How You’re Lowering Your Intelligence Every Day (Without Realising It)

Scrolling kills your attention. Your ability to hold focus on a single task — sustained attention — is partly shaped by what you repeatedly train yourself to do. Constant short-form scrolling repeatedly exposes you to new stimuli every few seconds. Over time, this can condition you to expect frequent novelty and make slower tasks feel less stimulating. Performance impact: Learning requires both working memory and sustained attention. When attention is constantly interrupted: * information may be encoded less effectively * working-memory resources are consumed by task switching * cognitive overload can happen sooner * weaker encoding can result in weaker later recall Short attention → weaker encoding Weaker encoding → poorer retention Dopamine and novelty: Scrolling provides frequent, sometimes unpredictable rewards and novelty. Variable rewards are powerful learning signals, which is one reason feeds can become difficult to stop checking. Avoid oversimplified claims such as permanently “lowering baseline dopamine sensitivity” unless strongly supported by evidence. How to improve it: Try periods of intentionally low stimulation. For example: * no phone * no short-form video * no constant music or background videos * allow your mind to wander * reduce stimulation before a difficult study session Before a deep-work session, consider spending 20–30 minutes doing something low stimulation such as walking, sitting quietly or preparing your workspace. The goal is not to “detox dopamine”. It is to reduce competing stimulation and make sustained attention easier.
