What does it mean by critical literature review should be balanced?

A balanced critical literature review means that the review should present a fair and objective analysis of the existing literature on a particular topic. This includes considering and discussing different perspectives, arguments, and findings from various sources without bias or prejudice. It also involves acknowledging the strengths and weaknesses of each study or source, and providing a comprehensive overview of the current state of knowledge on the topic. A balanced review should not only focus on supporting one particular viewpoint or argument, but should instead provide a well-rounded and nuanced understanding of the topic by considering multiple viewpoints and interpretations.
