Signal Amplification and the Spiral of Overthinking
Exploring the sneaky psychological effect that makes you overestimate how much people notice or care about what you do.

Ever sent a message in a group chat, then sat there in silence as no one responded, and suddenly youâre spiraling?
đ
Did I say something weird?
đ
Did I offend someone?
đ
Are they all talking about it in a separate chat without me?
Or maybe you made a tiny mistake during a presentation, stumbled over a word, showed the wrong slide, and spent the rest of the day obsessing over it. Lmao if youâre an over thinker like me I know this resonates. You imagine your coworkers whispering about it in the break room or your manager secretly docking mental points from your performance review.
The truth?
Nobody noticed. And if they did, they probably forgot about it 30 seconds later.
But your brain didnât forget. It grabbed onto that moment like a headline-worthy scandal, convinced it was the talk of the day. Thatâs the magic (and curse) of signal amplification bias: our mindâs habit of turning the volume way up on how much we think people notice or care about our words and actions.
Itâs like walking into a party with a coffee stain on your shirt, convinced that everyoneâs eyes are glued to it, when in reality, theyâre too busy worrying about their own metaphorical moments.
So why do we do this to ourselves? And how can we dial the signal down to something closer to reality?
Letâs dig in.
The Research Behind It
This idea isnât just in your head. Ironically, thatâs exactly where it starts.
Psychologists Thomas Gilovich, Victoria Medvec, and Kenneth Savitsky explored this phenomenon in a classic 2000 study titled "The Spotlight Effect in Social Judgment.â In one experiment, participants were asked to wear an embarrassing T-shirt (featuring Barry Manilow) and walk into a room of strangers.
The wearers predicted that about 50% of observers would notice the shirt.
In truth? Only about 25% did.
The researchers coined this overestimation as the "spotlight effect," a closely related bias showing how we amplify the perceived "signal" of our actions in others' eyes.
This illustrates how we amplify the perceived signal of our actions, we assume people notice us more than they actually do.
Why It Happens
1. Society teaches us to monitor ourselves
From a young age, we learn what's "acceptable" through rewards, punishments, and silent disapproval. Whether it's how we speak, dress, succeed, or show emotion, weâre constantly being measured, often in invisible ways.
You learned to overthink because, at some point, not thinking things through led to pain: rejection, embarrassment, criticism, exclusion.
2. Lived experiences reinforce that some mistakes arenât safe
Especially for people from marginalized or high-stakes environments, the cost of being âwrongâ or âdifferentâ is higher. That means more pressure to pre-analyze everything: what you say, how you act, who you trust.
If youâve been shamed, misunderstood, or dismissed, your brain starts running simulations: âHow will this be taken? Should I say it differently? What if they think less of me?â
Thatâs overthinking, but with a purpose: survival.
3. We internalize judgment through norms
Social norms are often silent rules: be confident, not arrogant; be thin, but not too thin; be ambitious, but likable. These double binds are impossible to navigate without internal conflict.
So, over time, we absorb the gaze of others into our own minds. Even when no one is watching, we police ourselves. This is why we feel judged. Weâve learned to pre-judge ourselves before others get the chance.
âWhat will people think?â becomes automatic, even when no one says anything.
4. Overthinking becomes a coping strategy
In a world that rewards performance and punishes vulnerability, overthinking feels like a way to stay in control. Itâs a mental strategy: if you can anticipate judgment or rejection, you can avoid it.
But the downside? It disconnects you from spontaneity, authenticity, and rest.
Understanding signal amplification bias is freeing. It reminds us that:
Most people are too focused on themselves to scrutinize us.
A moment of awkwardness is rarely remembered by others.
We often carry more self-judgment than is necessary.
So the next time you're caught up in a replay of that âcringeâ moment, pause and ask:
Am I amplifying this signal, or is it actually that loud?
We all live at the center of our own story, but in most other stories, weâre just extras.
And thatâs liberating. So the next time you want to crash out, donât. Itâs literally fine, and youâll live to see another day.
