Recent studies show that when people in relationships experience attraction to someone else, desire can boomerang back and increase feelings for their actual partner. Esther Perel has described this dynamic for years. Now it has data behind it.

Huberman reveals that Instagram is reportedly the world's largest dating app by a wide margin — a fact that recontextualizes the infidelity risk of social media entirely. Eastwick then lays out two simultaneous processes at work in committed relationships: the derogation of alternatives (happy partners rate attractive others as 'weak sauce') and the 'playing with fire' of seemingly innocent messaging that escalates. [1] — Paul Eastwick "When you're in a happy relationship, your brain downgrades alternative partners — you see them as less desirable than anyone else would. It…" 2:06:40 He also cites recent studies showing that attraction to an alternative can rebound and increase desire for one's actual partner — the data behind Esther Perel's framework. The key distinction, Eastwick argues, is between the fact of attraction (unavoidable, not dangerous) and the repeated follow-through on that attraction (what actually erodes the protective mechanism and creates infidelity risk). He adds a practical note: couples can benefit from acknowledging the reality of attraction without acting on it — a form of healthy compartmentalization.
According to an expert source cited by Andrew Huberman, Instagram is effectively the world's largest dating app by an enormous margin, with much of its time spent in DMs that lead to real-world meetings.
Take every measurable trait two people have in common, run the math, and your ability to predict whether they'll click is barely better than random chance. Dating app compatibility algorithms are built on a premise that the science doesn't support.
Objective similarity measures — the kind dating apps use to match people — predict whether two people will click at barely better than coin-flip odds.
When you're in a happy relationship, your brain downgrades alternative partners — you see them as less desirable than anyone else would. It's not delusion; it's a built-in protective mechanism. And it's why the marketplace metaphor for attraction ultimately breaks down.
The danger in infidelity isn't the initial moment of attraction — it's the repeated follow-through. Each subsequent conversation with someone you're attracted to erodes the protective mechanism that keeps your partner at the center of your desires. Instagram made this process frictionless.
Predictions that AI would eliminate radiologists were spectacularly wrong. Since those predictions, Mayo Clinic's radiology staff grew 55% and the specialty became the second-highest paid in medicine. The reason: AI automated scan-reading, but only 36% of a radiologist's time was ever spent doing that.
Self-help fails because people are sold one universal cure by the hyper-responders who had a transformative result from it. The real problem is context: every method works for the right person at the right time, which is almost never you just because the author says so.
Spencer Greenberg was once so socially anxious his heart pounded just approaching a stranger. His therapist gave him homework: go to a bar alone, talk to 5 strangers. Starting with asking for the time, he worked up to asking men for hugs — and his anxiety fell dramatically in 6 months.
A person who flies regularly but obsessively checks weather forecasts before every flight is not doing exposure therapy — they're teaching their brain that flying is only safe with the ritual. Safety behaviors prevent the brain from ever learning that the feared thing is actually fine.
The worry-time technique assigns all worries to one scheduled slot (e.g. 5 PM). Every time a worry surfaces, you write it down and ban yourself from engaging with it until that time. When 5 PM arrives, most worries feel trivial and the act of batch-worrying exposes how little it actually accomplishes.
In a randomized study of 20 habit techniques, 'habit reflection' stood out: recall a past habit you successfully built, write down what helped you succeed, then apply those same strategies to your new habit. It works because it's self-adapting — it uses whatever worked for YOU.
The tiny habits technique — always having a minimal version of your habit you can do when life gets in the way — keeps the mental machinery of habit formation from breaking. Paradoxically, people given a tiny-habit fallback option were MORE successful at the full habit, not less.
Fears and worries act like playground bullies — they want to ambush you. But when you deliberately seek them out and choose the time of engagement, they lose their power. The volitional act of starting the fight on your own terms is one of CBT's most underappreciated insights.
Most downtime defaults are things you regret immediately after — phone scrolling, binge TV. 'Glad you did it' activities meet the same need for rest but leave you feeling like you spent your time well. The switch from a bad screen to a documentary, a book, or a walk costs almost no extra effort but compounds into identity over time.
