An individuals perspective is simply your point of view, that is, your attitude toward or way of regarding something or some situation.
Pespective can be objective or subjective depending on the underlying facts, or even a combination of objective and subjective inputs, in the case of a complex assessment.
Right or Wrong?
Perspective can drive conclusions and in extreme cases this can result in diametrically opposite analysis with both parties thoroughly convinced they are correct.
For example, during the US civil war that began in 1861, a persons perspective on slavery was largely driven by geography (North or South).
Southerners viewed slavery as an economic necessity that was morally and ethically acceptable. The residents of the Northern states did not hold this view and a serious and violent conflict resulted.
In this case, the perspective was based on the situation. The type of farming industry in the south (cotton plantations and such) thrived due to the climate. These type of crops were less viable in the climates of the Northern states so did not grow there.
Also the sales of these crops were low margin and relied heavily on manual labour. Without the relatively inexpensive labour achieved through the practice of slavery the industries profitability would be severly impacted.
This issue was not prevelant in the Northern states (industry leaning more toward manufacturing), and so their perspective of the moral question around one human enslaving another was totally different.
Conflict Resolution
Understanding the complexities of perspective, giving consideration to their role in creating a conflict and using this knowlege to achieve a peaceful resolution for all parties can be an effective tool in your facilitation tool kit.
