Personality and Minimalism: Why Some People Declutter and Others Collect

Minimalism became a cultural trend, but the underlying pull toward owning less — or the opposite pull toward keeping and collecting — predates the trend by a long way, and it lines up with personality more than with any particular aesthetic movement.

Conscientiousness: order as a functional need

High Conscientiousness predicts a strong preference for tidy, organized, low-clutter environments, not necessarily out of minimalist philosophy but because visual clutter genuinely interferes with this group's sense of control and focus. Lower Conscientiousness tends to accumulate more without much distress about it, since disorder doesn't carry the same cognitive cost.

Openness: minimalism as intentional philosophy vs. collecting as curiosity

High Openness shows an interesting split: some express it through deliberate, philosophy-driven minimalism (owning less to make room for experiences), while others express the same trait through active, curious collecting — books, records, objects tied to specific interests. Both are Openness-driven; they just point in different directions.

Neuroticism: attachment to objects as emotional security

Higher Neuroticism is associated with stronger emotional attachment to possessions as sources of security and continuity, which can make decluttering feel disproportionately distressing — not because of the object's practical value, but because of what letting go of it represents.

Extraversion: possessions as social objects

Extraverted relationships to belongings often center on things that facilitate shared experience — entertaining, hosting, visible display. Introverts more often value possessions for private, solitary use, with less concern about how a space reads to visitors.

There's no universally "healthier" amount of stuff

Minimalism isn't inherently better than a fuller, more collected way of living — both can be perfectly functional depending on what's actually driving them. The useful question isn't "how much should I own," but whether your current relationship to your belongings matches your actual values or is just inertia.
