Personality trait

Dwarven personalities are determined by a set of traits. These traits are distinct from attributes.

Personality traits are shown in a dwarf's "thoughts and preferences" description page, which can be accessed by viewing that dwarf then p, z, Enter, or from the unit menu with view, Enter.

Each trait has a value from 0 to 100. The value triggers a report in "thoughts and preferences" depending on where it falls in these seven levels:

Traits marked with a "*" are capable of conflicting with the dwarf's personal values.

Value Range	Values in Range	Probability	Effect
91 - 100	10	0.4%	Highest
76 - 90	15	2%	Very High
61 - 75	15	8.5%	High
40 - 60	21	78%	Neutral
25 - 39	15	8.5%	Low
10 - 24	15	2%	Very Low
0 - 9	10	0.4%	Lowest

The 40-60 range does not cause a report.

Traits are also influenced by species via the use of the PERSONALITY creature token. For example, dwarves are slightly more straightforward than average with a median of 55 in that trait, whereas goblins aren't likely to help others out - their altruism median is a mere 25, and is capped at 50.

Traits also have an effect on which social skills are learned in social interaction, and determine whether certain actions may give a good or bad thought. Traits may have other, more subtle effects on creature behaviour, which are currently not entirely understood.

Trait value distribution

To clarify how trait values are assigned, 16,000 dwarves were examined. The normalized traits (those with a mean value of 50) provided 432,000 data points; the results are shown below.

Plot of trait distribution.

Traits
Value Range	Original	Averaged	Proposed	Cumulative
0 to 9	0.3863%	0.3822%	0.3875%	0.3875%
10 to 24	1.8995%	1.928%	1.925%	2.3125%
25 to 39	8.5086%	8.4666%	8.4625%	10.775%
40 to 60	78.4465%	78.4465%	78.45%	89.225%
61 to 75	8,4245%	8.4666%	8.4625%	97.6875%
76 to 90	1.9565%	1.928%	1.925%	99.6125%
91 to 100	0.378%	0.3822%	0.3875%	100%

Understanding the results

The results demonstrate a better-than 78% chance that a normalized trait's value will fall within the "Neutral" band (from 40 to 60). Further, the probability of an outlying value decreases as distance from the mean value (50) increases. The results are similar to a Normal distribution (aka "Bell curve"), however they do not fall off quite as quickly in the "tails". A "High" or "Low" trait value will be generated approximately 8.5% of the time. A "Very High" or "Very Low" value will appear less than 2% of the time. The probability of receiving a trait in the "Highest" (or "Lowest") band is less than 0.4%; the probability of a dwarf receiving multiple extreme values is infinitesimal.
