Maths problems hardly treat me well. They expose in some confusing simplicity and refuse to be interpreted.
After calculus and linear algebra, we have mathematical statistics this semester. Statistics is even more pratically useful. In this science, hypothesis testing outstands. As for the real world, we have limited time, money and data, but hypothesis testing gives a non-mathematical mathematical way to prove the rightness of the human guess.
And the biggest guess about human should be that who am I.
Given this question, most people would find themselves lost in infinite thinking, about some huge things that they may have never thought before and will never in the future. Some psychologists try to make some progress on this issues. They invent tests about the characteristics of human beings. One of these inventions is the MBTI test.
MBTI, Myers-Briggs Type Indicator, among thousands of its counterparts is said to be the most popular and trusted. According to wikipedia.org,
"The types the MBTI tests for, known as dichotomies, are extraversion, introversion, sensing, intuition, thinking, feeling, judging and perceiving. Participants are given one of 16 four-letter acronyms, such as ESTJ or INFP, indicating what they prefer. The term best-fit types refers to the ethical code that facilitators are required to follow. It states that the person taking the test is always the best judge of what their preferences are, and the test itself should never be used to make this decision."
Well, you may have not yet taken this famous test, but my guess is that you must have some experiences in taking such things. How do you evaluate the accuracy of a type test? You might give such remarks like "Yes, that's exactly me!" or "Certainly not me." or " Partly true." Do you really want to test your type or more willingly test the test itself?
Even though we hardly know who we are, we are actually who we are being in the moment. No matter how things change and how they make difference on us, it is we ourselves who assume which type we belong to. It looks like that we are prejudged to be some ENTPs or ISFJs. (ENTP and ISFJ are two types indicated by MBTI test.) The prejustice we hold is the hypothesis lurking under everyone's skin and bones.
I have done 2 versions of MBTI test till now and they tell two different answers. Though I have suggested this test to some of my friends, I started to doubt it. It is not a maths problem, but I was incurably involved. Because I want more participants to test the test, through the hypothesis testing approach.
