====== Objectivity ======

**Definition:**  
*Objectivity* is the quality of being **unbiased, impartial, and based on observable facts**, rather than personal opinions, interpretations, or emotions.

===== Clinical Context =====
  * Objective findings are **measurable**, **replicable**, and **independent** of the observer.
  * Common examples:
    - Vital signs (e.g., blood pressure, heart rate)
    - Laboratory values (e.g., serum sodium 134 mmol/L)
    - Imaging results (e.g., CT showing midline shift)

===== Contrast with Subjectivity =====
^ Aspect ^ Objective ^ Subjective ^
| Basis | Facts, measurements | Personal perception |
| Example | Glasgow Coma Scale score = 8 | Patient reports "feeling dizzy" |
| Replicability | High | Low |
| Influence | Minimal emotional bias | High potential for bias |

===== Importance =====
  * Enhances **scientific rigor** and **clinical reliability**
  * Essential in:
    - Evidence-based medicine
    - Clinical trials
    - Prognostic scoring systems
    - Peer-reviewed publications
