The Habituation Blues

This is the same thing I've been saying describes Jack's behavior from the start, just in the words of someone who spends more time researching why.

9. We can become bored with just about anything, but there may be a way to reverse the habituation blues. Researchers reporting in theJournal of Consumer Research think the trick is overcoming “variety amnesia”—our tendency to forget that we’ve been exposed to a variety of great things, be they people, food, music, movies, home furnishings or other—and instead focus our attention on the singular thing that no longer gives us the tingles. To shake ourselves free from this negative trap, we must “dishabituate” by forcing ourselves to remember the variety of things we’ve experienced. So, for example, let’s say that you’ve become bored with a particular musical group you once couldn’t listen to enough. This research suggests that what you need to do it recall the variety of other songs from other musical groups that you’ve listened to since the last time you listened to your once-favorite band, and by doing so you’ll revive appreciation for your fave.
