Disclaimer : The mentioned here is a personal opinion
1-
Despite
all the warnings before taking the test about telling your real behavior, what
you really do rather than what you think yourself are … I think it’s still
unavoidable to answer based upon the image you want for yourself rather than
the reality, yet it’s still useful because it will reflect some (or a lot of,
based on how much objective are you) the truth
2-
The test
is somehow showing the extreme result I think, for example, If you are INTJ,
the description of the personality given is that for 100%I, 100% N, 100% T and
100% J, for those who get low scores in any (50%), this will not be very
relevant, yet it still gives some insights about some properties of your
personality
3-
The test
is mood-dependent , for example, imagine someone doing this test after a big
problem happened for himself due to his poor planning on one issue, and imagine
the same person did it after a great success or promotion he got, I think the
answers to the questions (and hence the results) will be different, we are
still humans
4-
When you
take the tests, know more about this character represented in the result (I
said the character not you), then you behave in some situations with a
different behavior that was expected from this character (ex: got nervous when
you were expected –according to the assessment- to be calm), you might start
asking yourself, “why did I do that? I ought not to have done it –according to
my personality-?” … I don’t like this, I think this made us escape from one
kind of stereotyping to another which we created by our hands (this is yourself
and this is how you ought to behave), yes we need to follow up on our personal
behavior, but we shouldn’t judge our every single action against an expected
personality.
5-
The
questions are sometimes culture dependent, ex: asking about selecting liberal
candidates in elections, asking about some kind of art like music, sculpturing,
films and such, these things –and similar- might be seen in America –or the
west generally- with different perspective than in the middle-east, India or
china for example, I think openness trait should be examined with different set
of questions that are not culture-dependent
6-
Still
have concern about being restricted to measure only and specifically these 4 aspects of personality
and use it to estimate the whole personality. The four aspects are chosen by the
test creators for a certain reason and they admitted that there are other
(hundreds) of aspects that are present but can’t be included in the test practically,
however the 4 aspects are chosen according to a criteria that might not be
suitable for you or for the reason you are taking the test
7-
Still I
think it’s generally a good thing and helps knowing the strengths and weakness
points for oneself
8- Take the tests frequently (may be on yearly, bi-yearly or every 5 years) to check if any of your traits, characteristics or behaviors are evolving due to your interactions with others ... for me, I tried the big 5 traits test over 2 times over 5 years and found that my score in openness and conscientiousness increased significantly, and slightly for other traits ,most probably due to being involved in leadership roles and more interactions with others in addition to learning a lot in humanitarian fields
