For the past eight years, Adam Green, a neuroscientist at Georgetown University, has been at the forefront of a national research initiative investigating how high school students express their ideas in college application essays, particularly in relation to the rise of ChatGPT. In one extensive study involving over 370,000 student submissions, Green and his research team observed that after ChatGPT's introduction, essays displayed a noticeable increase in vibrant and varied language. However, the deeper creative insights appeared to diminish, as many essays embraced familiar themes. Remarkably, human evaluators rated these post-ChatGPT essays as possessing greater "creativity," despite the repetition in their content.
In another examination, the researchers found that essays composed by humans contained up to eight times more original ideas compared to those generated with A.I. assistance.
A different team also conducted a study contrasting short stories crafted by human writers with those enhanced by A.I. Similar to the findings in Green's research, stories developed with A.I. boasted richer vocabulary and were deemed more enjoyable by readers. Yet, they tended to follow more traditional and predictable storylines. Unique and unconventional ideas, often characterized by surprising characters or settings, were frequently sidelined when A.I. played a role in the writing process.
For the first time in history, we've witnessed the emergence of technology that can produce words independent of the thoughts they convey. When a chatbot generates text, it's simply predicting which word comes next based on patterns learned from extensive training data, without a true understanding of originality in the ideas being expressed.
In stark contrast, when teenagers write essays themselves, their work offers a window into their thoughts and personalities, reflecting their efforts to derive meaning from their experiences. The act of searching for words engages the brain regions responsible for linking various ideas. For instance, a student who writes, “I’ll always think of learning to swim when I see a kite flying,” demonstrates a unique connection to personal memories, which, until now, has been an indicator of genuine creative thought.
