What is the author's style in The Zombie Survival Guide by Max Brooks?

Brooks uses scientific and formal language to convey the impression of a researched and documented survival guide. The narrator portrays himself as an expert, someone whose opinions can be trusted and relied on, even in the deadliest encounters with zombies. Because of this, the author uses the language of science to sound informed and intelligent. The fictional world of the novel requires its narrator to be trustworthy and believable, even though he is talking of fantastical things.

However, instead of being merely straightforward and informational, his language also reveals the character and point of view of the narrator. The narrator uses questions to echo the common wisdom or knee-jerk reactions that people have regarding zombie-related issues. Wouldn't plate mail armor provide total protection? Wouldn't a car be the best way to zoom through zombie territory? The author puts forth these questions and then knocks them down, showing the reader that a knee-jerk reaction or first guess is seldom the most intelligent response.
