If you dislike someone, the logical thing would be to avoid them. Yet human beings often do the opposite.
At work, you notice what that irritating coworker is doing. If you discover their social media account, you may find yourself checking it. If you hear that something went wrong for them, you suddenly want the details.
We normally expect attention to follow affection. So why spend limited time and mental energy on somebody we cannot stand?
The easy joke is, “Maybe you secretly like them.” Psychology suggests something considerably more complicated.
For the human mind, “I dislike this person” does not necessarily mean “this person is irrelevant.” In some situations, dislike can make someone more difficult to ignore.
People we dislike can become people the brain considers worth monitoring
One useful starting point is the broader psychological tendency sometimes summarized as negativity bias.
In a major review published in 2001, Roy Baumeister and colleagues argued that across many areas of psychology, negative events, emotions and information often have a stronger effect than comparable positive ones.
That does not mean the brain contains a simple switch labeled “pay attention to people you hate.”
But from a practical perspective, negative information can matter enormously.
If someone makes you feel threatened, undermines you, competes with you or repeatedly creates trouble, knowing what that person is doing may have value.
Imagine two coworkers.
One is pleasant but has almost no influence over your work.
The other annoys you, criticizes you and may affect how your manager sees you.
Which person’s behavior are you more likely to monitor?
You may not be watching because you like them. You may be watching because your mind has classified them as socially important.

The harder an “enemy” is to escape, the more attention they may receive
A particularly interesting study by Liman Man Wai Li, Takahiko Masuda and Hajin Lee examined how relational mobility affects people’s motivation to understand enemies.
Relational mobility refers, roughly, to how easy people believe it is to form new relationships and leave existing ones.
If you can simply walk away from a difficult person and replace that relationship, monitoring them may not be especially useful.
But what if you cannot?
Your boss will still be there tomorrow.
Your coworker remains in the same department.
Your relative will appear at the next family gathering.
Your classmate will still be sitting three desks away.
Across three studies, the researchers found evidence that lower relational mobility was associated with greater motivation to understand enemies.
In one experiment using a hypothetical workplace, participants who were led to perceive lower relational mobility spent more visual attention on enemy characters during an eye-tracking task. In another experiment, they were more accurate at later recognizing the enemies’ faces.
That distinction matters.
The study does not prove that every person watches everyone they dislike. It shows that when difficult relationships seem harder to replace or escape, paying attention to an adversary may become more useful.
Sometimes “I hate that person, so I want nothing to do with them” competes with another instinct: “I hate that person, so I need to know what they are doing.”
AI-generated conceptual illustration. The evolutionary imagery is metaphorical; the cited research examined social relationships and attention, not prehistoric human behavior directly.
Trying not to think about someone can keep them in your head
Then there is a second problem.
After becoming angry with someone, we often give ourselves a perfectly reasonable instruction:
“I’m done. I’m not going to think about them anymore.”
Unfortunately, thought suppression has a history of behaving badly.
Daniel Wegner and colleagues demonstrated this in the famous 1987 “white bear” experiments.
Participants were asked to avoid thinking about a white bear. Suppressing the thought proved difficult, and under experimental conditions the suppressed thought could subsequently rebound.
This does not mean that Wegner proved that trying to forget a hated coworker will always make you obsessed with them. The study involved a deliberately simple thought-suppression task, not hostile relationships.
But it revealed an awkward feature of cognition:
To check whether you are successfully not thinking about something, part of the mind must keep checking for that very thought.
“Don’t think about him.”
Did I think about him?
There he is again.
Our attempted eviction can accidentally become a renewal of the lease.
Rumination can make the argument continue after the other person has gone home
There is also a difference between briefly noticing an unwanted thought and repeatedly replaying an interpersonal conflict.
Research by Michael McCullough, Giacomo Bono and Lindsey Root followed people after interpersonal transgressions and found that increases in rumination about the offense were associated with reduced forgiveness, with anger playing an important mediating role.
Again, correlation and temporal relationships in this research do not mean that every angry thought inevitably causes lasting resentment.
But the basic pattern will feel familiar to almost anyone who has had a serious argument.
The other person leaves.
The argument does not.
You replay what they said.
You improve the comeback you should have used.
You imagine the next confrontation.
You discover another reason they were wrong.
The person may no longer be physically present, but your mind keeps inviting them back for another meeting.
At that point, hatred becomes expensive. The other person gets your attention without even being in the room.
Social media turned checking someone you dislike into a frictionless habit
Then humanity invented the smartphone.
Previously, finding out what a disliked former coworker, acquaintance or rival was doing required effort. You needed mutual friends, gossip or an accidental encounter.
Now it can take three seconds.
Open Instagram.
Search the name.
Scroll.
Confirm that they still annoy you.
Close the app.
Repeat next week.
Researchers have even begun examining this behavior under the label “hate-following.”
A 2023 study led by Cleoputri Yusainy surveyed 560 undergraduate Instagram users. Participants recalled an episode involving envy, and the researchers examined hate-following motives alongside different forms of envy, hate and schadenfreude — pleasure at another person’s misfortune.
The study found positive associations between hate-following motives and several of these responses, including malicious envy and schadenfreude.
However, the result needs perspective.
This was a study of undergraduate Instagram users, not proof that everyone who checks an irritating person’s profile is motivated by envy or secretly enjoys their suffering.
“Hate-following” is also a relatively new research topic rather than a settled psychological diagnosis.
Still, the phenomenon itself is recognizable.
Social media did not invent curiosity about people we dislike. It removed most of the effort required to satisfy it.

A disliked person can also become an uncomfortable measuring stick
Threat is not the only reason somebody remains interesting.
Comparison matters too.
Consider a stranger you dislike who lives on another continent, works in an unrelated field and has absolutely no effect on your life.
They may be easy to forget.
Now imagine someone your age, in your profession, doing work similar to yours.
Suddenly their promotion matters.
Their salary is interesting.
Their audience size matters.
The praise they receive feels suspiciously important.
“Why are they doing better than me?”
The disliked person has become more than an unpleasant character.
They have become a ruler against which you measure yourself.
This helps explain why online rivals, former classmates, competitors and disliked creators can occupy so much mental space.
The emotion may be negative, but the comparison is personally relevant.
Does intense hatred really mean someone secretly loves the other person?
Popular culture loves this idea.
“Love and hate are two sides of the same coin.”
“If you hate them that much, you must care about them.”
There is a small piece of neuroscience that makes the comparison interesting — but not enough to turn the cliché into a scientific law.
In 2008, Semir Zeki and John Paul Romaya used fMRI to study 17 participants while they viewed photographs of people they intensely hated.
The researchers identified a pattern of brain activity associated with viewing hated individuals.
Some activated areas — particularly the putamen and insula — overlapped with regions previously reported in research on romantic love.
But the researchers were equally clear that the overall patterns for hate and romantic love were distinct.
So “science proves love and hate are the same” would be nonsense.
The more interesting interpretation is simpler.
Both a deeply loved person and a deeply hated person can be highly significant to us.
The similarity may not be affection. It may be importance.
AI-generated conceptual illustration. Love and hate are not scientifically identical; the image represents the idea that both can make another person psychologically significant.
The true opposite of obsession may be irrelevance
There is a famous saying that the opposite of love is not hate but indifference.
It sounds psychologically profound, but it should not be mistaken for a formal scientific law.
Still, there is something useful hidden inside it.
Think about all the people you once disliked.
Some probably still irritate you.
Others have disappeared almost completely from your mental world.
You do not forgive them every morning.
You do not actively hate them.
You simply do not think about them.
That is a very different state.
If you love somebody, you willingly give them attention.
If you intensely dislike somebody, you may unwillingly give them attention.
Either way, attention is a limited resource.
And every minute spent checking whether the person you hate has embarrassed themselves is still a minute of your own life being spent on them.
A person may finally be out of your life not when you can say “I still hate them,” but when somebody mentions their name and you realize you have not wondered what they were doing for months.
So why do we watch people we hate?
There probably is no single answer.
Sometimes we are monitoring a social threat.
Sometimes the relationship is difficult to escape.
Sometimes our attempts to suppress the thought keep bringing it back.
Sometimes we are ruminating over an unresolved conflict.
Sometimes the other person has become a comparison target.
And sometimes social media has simply made satisfying a bad curiosity ridiculously easy.
What psychology does not tell us is that secretly following someone means we secretly love them.
That explanation is much too neat.
The more uncomfortable possibility is that hatred itself can assign importance.
We keep looking because, for one reason or another, we have not yet decided that this person is irrelevant.
And perhaps that is the strangest thing about disliking someone.
You want them out of your life.
Meanwhile, your attention keeps letting them back in.
Editor’s Note
There is something wonderfully pointless about deliberately opening the social media account of someone you dislike, reading their latest post, getting irritated and then thinking, “Yep. Still can’t stand them.”
Yet people do exactly that.
Sometimes we can remember an irritating person’s words more precisely than something said by someone we actually like.
That makes me think the ultimate victory over a person you dislike may not be continuing to hate them with greater skill.
It may be reaching the point where someone asks, “Whatever happened to that person?” and your genuine response is:
“Actually, I have no idea.”
