subjective

sifat adjective

1. Formed, as in opinions, based upon a person's feelings or intuition, not upon observation or reasoning; coming more from within the observer than from observations of the external environment.
2. Pertaining to subjects as opposed to objects (A subject is one who perceives or is aware; an object is the thing perceived or the thing that the subject is aware of.)
3. Resulting from or pertaining to personal mindsets or experience, arising from perceptive mental conditions within the brain and not necessarily or directly from external stimuli.
4. Lacking in reality or substance.
