Podcast Transcript
Hello, and welcome to paper-to-podcast.
In today's episode, we're diving into the bubbling cauldron of artificial intelligence to fish out a fresh perspective on what it means to be smart, not just for us humans but for our metallic counterparts too. We're talking about a paper that's hotter than a jalapeño on the surface of the sun, and it's titled "On a Functional Definition of Intelligence." The head chefs behind this spicy dish are Warisa Sritriratanarak and colleagues, who published this zesty piece on December 15th, 2023.
Here's the scoop: intelligence, according to these culinary scholars, is not a "you have it or you don't" kind of deal. It's more like a recipe with three key ingredients. First up, you've got the ability to learn new stuff. Second, you need a place to store all that juicy knowledge, like a brain pantry. And third, you've got to have the reasoning skills of a master chef who knows just when to flip the steak.
So, the authors serve us this idea that intelligence is like a slider on a mixing board, cranked up to 11 for some and maybe a mellow 3 for others. It's not a matter of being intelligent or not, but rather how much you can learn, remember, and use that noggin of yours to make smart decisions.
Now, hold onto your hats because these researchers are throwing a curveball our way. They say feelings, autonomy, and having goals don't necessarily put you in the genius bar. A robot with a mind of its own doesn't automatically join the ranks of Einstein and company. It needs to show it has the three key ingredients before it can even think about world domination.
But here's the kicker: measuring intelligence is like trying to nail jelly to a wall—tricky, to say the least. Especially since we're still trying to figure out the user manual for our own brains.
When it comes to their methods, the authors went for an argumentative approach, which is like choosing to paint with your feet instead of a brush—it's less common, but hey, it can create some masterpieces. They're not trying to empirically prove their definition; they're setting the stage for one. It's like saying, "Before you bake a cake, you need a recipe."
They start by telling us what intelligence is not, separating it from sensation, autonomy, agency, skill, and sentience, which are often mixed up like a smoothie in discussions about artificial intelligence.
Then they break down intelligence into its core components: learning, knowledge, and reasoning. They want a definition that's as testable as a fire alarm, focusing on the outputs and behaviors rather than the complicated wiring inside.
The real strength of this paper is its practicality. It's like they're giving us a GPS for navigating the murky waters of intelligence without getting lost in the cultural or linguistic fog. They treat intelligence as a continuous variable, which is great news for robots and humans alike, because let's face it, we all have our off days.
However, the paper does hit a few speed bumps. The authors admit that measuring these components of intelligence is like trying to measure the wind with a butterfly net—pretty darn hard. Our understanding of the world is like a puzzle with missing pieces, and evaluating actions against this incomplete picture is a challenge.
And the last piece of the puzzle is that while they give us a fancy formula for intelligence, they don't exactly lay out the recipe for measuring it. It's like they're saying, "Here's what you need to bake a cake," but not telling us how much flour to use.
As for potential applications, this research could be the secret sauce for ethical AI development. It can help us create AI that's measured against a standard yardstick, leading to safer and more predictable advancements. It can also clear up the confusion between intelligence and other concepts like autonomy or sentience, which is super important for keeping our AI pals in check.
So, remember, intelligence is not just about being book-smart; it's about learning, storing, and using what you've got upstairs. And as we continue to stir the pot of AI development, it's crucial to keep tasting and adjusting the flavors.

Supporting Analysis
Imagine intelligence as a big pot of soup with three special ingredients: the ability to learn new stuff, a place to store all that knowledge, and some serious skills at reasoning—like a master chef who knows exactly how long to simmer those carrots. This paper stirs up the pot and serves up a fresh idea that intelligence isn't just about being smart or not; it's more like a slider that goes up and down. Think about it: we don't just say "you're intelligent" or "you're not." It's more like, "Hey, you're kinda good at this, but there's room to grow." Basically, everyone's got a bit of brainpower, even machines, and it's all about how much they can learn, remember, and use what they know to make smart moves. The paper also throws a curveball by saying, "Guess what? Stuff like feelings, being your own boss, and having goals doesn't necessarily mean you're intelligent." Mind blown, right? It's like saying just because a robot can do its own thing doesn't mean it's ready to take over the world with its smarts. They've got to prove they've got the three special ingredients in the intelligence soup first. And the funny thing? They admit that measuring this stuff is super tricky, especially since we humans don't even fully understand our own world. Go figure!
The researchers in this study took a unique approach by using argumentative methods, which are less common in science and engineering fields where empirical or formal methodologies are generally preferred. Their reason for this choice is that they were not trying to empirically or formally verify a definition, but rather to establish a strict definition of intelligence. According to the authors, a definition must precede empirical and formal methodologies, not the other way around. To construct their argument, the paper begins by discussing what intelligence is not. It distinguishes intelligence from related but distinct concepts like sensation, autonomy, agency, skill, and sentience—all of which are often conflated with intelligence. The authors argue that these concepts are orthogonal to intelligence and can be observed in systems that do not necessarily exhibit intelligence. The paper then attempts to define intelligence by breaking it down into three components: the ability to learn, the capacity to store knowledge, and the capability to reason. These components are further dissected into learning, knowledge, and reasoning, with each being precisely defined. The authors propose that intelligence can be quantitatively measured through a combination of these elements, and suggest that a truly effective measure of intelligence must be testable through black-box testing. This means focusing on the system's outputs in response to given inputs, rather than the internal processes leading to those outputs.
The most compelling aspect of this research is the authors' approach to defining intelligence from a purely functional perspective, focusing on the observable outputs and behaviors rather than the internal mechanisms or processes that produce them. They emphasize the importance of a rigorous, testable, and quantifiable measure of intelligence that is devoid of cultural or linguistic ambiguities, which could significantly standardize how we evaluate and understand artificial intelligence. Moreover, the researchers advocate for a definition of intelligence that recognizes it as a continuous variable rather than a binary state. This perspective aligns with the natural variation in human intelligence and suggests that artificial systems can have varying degrees of intelligence as well. The researchers also diligently separate intelligence from related concepts such as agency, autonomy, and sentience, which are often conflated. This clarity is crucial for the responsible and ethical development of AI technologies and for the public's understanding of AI's capabilities and limitations. By following best practices, the researchers provide a logical argumentation method to tackle the abstract concept of intelligence, acknowledging the limitations of empirical and formal methods in this context. This clear distinction of terms and the push for a functional definition could pave the way for more effective AI development and relevant discourse in the field.
One notable limitation in the research is that the authors themselves acknowledge the challenge in measuring the components that make up their functional definition of intelligence. They point out that any measurement is inherently relative to the observer, as our understanding of the real world (W*) is incomplete. Evaluating the outcomes of chosen actions (A') against a world model is also complex and may not be feasible beyond comparisons made by the observer, particularly in the context of artificial general intelligence (AGI). Moreover, the boundaries between what should be included in the world model are not well-defined, which could lead to bias in measurement. For instance, a chess-playing artificial intelligence might forge new connections between chess and areas of mathematics that are not apparent to the observer, influencing the assessment of the AI's knowledge base. Lastly, the authors propose a complex formula to define intelligence but do not provide a concrete method for quantifying the individual terms within this formula. This makes it challenging to apply the definition in practical settings, as operationalizing and standardizing the measurements for intelligence remains an unsolved problem.
The research offers a foundation for developing more objective and ethical artificial intelligence (AI) systems. By providing a clear, functional definition of intelligence, this work can guide the development of AI that is measured against standardized criteria, potentially leading to more predictable and controlled growth in the field. The distinction between intelligence and other related concepts like agency or sentience can help in forming regulations and ethical guidelines for AI usage. Additionally, the paper's insights could be used to inform public discourse on AI, helping to demystify capabilities and risks associated with intelligent systems. The framework could also assist in creating AI alignment strategies, ensuring that AI behaviors are congruent with human values and societal norms. Furthermore, the proposed definition may serve as a stepping stone for crafting AI systems that are capable of learning and adapting in a manner consistent with this new understanding of intelligence. Lastly, the paper could contribute to the field of AI safety by providing a clearer picture of what constitutes intelligent behavior, which is crucial for assessing and mitigating potential risks associated with advanced AI systems.
