Why Profilia exists.

Who I am

I'm Adrien Albuquerque. Trained as a software developer, fascinated by psychology since my teens, I built Profilia because the personality tests available online were either locked behind paywalls (16personalities, Truity), or used as a pretext to harvest emails and resell ad attention. None of them respected both the rigor of the underlying psychological models AND the user's time.

Profilia is my antidote: 11 tests grounded in established models, free, no account, no marketing tracking. I've been maintaining it solo since March 2026.

Why exactly these tests

Each test covers a distinct dimension of personality, behavior, identity, rhythm, motivation, learning, attachment, and is grounded in a published, widely used scientific model. None are invented for decoration.

The end goal is the Personality DNA: by completing at least 2 tests, you get a meta-profile that cross-references the axes to reveal what no single test can. That's what sets Profilia apart from a quiz aggregator.

Methodology and sources

Every test is implemented from publicly available scientific literature. Here's the academic source for each:

• DISC : DISC model, William Marston, 1928. Four behavioral dimensions (Dominance, Influence, Steadiness, Compliance).
• Leadership Style : synthesis of Kurt Lewin (1939), Hersey-Blanchard (1969), and Daniel Goleman (2000).
• Love Languages : Gary Chapman's five love languages (1992).
• RIASEC : RIASEC model, John Holland, 1959. Six vocational types for career orientation.
• Four Temperaments : Hippocrates's classical temperaments (5th century BCE), re-articulated by Galen and Kant.
• Jung Archetypes : from Carl Jung's psychological archetypes (1921), formalized by Margaret Mark and Carol Pearson (2001).
• Chronotype : Dr. Michael Breus's four-chronotype model (Lion, Bear, Wolf, Dolphin), The Power of When (2016).
• Spirit Animal : synthesis of animal symbolism across several traditions (Native American, Celtic, Asian). The one cultural outlier in an otherwise clinical catalogue.
• Four Tendencies : Gretchen Rubin's model, The Four Tendencies (2017). Response to inner and outer expectations.
• VARK : Neil Fleming's VARK model (1987). Four learning styles (Visual, Auditory, Read/Write, Kinesthetic).
• Big Five : Big Five model (OCEAN), Lewis Goldberg, 1992. Five continuous factors, measured with the 50 public-domain IPIP items.

Privacy commitment

Profilia is deliberately the opposite of the dominant business model for quiz sites. Concretely:

• No account required to take a test, see your results, or share them. If you create an account, it's only to keep history across devices, toggleable.
• No marketing cookies, no ad pixels, no data resale. Internal tracking anonymizes via a daily-rotating salt (Plausible-style, GDPR-compliant under France's CNIL audience-measurement exemption of July 4th, 2025).
• Source code not yet public but could become so. If transparency matters to you, ask.
