The basic level in personality-trait hierarchies: studies of trait use and accessibility in different contexts.

A person's behavior and experiences can be described at different levels of abstraction. For example, a person might be described as charitable, as generous, as kind, or as good. Is there a level in such a trait hierarchy that is particularly useful in personality descriptions? The present 4 studies show that there is indeed a general preference for a particular level; the size of this preference depends on the familiarity and likability of the target people, which included various others and the self. These findings suggest that in trait hierarchies, people prefer the highest level of abstraction that is still descriptive of behavior (e.g., kind) over more descriptive subordinate levels (e.g., charitable and generous) and over an even broader level devoid of descriptive meaning (e.g., good). This level is basic in that it represents the optimal resolution of the trade-off between bandwidth and fidelity that characterizes all hierarchies.
