The sixteen primary factors
Cattell's work on personality established that a meaningful description of an individual requires more than five broad traits. The sixteen primary factors span a wider map: from how warm or reserved a person is in relationships, to how rule-conscious, dominant, abstract-thinking, or tension-prone they tend to be. This profile captures those sixteen dimensions using three public-domain IPIP items each (48 items total), providing a fast but broad personality overview.
This is a non-diagnostic personality profile describing general tendencies. Results are informational and should not be used for clinical, diagnostic, or high-stakes selection decisions.
