Understanding Personality Tests
The web is flooded with various "personality" assessments claiming to reveal your nature. While many serve merely as entertainment, a few strive to categorize individuals into distinct "types" and offer advice based on these classifications. Unfortunately, the majority of these tests lack statistical credibility.
A credible personality test should fulfill three essential criteria:
- Foundation on Established Psychological Theories: It must be grounded in substantial research that outlines how personality develops and is structured. This research should align with reputable psychological theories that have undergone rigorous peer review.
- Strong Test-Retest Reliability: Personalities tend to remain stable over time. When individuals retake the same test, their results should be largely similar. If a test yields vastly different "personality types" on consecutive attempts, it likely lacks statistical validity.
- Predictive Validity: A useful personality test should provide insights into an individual's future behaviors or at least indicate tendencies in specific situations. For instance, extroverted individuals are generally more engaged in social contexts, leading us to predict that they would be more sociable than their introverted peers. However, when someone is labeled as a "Hufflepuff," what tangible predictions can we make about their actions? Most personality tests fall short when evaluated against these benchmarks.
Evaluating the Myers-Briggs Test
Consider the widely known Myers-Briggs assessment, which categorizes people into one of sixteen "types" based on a four-by-four grid of opposing concepts, resulting in a four-letter acronym. Despite its popularity, this test faces significant criticism for not meeting the aforementioned standards.
First, it is based on theories derived from Carl Jung's ideas. There is insufficient theoretical support for the distinctions between "Thinking" versus "Feeling" or "Sensing" versus "Intuiting." While these distinctions may sound intriguing, they lack statistical significance.
For instance, if we rate someone on a scale from 0 to 100 for introversion and extroversion, those scoring between 0-49 are deemed introverted, while those between 51-100 are classified as extroverted. This means that an individual scoring 49 is labeled "introverted," just like someone scoring 12. Are these two individuals statistically comparable? Certainly not! Their personalities may manifest differently in social scenarios, yet the test treats them similarly.
The Complexity of Personality
Personality is intricate and ever-evolving. Simplifying it for entertainment can be misleading. Many individuals enjoy being classified as it offers them a framework for behavior. For example, identifying as a Slytherin might guide someone on how to act in various situations. While this can be a beneficial psychological strategy, it does not encapsulate the true essence of personality.
A comprehensive Psychological and Cognitive Assessment can capture the multifaceted nature of personality, requiring several hours of evaluation by a licensed psychologist. These thorough assessments include multiple standardized tests that yield significant data for diagnostic interpretation, but they tend to be expensive and are primarily used in clinical settings.
The HEXACO Model: A Reliable Alternative
Instead of relying on theory-based personality tests, two models, the "Big-5" and "HEXACO," utilize a statistical approach called Factor Analysis. In this method, a broad sample of individuals answers numerous questions, which are then analyzed for correlations. This process reveals how certain responses cluster, enabling the identification of distinct personality types.
Of the two, I advocate for the HEXACO model:
- H - Humility/Honesty: Individuals scoring high in this category tend to avoid manipulating others for personal gain, resist breaking rules, and are disinterested in wealth or status. In contrast, those with low scores may flatter others for personal advantage and prioritize material gain.
- E - Emotionality: High scorers in this area experience fear and anxiety, seeking emotional support from others, while low scorers are generally less affected by stressors and exhibit emotional detachment.
- X - Extroversion: Individuals with high scores feel confident in social settings and enjoy interaction, while low scorers may feel awkward in social situations.
- A - Agreeableness: High scorers tend to be forgiving and cooperative, while low scorers may harbor grudges and be critical of others.
- C - Conscientiousness: Those scoring high are organized and disciplined, whereas low scorers may be impulsive and indifferent to order.
- O - Openness to Experience: High scorers appreciate art and new ideas, whereas those scoring low may lack curiosity and avoid creativity.
Why Choose HEXACO Over Big-5?
I find the data supporting HEXACO compelling. You can take the HEXACO personality test at HEXACO.org, which offers versions with 60 and 100 questions, and even options for feedback from others who know you.
The HEXACO model's Humility/Honesty dimension captures a facet of personality overlooked by the Big-5, reflecting a desire for cooperation and rule-following distinct from Agreeableness. The data collected through these tests contributes to ongoing research, expanding the understanding of personality. It's accessible in numerous languages and is supported by an extensive reference page filled with peer-reviewed articles.
For those seeking genuine insights into personality—data-driven and research-backed without any cost—consider HEXACO. If you have read this article and desire more detailed information about personality types, please share your thoughts in the comments!
