Hello everybody, 

 Sorry I haven't posted in quite a while, I've been at a bit of a lull in terms of my research as I am waiting for some survey results to come in. However, I dug up some new research on another type of personality test: The Big Five. 

 The Big Five is a personality test that is considered to be more valid than MBTI, mainly because it assesses people using a range of traits, (2) rather than giving them four letters and placing them in a box. Many psychologists also believe that The Big Five may be more reliable because the traits it uses can actually characterize a personality. (1) 

 The Big Five traits are: 

  • Openness: This trait is determined based on somebody's creativity, sense of adventure, and willingness to try new things. It also included how much a person enjoys thinking about theoretical and abstract concepts. Someone with little openness would be closed off, not very adventurous, and not fond of change. (1) 
  • Conscientiousness: determined by how thoughtful and goal oriented somebody is. Similarly to the context of 'Judging' in MBTI, conscientiousness also explains how someone may prefer to be organized and scheduled, as well as getting important tasks done on time and paying attention to detail. On the opposite side of this rage, somebody could be impulsive, spontaneous, and a procrastinator. (1) 
  • Extraversion: As many of you may remember from MBTI, extraversion measures whether people are "energized" by being alone or being around others. The more you prefer to be around other people, the more extraverted you are. (1)
  • Agreeableness: Someone who is very agreeable would be trusting and sometimes affectionate. They would show a great deal of interest in others and have a strong sense of empathy. Contrarily, someone who is not as agreeable would show little interest in others and may be very competitive. (1) 
  • Neuroticism: This defines levels of sadness, moodiness, anxiety, and emotional instability. Someone who is very neurotic would be emotionally unstable, whereas someone who isn't would be relaxed and have little difficulty dealing with stress. (1)

How reliable is The Big Five test? 

The Big Five traits are “remarkably universal,” (1) and much more reliable than MBTI. “Psychologist David Buss has proposed that an evolutionary explanation for these five core personality traits, suggesting that these personality traits represent the most important qualities that shape our social landscape.” (1) 

“These traits are developed over time due to nature and nurture.” (1) 

The Big Five also represents a RANGE between two personality traits and where you land on a spectrum between them. (2) 

Scientists have created mathematical methods to evaluate The Big Five and judge it’s validity. “The objective of this study was to evaluate the psychometric properties of the [Big Five.]” (3) They conclude the Big Five Test “provides satisfactory and reliable data.”( 3) 

 The Big Five isn't perfect, but it does something that the MBTI test does not do; it looks at a range of personalities and different traits rather than just categorizing preferences. (5) 

Uses for The Big Five

 The primary purpose for The Big Five would be, in my opinion, self-reflection. Much like MBTI, however, The Big Five is used to evaluate job performance. (4) 

Taking the test myself

 I took these two tests (feel free to take them yourself and share your results with me!) and compared the results. Both tests concluded: 

  • I was very open-minded
  • I was extremely conscientious
  • I wasn't very extraverted 
  • I was pretty agreeable 
  • I was quite neurotic

 Personally, I agree with these results. I think they represent me fairly accurately. I think I would trust The Big Five test because they ask a variety of questions, I was completely honest, and it supports the theory of 'test retest reliability' which means when taking a personality test twice you should get the same results. As well, they measure the personality with a scale rather than a numerical score, but with that said, the second test did give me a percentage of each category. Which brings me to believe there are significant flaws with The Big Five, including human error, and the results of one test affecting the results of the following test.

 That's all I've got for now! Next time I will be analyzing my survey results, and following that I would like to create a 'mini-test' based on The Big Five, because my research has led me to believe it's more accurate than MBTI. If anybody has suggestions of how I could create this test, please let me know! 

Cheers!
