Quick summary: A new study argues that decades of research into how people read across multiple sources has failed to reflect how online reading actually works, calling for approaches that account for algorithms, cultural background, and emotional responses. Experts warn that emotionally charged content activates stress responses in the brain, impairing critical thinking, while habitual scrolling trains the brain for speed over depth, with serious consequences for decision-making. The findings carry clear implications for education and public health, with practitioners urged to incorporate emotional awareness and digital literacy into how people are taught to navigate information online.
Most people today do not read a single article and move on. They scroll through feeds, follow links, watch videos, and absorb information from dozens of sources before forming an opinion. A new study published in Educational Psychologist argues that researchers studying how people make sense of multiple texts have not kept pace with this reality, and calls for a significant rethink of how online reading comprehension is studied.
The study, led by researchers at the University of Florida, Lehigh University, the University of Utah, and the University of Texas at Austin, focuses on what academics call multiple text comprehension, the process by which readers draw meaning from more than one source at a time. For decades, studies in this area have placed participants in controlled laboratory settings and handed them a small selection of texts. The authors argue this approach misses much of what actually happens when people read online.
One of the central concerns raised is the role of algorithms. When someone searches for information on Google or scrolls through social media, the content they see is not neutral. Platforms are designed to keep users engaged, which means content that provokes emotion, whether outrage, excitement, or anxiety, tends to spread further and faster than measured, accurate reporting. Angela Williams, psychotherapist and leadership advisor, points to what this does to the brain. “Being exposed to material that elicits fear, outrage, scarcity, or urgency can activate our amygdala, switching on our fight or flight response. This emotional activation and distress impedes our ability to think critically.”
The researchers also highlight the importance of culture in shaping how people interpret what they read. Cultural background influences which sources a person trusts, how they approach a task, and what they already believe before they read a single word. Dr Maya Reynolds, psychiatrist and behavioural health spokesperson at Choice Point Health, notes that this dynamic is reinforced at an individual level. “Cultural background and prior belief systems further shape an individual’s overall interpretation. People are more likely to believe and process information that resonates with their personal identities and backgrounds.”
Emotions and affect receive particular attention in the study. The authors draw a distinction between the narrow understanding of emotion used in most comprehension research, which tends to focus on factors like interest and motivation, and a broader conception drawn from affect studies. In this wider view, readers are often driven by pre-conscious responses to stimulation, impulses that influence which texts they select and how they interpret them, before any deliberate reasoning takes place. Williams adds that habitual scrolling compounds the problem. “Our brains are trained for speed, not depth, while we are scrolling, and we don’t have enough time to reflect and integrate information. These skills are key for critical decision-making in the future.”
The rise of artificial intelligence adds further complexity. Large language models increasingly summarise information before users ever reach the original source. The authors warn that this reduces exposure to the kind of productive contradiction across texts that helps people build genuine knowledge and critical thinking skills. When summaries smooth over disagreements, readers lose the opportunity to reason across competing viewpoints.
The study does not dismiss existing research but argues it needs to expand into messier, more authentic territory. Recommended approaches include studying readers in real digital environments, using text sets that reflect cultural diversity, and measuring emotional responses alongside cognitive ones. Reynolds argues that the implications extend beyond academia. “Educators and practitioners should take digital literacy beyond a basic teaching source. It should include proper emotional awareness, so that people realise how feelings impact overall judgement and cognitive abilities.”
