Point of view is the author's (or speaker's) perspective when presenting information or telling a story. The "voice" that a writer speaks in plays an important part in how well they disseminate information. Various disciplines utilize viewpoint and voice in various ways:

If you’re writing an analytical or research essay (common in the humanities), use the third-person point of view: Achebe argues… or Carter describes her experiences as…

Scientists (including social scientists) tend to use third-person point of view as well because they depend largely on quantitative research to present their findings or support their opinions: The results indicated…

Occasionally, social scientists and writers in the humanities will use first person to discuss their own experiences while doing research or if writing part of a personal narrative as evidence: After spending a year living with the Upendi, I came to the conclusion that…or Every Christmas we went to the same place, as if our memories could be rekindled…

What does "third person" point of view mean?

The third-person voice is ideal for factual reporting, in journalism or for academic research. It helps present information objectively (and not biased) by not having to use personal pronouns (I, me, my, you, etc.). This voice and perspective prioritizes the subject matter and diminishes the opportunity for a relationship to be established between the author and the reader.
