Zeigarnik Effect

Netflix’s content discovery flow is a masterclass in behavioural psychology, engineered to keep users engaged with minimal friction. Each screen subtly leverages biases that drive rewatching, reduce abandonment, and personalise perceived relevance. From unfinished series triggering the Zeigarnik effect, to trending content tapping into social proof, the platform uses repetition, visual hierarchy, and cognitive shortcuts to maintain momentum. Yet while effective, this approach often narrows user exposure, reinforcing known patterns at the cost of fresh discovery.

The flow

sentiment_very_satisfied

What works

  • Unfinished shows with visible progress bars drive strong return behaviour (Zeigarnik and goal-gradient effects)
  • Repeated exposure to familiar titles builds fluency and preference (mere exposure effect)
  • Personalisation based on past actions increases perceived relevance (confirmation and commitment biases)
  • Trending and exclusive labels use social cues and scarcity to boost perceived importance
  • Downloads and notifications act as cognitive triggers that revive viewing intent
sentiment_sad

What doesn't work

  • Repetition of titles across sections can lead to content fatigue and decision friction
  • Visual dominance of banners and trending tiles creates anchoring and limits exploration
  • Broad or ambiguous categories can cause avoidance due to the ambiguity effect
  • Social proof and popularity-based sorting may suppress diverse or niche content
  • Lack of list organisation tools limits control over personal queues and viewing goals
