Krems reframes jealousy as an adaptive calibration system rather than a vice. Friendship jealousy scales with two inputs: how much you value the friend you stand to lose, and how much replacement threat a poacher poses. The practical model is a sweet-spot problem, like gift-giving: too small a signal ('hang out with anyone, I don't need you') tells a friend you don't value them and they drift to someone who does; too large a signal ('if you leave me I'll slit my wrists') reads as desperate and repels them. The skill is building an accurate meta-representation of where your friend ranks you, then behaving to that number. A calibrated jealous signal ('I love our friendship and I don't want to lose it') is a costly, vulnerable cue that can actually increase how much a friend values you.

Drawn from Dr. Jaimie Krems' evolutionary research on friendship jealousy and friend-guarding, discussed on Modern Wisdom #553.
Core principles
- 01Displayed jealousy and investment are costly signals of how much you value someone
- 02Both too little and too much investment push a friend toward someone else
- 03You are always estimating where a friend ranks you, and acting to that number
- 04Jealousy is adaptive information, not a character flaw to suppress
How to run it
- 1
Estimate your rank
Build an honest meta-representation of how much this friend values you, on a rough 1-to-10 scale. This estimate, not your anxiety, is the target for your behavior.
Pro tip Watch revealed preference: who they bring as their plus-one tells you more than what they say.
- 2
Read the replacement threat
Gauge how much a specific poacher could actually displace you. Time spent together matters less than whether the friend still prefers you when forced to choose.
- 3
Behave to your rank, not below it
If they value you at a 10, invest at a 10. Under-investing signals indifference and pushes them toward someone who values them properly.
Watch out Cold indifference ('I don't care who you spend time with') is read as you not valuing the friendship, not as security.

Cap the signal below desperation
Keep displays under the neediness threshold. A measured jealous cue signals value; a catastrophic one signals you can't function without them.
Watch out Over-the-top displays ('11 out of 10') read as desperate and can drive the friend away.
In the wild
Rather than either ignoring a friend's new attachment or issuing an ultimatum, you say: 'You're spending a lot of time with this other person, and I love our friendship and I don't want to lose it.' This sits in the sweet spot: it is a costly, vulnerable signal of exactly how much you value the friend. Krems notes a best friend might love hearing this and increase how much she values you, because the jealousy reads as a genuine measure of the friendship's worth to you.
→ Friend perceives high, sincere valuation and values the relationship more, rather than feeling smothered or dismissed.
Common mistakes
Signaling indifference to seem secure
Telling a friend you don't need them or care who they spend time with reads as low valuation and pushes them toward people who invest more.
Overshooting into desperation
Catastrophic displays of need ('if you leave me I'll die') read as instability and repel the very person you're trying to hold.
Is it for you?
Best for
People who over- or under-invest in close relationships and want to signal value proportionately.
Not ideal for
Casual acquaintances where high-investment signaling would read as strange or intense.
From the transcript
“she values me at a 10. I need to do behaviors at around a 10 because if I do behaviors at an 11 too much…”
“that is a cue of how much I value my friend and our friendship and my best friend might love that and increase how much…”
“I'm gonna feel more jealousy the more that I value the friend that I stand to lose”
