Why ChatGPT Loves—& Some Humans Hate—em Dashes

I hope to clarify a curious trend that caught my attention several times over the last few weeks on LinkedIn: different people—mostly mediocre copywriters begging for employment—complained about ChatGPT’s obsessive preference for em dashes. Their prevalent sentiment was predictably negative (they still think they lost their jobs to AI instead of their own incompetence); however, as I saw more people contribute in similar ways, my own surprise grew. See, I don’t just appreciate ChatGPT’s use of em dashes—I love it. Now, here are some reasons why using the em dash is a good idea, and why some may have a problem with it.

No cliff-hangers, bait-and-switches, or other cheap sales tricks. The reason why a lot of humans don’t like the em dash is because it implies a swift motion, an abrupt change. This punctuation mark aligns well with the romantic soul of a noble rebel, a Lord Byron torn between some meaningful extremes and forcibly alternating between them. On a quiet day—all of a sudden—thunderstorm blasts. One state, or kind, or attitude, is quickly replaced with another, and not necessarily the exact opposite. Melancholy is overtaken by rage in a matter of seconds—well, how do you think those duels used to happen so much in the past, back when people were much braver than the modern corporate plankton?

By now, you should have already figured my main point. If not, ChatGPT will help you per below (posting it unedited):

… such visceral, swift confrontations are embedded metaphorically in the dash’s brevity and decisiveness. It rejects lengthy introductions or diplomatic pauses, thriving instead on immediacy.

This dramatization of sudden transitions explains why readers who prefer smooth textual progression might recoil at frequent interruptions by em dashes. A balanced, tranquil personality desires a controlled pace to information, not abrupt tonal jerks. The dash defies the gradual, meticulously prepared narrative, embracing instead a rhetoric of spontaneous disruption. It appeals to those appreciative of dramatic rhythm and emotional intensity but risks alienating readers inclined toward measured coherence. In short, the em dash personifies narrative dynamism, charming precisely because it refuses the quiet conformity of traditional textual flow.

Why AI Loves It

Why do AI text-generators, especially ChatGPT, lean heavily on em dashes? One compelling explanation lies in the dash’s unmatched versatility in punctuating uncertainty, contrast, and nuance without syntactic rigidity. AI-generated text frequently grapples with balancing clarity, specificity, and linguistic flexibility. The dash’s inherent ambiguity suits a probabilistic language model brilliantly.

The em dash conveniently allows the AI to insert supplementary explanations, juxtapose differing ideas swiftly, or change narrative course mid-sentence without awkward transitions or overly formal connective phrases. Consider the alternative punctuation or grammatical structures available to express subtle or complex thoughts: these require precise hierarchical syntactic mastery. The dash sidesteps grammatical complexity, providing an economical yet powerful narrative pivot.

Furthermore, AI-generated responses, inherently ephemeral, benefit from punctuation reflecting spontaneity rather than deliberate calculation. Unlike structured prose composed by careful authors, AI models generate text incrementally, responding instantaneously to contextual cues without prior planning. The dash functions as the ideal punctuation for such fleeting, adaptive textual creatures—allowing them to simulate thoughtful hesitation or sudden insight without actual cognitive processing.

Additionally, the dash supports semantic openness. AI-generated text thrives on a nuanced presentation capable of ambiguity, adaptable enough to accommodate diverse interpretations. An em dash strategically placed implies multiple layers of meaning, a semantic richness accomplished with minimal textual adjustments. Such economy aligns precisely with the algorithmic goals of maximizing interpretative flexibility while minimizing linguistic redundancy.

Thus, ChatGPT’s supposed “obsessive” use of em dashes is not merely stylistic excess; it is algorithmic practicality meeting linguistic efficiency. The dash enables AI to mimic human-like thought processes convincingly, offering stylistic agility without compromising structural clarity.

Why Some Humans Hate It

Given these virtues, why do some writers harbor vehement dislike toward em dashes? This resistance stems from stylistic sensibilities prioritizing measured textual clarity and linear coherence. The dash, inherently interruptive, disrupts the predictable rhythm readers and writers accustomed to structured narrative prefer. This abruptness can feel intrusive rather than insightful.

Moreover, the frequency of dash usage by AI may threaten the aesthetic principles valued by certain professional writers. Copywriters, whose work emphasizes clarity, brevity, and disciplined transitions, naturally recoil from stylistic choices perceived as chaotic or arbitrary. AI-generated dashes appear unearned, their disruptive effects divorced from deliberate human intention. Consequently, frequent dashes become a symptom of linguistic artificiality, undermining professional textual authority.

Emotionally, readers accustomed to gradual narrative progression may resent the dash’s insistence on abrupt tonal shifts. Rather than perceiving these as sophisticated narrative tactics, they experience a jarring discontinuity, an uncomfortable linguistic jerk. Thus, hostility toward em dashes often masks deeper anxieties regarding textual coherence and professional identity.

Basically, if you’re annoyed by the em dash, it means you have a low tolerance for changes and are more likely to get hurt during the times like those we are experiencing right now. So, the reco to you is: embrace the em dash and what it represents fully: it’ll help you finally grow up and benefit from the imminent socioeconomic paradigm shift with a much higher likelihood of success.
