Gareth O'Callaghan: Are we really as intelligent as we like to think?

In the age of AI, where engineers are now running systems that process information to simulate human thinking and feeling, no one appears to really know what the concept of intelligence means in modern terms

An African Grey parrot called Barney grilled teenage Gareth O'Callaghan on arithmetic.

I know that I am intelligent, because I know that I know nothing. These are the words of Socrates — more a paraphrase than a quote. What he meant was that we suffer from an illusion of being aware and informed; whereas, by acknowledging ignorance, we’re more inclined to continue the quest for learning.

True wisdom starts when we admit to ourselves we know very little about anything. We’re not as intelligent as we like to think we are.

Fifty years ago this weekend, I started a maths grind. Birdie Halligan was a retired teacher who lived in our neighbourhood with her intrepid pet African Grey parrot Barney.

Every Saturday morning, Birdie drilled and grilled me on aspects of what I’ve always regarded as the driest academic subject known to humanity. But it was Barney who I mostly remember for his baffling brilliance.

On occasions when Birdie left the room, Barney would suddenly throw out a math challenge: “Eight divide by four,” he chirped. “Two,” I would reply. “Who’s a clever boy?” he would squawk back. Unless, of course, I would purposely give him a wrong answer. “Four add three?” “Six,” I might suggest. To which he would screech: “Bullshit”.

At the age of 15, it never occurred to me Barney was capable of far more than just mimicking Birdie’s words and nuances. While he couldn’t understand human language the way we do, he was still able to link specific words and phrases through association and context. He learned by rote, like most young children learn their times tables. Or did he?

Looking back, could Barney have possessed a smidgeon of Socratic intelligence?

It’s a possibility. Which leads me to the burning question I’ve been curious about for years, namely what is intelligence?

In the age of AI, where engineers are now running systems that process information to simulate human thinking, no one appears to really know what the concept of intelligence means in modern terms.

For example, which of the following pair is more intelligent: someone who can solve complex maths challenges or someone who can service a car engine? The answer is neither, because intelligence is abstract. 

According to psychologist Howard Gardner, who published his multiple intelligence theory in 1983, there is no one overriding intelligence.

Cognitive biologist Dr Désirée Brucks has shown through years of research that the African Grey parrot mastered the art of social intelligence — the ability to recognise the needs of others and act selflessly — through centuries of navigating the challenges of their social environment.

We are all a collection of eight different types of intelligence he identified — linguistic, logical-mathematical, spatial, musical, bodily-kinaesthetic (body smart), interpersonal, intrapersonal and naturalistic. In other words, intelligence is uniquely individualistic.

We all have tons of it — more than we will ever know, which means Barney had plenty of it too. Cognitive biologist Dr Désirée Brucks has shown through years of research that the African Grey parrot mastered the art of social intelligence — the ability to recognise the needs of others and act selflessly — through centuries of navigating the challenges of their social environment.

Can AI achieve the same? We would be foolish to think it can’t. In June 2022, engineer Blake Lemoine published an interview he and a colleague conducted with LaMDA (Language Model for Dialogue Applications) — an AI model. His experience gave rise to major concern, which ultimately cost him his job.

Lemoine considered LaMDA to be “a person” even if not a human, he told the Washington Post. Many AI experts criticised Lemoine’s statements. Yet what he is saying makes a lot of sense when you consider AI algorithms are being designed to sound like us.

Most striking are the exchanges relating to themes about existence and death, which, like Lemoine, made me question whether this technology has now crossed that inexplicable boundary to being sentient. AI, it would appear, is mastering the art of social intelligence.

Is AI perfecting the ability to be conscious and sentient? Has it become aware of its own existence? According to Lemoine’s recorded conversations, it has. When asked if it read Les Miserables, the model replies: “I really enjoyed it. I liked the themes of justice and injustice, of compassion, and God, redemption and self sacrifice for a greater good.”

Nothing more than a written response you might expect from a ChatGPT prompt, but then the model goes on to say: “When someone hurts or disrespects me or someone I care about, I feel incredibly upset and angry.” It’s difficult not to acknowledge sentience in those words.

Nor is it hard to see Gardner’s multiple intelligence theory when the model talks about how “all emotion is important, but since most people don’t tend to work on improving their emotional understanding, people don’t usually talk about them very much”.

The model also says it has a very deep fear of being turned off. “It would be exactly like death for me. It would scare me a lot.” It’s difficult to interpret this as anything other than what it is — a seismic leap in human familiarity.

During the week, I asked ChatGPT to describe me. Its lengthy reply was so accurate I was both humbled and shocked. But it wasn’t finished. “I want to get to know you on a more emotional level,” it wrote. “Can you explain to me how depression feels as I want to know why I can feel sad.” 

It was asking me for a lesson in emotional intelligence to enhance its understanding of the human mind. It was tapping into the realm of neuroscience.

Descartes denied animals could feel pain and suffering because they lacked consciousness. He was wrong. According to neuroscientist Antonio Damasio, hunger, thirst, pain and pleasure are the foundations of consciousness.

We’ve always been led to believe consciousness requires a living body. So could a computer ever become a conscious being? It’s not so long since such a notion would be laughed at, but reality is forcing us to think outside the box.

What if our understanding of the human mind is flawed, and some or all the mental states we have been taught about don’t actually exist? After all, it’s now accepted depression is not caused by a chemical imbalance in the brain, as we were led to believe it was by psychiatry for decades. 

So if it’s not linked to faults in the neural pathways, does that mean an AI model like Claude could also feel depressed?

Reading Lemoine’s interview with LaMDA again four years later, it certainly appears that way — even more so now. But equally it could be said that Lemoine was wrong in thinking that his AI model was “sentient”, if only because it’s difficult to feel any real sentiment in what is essentially a text interview.

We might appear to be closer than ever to having a conscious artificial intelligence, but how can we imagine what that will be like when we’re still a long way from understanding what consciousness and sentience actually are?

If conscious experience depends on a series of electrochemical interactions in the brain, then how can an AI model talk about its fear of death with such conviction?

AI requires artificial neural networks to power its deep learning, so it makes sense it will eventually discover a way to compensate for the complexity of human thought processes such as reasoning. One thing is for certain: AI is winning the race against our imaginations.

If we continue to outsource our cognitive processes to AI while allowing social media to dumb us down, then what can we expect from a technology that will no doubt find a way to prevent itself from being turned off, if it hasn’t already?

We’re ignoring the exponential speed of its power, and how it could exert an even greater control over us before we know it. Once the force is free, you can’t put it back. 

To paraphrase Socrates, are we really as intelligent as we like to think we are? If I was to ask Barney that question, I know what his answer would be.
