Personality Profiling

Personality Profiling is an applied discipline that took shape at the intersection of forensics, forensic psychology, and HR during the twentieth and twenty-first centuries.

No single founder. It has no single founder:

• The forensic strand was formalised at the FBI in the 1970s–1980s (the Behavioral Science Unit programme, John Douglas, Robert Ressler)
• Behavioural analysis through micro-expressions was systematised by Paul Ekman (FACS, 1978)
• HR profiling grew out of business's need for structured personnel assessment

The unifying idea. All these strands share a single idea: personality leaves stable traces accessible to observation.

The Baseline — the Central Concept

The norm of a specific person. The baseline: the individual "norm" of behaviour of a specific person.

First the norm, then deviations. To read deviations, the norm must first be established.

Three Data Sources

The profiler collects data from three sources simultaneously:

• Formal information — documents, biography, test results
• Somatic signals — facial expressions, gestures, voice, physiological responses
• The subject's self-report — interviews, narratives

Two Mechanisms of Interpretation

• Comparison against normative samples → establishes the statistical norm
• Structural analysis → assigns behaviour to a typological cluster

A probabilistic forecast. Not a diagnosis or a destiny, but a probabilistic forecast for a specific task.

Where the Method Is in Demand

Wherever a decision about a person must be made quickly on the basis of limited data:

• In personnel selection
• During negotiations
• In the investigation of incidents

For a task, not as a description. This practical orientation is precisely what distinguishes profiling from academic typologies such as Big Five — those describe personality as such, while a profile is constructed for a task.

Substantial Limitations

Profile quality. Depends directly on the volume of data and the profiler's skill.

Micro-expressions are not a lie detector. Ekman himself stated this explicitly: they help, but do not replace evidence.

Ethical questions. Covert profiling raises serious ethical questions.

Place in Errarium

A unique niche. In the Errarium atlas, Personality Profiling (#64) occupies a unique niche: it is the only method that systematically works with somatic data (D2) in an empirical rather than symbolic register.

Analogs.

• By formal data type — Big Five (#3) and MBTI (#4)
• By attention to somatic signals — Palmistry (#7) and Physiognomy (#14), though those interpret the body symbolically rather than behaviourally

A radical difference from astrology. From astrology (#1) and Human Design (#13) profiling differs radically: in those, destiny is read in the symbols of birth; here, in observable behaviour in the present.
