support. Among those asked more broadly about a temporary ban on immigrants from areas of the world where there is a history of terrorism against the U.S. or its allies, 63 percent are in favor and 34 percent opposed. Ninety-four percent of Trump supporters say they favor this proposal, as do 45 percent of Clinton supporters.

“That’s a necessity for creating stability,” said Ryan Williams, 40, a health care provider from Jacksonville, North Carolina.

Most Americans — 53 percent — think the United States is currently letting in too many refugees from Syria, engulfed in civil war since 2011 and the Islamic State militant group’s de facto center. President Barack Obama has pledged to admit some 10,000 Syrian refugees this year.

Another 33 percent think the current level is about right, while just 11 percent want to let in more. About 4 in 10 think there’s a very or somewhat high risk of refugees committing acts of religious or political violence in the United States, 34 percent think the risk moderate, and 24 percent consider it very or somewhat low.

Seventy-six percent of Republicans think the U.S. should allow fewer refugees. Among Democrats, 43 percent think the current level is about right, 38 percent think the U.S. should allow fewer, and 18 percent want to allow more.

Said Gil, the stay-at-home mom from Oregon, “Some of those people are innocent kids.”
