Objectivity.

Objectivity is something that relates to something or someone independently of the opinion of any individual.

I order to make an objective assessment, it's necessary to consider the process based on real facts.

Objectivity results in the same outcome even if different people give the rating. Subjectivity results in the rating being based on the person's opinion.

Reflection is a physical process. It can be seen in a mirror or in other places.

At the moment of reflection the object appears reflected.

There are different types of reflections, for example, object or sound.
