It requires a writer to do a vast amount of research to help support his ideas, to write in an official-sounding manner stating opposite viewpoints using facts and data only. It also requires adherence to some rules of language like refraining from using personal pronouns as it might indicate personal feeling and emotive words that might indicate an opinion on the part of the writer, avoid contractions and use passive voice.
The word choice in this tone needs to be considered carefully using words that are precise, objective, appropriate and impersonal, avoiding judgemental words and slangs, as it is used when a writer wants to deliver information in a neutral, factual and unbiased way so void asking questions too.
