Wanting vs. Liking: Why You Crave What You Don't Enjoy

It's late, the laptop is open on the bed, and you already know how this goes. You'll scroll and skip, hunting for the right video, and half an hour later you'll be lying there feeling flat and wide awake, wondering why you bothered.

Why does the pull feel so huge when the payoff feels so small?

Brain research has a surprisingly specific answer. Wanting something and liking it are two different experiences, and they run on two different systems. Once you can tell them apart, behavior that feels baffling starts to make sense, and you get a few practical ways to work with it.

Wanting and liking run on different systems

Robinson and Berridge proposed what's now called incentive-sensitization theory in 1993. The work that followed, much of it from Kent Berridge's lab at the University of Michigan, pulled apart two things most of us lump together.

Wanting is the pull. Researchers call it incentive salience: the sense that something matters right now and you need to go get it. It leans heavily on dopamine and recruits big, widespread brain systems. Liking is the pleasure itself, the moment something actually feels good. It's made in small “hedonic hotspots” that use opioid and endocannabinoid signals, the brain's homemade cousins of morphine and cannabis.

The most striking evidence comes from rats. Rats with almost all their dopamine depleted still show the facial reactions of “liking” when they taste sugar. As far as anyone can tell, they still enjoy it. But they won't work to get it. The pleasure is still there; the drive to go after it is gone.

Most of the time the two systems agree. You want a taco, you eat the taco, you like the taco. But the theory's name hints at its central idea: with repeated exposure, the wanting system can become sensitized, reacting more and more strongly to the cues linked to a reward, while liking doesn't grow along with it. Wanting can pull ahead on its own.

More desire, not more liking

Valerie Voon's team at the University of Cambridge looked at this with porn in 2014. They scanned 19 men with compulsive sexual behavior and 19 healthy volunteers while both groups watched explicit videos.

The men with compulsive sexual behavior showed more activity in the ventral striatum (a hub of motivation and reward), the dorsal anterior cingulate, and the amygdala, which flags what's emotionally important. Then came the part that matters here. They reported more desire than the volunteers did, but not more liking.

Their brains were pulling harder. The videos weren't any more enjoyable.

A companion study from the same Cambridge group, led by Mechelmans, found an attentional bias in men with compulsive sexual behavior: their attention was pulled faster toward explicit images. If a thumbnail has ever grabbed your attention before you'd decided to look, that's the kind of pull they were measuring.

Then, in 2017, Gola and colleagues compared 28 heterosexual men seeking treatment for problematic porn use with 24 men who weren't. In the scanner, the men saw cues that predicted what was coming next: an erotic picture or money. The treatment seekers' ventral striatum reacted more strongly to the cues that predicted erotic pictures. It didn't react more to the cues for money. And when the pictures themselves appeared, there was no difference between the groups. The stronger someone's response to the cue, the more severe their porn use tended to be.

That's the heart of this whole topic. The difference wasn't in the reward. It was in the anticipation, the moment a signal said something good might be on the way. (This fits with what dopamine mostly does, which has more to do with prediction than with pleasure, but that's a story of its own.)

These are small studies, all of men, and a brain scan taken at one point in time can't tell us which came first. Still, the systems involved are basic equipment, shared even with rats, and the studies point the same way: when porn use feels out of control, the problem looks less like too much pleasure and more like too much pull.

What the gap means for you

If you've ever thought, “I don't even enjoy this that much, so why can't I stop?”, you've described the gap between wanting and liking almost word for word. You're picking up, accurately, on two systems that have drifted apart. Nothing about that makes you weak or fake.

It also shows you where you have room to act.

Wanting is loud, but it has two soft spots. First, it's cue-driven. It fires at signals: the phone in bed, a certain app, an empty apartment after a rough day, a particular hour of the night. Fewer cues means fewer sparks. Second, it's temporary. Clinicians who teach urge surfing often describe a craving as a wave that rises, peaks and fades, usually within about 20 to 30 minutes if you don't feed it, often sooner. That's clinical experience rather than a lab measurement, but it's worth testing for yourself.

Liking needs something else entirely: room. When a big share of your evenings goes to chasing one intense thing, everyday pleasures can start to feel muted by comparison: a good meal, a walk, music, a long conversation, being close to someone. Those are worth rebuilding on purpose, because they give the liking system something to work with.

Practical steps that follow from the science

• Rate wanting and liking separately. When the pull hits, score how much you want it, from 0 to 10. Afterward, or thinking back to the last time, score how much you actually liked it. Write both numbers down, in your Journal or anywhere private. After a week or two you'll have your own data on the gap, and the craving gets a little less mysterious.

• Cut cues before they fire. Gola's study suggests the big reaction happens at the signal, not at the screen. Work on the signals instead: charge your phone outside the bedroom, log out of the accounts that start the spiral, and change the routine around your riskiest hour.

• Give the wave time. When a cue gets through, you don't have to win a debate with it. Name it (“this is wanting, not liking”), get your body moving, and let 20 minutes pass. Each time the wave passes without the usual ending, you're practicing a new response to an old signal.

• Feed the liking system on purpose. Pick one simple pleasure a day and pay full attention to it: the first sip of coffee, a song with the volume up, sun on your face. It sounds minor, and that's fine. It's practice for a system that's been getting crowded out.

One more thing. If very little has felt enjoyable lately, and you've felt down most days for two weeks or more, or lost interest in things you used to enjoy, talk to a doctor or therapist. That deserves its own attention. If you have thoughts of harming yourself, contact local emergency services or a crisis line now.

Next time it's late and the pull starts, ask two questions instead of one. How much do I want this right now? How much did I actually like it last time? Write both answers down, then give the next 20 minutes to something else.
