Rumors have it

Study: Trying to correct political myths may only entrench them further

2015-05-04
(Press-News.org) Bad news, fans of rational political discourse: A study by an MIT researcher shows that attempts to debunk political rumors may only reinforce their strength.

"Rumors are sticky," says Adam Berinsky, a professor of political science at MIT, and author of a paper detailing the study. "Corrections are difficult, and in some cases can even make the problem worse."

More specifically, Berinsky found in an experiment concerning the Affordable Care Act (ACA) that rebuttals of political rumors about the supposed existence of "death panels" sometimes increased belief in the myth among the public.

"Pure repetition, we know from psychology, makes information more powerful," Berinsky says.

In the case of the "death panels," Berinsky's research indicates that the best way to counteract these rumors is to find a political figure who could credibly debunk the rumor based on their broader political stand -- a Republican senator, for instance.

As Berinsky sees it, it is harder for a democracy to function well in a public environment pervaded by political myths. The nonexistent "death panels" were alleged to have decision-making power over whether citizens received health care; in reality, as Berinsky points out, the ACA had provisions to pay doctors for counseling patients about their end-of-life options.

"It makes communication between politicians and citizens kind of difficult, if these people think politicians are trying to kill their grandmothers," Berinsky observes.

After treatment: More belief, more rejection

The paper containing the results, "Rumors, Truths, and Reality: A Study of Political Misinformation," will be published in the British Journal of Political Science.

Berinsky conducted the experiment with three separate waves of public-opinion surveys in 2010, encompassing nearly 2,000 voters. The surveys tested multiple methods of debunking rumors about the ACA on multiple categories of respondents.

Among "attentive" voters who responded to the survey, 57 percent initially rejected the rumors about "death panels." After seeing a nonpartisan correction of the myth, those figures changed slightly, to a 60 percent rejection rate. But a Republican-sourced correction raised that rate to 69 percent, while a Democratic-based correction only led to a 60 percent rejection rate.

In each scenario, the acceptance rate of the rumor went up, while only the Republican-based debunking markedly changed the rejection rate. Other slices of the survey group yielded similar patterns in which both acceptance and rejection rates rose, with Democratic-sourced debunking efforts being the least effective.

When Berinsky conducted follow-up surveys of voters weeks later, he found that about 43 percent of all respondents (not just "attentive" ones) rejected the rumor. A nonpartisan debunking of the rumor produced a 51 percent rejection rate, but a debunking stemming from Republican sources yielded a 58 percent rejection rate, while a Democratic correction led to 53 percent of people rejecting the rumor.

A reason for the results, Berinsky surmises, is apparently minimal belief, among contemporary voters, in the existence of neutral sources of information.

"No one perceives these [sources] as nonpartisan," he says.

Berinsky's experiment also produced new data about the attachment of the electorate to myths in general. He asked respondents whether they believed in any or all of seven different myths, six of which concerned politics -- such as the myth that President Barack Obama is a Muslim, or the rumor that vote fraud in Ohio swung the 2004 presidential election to then-President George W. Bush. Only 5 percent of the population believed four or more of the seven rumors, but on average, people believed 1.8 of the rumors.

As Berinsky sees it, that means belief in seemingly outlandish ideas is not the province of a relatively small portion of uninformed, conspiracy-minded voters.

"It's not that there are some people who believe a lot of crazy things," Berinsky says. "There are a lot of people who believe some crazy things."

Fact: Book in the works

Other scholars say the study is an important addition to the academic literature on political rumors and voter knowledge.

In that vein, this paper is part of a larger project Berinsky has undertaken about political rumors and public opinion; he is currently working on a book project on the topic as well, to be published by Princeton University Press.

"There's a lot more interest about this in political science and psychology than there was 10 years ago," Berinsky says. He believes practitioners -- politicians, strategists, consultants, and more -- seem increasingly attuned to the research that scholars are producing in this vein as well.

"There is a lot more interest in trying to find out how people think, rather than assuming you know how they think," Berinsky says.

Pollen and clouds: April flowers bring May showers?

2015-05-04
ANN ARBOR--The main job of pollen is to help seed the next generation of trees and plants, but a new study from the University of Michigan and Texas A&M shows that the grains might also seed clouds. The unexpected findings demonstrate that these wind-carried capsules of genetic material might have an effect on the planet's climate. And they highlight a new link between plants and the atmosphere. Pollen has been largely ignored by atmospheric scientists who study aerosols--particles suspended in the air that scatter light and heat and play a role in cloud formation. "The ...

Dulaglutide in type 2 diabetes: Hint of added benefit with short-acting insulin

2015-05-04
Since 2014 dulaglutide has been approved alone or in combination with other drugs for the treatment of adults with type 2 diabetes. The German Institute for Quality and Efficiency in Health Care (IQWiG) examined in a dossier assessment whether this new drug offers an added benefit over the appropriate comparator therapies. IQWiG found a hint of minor added benefit for the combination with short-acting insulin with or without metformin. In contrast, an added benefit of dulaglutide versus the respective appropriate comparator therapy is not proven for the combination with ...

Researchers hope to improve dental health by changing caregiver's behavior

2015-05-04
Studies have long associated low-income areas with poor oral health. But dental researchers at Case Western Reserve University and University of Washington sensed that other factors related to income may be at work -- in particular, education level. So they recently investigated how a parent or other caregiver's education level and dental habits affect children's dental health. With data from 423 low-income African-American kindergarteners and their caregivers from a CWRU dental school study in 2007, researchers tested the hypothesis that a caregiver's education ...

Study illustrates how chickenpox virus can cause a stroke in an HIV patient

2015-05-04
MAYWOOD, IL - Patients infected with human immunodeficiency virus (HIV) can, in rare cases, experience bleeding on the brain that causes a type of stroke called intracerebral hemorrhage. A Loyola University Medical Center case study demonstrates that a virus called varicella-zoster can cause inflammation of blood vessels in the brain. This inflammation, known as cerebral vasculitis, can cause both hemorrhagic and non-hemorrhagic strokes. The study by Daniel Vela Duarte MD, David Pasquale, MD, and senior author Murray Flaster, MD, PhD, was presented during a meeting of ...

New test predicts sudden cardiac death in hemodialysis patients

2015-05-04
Madrid, Spain - 3 May 2015: A new test has been developed to predict sudden cardiac death in hemodialysis patients in whom such forecasts were previously impossible. The novel method was presented at ICNC 12 by Dr Akiyoshi Hashimoto, a cardiologist at Sapporo Medical University in Japan. The test uses a combination of nuclear medicine, C-reactive protein and electrocardiogram (ECG). ICNC is organised by the Nuclear Cardiology and Cardiac CT section of the European Association of Cardiovascular Imaging (EACVI), a registered branch of the European Society of Cardiology ...

Study reveals how a Rab protein controls HIV-1 replication

Study reveals how a Rab protein controls HIV-1 replication
2015-05-04
HIV-1 replication requires the coordinated movement of the virus's components toward the plasma membrane of an immune cell, where the virions are assembled and ultimately released. A study in The Journal of Cell Biology reveals how a Rab protein that controls intracellular trafficking supports HIV-1 assembly by promoting high levels of an important membrane lipid. New HIV-1 particles assemble at specialized sites in the plasma membrane that are enriched in PIP2, a phospholipid component of the membrane that recruits a viral protein called Pr55Gag (Gag) that directs HIV-1 ...

Hot under the collar: The untold dangers firefighters face in the line of duty

2015-05-04
What do you think is the biggest cause of death for firefighters on duty? Well if your first thought was burns or smoke inhalation you'd be wrong! According to research published in the June edition of Vascular Medicine "since 1977, sudden cardiac death has accounted for the largest share of on-duty deaths among firefighters - surpassing burns, trauma, asphyxiation and smoke inhalation." Although the number of deaths amongst firefighters is declining, cardiac death still counts for 42% of deaths in on-duty firefighters over the past 5 years. This is an astonishingly ...

Disney Research algorithm combines videos from unstructured camera arrays into panoramas

2015-05-04
Even non-professionals may someday be able to create high-quality video panoramas using multiple cameras with the help of an algorithm developed by a team of Disney researchers. Their method smooths out the blurring, ghosting and other distortions that routinely occur when video feeds from unstructured camera arrays are combined to create a single panoramic video. The algorithm corrects for the apparent difference in position of an object caused by different camera angles - known as parallax - and image warping that occurs because of slight timing differences between ...

Rheumatoid arthritis patients at increased risk of surprise heart attack

2015-05-04
Madrid, Spain - 4 May 2015: Patients with rheumatoid arthritis are at increased risk of a surprise heart attack, according to new research presented today at ICNC 12 by Dr Adriana Puente, a cardiologist in the National Medical Centre "20 de Noviembre" ISSSTE in Mexico City, Mexico. Risk was increased even when patients had no symptoms and was independent of traditional cardiovascular risk factors such as smoking and diabetes. Dr Puente said: "Our study suggests that one quarter of patients with rheumatoid arthritis and no symptoms of heart disease could have a heart attack ...

Exposure to air pollution in the first year of life increases risk for allergies

2015-05-04
New research from the Canadian Healthy Infant Longitudinal Development (CHILD) study shows that exposure to outdoor air pollution during the first year of life increases the risk of developing allergies to food, mould, pets and pests. The study, published in the journal Environmental Health Perspectives, showed that the sensitivity to allergens was associated with exposure to traffic-related air pollution during infancy. "With the increasing rates of allergies amongst children in Canada and elsewhere, we were interested in determining if air pollution from traffic might ...
