Have you ever planned to check TikTok for five minutes, only to find an hour has passed? This is a common experience for many teenagers in Vietnam and around the world. It’s not just a lack of self-control; it’s by design. Popular applications like Facebook and TikTok are engineered to keep you engaged for as long as possible, which helps explain the high app usage times seen in market research.

One of the most effective techniques is the 'infinite scroll.' This feature creates a never-ending stream of content, so there's always something new to see. The design is a deliberate choice to remove natural stopping points, like turning a page in a book or reaching the end of a newspaper article. Without these cues, your brain doesn't get a clear signal to stop, making it easy to keep scrolling.

Another powerful tool is the 'pull-to-refresh' function. When you pull down the screen, you don't know what new content will appear. This action is similar to pulling the lever on a slot machine. The reward is unpredictable, which makes the experience exciting and keeps you coming back for more. This mechanism is so effective because it gives our brains a small hit of dopamine, a chemical linked to pleasure.

Being aware of these psychological tricks is the first step to developing healthier digital habits. It’s not about completely avoiding these apps, but understanding how they work. By recognizing the design features that aim to capture your attention, you can make more conscious decisions about how you spend your time online and regain control.
