Partiality means to be unfair, bias, to have inclination, to be in favour of one over the other. Partiality has been in the nature of man right from time.
Everybody has been partial in judgment at a point in time, human brain has been trained to judge people due to emotions, thereby making favors to those who are closer to them or who they intend getting favours in exchange.
Let me ask you a question.
Take for instance, you are the head of the human resource(HR) department of a company, during a mass interview for new employees, you came across a close relative who is not totally qualified for the job, what will you do?
Or take for instance, you are to commission some government project out due to your position as a politician, and you know of an old friend in the field, who will surely agree to do the job for a lesser price so that the remaining money can be shared between the two of you, will you give him the commission?. We can discuss that in the comment section.
DECENTRALISATION
Decentralisation is the transfer of control of an activity, or organization to several local offices or authorities rather than one single one.
Dictionary meaning
The process of decentralisation makes the lower level managers question their judgement and abilities. When given responsibility and decision- making freedom, they are challenged to develop solutions. In the long run, this does a world of good to their confidence and promotes self-reliance.

Partiality in decentralisation
Hive and some significant tribes has successfully kept to the standard of decentralisation in most of the aspects mentioned in the paragraph above, but what exactly is going on in the curation system, most people has made their sense of partiality dominant in their style of curation, taking a look at @onealfa/how-much-do-you-selfvote by 
The main and initial purpose of Hive and Steem that makes it different from Facebook and Twitter is the fact that a common person is able to create contents and get rewarded for their contents and engagement, but as time goes on, some set of people (whales) has communized the habit of curating their fellow whales with the aim of getting curations back from them, while leaving the newbie who are striving to contribute to the tribe and get rewards for themselves.
CAN THE ISSUE OF PARTIALITY BE SOLVED?
In my own opinion, I don't think particularly can be totally eradicated, but things can improve, and partiality can be made minimal.
Human will always be in favour of either their loved ones or their personal gain over a strangers, but considering the fact that a country, state, community or tribe should move forward, one has to let go of one's personal emotions or personal benefits. If these is in place, with time the country or community will be a better place for everyone and everyone will surely benefit from it. The reason why the world will continue to be a Place of violence is partiality.
For instance, the first question I asked earlier in this post, you eventually employs the stranger that has the full skill and qualifications. It will surely benefit the company more than when you employ the relative with little skill and less qualifications.
DISADVANTAGES OF PARTIALITY
It stops the community's growth
It decreases team spirit and breaks team apart
It brings jealousy and dissatisfaction
It affects motivation.
Where partiality is absent, equality and justice prevails. When there is equality, this means everybody gets similar rewards for similar efforts. This will boost the value of a community in relation to others who do not put equality as a priority.
Thank you for reading through, my optimum wish is that the world becomes a better place someday, and this can only be a reality when Partiality is been forsaken and equality becomes the oder of the day.
