Big Five personality traits (OCEAN)
The most widely and robustly examined model of human personality, identified through factor analysis across decades of research on diverse populations. Five broad traits are held to encapsulate most personality differences, commonly remembered by the acronym OCEAN:
| Trait | Low scorers | High scorers |
|---|---|---|
| Openness to experience | Practical, conventional | Creative, imaginative |
| Conscientiousness | Spontaneous, careless | Organized, self-directed |
| Extraversion | Aloof, quiet | Outgoing, enthusiastic |
| Agreeableness | Suspicious, hostile | Trusting, empathetic |
| Neuroticism | Emotionally stable | Prone to anger, anxiety |
Per The Gamer’s Brain (book) (Chapter 6), the model is useful precisely because it’s robust across long-term, large-population studies — but Hodent is explicit that it is not accurate at predicting individual behavior; it’s a description of trait clusters, not a forecasting tool. Notably, the book does not attach a founding academic citation to the OCEAN model itself when introducing it — it’s presented as established psychological consensus rather than a single study’s claim.
Extension to games: Yee’s gaming-motivation clusters
Hodent (Chapter 12) cites Nick Yee’s 2016 finding (“Gaming Motivations Align with Personality Traits,” a blog post analyzing survey data from over 140,000 gamers) that the five-factor model appears to align with gaming motivation clusters:
- Action-social (destruction, excitement, competition, community) correlates with extraversion
- Mastery-achievement (challenge, strategy, completion, power) correlates with conscientiousness
- Immersion-creativity (fantasy, story, design, discovery) correlates with openness
Neuroticism and agreeableness were not found to map to any gaming-motivation cluster. Hodent flags this research as recent and not yet fully reliable, but notes it as a promising path.
Extension to games: Bartle’s player types
Alongside Yee, Hodent cites Richard Bartle’s 1996 taxonomy of player types (“Hearts, Clubs, Diamonds, Spades: Players Who Suit MUDs”): achievers (motivated by mastery and accomplishment), explorers (motivated by discovery), socializers (motivated by social interaction), and killers (motivated by competition and destruction). She presents Bartle’s typology as a separate, earlier attempt at the same underlying problem the OCEAN-alignment research (Yee) is now tackling more empirically.
Hodent’s practical conclusion: no personality model currently predicts individual player behavior reliably enough to design around a single type, so the safer design approach is to offer a variety of activities, missions, and rewards that appeal across trait clusters rather than targeting one profile — unless a narrower audience is a deliberate choice.
