Activities and Hobbies and COMPILER Personality Types

Activity fields offer a different view from declared interests: what people choose to list as pursuits. A mention still does not establish participation, frequency or skill.

Eight COMPILER dimensions define the type codes. The same weighted factor scores and fixed global cutoffs are applied to every category; only the recorded preference field changes.

112,546 profiles have usable data for this comparison. Type samples range from 18 to 2,162, with a median of 344.

246 of 256 types meet the 70-profile sample minimum. 188 have at least five qualifying distinctive entries; 7 have twenty.

These are historical, unadjusted associations, not individual predictions. A missing mention is not a dislike. Age, gender, geography and list length may contribute to differences.

Patterns with substantial differences

These examples require at least 25 mentions in a type of at least 300 profiles, in addition to the common screening rules. They are examples with larger cells, not a claim of independent replication.

Theatre and acting

: 10.5% list this entry, compared with 3.2% outside the type. That is 3.32 times the listing rate, a 7.4-percentage-point gap (32 of 304 profiles).

Gardening

: 4.1% list this entry, compared with 1.3% outside the type. That is 3.25 times the listing rate, a 2.8-percentage-point gap (39 of 949 profiles).

Crafts and needlework

: 4.9% list this entry, compared with 1.6% outside the type. That is 3.09 times the listing rate, a 3.3-percentage-point gap (58 of 1,194 profiles).

The predefined 58-category catalog is searched only in the Activities field here. Exclusions distinguish playing instruments from Guitar Hero, exercise from phrases such as running late, and outdoor surfing from web surfing. Some hobby topics overlap with questionnaire content.

Personality type

Reading the eight letters

COMPILER uses the original proposed pole names below. These are provisional shorthand for broader dimensions, not clean logical opposites, abilities, diagnoses or judgments of worth.

Position	Higher factor score	Lower factor score	Meaning
1	C: Caregiving	A: Autonomy	Prioritizing care for others and family or close relationships.
2	O: Openness	T: Traditionalism	Intellectual, imaginative and artistic exploration.
3	M: Materialism	F: Frugality	Placing importance on appearance, money and expensive consumption, not actual wealth.
4	P: Prudence	S: Spontaneity	Orderliness, caution and deliberate self-control.
5	I: Intimacy	G: Guardedness	Emotional openness, accepting help and interpersonal trust.
6	L: Leadership	Y: Yielding	Wanting to lead or control and being comfortable with confrontation, not leadership skill.
7	E: Equanimity	V: Volatility	Emotional calm and steadiness rather than a strong need for reassurance.
8	R: Religiosity	N: Nonreligiosity	Religious faith and conventional restraint.

In particular, Autonomy does not mean an inability to care; Frugality is broader shorthand here than thrift alone; Leadership includes control/confrontation preferences rather than demonstrated skill.

What the comparison can establish

The catalog contains 58 entries. Distinctive rankings require at least 70 usable profiles in a type, 200 mentions overall, 10 in the type, 50 outside it, and at least three in each deterministic half. Listing-rate lift must be at least 1.25, the absolute gap at least 0.25 percentage points, and the direction positive in both halves.

Lift compares the selected type with everyone outside it in the same usable category cohort. Lists can contain fewer than twenty entries. The split-half rule screens consistency; it is not external validation or a multiple-testing guarantee. Larger ratios based on ten or twelve mentions remain uncertain.

Each person counts at most once per matched entry, but can match several entries. Common whole-field dislike/negation phrases are conservatively screened out of preference fields. Education concentrations are not dislike-screened. The matching catalogs are not exhaustive and may miss languages, aliases or prose descriptions.

The factor model combines 35 original trait scores. Each of its eight global cutoffs splits 253,717 eligible historical profiles into 126,859 higher and 126,858 lower scores. Marginal balance does not guarantee equal-sized combinations. The source spans 2008–2011; it is not a representative sample of current tastes or the general population.
