i think they are just measuring personality traits. on the model of big five personality traits.....me too confuse becoz i had 35 strongly disagree, 35 strongly agree, 15 disagree, 13 agree and two neutrals that were abt police....

five traits are..

Closed-Minded Open to New Experiences
Disorganized Conscientious
Introverted Extraverted
Disagreeable Agreeable
Calm / Relaxed Nervous / High-Strung

now considering the questions one must go for strongly agree and strongly disagree, because no one wants to be on negative side.
if someone say that its extremism then i don't know what should be the answers of questions like...

Tends to find fault with others

Does a thorough job

Is original, comes up with new ideas

Can be somewhat careless

..Is relaxed, handles stress well

..Is full of energy

Starts quarrels with others

.Can be tense

..Is a reliable worker

.Is generally trusting

...Tends to be lazy

...Can be cold and aloof

..Does things efficiently

Remains calm in tense situations

..Gets nervous easily

Is easily distracted

.Is politically liberal

its doesn't mean that i am right by marking so many st agree and at disagree but the situation demands lots of strongly agree or strongly disagree. if someone try to be in the middle by just marking on agree and disagree itsor neutral then it might be possible the result lies in the middle, it means he/she doesn't know abt their personality so how they can be able to do justice to others?
that is my point of view, may be i am totally wrong.

Your point of view is fine with the jobs of aggressive in nature such as in Armed Forces or in Law inforcement agencies.

The nature of jobs which requires passive in approach usually requires cool minded people with simple gestures like agree and disagree. May in certain situations one has to show strong opinions or may show neutrality.

My expereince and opinion.

my result probably like this..... as i go through the same questions

Extroversion |||||||||||||||||||| 90%
Orderliness |||||||||||||||||||| 90%
Emotional Stability |||||||||||||||||| 74%
Accommodation |||||||||||| 42%
Inquisitiveness |||||||||||||||||||| 82%

The Big Five is currently the most accepted personality model in the scientific community. The Big Five emerged from the work of multiple independent scientists/researchers starting in the 1950s who using different techniques obtained similar results. Those results were that there are five distinct personality traits/dimensions. Here are your results on each dimension:

Extroversion results were very high which suggests you are overly talkative, outgoing, sociable and interacting at the expense too often of developing your own individual interests and internally based identity.

Orderliness results were very high which suggests you are overly organized, neat, structured and restrained at the expense too often of flexibility, variety, spontaneity, and fun.

Emotional Stability results were high which suggests you are very relaxed, calm, secure, and optimistic.

Accommodation results were moderately low which suggests you are, at times, overly selfish, uncooperative, and difficult at the expense of the well being of others.

Inquisitiveness results were high which suggests you are very intellectual, curious, imaginative but possibly not very practical.

I do not want to explore the details of the records discussed above right at this hour but one must not be too much social or talkative as it implies absolutely BAD for one type of job "i.e. passive in nature" but on the other hand GOOD for the other type of job "i.e. aggressive in nature."

So getting maximum percentages in the Psychological tests may not be a good thing for one type but may be good for other types of things.

Hope you it is good for you and the rest .

To some extent i am agree with your opinion because in aforementioned questions you have to be strongly agree/or disagree but not in every case as you can not be so strong in every situation considering your real life as in Real life one can be flexible in such actions because of various social/religious or other such impacts.

No one can be so perfect as you are describing yourself in questions by indicating Strongly Agree/disagree. so, i believe, one should be realistic and moderate and be very true to answer these questions. if we try to be over smart by Strongly Agree/Disagree, that will ultimately fail us optimistically.

u r rite, i mark that intentionally as i knew that what they are measuring....but i was unaware of the personality required for nab officers. even till today no one can say that what type of personality they want? i found about 90% candidates who had marked 30% neutral, and 60 agree and disagree, and 10% st agree and st disagree. everyone marked their options deliberately irrespective of the own thinking, knowing that neutral would be considered. so they gave us other 40 marks to match our personality with the given mcqs test. let c, what will happen. me hopping for the best.

All I know is that the answer of next eleventh question was same and sometimes even the questions were same. If I agree strongly with 10th question than I should strongly agree with 21st question. That phenomenon, I found while painting the computer readable answer sheet in DD psycho test. It would surely help the machines for evaluation of our psychology and integrity as well.
If above mentioned 5 personality traits are true than 20 of each should be agreed, strongly agreed, neutral and strongly disagreed.

yes, i found the same logic while attempting paper....

what about shortlisting for interviews????????????????

It will be interesting to see whether candidates with high score are dropped from interview as a result of psycho test, at which point it'll be clear as to what exactly are they looking for in a candidate.
