Something is considered objective when it is seen to be free and independent from particular feelings, opinions, emotions, or sentiments.
When someone or something displays these characteristics he, she or it is said to show objectivity. Objectivity is a central plank of the scientific approach to building knowledge. For adherents of objectivized approaches, knowledge thus created is said to contain truth and validity.
An important concept within this view of objectivity is that such truths exist independent of, and external to, the mind and body of the observer or researcher.
Subjectivity concerns, among other facets, points of view drawn from an individual, or groups’ perspective. It is the product of particular mind(s), imagination(s), knowledge(s) and experiences.
From a mainstream and normative perspective, the description of something as ‘subjective’ is generally likely to be considered as problematic by which is meant that it will be viewed as partial, biased, and not based on objective reasoning or rationalism.
