I HATE certain "authority" sites which tease you with a headline then make you click through 10 pages with 2 lines of text and 5 ads on each to finish the topic.
I believe Google looks at word count and determines how long it would take for someone with an average reading level to read the article.
If that actual time is significantly lower than the time it should take, Google demotes the page.
In some niche's people will stick around and read long content, in some others, they won't.
One thing to keep in mind, though: Writing long, in-depth articles (and knowing how to make them enticing to readers) isn't a job for amateurs. It's harder than it looks.
