(Press-News.org) A new study of Instagram posts has uncovered strong statistical correlations suggesting that social media images may play a key role in shaping public opinion toward events, with notable social and political effects. Nafiseh Jabbari Tofighi of Istanbul Medipol University, Turkey, and Reda Alhajj of University of Calgary, Canada, Istanbul Medipol University, Turkey, and University of Southern Denmark, Denmark, present these findings in the open-access journal PLOS One on July 30, 2025.
Some prior studies have suggested that images and videos on social media can significantly impact users’ sentiments toward certain sociopolitical topics. However, other studies suggest that such impacts are limited because users typically only process information that aligns with what they already believe.
While both textual data and image-based data have previously been used for research on sociopolitical sentiment, few studies have combined these two data types. To help fill that gap, Tofighi and Alhajj investigated potential links between the sentiments suggested by static images in Instagram posts and the sentiments expressed by users who commented on the posts.
The researchers selected 100 Instagram posts, each with high user engagement and high relevance to one of four sociopolitical movements: Black Live Matter, Women’s March, climate change protests, and anti-war demonstrations. They manually categorized the sentiment of each image as either positive or negative, and they used deep machine learning methods to analyze comments and determine the percentage of comments expressing positive versus negative sentiment.
The analysis showed strong alignment between sentiment scores for the images and the sentiment of later comments, supporting the idea that social media images may significantly influence public sentiment on sociopolitical events.
Images related to anti-war demonstrations had the highest correlations between visual and commenter sentiments, perhaps because of the emotionally charged nature of such images. Images related to climate change protests had lower correlations, perhaps because the impact of such visuals relies on users being more informed about the context. Images related to the Black Lives Matter and Women’s March movements had moderate correlations, perhaps because of broad variations in type of image and user personal backgrounds.
The authors note the potential for misrepresentation in their analysis as AI-generated or synthetic images may exist in the dataset. They call for the development of technology that can detect such content and filter it out of datasets going forward. These findings help set the stage for future research in the field and could help inform activist strategies and efforts to combat misinformation.

The unusual head of a fish and the puzzle of its genes
2025-07-30
Almost all animals have symmetrical bodies: If we look at the left and right halves of our body, the limbs, eyes and ears are arranged evenly along the axis that runs through the centre of our body. This bilateral symmetry is almost universal in all animals and is only very rarely broken – with exceptions like the five-armed starfish or crab species that have one large and one small claw. One example of broken bilateral symmetry is the cichlid fish Perissodus microlepis, which is native to Lake Tanganyika in Africa. Its head and especially ...
How does metformin lower blood sugar?
2025-07-30
Although metformin has been the go-to medication to manage type 2 diabetes for more than 60 years, researchers still do not have a complete picture of how it works. Scientists at Baylor College of Medicine and international collaborators have discovered a previously unrecognized new player mediating clinically relevant effects of metformin: the brain. By uncovering a brain pathway involved in metformin’s anti-diabetic action, researchers have discovered new possibilities for treating diabetes more effectively and precisely. The ...
Increasing solar power could lead to significant cuts in CO2 emissions
2025-07-30
Embargoed for release: Wednesday, July 30, 2:00 PM ET
Key points:
Researchers estimated that a 15% increase in U.S. solar power generation could reduce CO2 emissions by 8.54 million metric tons annually, offering major climate benefits.
The benefits of added solar power varied widely by region. Areas like California, Florida, Texas, Mid-Atlantic, Midwest, and Southwest exhibited major reductions in emissions from solar increases, while other areas, such as Central, New England, and Tennessee, saw minimal impact.
Solar expansion in one region can reduce emissions in neighboring regions, highlighting the importance of ...
Black Death offers window into how childhood malnutrition affects adult health
2025-07-30
The Black Death arrived on the shores of England in May 1348 and, in less than two years, spread throughout the country, killing an estimated 2 million people. The death toll from the disease, which was caused by the bacterium Yersinia pestis, got so high that officials in London and other cities opened new cemeteries where hundreds of bodies were interred every day.
According to a new study, those who died around the time of the Black Death may help scientists answer a decidedly modern question: How can malnutrition early in life shape the health of humans far into adulthood?
The answer may be more ...
Clinical trial finds safe, effective treatment for children with severe post-Covid syndrome
2025-07-30
In a small trial, Mass General Brigham researchers found a drug designed to treat Celiac disease supported a more rapid return to normal activities for patients following COVID.
Multisystem inflammatory syndrome in children (MIS-C) is a rare but serious condition that can occur after a COVID-19 infection, presenting as high fevers, gastrointestinal symptoms, and life-threatening cardiac injury. A small, randomized clinical trial led by Mass General Brigham investigators found the oral drug larazotide—an experimental drug originally designed to treat Celiac disease—was both safe and effective in treating children with MIS-C. Their results ...
Researchers map where solar energy delivers the biggest climate payoff
2025-07-30
Increasing solar power generation in the United States by 15% could lead to an annual reduction of 8.54 million metric tons of carbon dioxide emissions, according to researchers at Rutgers, the Harvard T.H. Chan School of Public Health and Stony Brook University.
The study, published in Science Advances, found that the climate benefits of solar power differ markedly throughout U.S. regions, pinpointing where clean energy investments return the greatest climate dividends.
In 2023, 60% of U.S. electricity generation relied on fossil fuels, while 3.9% came from solar, according to the U.S. Energy Information ...
Carbon fiber boosts dry-processed battery performance
2025-07-30
Oak Ridge National Laboratory (ORNL) researchers have overcome a barrier to using a more affordable, dry process for manufacturing the lithium-ion batteries used in vehicles and electronic devices. The resulting batteries provide greater electricity flow and reduced risk of overheating.
Dry processing is a method for making electrode films that eliminates the need for wet organic solvents that require increased factory floor space, time, energy, waste disposal and startup expenses. However, dry-processed films tear easily. To address this issue, ORNL researchers incorporated long carbon fibers, then tested coin cell batteries made from ...
