Are people on the Left more intelligent?

 Now there’s a provocative question, and the short answer is, No. Political leanings are more associated with personality traits than IQ, according to studies I’ve read about, though I’m no expert. Having said that, I raise this subject, because I think there’s a perception on both sides that there is, which is why people on the Right love to use the word, ‘elites’, to describe what they see as a distortion of reality on subjects like climate change, the COVID pandemic and just about anything they disagree with that involves a level of expertise that most of us don’t have.
 
We live in a world overflowing with information (of which, ironically, I am a contributor) and most, if not all of it, is imbibed through a political filter. On social media we live in echo-chambers, so that confirmation bias is unplugged from all conduits of dissent.
 
To provide a personal example, I watch panel discussions facilitated by The Australian Institute using Zoom, on topics like plastic-waste, whistleblower protection, Pacific nations relations, economics of inflation (all relatively recent topics). The titles alone have a Leftish flavour (though not all), and would be dismissed as ‘woke’ by many on the Right. They are a leftwing think tank, and the panellists are all academics or experts in their field. Whether you agree with them or not, they are well informed.
 
Of course, there are rightwing thinktanks as well; the most obvious in Australia being the Institute of Public Affairs (IPA) with the catchcry, The Voice for Freedom. The Australia Institute has its own catchcry, We Change Minds, which is somewhat optimistic given it appears to be always preaching to the choir. It should be pointed out that the IPA can also provide their own experts and research into individual topics.
 
I’ve never hidden my political leanings, and only have to look at my own family to appreciate that personality traits play a greater role than intelligence. I’m the political black sheep, yet we still socialise and exhibit mutual respect. The same with some of my neighbours, who have strong religious views, yet I count as friends.
 
It’s not a cliché that people of an artistic bent tend to be leftists. I think this is especially true in theatre, where many an eccentric personality took refuge, not to mention people with different sexual orientation to the norm. We are generally more open to new ideas and more tolerant of difference. Negative traits include a vulnerability to neurosis, even depression, and a lack of discipline or willingness to abide by rules.
 
One of the contentious points-of-view I hold is that people on the Left have a propensity for being ahead of their time. It’s why they are often called ‘progressives’, but usually only by history. In their own time, they could be called ratbags, radicals or nowadays, ‘elitist’. History tends to bear this out, and it’s why zeitgeist changes are often generational.
 
Recently, I’ve come across a couple of discussions on Russell (including a 1960 interview with him) and was surprised to learn how much we have in common, philosophically. Not only in regard to epistemology and science (which is another topic), but also ethics and morality. To quote from an article in Philosophy Now (Issue 158, Oct/Nov 2023) titled Russell’s Moral Quandary by David Berman (Professor Emiritus Fellow, Philosophy Department, Trinity College Dublin).
 
…our moral judgements [According to Russell] come from a combination of our nurture and education, but primarily from our feelings and their consequences. Hence they do not arise from any timeless non-natural absolutes [like God], for they are different in different times and places.
 
It’s the very last phrase that is relevant to this essay, though it needed to be put in context. Where I possibly depart from Russell is in the role of empathy, but that’s also another discussion.
 
Even more recently, I had a conversation with a mother of a son and daughter, aged 22 and 19 respectively, where she observed that her daughter was living in a different world to the one she grew up in, particularly when it came to gender roles and expectations. I imagine many would dismiss this as a manifestation of wokeism, but I welcome it. I’ve long argued that there should be more cross-generational conversation. I’ve seen this in my professional life (in engineering), where there is a natural synergy between myself and cleverer, younger people, because we are willing to learn from each other. It naturally mitigates against close-mindedness.
 
The Right are associated with 2 social phenomena that tend to define them. Firstly, they wish to maintain the status quo, even turn back the clock, to the point that they will find their own ‘evidence’ to counter proposed changes. This is not surprising, as it’s almost the definition of conservatism. But the second trait, for want of a better word, has become more evident and even dangerous in modern politics, both locally and overseas. It’s particularly virulent in America, and I’m talking about the propensity to oppose all alternative views to the point of self-defeatism. I know that extremists on the Left can be guilty as well, but there are personalities on the Right who thrive on division; who both cultivate and exploit it. The end result is often paralysis, as we’ve seen recently in America with the House Speaker debacle, and its close-encounter with a nationwide catastrophe.
 
There is a view held by many, including people who work in my profession, that the best way to achieve the most productive outcome is through competition. In theory, it sounds good, but in practice – and I’ve seen it many times – you end up with 2 parties in constant argument and opposition to each other. Even if there are more than 2, they tend to align into 2. What you get is decision-paralysis, delays, stalemate and a neverending blame-game. On the other hand, when parties co-operate and collaborate, you get the exact opposite. Is this a surprise? No.
 
From my experience, the best leaders in project management are the ones who can negotiate compromises and it’s the same in politics. The qualities are openness, tolerance and persuasive negotiation skills. I’ve seen it in action numerous times.
 
In a post I wrote on Plato, I talked about his philosopher-king idea, which is an ideal that could never work in practice. Nevertheless, one of the problems with democracy, as it’s practiced virtually everywhere, is that the most popular opinion on a particular topic is not necessarily the best informed. I can see a benefit in experts playing a greater role in determining policies. We saw this in Australia during the pandemic and I believe it worked, though not everyone agrees. Some argue that the economy suffered unnecessarily. But this was a worldwide experiment, and we saw that where medical advice was ignored and fatalities arose accordingly, the economy suffered anyway.

On the philosophy of reality

 This follows on from my last post, after I saw a YouTube interview with Raymond Tallis on Closer to Truth. He’s all but saying that physics has lost the plot, or at least that’s my takeaway. I happen to know that he’s also writing a book on ‘reality’ – might even have finished it – which is why he can’t stop talking about it, and, it seems, neither can I.
 
I think there are 3 aspects to this discussion, even though they are not clearly delineated. Nevertheless, it might be worth watching the video to better appreciate what I’m talking about. While I agree with some of his points, I think Tallis’s main thrust that physicists contend that ‘reality dissolves’ is a strawman argument as I’ve never heard or read a physicist make that claim. Robert Lawrence Kuhn, who hosts all the talks on Closer To Truth, appears to get uncharacteristically flustered, but I suspect it’s because he intuitively thought the argument facile but couldn’t easily counter it. It would have been far more interesting and edifying if Tallis was debating with someone like Paul Davies, who is not only a physicist, but knows some philosophy.
 
At one point they get onto evolution, as Kuhn attempts to make the distinction between how we’ve evolved to understand the world but culturally moved beyond that. This leads to the 3 aspects I alluded to earlier.
 
The first aspect is that there is an objective reality independent of us, which we need to take seriously because it can kill us. As Tallis points out, this is what we’ve evolved to avoid, otherwise we wouldn’t be here. As I’ve pointed out many times, our brains create a model of that reality so we can interact with it. This is the second aspect, and is part of our evolutionary heritage.
 
The third aspect appears to be completely at odds with this and that appears to be what Tallis has an issue with. The third aspect is that we make mathematical models of reality, which seem, on the surface at least, to have no bearing on the reality that we experience. We don’t see wavefunctions of particles or twins aging at different rates when one goes on a journey somewhere.
 
It doesn’t help that different physicists attempt to give different accounts of what’s happening. For example, a lot of physicists believe that the wavefunction is just a useful mathematical fiction. Others believe that it carries on in another universe after the ‘observation’ or ‘measurement’. All acknowledge that we can’t explain exactly what happens, which is why it’s called the ‘measurement problem’.
 
What many people don’t tell you is that QM only makes predictions about events, which is why it deals in probabilities, and logically, observations require a time lapse, no matter how small, before it’s recorded, so it axiomatically happens in the past. As Paul Davies points out there is an irreversibility in time once the ‘observation’ has been made.
 
The very act of measurement breaks the time symmetry of quantum mechanics in a process sometimes described as the collapse of the wave function…. the rewind button is destroyed as soon as that measurement is made.
 
So, nothing ‘dissolves’, it’s just not observable until after the event, and the event could be a photon hitting a photo-sensitive surface or an isotope undergoing some form of radioactive decay or an electron hitting a screen and emitting light. Even Sabine Hossenfleder (in one of her videos) points out that the multiple paths of Feynman’s ‘sum-over-histories path-integral’ are in the future of the measurement that they predict via calculation.
 
Tallis apparently thinks that QM infers that there is nothing solid in the world, yet it was Freeman Dyson, in collaboration with Andrew Leonard, who used Wolfgang Pauli’s Exclusion Principle to demonstrate why solid objects don’t meld into each other. Dyson acknowledged that ‘the proof was extraordinarily complicated, difficult and opaque’, which might explain why it took so long for someone to calculate it (1967).
 
Humans are unique within the animal kingdom in that we’ve developed tools that allow us to ‘sense’ phenomena that can’t be detected through our biological senses. It’s this very attribute that has led to the discipline of science, and in the last century it has taken giant strides beyond anything our predecessors could have imagined. Not only have we learned that we live in a galaxy that is one among trillions and that the Universe is roughly 14 billion years old, but we can ‘sense’ radiation only 380,000 years after its birth. Who would have thought? At the other end of the scale, we’ve built a giant underground synchrotron that ‘senses’ the smallest known particle in nature, called quarks. They are sub-sub-atomic.
 
But, in conjunction with these miracle technologies, we have discovered, or developed (a combination of both), mathematical tools that allow us to describe these phenomena. In fact, as Richard Feynman pointed out, mathematics is the only language in which ‘nature speaks’. It’s like the mathematical models are another tool in addition to the technological ones that extend our natural senses.
 
Having said that, sometimes these mathematical models don’t actually reflect the real world. A good example is Ptolemy’s model of the solar system using epicycles, that had Earth at its centre. A possible modern example is String Theory, which predicts up to 10 spatial dimensions when we are only aware of 3.
 
Sabine Hossenfelder (already mentioned) wrote a book called Lost in Math, where she challenges this paradigm. I think that this is where Tallis is coming from, though he doesn’t specifically say so. He mentions a wavefunction (in passing), and I’ve already pointed out that some physicists see it as a convenient and useful mathematical fiction. One is Viktor T Toth (on Quora) who says:
 
The mathematical fiction of wavefunction collapse was “invented” to deal with the inconvenient fact that otherwise, we’d have to accept what the equations tell us, namely that quantum mechanics is nonlocal (as per Bell’s theorem)…
 
But it’s this very ‘wavefunction collapse’ that Davies was referring to when he pointed out that it ‘destroys the rewind button’. Toth has a different perspective:
 
As others pointed out, wavefunction collapse is, first and foremost, a mathematical abstraction, not a physical process. If it were a physical process, it would be even weirder. Rather than subdividing spacetime with an arbitrarily chosen hypersurface called “now” into a “before observation” and an “after observation” half, connected by the non-unitary transformation of the “collapse”, wavefunction collapse basically implies throwing away the entire universe, replacing it with a different one (past, present, and future included) containing the collapsed wavefunction instead of the original.
 
Most likely, it’s expositions like this that make Tallis throw up his hands (figuratively speaking), even though I expect he’s never read anything by Toth. Just to address Toth’s remark, I would contend that the ‘arbitrarily chosen hypersurface called “now”’ is actually the edge in time of the entire universe. A conundrum that is rarely acknowledged, let alone addressed, is that the Universe appears to have no edge in space while having an edge in time. Notice how different his ‘visualisation’ is to Davies’, yet both of them are highly qualified and respected physicists.
 
So, while there are philosophical differences among physicists, one can possibly empathise with the frustrations of a self-identified philosopher. (Tallis’s professional background is in neuroscience.)
 
Nevertheless, Tallis uses quantum mechanics just like the rest of us, because all electronic devices are dependent on it, and we all exploit Einstein’s relativity theories when we use our smartphones to tell us where we are.
 
So the mathematical models, by and large, work. And they work so well, that we don’t need to know anything about them, in the same way you don’t need to know anything about all the technology your car uses in order for you to drive it.
 
Tallis, like many philosophers, sees mathematics as a consequence of our ability to measure things, which we then turn into equations that conveniently describe natural phenomena. But the history of Western science reveals a different story, where highly abstract mathematical discoveries later provide an epistemological key to our comprehension of the most esoteric natural phenomena. The wavefunction is a good example: using an unexpected mathematical relationship discovered by Euler in the 1700s, it encapsulates in one formula (Shrodinger’s), superposition, entanglement and Heisenberg’s Uncertainty Principle. So it may just be a mathematical abstraction, yet it describes the most enigmatic features discovered in the natural world thus far.
 
From what I read and watch (on YouTube), I don’t think you can do theoretical physics without doing philosophy. Philosophy (specifically, epistemology) looks at questions that don’t have answers using our current bank of knowledge. Examples include the multiverse, determinism and free will. Philosophers with a limited knowledge of physics (and that includes me) are not in the same position as practicing physicists to address questions about reality. This puts Tallis at a disadvantage. Physicists can’t agree on topics like the multiverse, superdeterminism, free will or the anthropic principle, yet often hold strong views regardless.
 
I’m always reminded of John Wheeler’s metaphor of science as an island of knowledge in a sea of ignorance, with the shoreline being philosophy. Note that as the island expands so does the shoreline of our ignorance.
