Study: Short Videos Harm Cognition
24 Nov
Summary
- Excessive short-form video use linked to poorer attention.
- Habituation to fast content damages focus on slower tasks.
- Short videos correlate with increased stress and anxiety.

New research indicates that prolonged engagement with short-form video content on social media platforms is detrimental to cognitive functions, including attention and inhibitory control. The study, analyzing data from nearly 100,000 participants, suggests that the constant influx of rapidly stimulating content may lead to desensitization, making users less capable of focusing on more demanding tasks like deep learning or reading.
This phenomenon, often referred to as 'brain rot,' is characterized by a perceived decline in mental acuity due to overconsumption of trivial online material. Beyond cognitive impacts, the study associates frequent use of short-form videos with negative mental health outcomes. Researchers noted a dopamine-driven reinforcement loop that can foster habitual usage and emotional reliance on digital interactions, potentially increasing stress and anxiety.
Furthermore, the reliance on passive digital engagement through short videos may displace real-world interactions, contributing to social isolation and reduced overall life satisfaction. Previous research, including studies on AI's impact on cognitive function and social media use in children, has also raised concerns about cognitive decline in the digital age.
