Jonathan Gottschall reviewing Miller's Spent in Seed:

Miller may have made this final point a bit too well. I was not many pages into Spent before I found myself helplessly attuned to Miller’s own “narcissistic self-displays.” Miller reminds us frequently of his elite education, tells us that he owns several thousand books, lets on about his sophisticated taste in avant-garde art, makes offhand displays of his mastery of musical jargon (“timbral richness,” “isorhythmic motets,” “polyphony”), stresses his impeccable liberal credentials, and shows off his authentic verbal flair, his cosmopolitanism, and his soaring IQ (he argues —tendentiously —that elite university degrees function as covert IQ guarantees). So Spent functions not only as an attempt to popularize a vein of scientific research, but also as a means of selling the audience on the virtues of its creator: Geoffrey Miller—a smart guy, a bit of a Renaissance man.

There are two things to say about this. First, it is Geoffrey Miller, Renaissance man, who gives Spent so much of its winning personality, its narrative tang, and its consistent good humor. Second, Spent cued me in not only to its author’s self-marketing, but also to my own. For what is a book review if not—at least in part—a narcissistic self-display? What am I doing now, if not flaunting my penetration, my learning, my tough-minded yet charitable judgment, and—most narcissistically of all—my ability to take a decade of Miller’s life as a scholar, scientist, and close observer of American pop culture, and wrap it up neatly in a 1,200-word package—complete with an artful, preening flourish at the close?

Jonathan clearly "gets it."  Let me also admit: my blog posts are no doubt also designed, at least unconsciously, to signal my many features.
