We lose abilities whenever we farm out tasks to other people or machines. Because our brains have limited real estate, they actively lose facts and skills we no longer use, to make room for new facts and skills.
When AI frees up all the neurons that currently are busy at finding the right adjective or trope,
The primary question for educators is: What can and should education achieve for humans? Essays may or may not be part of the answer. Further, the challenges of evaluating student work when AI is available should not obscure the question.
But the product leaves invisible the tangled lines of inquiry, the false but interesting starts, the productive, beautiful chaos of thinking and writing made of things that at one point seemed relevant but turned out not to be. Those things are a mix of sand and gold. Amidst this chaos is epistemic progress.
Finally, when we outsource the task of finding words to express things, we lose all the kinds of mental activation that come from those searches. Words and ideas are laden with associations, reminders, emotional charges — a whole forest of connections to our past and future tasks, ideas, and relationships.
They lose whatever it is writing essays is meant to teach.
Some of the relevant cognitive science to draw on is related to active versus passive learning. Active learning — generating content yourself — helps retention
generating content yourself
This is the heart of Retrieval Practice
This is where I think it’s ultimately about the student’s learning goals when writing an essay. We as professors can communicate what we hope they get out of the writing process, and what we think would count as success. But, as with any assignment, the student can engage more or less actively with that process. AI may make it easier or more tempting to be passive learners, but I do think AI can equally make us more efficient active learners as well.
When students let AI do the thinking for them, they miss out on learning how to think better. What these students lose today is what past students lost by enlisting a friend, parent, or hired gun to do the work.
Even if the economic demand for human cognitive labor is dramatically diminished, we still want wise humans in charge.
This requires that at least some humans — and ideally all humans — maintain the intellectual skills needed to envision and realize a good future. In the decades to come, the need for clear thinking may be less technocratic and more democratic.
The objective of writing is not just the product but also the process. Students who exclusively use AI to write their essays lose the process of thinking. And that is, after all, what we’re trying to do: produce new knowledge. If the goal is thinking or producing new knowledge, then a human being is the only one who can do that.
Writing leads to thinking; it’s not an end product, it’s a process that stimulates thought.
