Notice a video titled "You won't believe what this actor said." You click. It is a 10 minute video with 2 minutes of content. That is the pattern. Create curiosity. Stretch the payoff. Repeat.
The tricks are simple. Numbered lists that never deliver ten items. Thumbnails with shocked faces that do not match the video. Headlines that contradict themselves to provoke confusion. "The ending will surprise you" means the ending is predictable.
These patterns survive because they exploit a reflex. The brain wants closure. An open loop itches. Clickbait opens loops it never closes. That tension feels like engagement to the platform algorithm. So the platforms reward it.
The content itself is secondary. The hook is the pattern. Once you see it, you stop falling for it. But most people do not stop to see it. They react. The pattern works on reaction, not reflection.
Ignore the headline. Read the first sentence. If it does not deliver, move on. Paul
