Romantic jealousy: evolved alarm, insecurity, or something you can unlearn?

October 6, 2026 · 13 min read

Evolutionary psychologist David Buss describes jealousy as an evolved response to threats to a relationship that runs from vigilance to violence, psychiatrist Paul Conti separates it from envy, Marc Brackett teaches people to tell the two apart and find the cause, sex researcher Aella describes managing jealousy inside polyamory, and Pastor Michael Todd ties it to self-worth. How you explain jealousy decides whether you treat it as information about the relationship, a problem in yourself, or a warning sign of danger.

Listen to this insight

The Short Version

The five experts here do not agree on what jealousy is, partly because they use the word for different things, and the answer you accept changes what you do about it. Evolutionary psychologist David Buss says romantic jealousy is an evolved emotion that guards a long-term bond, set off by real cues, and that the behavior it produces runs "from vigilance to violence" [1][2]. Sex researcher Aella still feels it inside polyamory and treats it as something to voice early and tell the truth about [5]. Marc Brackett treats it as a feeling most people have never named, and shows what happens when someone finally does [4]. Psychiatrist Paul Conti uses jealousy for the milder cousin of envy: wanting what someone else has without wanting to pull them down [3]. Pastor Michael Todd calls it part of human nature that is beaten by generosity and by owning your insecurities out loud [6]. Put together: the feeling is normal and often informative, it cannot simply be deleted, and what matters is the line between feeling it and acting to control or diminish another person.

What They Said

David Buss: an evolved alarm with real triggers

When Buss began studying jealousy, he says, it was treated as immaturity, insecurity, neurosis or pathology [1][2]. His argument is that it is an evolved emotion that protects the huge investment of a long-term relationship [1][2]. The background is his account of human mating: long-term pair bonds are rare among mammals, humans have them along with heavy male investment in children, and both sexes choose and compete [1][2]. An emotion that defends such a bond is, on this view, part of the design.

He lists what sets it off [1][2]:

  • Cues of infidelity.
  • Emotional distance, such as an "I love you" that goes unanswered.
  • Mate poachers, meaning rivals who show interest in your partner.
  • Mate value discrepancies. People tend to pair with partners of similar desirability. If one partner's value rises, say through career success, or falls, say through a long job loss, the higher-value partner becomes statistically more likely to cheat or leave, especially when the gap is large. So jealousy can flare even without any rival [2].

He also describes a difference in what hurts most. A former student analyzed the television show Cheaters and found that men confronting a partner first asked whether sex had occurred, while women first asked "do you love her?" [1][2] Men, Buss says, tend to be more upset by sexual infidelity, which threatens certainty of paternity, and women by emotional infidelity, which signals the loss of long-term commitment [1][2]. He stresses throughout that he is describing averages with many exceptions [1][2].

Then the dark half. Buss has identified 19 tactics people use once jealous, which he says "range from vigilance to violence." [1] Vigilance includes monitoring, hacking phones and stalking [1][2]. At the far end is intimate partner violence, which he says roughly 28 to 30% of married people in the United States will experience [1][2]. He is emphatic that he is not endorsing it and that it is illegal and wrong [1].

He describes the pattern so that it can be recognized. Verbal abuse, such as insulting a partner's appearance, and physical violence can function to lower a woman's perceived mate value so she is less likely to leave [1]. Controlling men often cut partners off from friends and family [1][2]. Verbal abuse predicts physical abuse [2]. Women also commit violence against men, often in self-defense or after discovering infidelity; men tend to cause more damage, and male victims are probably underreported [1][2]. About 80% of criminal stalkers are men, usually trying to win a partner back or to block her from finding someone else, and in a study of 2,500 victims the stalkers tended to be much lower in mate value than the people they stalked [1][2].

Can jealousy be removed? Buss's answer comes in his remarks on polyamory. He sees it as an attempt to satisfy some evolved desires while keeping others, like jealousy, quiet [2]. Couples set rules, often specific and arbitrary ones, but emotional connection often still triggers it [1][2]. One woman who did not mind her husband having sex with others became intensely jealous when she saw him holding hands with a former girlfriend [2]. His conclusion is that "we can't change our evolved sexual psychology", only activate some parts and keep others quiet [1].

On insecurity, he does not dismiss it. Speculating outside his main field, he says anxious attachment brings high "relationship load" and agrees that insecure people would probably be most upset by slow replies to messages [1][2]. Self-esteem, he suggests, may work partly as an internal gauge of one's own mate value, rising with a promotion and falling with rejection [2]. So for Buss the alarm is evolved, and how sensitive it is varies with the person.

Aella: feeling it anyway, and saying so

Aella practices polyamory, which she defines simply as not forbidding your partner from pursuing intimacy with others; what matters to her is the freedom, not whether it is used [5]. She is fine with conscious monogamy but objects to monogamy by default [5].

Her testimony matters because she has arranged her life around not acting on jealousy, and she still feels it [5]. Her method has three parts:

  • Report small twinges. She has learned to communicate even tiny ones, because she cannot predict which will grow [5].
  • Choose calm partners. She dates people who can stay calm when she is upset without treating her upset as a demand to change [5].
  • Prefer truth to reassurance. She actually prefers partners who do not reassure her, even telling her if they have a better time with someone else. Her reason is a line she quotes: "That which can be destroyed by the truth should be." [5]

She does not claim the feeling is a mistake to be trained away. She treats it as a signal to be spoken and examined, while refusing to let it become a rule that restricts the other person [5].

Marc Brackett: name it, then find the cause

Brackett, who directs a center for emotional intelligence, comes at jealousy as a problem of recognition. His framework asks people to recognize, understand, label, express and regulate emotions, and he argues that precise words point to the right response [4].

His example is his own father. His stepmother called to say his father was angry all the time. Over coffee, the father revealed that he resented his wife spending time helping her struggling children and grandchildren [4]. When Brackett named it as jealousy, his father began to cry, aware of his feelings for the first time, and his wife later said he was a changed man [4]. What looked like anger was jealousy over a partner's attention, and it changed once it had the right name and a known cause [4].

He separates jealousy from envy and both from stress. When Yale students constantly reported feeling stressed, he had them journal about it, and the most common underlying emotion turned out to be envy, driven by endless social comparison [4]. The label matters because the remedy differs. In the transcript he says that "when you're feeling chronic envy, you know, doing breathing exercises is not going to decrease the envy" and that you have to work on how you construct your relationships with people in your mind [4].

He does not treat envy as always harmful. He distinguishes momentary envy, which he uses to learn from speakers he admires, from envy that turns into resentment [4]. He and Andrew Huberman praise gratitude as perhaps the best antidote to envy [4].

Paul Conti: jealousy is the benign one

Conti's contribution needs a caution: he is not talking about romantic jealousy specifically. He uses the two words to mark a moral line [3].

Jealousy, in the benign sense he chooses, is noticing something someone else has and wanting it. In the transcript he says it is just a thought, "and it's a thought that can result in strivings or acceptance." [3] You might work harder to get the thing, or accept that you cannot have it and be all right anyway [3].

Envy is the other thing. "So it's completely different than envy, which is destructive." [3] Instead of working for what you lack or accepting it, you want to bring the other person down: "Take you down to where I am." [3] Envy, he says, never satisfies itself, and it comes from an intense sense of inadequacy, from deficits in the sense of self [3]. He believes it is the engine behind orchestrated evil, and he calls malignant narcissism "envy writ large." [3]

Lex Fridman disagrees with the clean separation. He argues that jealousy and envy are the same flame at different magnitudes, and in the transcript he brings in jealousy inside relationships as a neighbor to becoming toxic, which is in turn a neighbor to something worse [3]. As a teenager he noticed jealousy felt bad and was unproductive and learned to celebrate other people's achievements instead, which made him happier [3]. He worries that calling jealousy benign lets people off the hook [3].

Conti partly agrees, and his revised picture is useful. The mind is a landscape; feeling jealous brings you closer to the border of envy, and trauma pushes people toward it, but crossing the border is a qualitative shift and a choice [3]. We all may step over briefly, he says; the question is whether we come back [3]. He adds that childhood abuse teaches the lessons that the world is not safe and that you are not good enough, which heightens vigilance, fear and insecurity [3].

Michael Todd: human nature, answered with generosity and transparency

Todd, a pastor, speaks about jealousy twice in different senses [6].

As comparison, he says jealousy is part of human nature and is defeated by its opposite: celebrate others and give what you wish you had. "Generosity kills jealousy." [6] He also advises limiting exposure, since social media makes us jealous of things we would never otherwise have known about; racehorses wear blinders so they stay in their own lane [6].

As a feeling inside a couple, he handles it under the heading of transparency. He distinguishes transparency from honesty: "Honesty is when you ask me, I'll tell you the truth." [6] Transparency is offering it before being asked. His example is exactly a jealous moment: telling your partner that the way she talked to a man at the restaurant stirred up insecurities from a past relationship, without asking her to fix it [6]. That, he says, tends to draw empathy and deepen the relationship [6].

Underneath both is his view of worth. He describes his own performance-based scorecard, the sense that how well he does is how good he is, and his practice of admitting it, because "you can't heal what you won't reveal," [6] He locates his worth in his faith, and holds that each partner in a couple must keep working on their own insecurities [6].

Where They Agree, and Where They Don't

They agree jealousy is normal. Buss calls it evolved [1]; Todd calls it human nature [6]; Aella still feels it [5]; Conti says we all step toward the border [3].

They agree the danger is in what follows the feeling. Buss's spectrum of tactics [1], Conti's line between wanting and tearing down [3], Aella's refusal to turn her upset into a demand [5] and Todd's telling without asking her to fix it [6] all separate the emotion from control.

They agree saying it helps. Brackett's father changed when it was named [4]. Aella reports twinges [5]. Todd volunteers his insecurity [6].

They disagree on whether it is insecurity. Buss built his work against the view that jealousy is merely insecurity or pathology: it responds to real threats [1][2]. Todd and Conti trace the destructive forms to a wounded sense of self [3][6]. These are less opposed than they look. Buss himself says anxious people react more and that self-esteem tracks perceived mate value [1][2]. One account explains why the alarm exists; the other explains why some alarms go off constantly.

They disagree on whether it can be unlearned. Buss says the psychology cannot be changed, only quieted in part [1]. Aella's experience supports him: years of practice have not removed it [5]. Lex says he trained himself out of jealousy by celebrating others, and Todd prescribes generosity as a cure [3][6]. But Lex and Todd are mostly describing envy of other people's success, not fear of losing a partner. The sources suggest comparison can be retrained more readily than mate guarding.

They disagree on the words. For Conti jealousy is the mild form and envy the destructive one [3]. For Buss jealousy is the emotion whose tactics include violence [1]. For Brackett jealousy concerns a partner's attention and envy concerns comparison [4]. Lex thinks the distinction is one of degree [3]. A reader should check which meaning is in play before applying anyone's advice.

They disagree on reassurance. Aella does not want it and prefers hard truths [5]. Todd expects that disclosing insecurity will draw empathy [6]. Each reflects what the person is protecting: Aella wants accurate information, Todd wants closeness.

Why It Works

Why the alarm exists. A long-term bond is a large investment that can be lost to a rival or to a partner's departure. Buss argues that an emotion alert to those cues would protect it, and that the sexes weight sexual and emotional threats differently because the costs differ [1][2].

Why it can fire without cause for blame. Mate value shifts, such as a promotion or a job loss, change the statistical risk even when nobody has done anything [2].

Why it turns ugly. Buss describes abuse and isolation as tactics that lower a partner's options and visibility to others [1][2]. Conti describes the general move of feeling better by bringing someone down, rooted in inadequacy [3].

Why naming works. Brackett's claim is that an emotion understood and labelled accurately can be regulated, while a mislabelled one, anger or stress in his examples, gets the wrong treatment [4].

Why honesty works. Small feelings reported early do not have time to grow, in Aella's experience [5]. Hidden things, Todd says, rot [6].

Why generosity works on comparison. Todd and Brackett both hold that acting from the opposite stance, celebrating, giving, being grateful, undoes envy [4][6].

Where It Applies, and Where It Doesn't

Buss's account concerns romantic jealousy and is a description of averages, not a justification; he says explaining a behavior is not endorsing it [1][2]. Treating jealousy as information is reasonable when the cues are real. It is not a licence to monitor a partner, which Buss places on the same spectrum as stalking [1].

Conti's and Todd's remarks are mainly about comparison with others, so their remedies fit envy of a friend's success better than fear of infidelity [3][6]. Aella's method assumes partners who have chosen non-monogamy and can tolerate blunt truth; she does not offer it as a rule for everyone [5].

Where jealousy shows up as insults about your appearance, checking your phone, cutting you off from friends and family, or any violence, the sources describe a pattern that escalates [1][2]. That is a safety matter, not a communication problem. Anyone in that situation should contact a domestic violence service, a doctor or the police. Someone who cannot stop acting on jealous urges should see a mental health professional.

What To Do With It

  1. Name it precisely. Ask whether what looks like anger or stress is jealousy over a partner's attention, or envy of what someone else has [4].
  2. Look for the trigger. Check Buss's list: a real cue of infidelity, emotional distance, a rival, or a shift in one partner's standing [1][2].
  3. Say it early and small. Report the twinge before it grows, as Aella does [5].
  4. Offer it without a demand. Use Todd's form: this stirred up an insecurity of mine, and I am not asking you to fix it [6].
  5. Ask for the truth, and be ready to hear it. Aella's standard is that what the truth can destroy should not be protected [5].
  6. Do not monitor. Checking phones and tracking movements are the first steps on Buss's spectrum [1].
  7. Treat insults and isolation as warnings. Verbal abuse predicts physical abuse, and being cut off from friends and family is a known control tactic [1][2].
  8. Work on your own worth separately. Todd and Conti both locate the destructive forms in a sense of inadequacy, and Todd recommends counseling [3][6].
  9. For comparison envy, practice the opposite. Celebrate, give, keep a gratitude habit, and limit the feeds that supply the comparisons [4][6].
  10. Notice when you want to bring someone down. That is Conti's border between jealousy and envy, and crossing it is a choice [3].
