Imparcial vs. objetivo vs. insesgado
While the Spanish words imparcial, objetivo, and insesgado all relate to fairness and truth, they are used in different contexts. Imparcial focuses on neutrality between people or sides, objetivo focuses on facts over feelings, and insesgado is a more technical term regarding the absence of statistical or systematic distortion.
Imparcial
B2The word imparcial is used when a person or entity refuses to take sides in a dispute or conflict. It implies justice, fairness, and a lack of favoritism toward any specific party involved.

(A judge must be completely impartial when listening to the witnesses.)

(We need an impartial mediator to resolve this labor dispute.)

(As a mother, I try to be impartial when my children argue.)

(The referee was criticized for not being impartial during the match.)
Objetivo
B1The word objetivo describes a perspective based on observable facts, reality, and logic rather than personal feelings, opinions, or emotions. It is the opposite of being subjective.

(The medical report offers an objective analysis of the patient's health.)

(From an objective point of view, the project is too expensive.)
Insesgado
C2The word insesgado is a more formal or technical term used primarily in statistics, research, and data science. It means that a sample, algorithm, or estimator is free from systematic error or sesgo (bias/slant) and accurately represents the whole.

Summary
Use imparcial when talking about not taking sides in a conflict (like a referee). Use objetivo when talking about sticking to facts without emotion (like a scientist). Use insesgado mostly in technical or formal contexts regarding data, statistics, or algorithms that are free from systematic distortion.
