Langcleg, I'm a great believer that you have to see stats from a variety of angles. That includes scientific research. Rephrasing of a question or concept in a slightly different manner and then comparing the two often reveals an underlying bias or issue that's been neglected previously.
If you want to get to the heart of an issue or problem you need to be able to see it in 'three dimensions' rather than in a 'flat kind' of way.
'Being nice' can often be used to emotionally blackmail. Being fair can equally be manipulative and be rather cold hearted.
If you understand that the value that's more important to a group is one or another, you can pull their strings to a certain extent.
Personally I believe you should explore from both angles as it helps to remove that political manipulation and allow people to consider the idea more critically and freely.
Both being fair and being nice are important to how we all see society in different ways. If one or the other is neglected you risk a backlash, and the exploitation of that lack of compassion / sense of injustice.
