Decision Fatigue for Users in Online Streaming Platforms

OVERVIEW
Streaming platforms have a paradox at their core: more content, less satisfaction. Users open Netflix to relax and instead spend thirty minutes scrolling, abandoning the search or defaulting to a rerun. This project set out to understand why choice becomes a burden and what design can do about it. For my research I studied decision fatigue in movie and TV selection through a mixed-methods study of 15 people, then translated the findings into concrete design directions for context-aware recommendation systems.
THE PROBLEM
Recommendation engines are built on past behavior, but past behavior is a poor proxy for present need. Watch one heavy drama and the algorithm serves more heavy dramas even when you're in the mood for something else. The result is a system that feels impersonal precisely when personalization is the entire promise.
The research literature framed my hypothesis: more options produce more decision-making stress, and AI recommendations can lower satisfaction when they override user autonomy. I wanted to see how this played out in real selection behavior, not just self-report.
The research question: How do users experience decision fatigue when choosing what to watch, and how might personalized, context-aware recommendations reduce it?
METHODS
I ran two rounds with separate participant pools to triangulate behavior against stated preference.
Round 1 — Contextual observation (8 participants, ~15 min each): Participants demonstrated how they'd recommend a show to a friend, recorded and observed in person. I analyzed sessions with the AEIOU framework (Activities, Environments, Interactions, Objects, Users) and built sequence/flow models of the recommendation process.
Round 2 — Semi-structured interviews (7 participants, 20–30 min each): Conducted in person and over Zoom, focused on decision-making processes, experiences with recommendation systems, and streaming habits. Each transcript was descriptively coded in Atlas.ti, then reconciled into a shared codebook.
Participants spanned ages 19–62 across a range of occupations and tech fluency, screened for recent streaming use.
WHAT I DISCOVERED
Three themes appeared consistently across both observation and interview data.
1. Trusted sources beat the algorithm: Most participants consulted several sources — friends, critics (Letterboxd, IMDb, Rotten Tomatoes) — before committing to platform-native recommendations, which were treated with distrust. Features like “Trending Now” were widely ignored for being transparent marketing tools.
2. Abundance triggers avoidance: Faced with endless rows on the home screen, participants frequently abandoned the search, settled for something, or rewatched familiar content. The volume of choice didn't add value — it compounded the problem.
3. People decide by shortcut: Decision clustered around three heuristics: favorite actors, current mood/season, and seasonal relevance. These mental shortcuts were how users cut a vast catalog down to a selection — yet the platforms gave them almost no way to filter along these lines.

DESIGN IMPLICATIONS
The findings pointed to six directions for a less fatiguing experience:
- Context-aware recommendations driven by real-time inputs (mood, genre, actor) rather than viewing history alone.
- Balance familiarity and discovery: a lane for comfort rewatches alongside curated, approachable new content.
- Filtering that matches how people actually decide: sort by actor, season, release window, or emotional tone.
- Social proof built in: friend-based recommendations, collaborative lists, and links to the external reviews users already trust.
- Mood-based browsing: let users pick an emotional state and get recommendations tuned to it.
- Personalized “trending”: relevance scoped to a user’s social circle instead of platform-wide noise.
A through-line surfaced in the data: users defaulted to Netflix not for its catalog but for its familiarity. Reducing decision fatigue isn't only about better recommendations — it's about an interface comfortable enough to lower the cost of choosing at all.

Proposed features plotted by impact against development feasibility.
LIMITATIONS & NEXT STEPS
The small sample limits generalizability. Future work would broaden the participant pool, move from implications into a tested prototype, run cross-platform comparison, and probe the social features more deeply — which is the area participants responded to most strongly.
TAKEAWAY
The instinct in recommendation design is to add intelligence. My research suggested the opposite: the fix for choice overload is often less — fewer options surfaced at once, clearer reasons behind each suggestion, and controls that map to the shortcuts people already use to decide.
