Silence is heavy. You’ve felt it in a room when someone accidentally mentions a "forbidden" topic, and suddenly, everyone is very interested in the texture of their napkins. We like to think we live in an era of radical transparency, where social media has stripped away every filter and left us with the raw truth of the human experience. Honestly, that’s just not true. Every culture, every era, and even every workplace has a list of the things we cannot say, and these linguistic boundaries shape our reality more than the words we actually use.
It’s about power. It’s about social cohesion. Sometimes, it’s just about not being a jerk. But the line between "polite society" and "censorship" is often thinner than we want to admit.
The Evolution of the Unspeakable
What was scandalous in 1950 is often a boring Tuesday morning conversation today. Think about mental health. My grandfather wouldn't have used the word "depression" if his life depended on it; he would have said he was "feeling under the weather" or "needed a bit of a rest." Today, we post our therapy breakthroughs on TikTok. We’ve moved the boundary.
But as we opened the door on health, we slammed it shut on other things. Harvard psychologist Steven Pinker has written extensively about how language serves as a signaling device. When we avoid certain phrases, we aren't just being quiet; we are signaling our membership in a specific "tribe." If you use the wrong terminology in a high-tech boardroom or a specialized academic setting, you aren't just "wrong"—you're an outsider. You've spoken one of the things we cannot say in that specific ecosystem, and the social cost is immediate.
I remember a specific instance during a corporate consulting gig. The company was failing. Everyone knew the product was outdated. Yet, in three months of meetings, not one person used the word "obsolete." It was a forbidden term. We called it "legacy-rich" or "mature." By refusing to name the problem, they made it impossible to solve. That is the danger of the unspoken.
The Science of "Verbal Taboo"
Why does it physically hurt to say something we know is forbidden? It’s not just in your head. Well, it is, but it’s in your amygdala. When humans encounter or contemplate breaking a social taboo, the brain’s emotional center lights up like a Christmas tree.
Neurolinguistics suggests that certain words—often profanities or deeply offensive slurs—are processed differently than "normal" language. They aren't just data points; they are emotional triggers. This is why a "slip of the tongue" can ruin a career in thirty seconds. We are wired to react to the forbidden with a level of intensity that far outweighs the actual vibration of the air molecules hitting our eardrums.
Professional Silences and the Cost of "Fitting In"
In the workplace, the things we cannot say often revolve around salary, incompetence, and the sheer boredom of the daily grind. We’ve all been there. You’re sitting in a "town hall" meeting, and the CEO is talking about "synergy" while the person next to you is quietly looking for a new job on their phone.
The most dangerous silence in business is the "Silence of the Experts." This happens when a junior employee sees a catastrophic flaw in a plan but feels that the hierarchy makes the truth unspeakable. The 1986 Challenger disaster is the textbook example. Engineers knew the O-rings might fail in cold weather. They tried to speak, but the organizational culture had effectively turned their technical warnings into the things we cannot say comfortably to those in charge of the launch.
We pay a "silence tax."
Basically, the more things you can't talk about, the more mistakes you make. If you can't talk about failure, you can't learn. If you can't talk about money, you can't get paid fairly. If you can't talk about being unhappy, you stay stuck in a life that doesn't fit you anymore.
The Weird Paradox of Modern Taboos
Here’s the kicker: we actually love having things we can’t say. It gives us a sense of safety. It creates an "In Group."
- In some circles, you can't question the efficacy of a specific diet without being branded a heretic.
- In others, mentioning your political leanings is the fastest way to get uninvited from Thanksgiving.
- Sometimes, it’s as simple as not mentioning an ex-spouse at a wedding.
Anthropologist Mary Douglas once described "dirt" as "matter out of place." Taboo language is just "words out of place." A swear word in a dive bar is invisible; that same word in a kindergarten classroom is an explosion. Context is the only thing that matters.

The Mental Toll of Keeping it In
There is a psychological weight to the unspoken. Research into "expressive writing" by James Pennebaker at the University of Texas at Austin showed that when people finally write down or speak the things they’ve been suppressed, their physical health actually improves. Their immune systems get stronger. Their blood pressure drops.
Keeping the things we cannot say locked in a vault inside your brain is a full-time job for your nervous system. It’s exhausting.
I’ve talked to people who held onto secrets for decades—affairs, debts, failures—and the moment they finally uttered the words, they described a literal feeling of lightness. The "unspeakable" only has power as long as it stays unspeakable. Once it’s out in the air, it’s just a sentence. It’s just words.
How to Navigate the Unspoken Without Ruining Your Life
So, what do we do? We can't just go around saying everything that pops into our heads. That’s called being a toddler, and it doesn't work well at the DMV.
The trick is distinguishing between social etiquette and destructive silence.
If you aren't saying something because it would needlessly hurt someone’s feelings (like telling your aunt her meatloaf tastes like a wet gym shoe), that’s just being a decent person. That’s etiquette. But if you aren't saying something because you are afraid of the truth, or because you’re protecting a broken system, that’s where the trouble starts.
Radical Candor vs. Reckless Honesty
Kim Scott, a former executive at Google and Apple, popularized the idea of "Radical Candor." The idea is simple but incredibly hard to do: Care personally, but challenge directly.
When we identify the things we cannot say in our relationships or jobs, we have to ask why they are forbidden.
- Is it forbidden because it’s offensive?
- Is it forbidden because it’s uncomfortable?
- Is it forbidden because it’s true?
If the answer is 2 or 3, it’s usually time to start talking.
Start small. You don't have to blow up your life in one day. If there’s a topic that feels "off-limits" with your partner, try saying: "I’ve noticed I feel weird bringing up [TOPIC], and I’m wondering if we can try to talk about it for five minutes."
Naming the silence is the first step to breaking it.
The Future of the Forbidden
As we move deeper into the 2020s, the list of the things we cannot say is shifting again. We are seeing a massive pushback against "polite silence" regarding corporate ethics, climate change, and wealth inequality. At the same time, we see new social codes emerging around identity and digital behavior.
Language is a living thing. It grows. It sheds old skin.
The "unspeakables" of the future will likely be things we haven't even thought of yet. Maybe one day, it’ll be taboo to talk about how much time we used to spend staring at little glass rectangles in our pockets. We'll look back and think, "I can't believe they actually discussed that in public."
Honestly, the most important thing you can say is the thing you’re most afraid of, provided it comes from a place of seeking clarity rather than causing chaos.
Actionable Steps for Breaking the Silence
If you’re feeling the weight of the unspoken in your own life, here is how to handle it without causing a total meltdown.
Audit your silences. Take a piece of paper. Divide it down the middle. On one side, list the things you want to say to people in your life. On the other, write down why you haven't said them. Are you afraid of rejection? Conflict? Being "canceled"? Seeing it on paper makes the fear look smaller.
Practice the "Three-Gate" rule. Before you speak a forbidden truth, ask: Is it true? Is it necessary? Is it kind? If it’s true and necessary, but not exactly "kind" (like giving tough feedback), focus on how to make the delivery as empathetic as possible.
Find a "Safe Word" space. Everyone needs one person—a therapist, a best friend, a journal—where there are absolutely no things we cannot say. If you don't have a pressure release valve for your thoughts, you're going to eventually explode at the wrong person at the wrong time.
Normalize "I don't know." In many professional circles, "I don't know" is a forbidden phrase. Change that. Admit uncertainty. It’s the most honest thing a human can say, and it usually opens the door for someone else to be honest too.
Watch for the "Elephant." When you’re in a group and you feel that tension, just name it. "I feel like there’s something we’re all avoiding talking about." You don't even have to say the thing. Just pointing out the silence usually breaks the spell.
The goal isn't to live a life without filters. That would be a nightmare. The goal is to make sure that you are the one in control of the filter, rather than the filter being in control of you. Stop carrying the weight of the things you're "not allowed" to say and start figuring out which truths are actually worth the breath they take to speak.
