The Myth of the Rational Base: Le Bon and the Crowd Revisited

2–3 minutes

Gustave Le Bon’s The Crowd: A Study of the Popular Mind (1895) has had the half-life of uranium. His thesis is simple and disturbing: rational individuals become irrational when they merge into a crowd. The crowd hypnotises, contagion spreads, and reason dissolves in the swell of collective emotion.

It’s neat. It’s elegant. It’s also far too flattering.

Audio: NotebookLM podcast on this topic.

Le Bon assumes that the default state of the human being is rational, some Enlightenment holdover where citizens, left to their own devices, behave like tidy mini-Kants. Then, and only then, do they lose their reason in the mob. The trouble is that a century of behavioural science has made it painfully clear that “rational man” is a fairy tale.

Daniel Kahneman mapped our cognitive machinery in Thinking, Fast and Slow: System 1 (fast, intuitive, emotional) is running the show while System 2 (slow, deliberate, logical) is mostly hired as the PR manager after the fact. Dan Ariely built a career documenting just how predictably irrational we are – anchoring, framing, sunk-cost fallacies, you name it. Add in Tversky, Thaler, Gigerenzer, and the usual suspects, and the picture is clear: we don’t need a crowd to become irrational. We start irrational, and then the crowd amplifies it.

In that sense, Le Bon wasn’t wrong about crowds being dangerous, but he may have missed the darker point. A crowd doesn’t corrupt a rational base – it accelerates the irrational baseline. It’s not Jekyll turning into Hyde; it’s Hyde on a megaphone.

This matters because if you take Le Bon literally, the problem is situational: avoid crowds and you’ll preserve reason. But if you take Kahneman seriously, the problem is structural: crowds only reveal what was already there. The positive feedback loop of group psychology doesn’t replace rationality; it feeds on the biases, illusions, and shortcuts already baked into the individual mind.

Le Bon handed us the stage directions for mass manipulation. Modern behavioural economics shows us that the script was already written in our heads before we ever left the house. Put the two together and you have the perfect recipe for political spectacle, advertising, and algorithmic nudges.

Which makes Le Bon’s century-old observations correct – but not nearly bleak enough.

Language: Tool for Clarity or Shaper of Reality?

Pinker: The Optimist Who Thinks Language Works

Enter Steven Pinker, a cognitive scientist and eternal optimist about language. While we’ve been busy pointing out how language is a jumbled mess of misunderstandings, Pinker comes along with a sunny outlook, waving his banner for the language instinct. According to Pinker, language is an evolved tool – something that our brains are wired to use, and it’s good. Really good. So good, in fact, that it allowed us to build civilisations, exchange complex ideas, and, you know, not get eaten by sabre-toothed tigers.

Sounds like a nice break from all the linguistic doom and gloom, right? Pinker believes that language is a powerful cognitive skill, something we’ve developed to communicate thoughts and abstract ideas with remarkable precision. He points to the fact that we’re able to create entire worlds through language – novels, philosophies, legal systems, and scientific theories. Language is, to him, one of the greatest achievements of the human mind.

But here’s where things get a little sticky. Sure, Pinker’s optimism about language is refreshing, but he’s still not solving our core problem: meaning. Pinker may argue that language works wonderfully for most of our day-to-day communication – and in many cases, he’s right. We can all agree that saying, “Hey, don’t touch the flamey thing” is a pretty effective use of language. But once we start using words like ‘freedom’ or ‘justice’, things start to unravel again.

Take a sentence like ‘freedom is essential’. Great. Pinker might say this is a perfectly formed thought, conveyed using our finely tuned linguistic instincts. But the problem? Ask five people what ‘freedom’ means, and you’ll get five different answers. Sure, the grammar is flawless, and everyone understands the sentence structurally. But what they mean by ‘freedom’? That’s a whole other ball game.

Pinker’s language instinct theory helps explain how we learn language, but it doesn’t really account for how we use language to convey abstract, subjective ideas. He might tell us that language has evolved as an efficient way to communicate, but that doesn’t fix the problem of people using the same words to mean wildly different things. You can be the most eloquent speaker in the world, but if your definition of ‘freedom’ isn’t the same as mine, we’re still lost in translation.

And let’s not forget: while language is indeed a fantastic tool for sharing information and surviving in complex societies, it’s also great at creating conflicts. Wars have been fought over differences in how people interpret words like ‘justice’ or ‘rights’. Pinker might say we’ve evolved language to foster cooperation, but history suggests we’ve also used it to argue endlessly about things we can never quite agree on.

So, yes, Pinker’s right – language is a cognitive marvel, and it’s gotten us pretty far. But his optimism doesn’t quite stretch far enough to cover the fact that language, for all its brilliance, still leaves us stuck in a web of interpretation and miscommunication. It’s like having a state-of-the-art GPS that works perfectly – until you get to that roundabout and suddenly no one knows which exit to take.

In the end, Pinker’s got a point: language is one of the most sophisticated tools we’ve ever developed. It’s just a shame that when it comes to abstract concepts, we still can’t agree on which way’s north.

Sapir-Whorf: Language Shapes Reality – Or Does It?

Now it’s time for the Sapir-Whorf hypothesis to take the stage, where things get really interesting – or, depending on your perspective, slightly ridiculous. According to this theory, the language you speak actually shapes the way you see the world. Think of it as linguistic mind control: your perception of reality is limited by the words you have at your disposal. Speak the wrong language, and you might as well be living on another planet.

Sounds dramatic, right? Here’s the gist: Sapir and Whorf argued that the structure of a language affects how its speakers think and perceive the world. If you don’t have a word for something, you’re going to have a hard time thinking about that thing. Inuit languages, for example, are famous for having multiple words for different kinds of snow. If you’re an Inuit speaker, the hypothesis goes, you’re much more attuned to subtle differences in snow than someone who just calls it all ‘snow’.

Now, on the surface, this sounds kind of plausible. After all, we do think using language, don’t we? And there’s some truth to the idea that language can influence the way we categorise and describe the world. But here’s where Sapir-Whorf starts to go off the deep end. According to the stronger version of this hypothesis, your entire reality is shaped and limited by your language. If you don’t have the word for “freedom” in your language, you can’t experience it. If your language doesn’t have a word for “blue,” well, guess what? You don’t see blue.

Let’s take a step back. This sounds like the kind of thing you’d hear at a dinner party from someone who’s just a little too impressed with their first year of linguistics classes. Sure, language can shape thought to a degree, but it doesn’t have a stranglehold on our perception of reality. We’re not prisoners of our own vocabulary. After all, you can still experience freedom, even if you’ve never heard the word. And you can certainly see blue, whether your language has a word for it or not.

In fact, the idea that you’re trapped by your language is a little insulting, when you think about it. Are we really saying that people who speak different languages are living in different realities? That a person who speaks Mandarin sees the world in a fundamentally different way than someone who speaks Spanish? Sure, there might be some subtle differences in how each language breaks down concepts, but we’re all still human. We’re all still sharing the same world, and no matter what language we speak, we still have the cognitive capacity to understand and experience things beyond the limits of our vocabulary.

Let’s also not forget that language is flexible. If you don’t have a word for something, you make one up. If you’re missing a concept, you borrow it from another language or invent a metaphor. The idea that language is some kind of mental prison ignores the fact that we’re constantly evolving our language to keep up with the way we see the world—not the other way around.

And here’s the real kicker: if Sapir and Whorf were right, and we’re all walking around in little linguistic bubbles, then how on earth have we managed to translate anything? How have entire philosophies, religious texts, and scientific theories made their way across cultures and languages for centuries? If language really was shaping our reality that strongly, translation would be impossible – or at least incredibly limited. But here we are, discussing concepts like ‘freedom’, ‘justice’, and ‘truth’ across languages, cultures, and centuries.

So while it’s fun to entertain the idea that your language shapes your reality, let’s not give it too much credit. Yes, language can influence how we think about certain things. But no, it doesn’t define the boundaries of our existence. We’re not all stuck in a linguistic matrix, waiting for the right word to set us free.

MBTI Defined

Full Disclosure: I don’t subscribe to pop psychology, pseudo-psychology, or psychology. But I repeat myself. Of course, that’s just what an INTP would say anyway. So predictable.

I was introduced to the MBTI (Myers-Briggs Type Indicator) in the late ’80s as an undergrad Psychology student and then in Organisational Behaviour classes. I read about the foundations in the ’90s when I read the works of Carl Jung’s, Archetypal psychology.

I take the test every few years, and I consistently come up as INT. The P and J flip now and again. The last test I took was a P. Some tests have added an A or T dimension. There are also sub-factors. I’ll get to those presently.

MBTI is a personality assessment tool designed to categorize individuals into one of 16 distinct personality types. Based on Carl Jung’s theory of psychological types, MBTI helps identify how people perceive the world and make decisions. Each personality type is derived from a combination of four dichotomies:

  1. Extraversion (E) vs. Introversion (I) – Describes where individuals prefer to focus their energy. Extraverts are outward-focused, gaining energy from interaction, while Introverts are inward-focused, drawing energy from solitude.
  2. Sensing (S) vs. Intuition (N) – Defines how people process information. Sensing types rely on concrete details and present realities, while Intuitive types focus on patterns, possibilities, and abstract thinking.
  3. Thinking (T) vs. Feeling (F) – Describes how decisions are made. Thinking types prioritise logic and objectivity, while Feeling types consider values and emotional impact.
  4. Judging (J) vs. Perceiving (P) – Describes lifestyle preferences. Judging types prefer structure and closure, whereas Perceiving types favour flexibility and keeping options open.

Cognitive Functions

Each type has a specific “cognitive function stack” that explains how these preferences play out in everyday life. These functions are divided into:

  • Dominant Function: The most natural and frequently used function.
  • Auxiliary Function: Supports the dominant function, offering balance.
  • Tertiary Function: Less developed but still important, often emerging later in life.
  • Inferior Function: The least developed function, which tends to show up awkwardly, especially under stress.

The eight cognitive functions are:

  1. Introverted Thinking (Ti) – Internal analysis and logic refinement.
  2. Extraverted Thinking (Te) – External organisation and efficiency.
  3. Introverted Feeling (Fi) – Personal values and internal authenticity.
  4. Extraverted Feeling (Fe) – Social harmony and emotional dynamics.
  5. Introverted Sensing (Si) – Recalling past experiences and valuing tradition.
  6. Extraverted Sensing (Se) – Engaging with the present moment and sensory details.
  7. Introverted Intuition (Ni) – Focusing on future possibilities and deep insights.
  8. Extraverted Intuition (Ne) – Exploring ideas and brainstorming possibilities.

Assertive (A) vs. Turbulent (T) Dimension

The A-T dimension adds a layer of emotional self-regulation to MBTI types. It describes how confident or self-critical individuals are in their decision-making and handling of stress.

Turbulent (T) types tend to be more self-critical, stress-prone, and driven by perfectionism and external validation.

Assertive (A) types are self-assured, less prone to stress, and comfortable with their decisions.

With this definition in place, I’ll save further commentary for a future post.

A New Decalogue

1–2 minutes

Bertrand Russell published a New York Times piece in 1951 outlining his own 10 commandments.

1: Do not feel absolutely certain of anything.

2: Do not think it worthwhile to produce belief by concealing evidence, for the evidence is sure to come to light.

3: Never try to discourage thinking, for you are sure to succeed.

4: When you meet with opposition, even if it should be from your husband or your children, endeavor to overcome it by argument and not by authority, for a victory dependent upon authority is unreal and illusory.

5: Have no respect for the authority of others, for there are always contrary authorities to be found.

6: Do not use power to suppress opinions you think pernicious, for if you do the opinions will suppress you.

7: Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric.

8: Find more pleasure in intelligent dissent than in passive agreement, for, if you value intelligence as you should, the former implies a deeper agreement than the latter.

9: Be scrupulously truthful, even when truth is inconvenient, for it is more inconvenient when you try to conceal it.

10. Do not feel envious of the happiness of those who live in a fool’s paradise, for only a fool will think that it is happiness.

Although I don’t agree with all of these, I won’t challenge them here. On balance, they are words to live by.
