This year, I started lifting heavy weights.
After falling out of the habit of weight training, it feels good to pick up my weights and challenge my body.
At a time of increasing uncertainty, this simple practice helps me to feel strong and powerful. As Professor BJ Fogg says:
“When you feel physically stronger, this feeling ripples out into many other areas of life.”
My muscles were growing, but one part of my body was slowly getting weaker.
What part am I talking about?
I’m talking about my brain, specifically my ability for deep learning and thinking.
A couple of months ago, it dawned on me that my brain had seen better days. When I confided in my husband about this, he said he felt the same way about his brain.
But it wasn’t always like this.
When I was a university student, it was normal to spend several hours each day reading and mind mapping.
Most days, I’d feel confused about a new concept or how one idea was connected to another. I didn’t know the answers to a lot of questions.
But I sat with the discomfort, knowing it was a normal part of the learning process.
By the time I submitted my PhD thesis (nearly 10 years ago), I was at the peak of my mental fitness. My brain was sharp and strong.
These days, it feels much harder to think and learn. Too often, I notice that I’m impatient like a toddler. I want the answers quickly.
What’s changed in the last 10 years?
While learning has never been easy for me, deep learning felt easier 10 years ago because:
- I had a basic flip phone that could only make calls and send texts (I resisted getting a smartphone for as long as possible).
- I had lots of time and space to learn.
- I was surrounded by other people who were constantly learning (other PhD students and academics).
Contrast those conditions to the modern environment most of us find ourselves in today:
- We carry smartphones in our pockets containing addictive social media apps that hijack our attention.
- This tech leaves us feeling increasingly isolated and disconnected from one another.
- Many of us have been repeatedly infected with an airborne virus (COVID-19) that has been shown to cause cognitive impairment and damage to our immune systems.
- Then there’s the new kid on the block: generative AI. Instead of being used as a study tool, generative AI is doing the work for us.
If you wanted to create a recipe to diminish a person’s ability to learn and think deeply, those would be the perfect ingredients.
Students today find themselves in an environment that actively works against deep learning. In this environment, we are pushed to learn in superficial ways, if at all.
A recent Guardian piece explored how AI is having a negative impact on students’ ability to study. Survey research conducted in the UK found a staggering 62 per cent of students agreed with the statement, “It’s too easy to find the answers without doing the work myself.”
Only 2 per cent of students said they did not use AI.
AI has become a crutch for many people
As humans, we tend to live for the short-term. Thinking about the future and long-term planning are not strengths for most of us, especially teenagers whose brains are still developing.
Now, imagine you’re a young person who finds high school incredibly boring. You’re a little insecure, and you lack confidence in your ability to learn. To make matters worse, you can’t see the point of your subjects and how what you’re learning is going to help you later in life.
Suddenly, a free tool appears in your world that can help you avoid the pain, suffering, and potential humiliation of failure with your school subjects. It can also save you a lot of time.
This tool effortlessly pumps out an essay within seconds when it would take you many hours to write.
Would you be able to resist using this tool?
I’m almost certain I wouldn’t have been able to as a young person.
ChatGPT is like candy. It’s hard to resist. But resist we must because too much is at stake, especially for young people.
Resisting the temptation of AI
Many people I respect and admire speak enthusiastically about generative AI. There’s this palpable sense that if you don’t get on board the AI train, you’re going to be left behind.
But not everyone thinks this way.
A number of people, including Tristan Harris and Aza Raskin from the Center for Humane Technology, argue that those who become too dependent on AI for support and validation may suffer in the long run.
The use of AI is resulting in unbuilt skills remaining that way and already built skills diminishing.
For example, a group of researchers from MIT recently released a working paper called Your Brain on ChatGPT. This study took 54 students and asked them to perform a specific task over four sessions: writing an essay.
The students were split into three groups:
- LLM (large language model) group: They were allowed to use ChatGPT to write their essays
- Search engine group: They could use a search engine to write their essays
- Brain-only group: They had to rely on their brains to write their essays
The researchers examined students’ brain activity as they worked on their essays to assess cognitive engagement and cognitive load. They found that the brain-only group had higher levels of neural connectivity, which was associated with stronger memory and firmer ownership of the written work.
The researchers stated in the discussion section of their working paper:
“[AI tools] may unintentionally hinder deep cognitive processing, retention and authentic engagement with written material. If users rely heavily on AI tools, they may achieve superficial fluency but fail to internalize the knowledge or feel a sense of ownership over it.”
The researchers did something really interesting in the fourth and final essay writing session: they switched the groups.
The students in the brain-only group could now use ChatGPT to write their essays and the LLM group had to rely on their brains (no more ChatGPT for them).
How did each group do?
The brain-only group performed better when using ChatGPT. These students had already engaged with the ideas more deeply and therefore seemed able to critically examine the information ChatGPT brought up.
In contrast, the LLM group struggled when it came to just using their brains after using AI to write their essays for the first three sessions.
The lead researcher of this study, Dr Nataliya Kosmyna, summed it up nicely when she said in a TV interview, “Use your brain”.
What I take from this working paper is that if you want to have a deeper learning experience and create more original work, it’s best to avoid using generative AI. But if you must use AI, hold off on using it in the early stages of a writing project.
Freeing yourself from AI dependence
If you feel like you’ve become dependent on AI, it’s not too late to turn things around.
The human brain is incredibly resilient. You can learn to work differently. You can learn how to learn.
In the book The Disengaged Teen, Jenny Anderson and Rebecca Winthrop state:
“More than ever before, what kids need now is to become better at learning. Generative artificial intelligence (AI) is accelerating rapidly, and everyone agrees that the pace of change will continue to be dizzying. Uncertainty is the new norm. No one knows exactly what shifts in jobs and society are in store. What can best protect and prepare our kids? Rose Luckin, a British professor and AI expert is blunt: Make them “good at learning.” The only thing that can insulate them from rapid change and give them the confidence to move forward is the ability to learn and adapt.”
It’s not too late to reclaim your cognitive power. But you’ll have to push your brain to the point of discomfort without using AI.
Just like you can’t build muscle by getting an exoskeleton to lift heavy weights for you, you’ll have to do the work and resist the temptation to outsource tasks to generative AI. But it’s important to get clear on why you want to build cognitive power and resist the allure of AI.
My reasons for building cognitive power and resisting AI
When a man I used to train at the gym with told me he was using AI to write his blog posts, my first thought was, “Why would you want to do that?”
I refuse to use generative AI to write any of my blogs. Why? Because for the most part, I get a lot of satisfaction from writing.
Yes, it can be frustrating and painful to write.
Yes, I usually always feel awkward and clumsy as I put pen to paper or fingers to keyboard.
Yes, it can take a lot of time to write an article.
But writing is a form of thinking. It helps me to make sense of the world. It also gives me a sense of purpose.
When I put a piece of my own writing out into the world, I feel good about it. I wrestled with ideas and, as a result, learnt something new.
If I offload all of my work to ChatGPT, I’ve robbed myself of a valuable opportunity to think, learn, and grow.
As Dr Nancy Colier states in her book The Power of Off:
“We are conditioned to believe that easier means better, that the less we have to do, the happier we will be. But often this is not in line with people’s actual experiences. We feel good when we are productive and engaged, which requires effort.”
To sum up
It’s only natural to be amazed by the things AI can do. But it’s also important to be fully aware of what this technology has the potential to do to our brains, relationships, and the quality of our lives.
Based on the research I’ve read so far, I’m not convinced this technology is good for young people to use. It’s too easy to become dependent on using generative AI, to fall for its hallucinations, and for cognitive skills to atrophy or not develop at all. Let’s also not forget how energy-intensive all those data centres are.
This is why I’m resisting using generative AI as much as possible.
If you care about your brain, people, the health of the planet, and all the things that make life rich and wonderful, stop and think twice before turning to an AI chatbot. Be brave: use your brain and trust your thinking.
