The Slippery Slope fallacy: the one we’ve never got on with

“Don’t throw that rubbish there! Put it in the bin like you’re supposed to!” Many years ago we lived on a pleasant private estate in West London with trimmed lawns, walkways, security, a residents association, all those sorts of things. The only problem was some of the residents, who were either too lazy or felt culturally compelled to throw their domestic rubbish down by the rubbish chutes instead of putting in properly, as we, the decent majority did. This bad practice spread, being quickly copied across the estate and soon we all had a widespread problem with flies, rodents and an ugly disfigurement of our pristine areas. It’s called the slippery slope. Another example is when the office agrees to step out for a single drink and, three hours later, the entire company ends up blind drunk ,broke and embracing each other with varying declarations of love. Everyone copies bad behaviour, because they feel entitled, or are missing out. And so crime, disorder, drugs and violence spread quickly through communities, reducing everyone to common beggary.

And that raises a bigger problem for us here at LSS. For years we have proudly touted our Enlightenment, Whig, rational, call them what you will credentials like a badge of honour. Central to our purpose, hardened readers will recall, is the practice of reason and logic. Avidly do we follow websites like your logical fallacy which are stuffed with every classic example you could wish for: post hoc propter hoc, texas sharpshooter, all shining beacons of clear thought each one of them.. Standing out like a dead rat in a melon souffle is the slippery slope, of which the authors state

Allowing to happen will cause Z to happen: therefore we should ban A now!

Yes, we see the error. The slippery slope is a fallacy for it allows one to jump to conclusions without checking each intervening link from A to Z for both logic and empirical fact. Its the classic howler of someone like a Daily Mail columnist, carried away on tides of hysteria and dread. The trouble is: it’s how humans really behave. It’s the way most of them are.

So our problem with the slippery slope mirrors a more general problem. Reason, learning, and all the the qualities which we prize are not always good guides to how society works. (Try a Friday night out in Croydon if you don’t believe us) Yet the values we espouse are the only ones which will ensure not only the good life but also human survival in the long term. The problem we now have is how do we form a critical mass to allow those values to prevail?

How life evolved long ago is absolutely relevant today

Long suffering readers of this blog will recall our occasional sallies into the remote past. Like some latter day Doug McClure we occasionally take you into a world stuffed with dinosaurs, ape men and pterodactyls, to the detriment of more relevant stuff on antibiotics or the US Ten Year Bond. And so, although we were privately raving about this piece below called How did life get multicellular? from Nature Briefing, we thought we ‘d spare you from our private obsessions about things that took place between 800 -600 million years ago.

Until a chance encounter with one of more intelligent friends in the car park at our Spanish Conversation group produced the most inspiring thought. “All those Choanoflagellates. protometazoans. Filasterea. whatever, have to do several things if they are to succeed in living together. To glue up to each other. To signal little messages. To co-ordinate the cycles of cell division. Just like cancer cells have to, in fact. And then it hit us. These funny little organisms are the perfect way to model the behaviour of cancer cells. Not just the molecular and genetic mechanisms, but also the Information and Complexity models we must build to understand them: a cancer cell is a typical metazoan cell gone wrong.

Which confirmed a very old principle of this blog. All research however abstruse it may seem, will have a pay off somewhere one day. If it doesn’t benefit the economy, it will make us live longer; sometimes it may do both. These researchers are not just having fun on the edge of time: they may be contributing directly to the study of a disease which will kill half of us. There’s a thought for anyone who wants to cut university budgets or meddle with the findings of scientists.

To play out we shall first post the Nature Briefing paragraph. If you can get past that we’ve some supporting evidence for our basic proposition. We hope both will inform

Across all forms of life, the move from being single-celled to multicellular seems to have happened dozens of times — for animals, though, the jump was one-and-done. The unique cocktail of environmental and genetic factors that helped animal ancestors make that jump still eludes our understanding. To investigate, researchers are focussing on unicellular organisms that ‘dabble’ in multicellularity, occasionally forming colonies of many cells. By studying these organisms as they flit between the two states, scientists are hoping to illuminate how multicellularity stuck in animals — and what sparked the single successful event that gave rise to the animal kingdom.Nature | 11 min read

ASTRACT BECOMES APPLIED

This work discusses how cancer disrupts the gene regulatory networks (GRNs) that evolved to coordinate multicellular life. These networks balance genes inherited from unicellular ancestors (handling basics like metabolism and division) with newer multicellular genes (handling coordination, differentiation, and tissue integrity). https://genomebiology.biomedcentral.com/articles/10.1186/s13059-024-03247-1

and this how somatic mutations in early metazoan genes specifically disrupt the regulatory links between unicellular and multicellular gene networks. The result? Tumours behave like rogue unicellular entities, ignoring the cooperative rules of multicellularity. Some of these disrupted genes even correlate with drug response, hinting at therapeutic relevance

Co-LAB-oration, or why its good news UK is back in Horizon

Science is good for economic growth. It’s theme we’ve touched on before in this blog(LSS 4 10 23; 1 3 24) So any initiative that builds on this incontrovertible fact will meet with our approval. if only because we want a higher standard of living next year. Which is why we showcase this article by Lisa O’Carroll of the Guardian [1] which reviews progress of the UK’s revived membership of the EU administered Horizon Programme, which tries to bring together the efforts of scientists technologists and scholars from across many countries.

It may soothe the objections of our more rabid eurosceptic readers, to learn that almost half the members (20:27) are not in the European Union, but are located as far afield as Canada and New Zealand (“is that Bri’ish Empoire enuff fer yer, Guv?”) But because science is a collaborative process it helps if you can recruit your teams from close neighbours, if only because it saves on things like travel costs on the day of the interview. We need not discourse long on close financial and technological links as Lisa covers them well in her article. It’s a cultural link of a different stripe which makes us think that rejoining was the right decision.

For what the UK and its fellow members have in common is that they are open societies, where information and people flow freely. The other possible partner, the USA, is showing strong signs of both damaging the free flow of information as well as launching major attacks on both the funding and the very work of scientists, as our readers well know. The Horizon programme and the countries that contribute, are the genuine heirs of both the Renaissance and Enlightenment. Societies that abandon the practice of truth and reason soon fall into cultural and economic stagnation. Just as being in UEFA is a sound bet for British Football Clubs, so is Horizon for British Universities. A good news day forr once

Exclusive: We reveal the only definite finding from quantum physics(and you can be certain of it)

Always believe someone who tells you that they don’t know what’s going on. Especially when that someone is one of the best trained and most intelligent people in the world. That’s why this story from Nature Briefing caught our attention as the week-ender for this session of blogs: What Does quantum Physics Mean anyway?

First sketched out a century ago, the equations at the heart of quantum mechanics underpin technologies from computer chips to medical-imaging machines. But no one seems to agree on how best to describe the physical reality that lies behind the maths. A Nature survey of more than 1,100 researchers — the largest ever on the subject — has revealed just how widely researchers vary in their interpretations of the most fundamental features of quantum experiments, and their confidence in their answers. [1]

The survey asked questions like “is there a real quantum world behind – or does all this work we’ve done only represent what’s inside our heads? What are the most favoured explanations for quantum theory? What is a wavefunction anyway? Is there a boundary between classical objects and quantum objects (i.e ,between the table you’re sitting at and the atoms it’s made from) And the answers that came back-and remember who gave them-read more like the responses to political opinion polls or market surveys about the best brands of instant custard.

From all of which we concluded the following.

1 If the brightest and the best think like this about something they have studied for decades, it suggests the rest of us might do well to be a little less opinionated on many things

2 Above all this includes certain journalists who think they know it all on things like climate change, vaccines and global warming

3 Watch the last episode of Jacob Bronowski‘s TV spectacular The Ascent of Man on You Tube. or one of the other streamers. It’s still good after 52 years [2]

4 There is still much out there to discover-as we tried to hint with our little blogs on Euler’s number and π(LSS 14 3 22; 16 4 24)

5 All knowledge exists within certain limits, and is probable. Of this last point, you may be certain

Bacteriophages v Bacteria: this arms race offers opportunities

We’ve always hymned the praises of bacteriophages here (LSS passim): that they will be a vital second option to supplement the next generation of antibiotic drugs. But we have a confession. We didn’t understand them. We didn’t appreciate that they are biological systems (viruses) interacting with other biological systems (bacteria). And as such, will obey all the usual rules of all such systems, such as arms races between predator and prey, Now a new article by Franklin Nobrega for the Conversation puts that right. [1]

Bacteria have evolved some fascinating defence mechanisms to ward off the relentless attacks of their phage enemies. These involve cutting the nuclear material of the viruses: building up strong cell walls and cellular shutdown mechanisms which act a bit like your IT Department does when it detects a global virus attack on your building’s systems. Recently Franklin and his team have investigated an early warning system called KIWA which gives the bacteria advanced notice that an attack is imminent. To which phages have in turn responded by their own mutations, and so it goes on, etc etc.

There’s a lot to encourage us here. Firstly, human knowledge of bacteriophages and their ways is deepening all the time, always a good thing. In fact Franklin is part of the University of Southampton phage collection project which we showcased here a few weeks ago (LSS 1 7 25) More strikingly, as two systems attack each other in an arms race, they leave little gaps, tiny vulnerabilities, which outsiders can exploit. The promise of new drugs and new bioengineering techniques looks very real indeed. Especially, we suggest if information scientists and complexity theorists are brought in to work alongside the biological teams. All in all, a rather good day for those of us interested in the problems of microbial antibiotic resistance. Go boldly, gentle readers, and be of good cheer.

Heroes of Learning: Steven Rose (and why things are never simple)

No book ever tore through the calm assurances of progress through co-operation like Richard Dawkins’ The Selfish Gene. [1] It wasn’t so much the book itself. That was an attempt to popularise, albeit sometimes in colourful language, the discoveries of an important group of evolutionary theorists such as William Hamilton and EO Wilson. It was the use made of it by political activists, zealous propagandists of the Free Market, to prove that every attempt at co operation, collective action and sharing resources was against the basic laws of nature. “Out upon your Trades Unions, your Keynesian economics” they thundered in a thousand articles in places like the Daily Mail “we are nothing but animals. Your only purpose is to pass on your DNA to make copies of yourself. Look at them lions. mate! When one of them takes over a pride he kills all the cubs and mates wiv the females to make sure his genes get frough! Go and do like wise!” It was not an experiment we felt disposed to try. Compete, for the other fellow is your genetic enemy was their credo. All barriers to that competition were both evil and deluded.

It was simple, it was seductive, it was based on some facts. It played well in the broken restless zeitgeist of the 1970s when the pillars of the old prosperity- high taxes, demand management for the common good, collective institutions like the IMF and UN seemed ineffective. It sold by the million; and swept ever more voters into the booths for one Margaret Thatcher in 1979, whose own simplistic and reductionist nostrums seemed to chime so well with those of the book.

One man did not buy. His name was Steven Rose, a remarkably accomplished scientist who spent most of his work in neurobiology and biochemistry [2] This obituary summarises his work better than us. But it was his insistence on complexity and the irreducible flexibility of the human mind, that still allowed hope for a way out from the genetic prison in to which we had been so neatly incarcerated

He wrote: “It is in the nature of living systems to be radically indeterminate, to continually construct their – our – own futures, albeit in circumstances not of our own choosing.”

Look at that carefully, then leap with us to another part of the scientific forest. Where the BBC showcases a new technique to rid the world of the scourge of inherited mitochondrial disorders [3] Basically you take a fertilised ovum from a normal male-female coupling, but put it as the nucleus in the egg of a different female. Which then develops as a normal embryo until nine months later a healthy baby emerges[3] A three parent child? Sort of. Two parents get to pass on their DNA, no doubt to the blissful delight of Dawkins’ more extreme followers. And a different mother sends her mitochondrial DNA cascading down the ages, which rather complicates matters for some. Now look at the Rose quote again what was that about continually constructing?

At the time of the great Dawkins controversy the old BBC Horizon programme ran a show in which the quoted one of the wiser and more humane scholars in the Selfish Gene camp. His name was John Maynard Smith. And he ended with this thought “humans are not just animals- we are not prisoners of simple genetics” At the time it seemed a forlorn hope. It has just been proved triumphantly real.

Weekly Round up: Air Pollution, Gene therapy and raspberries

Air pollution is the new smoking Stopping smoking has led to massive falls in rates of lung cancer. But this fearsome disease is still lurking out there. The current cause? Air pollution ,as Ian Sample explains for the Guardian

Gene therapy chalks up another win Ok,today it’s one particular form of deafness, attributable to one particular gene, as Maoli Duan explains for the Conversation. But: the more science you do the more you learn. Meaning other disabilities may one day prove susceptible as well. And the more you spend on scientific research the more you get benefits like this. A lesson rapidly being forgotten in the United States of America

Machines that out think humans It’s the scary nightmare of science fiction films from Blade Runner to the Terminator series. Up until recently the idea still seemed to be fiction. All that may be about to change as Nature Briefing reports

An artificial-intelligence system called Centaur can predict the decisions people will make in a wide variety of situations — often outperforming classical theories used in psychology to describe human choices. Trained on data from 160 psychology experiments in which 60,000 people made more than 10 million choices, the system can simulate human behaviour in tasks from problem-solving and gambling, and even those it hasn’t been trained on. Using Centaur, “you can basically run experimental sessions in silico instead of running them on actual human participants”, says cognitive scientist and study co-author Marcel Binz.

Friday Night Feast Raspberries and Ice cream We are not all gloom and serious stuff here. Thinking it was time for a quick Friday Fun feature, we realised that we’d done strawberries several times (LSS passim), In which case the humble raspberry can make a really pleasant alternative, especially if combined with ice cream instead of cream. After all, even if we are on a diet-you, gentle reader may not be. So- eat a bowl for us we used to love it.

Round Up: Gulf Stream collapse. stem cells rule the world, and much more

an ever-so-slightly flippant look at stories from near and far:

Gulf Stream Collapse If the Atlantic currents fail, life as we know it in western Europe will be pretty much unsustainable.

This is what awesome intelligence looks like

No we’re not writing about ourselves as some hardened readers may have already guessed. Because we couldn’t achieve what the researchers in these two stories, both from Nature Briefing, have indeed achieved. Sorry guv- we don’t have their intellectual bandwidth . Cognitive intricacy. Brains, in good old fashioned English But we know intelligence when we see it, and we know you do too.

Algorithms design remarkable enzymes Researchers have used computer algorithms to design highly efficient synthetic enzymes from scratch, reducing the number of tedious hands-on experiments needed to perfect them. The products facilitate a chemical reaction that no known natural protein can, with an efficiency similar to that typically achieved by naturally occurring enzymes. One design was also 100 times more efficient than similar enzymes previously crafted using artificial intelligence. In comparison to enzymes that occur in nature, the algorithm’s creations are less complex and can’t grapple with multi-step chemical reactions, but they’re proof that the approach has promise.Nature | 4 min read

The medical potential of designer enzymes will not be lost on readers as intelligent as our own. Yet some discoveries are to be relished not for their use, but for what they tell us about the world and our real place in it Try this for size

Dragon Man was a Denisovan Ancient proteins and mitochondrial DNA extracted from the ‘Dragon Man’ fossil — a cranium found in northeastern China that is at least 146,000 years old — have confirmed that it belonged to a Denisovan, an archaic human group. The fossil is the first skull to be definitively linked to the group, which sheds light on what the ancient people looked like, putting an end to decade-long speculation.Nature | 5 min read

Faecal Pellets: Watch the good bacteria chase out the bad

Imagine you get bad news: antibiotic resistant bacteria have set up a colony in your intestine. OK here’s some worse: they could escape and invade your blood, kidneys, whatever. In which case you have real problems. This is a very real scenario which that brilliant researcher Dr Blair Merrick of Guys and St Thomas Hospital has sought to address. [1] as reported by James Gallagher of the BBC Why not, he has reasoned, get some good non resistant bacteria to chase out all those bad ones? It is his chosen method which may raise more than one eyebrow among you, gentle readers

According to Dr Merrick, the way to get the good bacteria into his subjects is via pills made of…..well, made of faecal matter, you know,,,poo. To quote James:

Dr Merrick says there are “really promising signals” that poo pills could help tackle the rising scourge of superbugs and that donor bacteria could be going to microbial war with the superbugs as they compete over food and space on the lining of the gut and either rid the body of them completely or “reduce them down to a level that doesn’t cause problems”.

We like this for all sorts of reasons. Firstly the gut really is such a good harbour of antibiotic resistant bacteria. Secondly, as in all things ecological, making its flora more diverse can only be a good thing. Thirdly, we think it has a clever little principle behind it. Antibiotic resistant bacteria have devoted a tiny bit more of their genome to this purpose than non resistant ones. In the world of ecological competition, where tiny differences can make an enormous difference to long term survival, this could be crucial. If done correctly, the good non resistant ones should out compete the bad ones.

It’s early days yet, and the early trials have only been on 41 subjects But as seasoned veterans of the long wars of antibiotics will know, we at LSS welcome every initiative, however unusual it may at first seem. We wish every success to Dr Merrick and his team and hope that their early accomplishments continue in the bigger trials to come,
