The Science and Psychology of Traitify

A Picture is Worth
A Thousand Words

The New Gold Standard in Personality Assessment

Traitify's patented assessments collect personality data using human interaction with images. We validate against the Big Five and Holland Interest models and candidates can complete our tests 30x faster than traditional assessments.

  • Built for the modern attention span

    Built for the modern attention span:
    90 second test = 96% completion rate. Test-takers answer quickly by simply responding to a series of images making a "me" / "not me" choice. Say goodbye to test fatigue.

  • Designed for everyone

    Designed for everyone:
    Images make us mobile friendly for those who don’t have access to large screen devices, more accessible to imperfect readers, and easier to translate. We are EEOC compliant and are available in over 10 languages and counting.

  • Backed by rigorous science

    Backed by rigorous science:
    We've run dozens of multi-month studies with 10,000s of participants so far. And we’ll do so continuously to ensure reliability and validity that stands up to the scrutiny of our scientific peers. Our science is well-documented. Contact us for more information.

Validity and Reliability

Models and Inventories

Models and Inventories

Traitify set out to investigate personality in the workplace and how it can be used to identify and develop talent. There is no better model for this than the Big Five. For employee interests, we build off Holland’s exceptionally well-studied occupational themes.

Repeatedly validated


Our assessments have been repeatedly validated against established Big Five and career interest inventories. Our construct validity for Big Five ranges from 0.52 to 0.75, comparable to other questionnaires. Predictive Validity is established on a proprietary basis upon request.

Accurate and reliable


Our assessments are internally consistent and stable over time. Multiple studies have been conducted and show good test-retest reliability. Our Big Five assessment test-retest scores range from 0.66 to 0.77 for example.

Manuals and other guides are available for more details.
