One might snigger and wink at a person who says that he bought Playboy for its articles, but chances are that he’s dead serious about it. And he’s not alone. There are hundreds of thousands of them who used to buy that men’s “entertainment” magazine for the same reason.
So, what gives?
The key to understanding this delightful paradox lies in the word “Salience”. The dictionary meaning of Salience is the quality of being particularly noticeable or prominent.

The reason why the articles were memorable was because they were interspersed between titillating pictures. That’s what made them salient.
If you’ve ever made a powerpoint presentation, you’d have noticed that slides that are different from the rest or at least their preceding or following slides are better remembered by your audience. If you’re one of the smarter ones, you’d have leveraged this knowledge to deliberately draw attention to the important points you wish to make.
This principle of Salience could also be the reason why the beginnings and endings of books stick to the mind more than the middle – because there are elements at only on one side of them, instead of both.
