(Press-News.org) COLUMBUS, Ohio – If you smugly believe you’re right in a disagreement with a friend or colleague, a new study suggests why you may actually be wrong.
Researchers found that people naturally assume they have all the information they need to make a decision or support their position, even when they do not.
The researchers called it the “illusion of information adequacy.”
“We found that, in general, people don’t stop to think whether there might be more information that would help them make a more informed decision,” said study co-author Angus Fletcher, a professor of English at The Ohio State University and member of the university’s Project Narrative.
“If you give people a few pieces of information that seems to line up, most will say ‘that sounds about right’ and go with that.”
The study was published today in the journal PLOS ONE. Fletcher completed the work with co-authors Hunter Gehlbach, an educational psychologist at Johns Hopkins University’s School of Education, and Carly Robinson, a senior researcher at Stanford University’s Graduate School of Education.
The study involved 1,261 Americans who participated online.
They were split into three groups who read an article about a fictional school that lacked adequate water. One group read an article that only gave reasons why the school should merge with another that had adequate water; a second group’s article only gave reasons for staying separate and hoping for other solutions; and the third control group read all the arguments for the schools merging and for staying separate.
The findings showed that the two groups who read only half the story – either just the pro-merging or the just the anti-merging arguments – still believed they had enough information to make a good decision, Fletcher said. Most of them said they would follow the recommendations in the article they read.
“Those with only half the information were actually more confident in their decision to merge or remain separate than those who had the complete story,” Fletcher said.
“They were quite sure that their decision was the right one, even though they didn’t have all the information.”
In addition, participants who had half the information said that they thought that most other people would make the same decision they did.
There was one piece of good news from the study, Fletcher said. Some of the participants who had read only one side of the story later read the arguments for the other side. And many of those participants were willing to change their minds about their decision, once they had all the facts.
That may not work all the time, especially on entrenched ideological issues, he said. In those cases, people may not trust new information, or they may try to reframe it to fit their preexisting views.
“But most interpersonal conflicts aren’t about ideology. They are just misunderstandings in the course of daily life,” Fletcher said.
These findings offer a complement to research on what is called naïve realism, the belief people have that their subjective understanding of a situation is the objective truth, Fletcher explained. Research on naïve realism often focuses on how people have different understandings of the same situation.
But the illusion of information adequacy shows that people may share the same understanding – if they both have enough information.
Fletcher, who studies how people are influenced by the power of stories, said people should make sure they have the full story about a situation before they take a stand or make a decision.
“As we found in this study, there’s this default mode in which people think they know all the relevant facts, even if they don’t,” he said.
“Your first move when you disagree with someone should be to think, ‘Is there something that I’m missing that would help me see their perspective and understand their position better?’ That’s the way to fight this illusion of information adequacy.”

New study shows how muscle energy production is impaired in type 2 diabetes
2024-10-09
A new study from Karolinska Institutet, published in Science Translational Medicine, shows that people with type 2 diabetes have lower levels of the protein that breaks down and converts creatine in the muscles. This leads to impaired function of the mitochondria, the 'powerhouses' of the cell.
Creatine is a natural compound in the body that is also found in foods such as meat and fish. It is also a popular supplement for improving exercise performance as it can make muscles work harder and longer before they become fatigued. Despite creatine's ...
Early human species benefited from food diversity in steep mountainous terrain
2024-10-09
A new study published in the journal Science Advances [1] by researchers at the IBS Center for Climate Physics (ICCP) at Pusan National University in South Korea shows that the patchwork of different ecosystems found in mountainous regions played a key role in the evolution of humans.
A notable feature of the archeological sites of early humans, members of the genus Homo known as hominins, is that they are often found in and near mountain regions. Using an extensive dataset of hominin fossils and artifacts, along with high-resolution landscape data and a 3-million-year-long simulation of Earth’s climate, the team of scientists from ICCP have provided a clearer picture of how ...
Researchers discover new insights into bacterial photosynthesis
2024-10-09
Researchers at the University of Liverpool and collaborators have discovered new understanding of bacterial photosynthesis.
Using cutting-edge techniques, investigators have unveiled intricate detailed images of the key photosynthetic protein complexes of purple bacteria. These images shed new light on how these microorganisms harness solar energy.
The study, published today, not only advances scientists’ understanding of bacterial photosynthesis but also has potential applications in the development of artificial photosynthetic systems for clean energy production.
Like plants, many ...

NYU Tandon School of Engineering study maps pedestrian crosswalks across entire cities, helping improve road safety and increase walkability
2024-10-09
As pedestrian fatalities in the United States reach a 40-year high, a novel approach to measuring crosswalk lengths across entire cities could provide urban planners with crucial data to improve safety interventions.
NYU Tandon School of Engineering researchers Marcel Moran and Debra F. Laefer published the first comprehensive, city-wide analysis of crosswalk distances in the Journal of the American Planning Association. Moran is an Urban Science Faculty Fellow at the Center for Urban Science + Progress (CUSP), and Laefer is a Professor of Civil and Urban Engineering and CUSP faculty member.
"In general, lots of important data related ...

Effects of environmental factors on Southeast Brazil’s coastal biodiversity surpass those of ecological processes
2024-10-09
Sea surface temperature, wave energy and freshwater discharge from rivers influence the abundance and size of the marine organisms that inhabit rocky shores along the coast of Southeast Brazil more than ecological processes such as competition and predation. In areas where the water is colder, such as the Lakes Region (Região dos Lagos) in Rio de Janeiro state, marine organisms are 25%-100% larger than in areas where it is warmer, such as the coast of São Paulo state.
These are the main conclusions of a study conducted by researchers affiliated with the Federal University of São Paulo (UNIFESP) in partnership with colleagues at the State University of Northern Rio de ...
