Why ChatGPT loves em dashes — and how to type them on Windows 11

You might have noticed a punctuation mark called an em dash when using ChatGPT or reading AI-generated text. Although this mark isn’t recent, its frequent use in AI-written text has made it more noticeable on social media and daily writing platforms.

If you’ve either been a longtime fan of the em dash or recently discovered this punctuation mark, you might consider incorporating it into your writing. However, you won’t find an em dash directly on your keyboard. But don’t worry, the em dash is readily accessible on Windows 11; you simply need to know where to find it.

What is an em dash?

The em dash, resembling an extended hyphen, serves as a flexible punctuation symbol. It can stand in for commas, colons, or even parentheses in certain contexts.

Merriam-Webster devotes a whole webpage to the em dash, offering guidance on its usage and sharing interesting tidbits. For instance, you might be surprised to learn that the term “em dash” comes from it having the same breadth as a capital ‘M’.

Instead of frequently inserting details within parentheses in the midst of your sentences, consider utilizing a set of em dashes as an alternative. Intriguingly, these em dashes can also be employed to initiate a list, making them quite versatile in their application!

There are, however, several ways to input an em dash on Windows 11.

Why does ChatGPT love em dashes?

Using an em dash is particularly appealing for AI because of its versatility – it can take on the roles usually filled by commas, colons, or even parentheses. This makes it a very adaptable and useful tool in writing.

It appears that ChatGPT and other Large Language Models (LLMs) have a preference for using the em dash more than human writers do. However, it’s important to note that the em dash isn’t something these models invented; instead, it has been in use for hundreds of years and can be found in many classic works. It’s likely that the abundance of this punctuation mark in their training data is why they recognize and employ it as frequently as they do.

It’s not accurate to automatically think that an email with an em dash was written by ChatGPT, but its frequent appearance could serve as a warning sign. If someone you know well has suddenly started using em dashes after the launch of ChatGPT, it might be prudent to scrutinize their writing more closely – provided that employing ChatGPT in such a situation is considered unfavorable.
