Um… Why Are We Like So Afraid to Sound Human?

“Like… um… I think…”

Most of us have stumbled over a sentence like this before and cringed immediately. Next comes the sudden replay as you berate yourself for the slip-up. Why did I say “like” again? Did that make me sound dumb? Should I have paused instead? I shouldn’t have said anything.

Filler words (like, you know, uh, so, basically) frequently come up in day-to-day conversation. Used to soften statements and signal hesitation, they help keep conversational flow. Filler words can even help with processing information. That humiliating “uh” was actually a signal that an important piece of information was to follow. This improves listeners’ memory and comprehension in the long run. 

So why the backlash? 

In professional and academic settings, filler words are heavily criticized, especially in interviews and presentations, where seamless execution indicates competence. In these formal settings, articulation is important. A speech littered with “likes” and “uhs” can get lost. 

But this critique extends beyond clarity. 

Filler words are often synonymous with uncertainty and immaturity. Certain words, particularly “like,” have long been associated with young women and are, as a result, deemed frivolous and unintelligent. In response to this dismissive attitude, linguists have pointed out the word’s functions for introducing approximations and dialogue. But despite its complexity, “like” is still ridiculed.

Yes, overusing filler words can impede clarity. But that pragmatic critique doesn’t justify the shame the habit carries. We don’t review our speech—we police it. 

So what are we really striving for: clarity, or perfection?

In a world hyperfixated on polish, hesitation is failure. Social media augments our inner voice, framing hesitation as inadequacy. It honors seamless delivery, rehearsed soundbites that never falter or reveal the messy hesitation that comes with thinking. Every um is amplified, every like is permanent when we’re constantly watched. Speech is no longer just about communication: it’s a performance. 

We are afraid to sound human, because “human” means “flawed.” Filler words are instinctive. But we repress our authentic selves because we’re programmed to see humanity as a defect. Since childhood, we’re taught to value perfection over realness. In presentations, you must speak smoothly to receive full marks; in seminars, you must answer and avoid hesitation so as not to be judged. We hesitate not because we can’t think, but because we know that contemplation garners more judgment than silence. So, silence becomes safe. 

“Like,” “um,” “I think,” aren’t weaknesses; they’re the mind’s whirring gears at work. It’s thinking in real time. It’s not pretty, it’s not scripted—it’s human. As linguists have noted, filler aids in our communication every day. The hesitation was never a failure of communication, it was proof of it. We mistake smooth delivery for intelligence when true intelligence is our boldness to speak before the perfect word comes to mind. Every time we silence our thoughts, we lose something far more than a stray syllable; we lose the chance to think, to speak, and ultimately, to be human.
