That's the benefit of online linkable texts as opposed to books.

On the net, if you want to mention a Sequence post or a Wikipedia article, you just link to it and the reader either knows or can quickly check whether they've read it before.

In a book, if you just name-drop something like "evo-psych", the reader might have a very different, limited, or wrong conception of the subject. If you refer to another book or article that explains the subject, the reader isn't likely to have read it unless it's a very famous textbook or popular exposition (like The Selfish Gene), because there are many equally good books on any subject. So for the reader to make sure they're on the same page as the author, the book must include a long explanation of the subject referred to - even if it's not the actual topic and author would rather leave it out.
