Exploring the Scientific Credibility of Personality Tests and Astrology

What Harry Potter house are you? What’s your mbti? What’s your zodiac? What kind of fruit are you? What are your big three? 

I’ve asked and been asked these questions time and time again. I’ve always enjoyed categorizing myself and compartmentalizing aspects of my personality to fit into aesthetic groups. I’m personally a Hufflepuff, an INFP, and a Taurus. I’ve never thought about whether or not there was any real science behind these types of classifications. Is there any scientific or data-driven backing for these? Why do we spend so much time thinking about what our MBTI is or what kind of personality type we have? 

Let’s first dive into the history and of some of these. 

History of MBTI or Myers-Briggs Type Indicator

Briggs and Myers, a mother-daughter team, aspired to delve into the intricacies of diverse personality types by integrating Carl Jung’s concepts into their own framework. Myers held the conviction that through their assessment, individuals could enhance their comprehension of one another’s personalities, fostering improved collaboration and minimizing conflicts.

What stands out prominently is that neither Briggs nor Myers possessed formal training in psychology. Briggs, with a keen interest in children’s psychology, aimed to develop a tool for early childhood education and specialization. Her daughter, Myers, adopted this perspective and envisioned using the indicator as a means to assist individuals in finding happiness.

History of Astrology

Prior to astrology, divination held sway, involving the interpretation of the influence exerted by stars and planets on earthly matters and human destinies. The roots of astrology can be traced back to Mesopotamia, traversing through India, Greece, China, Islamic culture, and Arabic learning.

According to Greek tradition, the heavens are delineated by the 12 constellations of the zodiac, each believed to possess a spiritual influence on human affairs. Astrology has permeated various cultures, and many contemporary individuals adhere to the notion that horoscopes wield control or significant influence over our lives.

Now, we confront a pivotal question: is there any scientific substantiation for these beliefs? Can they be deemed reliable in any capacity?

Fact or Fiction: MBTI

As previously noted, the foundation of MBTI is rooted in Carl Jung’s theoretical exploration of psychological types, focusing on different states of consciousness rather than distinctly defined personality types. 

For a personality assessment to be considered a meaningful measurement tool, it must exhibit both reliability and validity—qualities notably absent in MBTI. Many individuals experience inconsistent outcomes when taking the test multiple times, raising questions about the assessment’s significance. Clearly, the answer is in the negative.

Despite its lack of credibility, MBTI remains widely embraced, primarily due to the Barnum or Forer effect. This phenomenon reflects people’s tendency to readily accept vague and generic personality descriptions as personally insightful. While the scientific evidence supporting this personality test is limited, it may still be enjoyed for amusement purposes.

Fact or Fiction: Astrology

Starting with the foundation, astrology relies on celestial bodies such as the sun, moon, planets, and constellations. It utilizes the positions and movements of these heavenly bodies to formulate predictions and explanations for various aspects of human life, events, and personality traits.

Similar to the MBTI, astrology encounters comparable challenges, notably in the tendency to generate overly broad expectations, allowing interpretations that can apply to almost any outcome. Consequently, astrology lacks testability, and the available evidence fails to substantiate the validity of its concepts. In the scientific realm, ideas undergo modification based on compelling evidence, a principle not embraced by astrology, which remains unchanged despite contradictory evidence.

Furthermore, astrology faces criticism within the scientific community regarding the dissemination of research. Typically, published astrological articles lack the scrutiny of peer review, a fundamental practice in scientific inquiry. Additionally, there is an absence of documented instances where astrology has contributed to significant scientific discoveries.

Final Thoughts

In conclusion, while personality frameworks like MBTI and astrological concepts such as horoscopes and zodiacs have garnered widespread popularity and cultural significance, their scientific foundations remain highly debated and often contested. The lack of empirical evidence, inconsistent test-retest reliability, and the tendency for generalized statements to resonate with a broad audience raise skepticism about the validity of these systems from a scientific standpoint. While these frameworks may provide personal insights or entertainment for some, it’s essential to approach them with a critical mindset and acknowledge their limitations in terms of scientific rigor and empirical support. As our understanding of psychology and the universe continues to evolve, a cautious and discerning approach is advisable when considering the scientific legitimacy of such personality assessments and astrological beliefs.
