Barnum Effect - Brief Personal Reflection


The Barnum Effect "a little something for everyone".

Psychometric tests consist of Barnum Effect, which imply generalization, and human are likely to fall into the trap. The classic example will be personality test. A set of personality-related items have been administered, and the subjects are likely to accept the result describing their personality.

As I recalled few years back, my participants are very pleased with the personality test. Most of them agree with the interpretation. How reliable and valid of the test? Personally, I believe it is just the trick of test.

We can never realize that explanation of our personality traits always lay in every domain. The only discussion is to discover which trait you are most prominent, and being told that each of us have all the traits which qualified as less prominent. Therefore, it is likely to be accepted.

Implication of psychometric tests is effective across context such as education setting, workforce or counselling sessions. Nonetheless, it is undeniable that they serve as basic guideline to further in depth understanding human traits. I admit that prior understanding of traits is essential to ease the process of forming contact with one another.

I believe that it is reliable yet validity is questionable. It is not content specific, yet it is domain general. Domain generality doesn't have specific object or mechanism to be focused on. It is just similar as learning. Learning is just a label, it doesn't content any information about what we learn, how we learn, what is the function of learning and etc.

Barnum effect is the newly term for me. I don't regard it as faulty or wrong, in fact it gives me hope, in provided I am not over indulged in it.

Psychology is just a Barnum effect, it gives justification for human thought, behavior and affect. It gives a free will for human to believe in what they believe. Psychology is an infinite variation, presents in every scent of life, which also makes psychology so attractive.

p/s: Barnum Effect is not only applied to personality test, it applies to horoscope, palm reading, tarot cards and so on.

Full stop is not a Stop

My study has come to the full stop. After the submission of my final year project, I thought I will be delighted, yet I wasn't. I was apathetic. No more motivation to complete it, I already forgotten my achievement goals, I have given up. During the phase of life, I felt Life is just ain't about perfection. Imperfection in life is the essence of our growth. In order to grow, old proverb saying "no pain, no gain", it indeed applies to everyone of us. Being through thick and thin, sweat and tears, I started to realise that adaptation to sudden change is incredibly important. For instance, we have a goal to get a First Class Honour in our degree program, but our result speaks no to us. Is it show that we are stupid? Nope, it only tells us that it is a piece of paper which might granted us to obtain better job, yet which class you get is not the guarantee to get a better job. The end of college life, is the start of _______ life. People will fill in the blank themselves....

How to train your dragon (Movie)

If you said it is a waste to watch animation or cartoon in cinema, I will reject your idea. Firstly, most of the animation strongly project good moral ethics or values for the reference of audiences especially children. During the childhood, children ought to differentiate the right and the wrong distinctively, neither grey area nor in between. Value always serves as a guideline for us to oblige, not a compulsory because decision is still lied in the hand of human. This movie secretly intruded my deepen heart. It talked about relationship, a bond between dragon and human. The main character, Hiccup chose to save the night fury (dragon) because he saw the fear from its eye. Even a human, we got attracted or closer with people who are similar to us because we feel we able to understand each other better compared to differences. The flow of movie discussed the process of rejection, acceptance, understand and devotion in a relationship. When we are just a stranger for each other, we are re...
