How do you maintain objectivity and avoid letting your personal preferences overly influence your beta reading critique?

To maintain objectivity as a beta reader, I focus on the story's intent and goals, considering its target audience and evaluating it based on universal storytelling principles like character development, plot structure, and pacing. I avoid letting personal preferences influence my critique by balancing constructive criticism with positive feedback, framing concerns as questions rather than judgments, and separating subjective tastes from technical issues. I also make a conscious effort not to project my own writing style onto the manuscript, respecting the author’s unique voice and vision. This ensures my feedback is focused on helping the author improve their work, rather than based on personal bias.
