Passive voice is typically more appropriate than active voice in various contexts such as academic, legal, or scientific writing for several reasons.

1. Emphasizing Results, Processes, or Facts: Passive voice allows the focus to be on the action or topic being discussed rather than the person or entity performing the action. This is useful when the emphasis is on the results, processes, or facts themselves rather than the individuals involved.

2. Neutrality and Professionalism: Passive voice helps ensure neutrality and professionalism in formal writing by creating a more objective tone. It removes the focus on the subject performing the action, thereby maintaining a sense of impartiality and avoiding personal bias.

3. Impersonal or Unknown Subjects: Passive voice is especially useful when the subject performing the action is unknown, irrelevant, or should not be the focus of the sentence. This can often be the case in scientific writing where the emphasis is more on the results or processes rather than the individuals carrying them out.

In academic, legal, or scientific writing, passive voice is favored because it allows for a clear and concise presentation of information while maintaining a professional and authoritative tone. It is an effective tool for conveying ideas objectively and ensuring that the focus remains on the content being discussed rather than the individuals involved in the research or writing process.
