Are we a product of the times?

Alfred Russell Wallace (1823-1913) was a product of his times

Mr Wallace was truly remarkable, a gentleman in the time when such a description meant something, and a traveller when getting from one town to another in England was a feat of endurance.

In the mid-1800s he covered the length of the Malay Archipelago on limited means. Which actually meant he was wealthy beyond belief to most of the indigenous peoples he met but had limited old money when compared to his peers back home.

Wallace was a naturalist and collector of exotic animal specimens caught or shot in the jungles and mountainsides at dozens of locations on remote islands. He made what money he could from the sale of preserved bird skins, mammal skeletons and pinned insects to museums and his less adventurous fellow gentlemen collectors back in Europe.

He was also an extraordinary observer able to recall almost at once if a butterfly or beetle was new to his collection. Anyone who has dabbled in natural history collections will recognize this skill. A good naturalist needs to be proficient at it and Wallace was, by all accounts, exceptional.

But what made Wallace truly remarkable was that he didn’t just observe nature, he observed people too. He saw the forms, behaviors and habits of all the locals he met on his travels. Indigenous peoples and colonists alike, they all fascinated him. And then he tried to explain the patterns and behaviours in the people with the same logic he applied to nature.

No doubt he also carried with him the prejudices of his peers. His times were of colonial rule, the greatness of empire and knowing one’s place in the pile. It is unlikely his observations were not clouded by at least some prejudice.

His seminal work “The Malay Archipelago” is well worth its 500+ pages. At once a primer on natural history, a window into thinking on the theory of evolution, a catalogue of the biology and peoples of the region, a gentleman’s travelogue, a commentary on economics and an insight into how the Victorians saw the world. Often the prose carries all these things in the space of a few pages.

By Unknown author – Marchant, James (1916) Alfred Russel Wallace — Letters and Reminiscences, Vol. 1, London, New York, Toronto and Melbourne: Cassell and Company, pp. Plate between p. 36–37 Retrieved on 16 October 2005., Public Domain, https://commons.wikimedia.org/w/index.php?curid=372562

Famously Wallace figured out what Charles Darwin, his contemporary, himself became famous for, the theory of evolution by natural selection.

Crossing the deep and treacherous straits between Bali and Lombok in 1859 he landed and began collecting no doubt with an expectation of what he would find. Only there was a large number of species that to the west were organisms related to Asiatic species and to the east a mixture of species of Asian and Australian origin.

Wallace saw in that line, later named the Wallace Line after him by Thomas Huxley, a disruption to the pattern that he expected to see. The continuous variation that he followed in the myriad diversity of animals that fell into his traps should not have such an abrupt disjunct.

The genius of Wallace, that he shared with Darwin, was not only to recognise the disjunct but to realise it meant something profound.

Gathering his observations together he figured out what Darwin had also discovered, the concept of evolution by natural selection.

His views diverged from Darwin’s but the two through both private correspondence and published works exchanged knowledge and stimulated each other’s ideas and theories over an extended period and they both agreed on the importance of natural selection, and some of the factors responsible for it: competition between species and geographical isolation. They diverged on why. Wallace gave evolution a purpose in maintaining species’ fitness to their environment, whereas Darwin hesitated to attribute any purpose to a random natural process.

Although we now agree with Darwin on the randomness part, Wallace remained an ardent defender of natural selection all his life. And remember this was highly contentious stuff at the time. In 1889, Wallace published the book Darwinism as a response to the scientific critics of natural selection.

It was what a gentleman would do.


This gushing account of Alfred Wallace was written a year or so ago after I had read the Malay Archipelago.

I was and still am amazed what some of the old-timers managed to get done and more, to figure out what a bunch of it meant. They are inspirations.

As I finally got around to editing the post, I am struck by how little the gentlemen and women of today inspire me. Where are they? I have to assume that they exist.

They do not seem to be among the celebrities or the internet influencers who are driven only by narcissism.

Heaven help you if you try to find them in seats of government.

They are not in the business community that continues to promote the economic model that is both precarious and gives not a jot about the resource base — much of the biology that Wallace saw is gone forever.

They are not among the clergy. I cannot even bring myself to go there.

Perhaps, and here is a left-field assertion that I never thought was possible. Perhaps they are hiding among the scientists.

I know, crazy suggestion right.

We are talking about the fence-sitting nerds who have bamboozled us for decades and failed miserably to get their messages across.

Well, there is an idea going around promoted by Sir Paul Nurse, Nobel Laureate and chief executive of the Francis Crick Institute that the response to the COVID-19 pandemic is to cause science to be done differently with collaboration, speed and efficient up there as the biggest changes.

That in this time of crisis it is the scientists who are working together to us get through it all as fast as possible while their fellow technical specialists doctors, nurses and support staff on the front line provide the heroic bravery.

That sounds like what gentlemen would do.

Should our leaders know about the process of science?

Should our leaders know about the process of science?

Short courses in science and statistics should be mandated for all politicians because of their importance to so much public policy. And because so few demonstrate any knowledge of even the basic process of science.

Ian Chubb, neuroscientist and former Chief Scientist of Australia

Do you know the basic process of science?

Maybe you have a distant memory of a school teacher saying something about cause and effect or experiment or maybe hypothesis. Perhaps you were told to mix a few chemicals in some test tubes and record the colour changes.

Well, that’s it in the formal sense — the testing of hypotheses through controlled experiments. All that stuff about the scientific method.

It began with the Scientific Revolution in Europe towards the end of the Renaissance period and continued through the late 18th century when developments in mathematics, physics, astronomy, biology, and chemistry transformed the views of society about nature.

This period is also known as the Enlightenment when a few radical thinkers decided they had had enough of religions telling them obvious lies about the world around them. The likes of Beccaria, Baruch, Spinoza, Diderot, Kant, Hume, Rousseau, and Adam Smith decided a better approach was needed, one based on fact, things known to be true.

Now let’s see what happened next.

The rise of democracy, the industrial revolution, huge increases in health and well-being for more and more people.

The average westerner now lives in more luxury and comfort than Louis XIV, the king who was miffed at all those philosophers bursting his bubble. Way more in fact.

The arts and social science types will not be happy that I am suggesting progress is down to the natural sciences, but you have to admit, it put a rocket under the process. The changes seen in societies across the globe in the last 200 years have been so much faster than at any other time in human history.

In short, science is important.


It makes good sense for leaders as well as thinkers to at least know how science works and something about the philosophy behind it. Especially the idea that the scientific method generates evidence, facts know to be true.

It is vital that decision-makers know what is known and how reliable that information is. We took the piss out of Donald Rumsfeld but actually, he was onto something, although he was lampooned for saying it.

The scientific method and the results from the researchers who apply it reliably generate the facts that give us the full suite of knowns.

Professor Chubb said something else. He also wanted the political muppets to know about statistics.

He is spot on.

Without the basics of probability — how likely something is to happen — combined with an understanding of the scientific method, the results of research and the advice of the experts are meaningless.

Probability seems quite difficult to understand for most people. Here are a few conundrums as examples…

  • If I toss a coin and get five heads in a row, what is the probability of the next coin toss delivering heads? Exactly 50%, just like it was for the previous five tosses.
  • The median is not the same as the mean even though they are both measures of central tendency unless the data is normally distributed.
  • An unlikely event is not impossible — ask Nassim Taleb about black swans.
  • Correlation is not causation.
  • And here is a statistic that everyone should know — 8,000 per hour

These statistics and likelihoods and measures of distributions are not lies, they are vital to understanding risk and opportunity, the very essence of what policy for the collective benefit should be about. Minimising risk and maximising opportunities for as many citizens and visitors as possible.

Politicians are ignorant of this at our peril.

Why we forget to ask if its fake or fact

Why we forget to ask if its fake or fact

Here is a list of some of the choicest statements from the president of the United States, the so-called head of the free world, about then Secretary of State, Hillary Clinton…

  • She has a serious chronic illness
  • She is sleeping all the time
  • She founded ISIS “literally” with President Obama
  • Trump blamed the tax code that allowed him to not pay millions in taxes on her
  • She wants to eliminate the second amendment
  • She started the birther movement
  • She will be indicted (after Comey’s letter to Congress)
  • Her Emails (in relation to Anthony Wiener’s computer) are worse than Watergate

Founded ISIS, always asleep, started the birther movement… for goodness sake. And it helped get him elected. What is wrong with people?

This stuff is just ugly and anyone should know that it is fake.

Each one either a blatant falsehood or hugely disrespectful drivel that I really shouldn’t be printing again.

No matter what your political allegiance nobody should have anything to do with such nonsense. It demeans everyone, especially the person who went on the be the president. Please, heaven help us all.

These choice examples are easy to spot as fake. There is not even a loose fact among them.

What about these…

  • Urgent: Koalas could be extinct in NSW as early as 2050. We can’t let this happen — WWF website
  • “Climate change has not caused the [2019-20] bushfires, unprecedented arson has” — Australian Liberal MP Craig Kelly
  • An electric vehicle won’t tow your trailer. It’s not going to tow your boat. It’s not going to get you out to your favourite camping spot with your family.” Australian Prime Minister Scott Morrison
  • I want to stress that for the vast majority of the people of this country, we should be going about our business as usual.” UK Prime Minister Boris Johnson on 3 March 2020

How do you decide if these claims are fake or fact? Do you even bother? It is hard after all.

Most information comes at us all polished and convincing. The presenters are slick, the writers persuasive and the messages short. Why wouldn’t we believe such well-rounded packets of influence?

All of those in the list above are false with only modest provisos.

There are many reasons for our failure to spot fake claims and fake news

Information overload

An average smartphone owner in a mature economy is exposed to more information in a day that many of our ancestors saw in their lifetimes.

Here is what one set of information scientists think goes on…

In 2011, Americans took in five times as much information every day as they did in 1986—the equivalent of 174 newspapers. During our leisure time, not counting work, each of us processes 34 gigabytes, or 100,000 words, every day. The world’s 21,274 television stations produce 85,000 hours of original programming every day as we watch an average of five hours of television daily, the equivalent of 20 gigabytes of audio-video images.

The reliability of these numbers is not important here. The point is that we are all awash in information, all the time we are awake.

This can swamp our filters and certainly our reflection time so a lot of information is believed to be true because there is not time to decide otherwise before the next packet of critical information arrives.

Much of the information we receive is true

When your phone beeps an alert that your 9 am meeting is in 10 minutes, it is true. There is no reason to ever doubt it.

When you press the icon in your favourites tab to ring your better half and its answered, hostile takeover or the cleaner being helpful notwithstanding, it will be your better half who answers.

If my phone rings and the icon says it is my sister, I answer. When she tells me that my mother passed away in the night, I believe her.

Read a tweet from Brixton Barry that says “Holy shit, here is a riot going on” and, well, maybe there is, Brixton has had riots before… And why would he call himself Brixton Barry unless he… well, you get the idea.

But hold on, that was a long time ago and who is Barry? In this case I would be sceptical unless more tweets began rolling through the feed, perhaps with an image or two, before I believe what Barry is saying.

It is more likely that the tweet from Brixton Barry passes by my sceptic filter because so much information already has and has not caused an issue.

Plus if I live in Detroit or Hounslow, a riot in Brixton might not be worth a fact check.

An endnote

Here is what the late, great author Terry Pratchett said about the spread of fake news on the Internet back in 1995…

“Let’s say I call myself the Institute for Something-or-other and I decide to promote a spurious treatise saying the Jews were entirely responsible for the second world war and the Holocaust didn’t happen and it goes out there on the Internet and is available on the same terms as any piece of historical research which has undergone peer review and so on. There’s a kind of parity of esteem of information on the net. It’s all there: there’s no way of finding out whether this stuff has any bottom to it or whether someone has just made it up”.

Terry Pratchett

That was 1995 remember, near to the beginning of the whole internet age. It was prescient certainly but it was also sage advice.

Go to the source for any information that is important and if there is no source, go generate that information yourself.

Cardiologist

Cardiologist

Just before the lockdown, I made my annual pilgrimage to the hospital to see my cardiologist. It’s a long story to do with genes and familial lines and some inevitabilities of the way biology works.

The visit was a success from my end thanks to a fine doctor who is a sensible and pragmatic professional. His motto seems to be ‘if it ain’t broke don’t try to fix it’. This is somewhat unusual in our interventionist times and a bonus for me because the last thing I want is another procedure.

Anyway, we dealt with my heart issues fairly briskly and got onto stress.

This was a problem for me and the cardiologist agreed although he was quick to say that he was not qualified to advise on what I should do about it. My blood tests are good and my blood pressure in the middle of normal so from his perspective not much to be done.

My wife asked if retirement might be a solution.

“Oh no, that would not work,” he said, ‘you’re an environmental scientist right?”

“Yes,” I said.

“Well then, the stress will still be there even if you retire. This country is in a political mess.”

He was actually rather less polite than this but his point was a good one. There is a level of stress and malaise over many scientists right now in the age of spin, fake news and normative science.

Scientists, especially environmental ones, are purposely misunderstood, maligned and ignored.

I experience it every day.

When I try to speak the listeners switch off or glaze over. People seem to have no skills with logic and numbers and have no interest in gaining any. Anything more complex than 2 + 2 is near impossible to communicate.

The really important issues that involve an understanding of settled science, some skills with likelihoods, and the application of proper scepticism — these things are just not even in the conversation.


Why integrity and scepticism are inseparable allies

Time for scepticism

Why can’t I retire

Well, I can and I will, but only from the day job.

A lifetime of buzzing around as a lonely fly avoiding the wafts of the disinterested and the annoyed is debilitating. I’m knackered.

But then there the issues that still get me excited and incited. My normative feelings rush in and I’m wanting to say something, even if it is to extoll the virtue (another normative word) of being objective.

I will be my own worst enemy and keep on thinking about all this until I get hit by a bus.

Meantime there was another thing.

It was a relief to hear that the expert thinks my heart with its grafts is doing fine. Keep doing what you’re doing and come back in a year was the message. I will take that from a fellow scientist.

It was a shock to hear how much trouble he thought the world was in and that was before we had a pandemic.


A short primer

Normative science — science based on preference or value.

This means that it is not true science at all but an opinion or bias towards a particular outcome held by the scientist on her own behalf or by the people who support her.

Food and diet are obviously normative. They are both chockablock full of values. What we eat is what we can afford and what we choose based on our preferences that are rarely free of value.

There are ways to quite quickly decide if the science presented is normative.

1 – Look out for ‘is’ and ‘ought’ and value-laden words

In the English language, the difference between ‘is’ and ‘ought’ is critical. The use of the word ‘is’ determines a fact whilst ‘ought’ refers to an opinion.

Science should be all about the world of ‘is’, the facts about the past, present, or future. So if the language that a scientist uses has too many ‘oughts’ then there is a good chance she is being normative.

The use of ‘should’ is a giveaway too.

Bad, better, bigger, catastrophe, destroy, disaster, good, slashed, tremendous, ugly and all similar value-laden words and phrases are red flags for normative language.

2 – How was the evidence generated

True scientific evidence comes from deduction. This is a process of setting forth an idea as a hypothesis and testing it with an experiment where treatments are assigned to observational units at random.

Some evidence comes from observation alone. As the plane flies low over the savannah the elephants browsing below are counted. This tells us how many elephants there are viewable from the aircraft — an observation.

It is only an estimate of how many elephants there might be all together and tells us nothing about what elephants do or if their numbers are decreasing or on the rise.

The quality of evidence to explain how things work is really what science is about. Observation alone is rarely enough.

3 – Who provided the evidence?

If you are paid $100,000 a week to play soccer for a premier league team you would not want to score goals for the opposition. You are paid to score goals for your team.

Scientists are prone to this employer bias as much as anyone. If your boss wants to see great yield response in trails of the companies new fertilizer it will be hard to present evidence to the contrary. He might say you had a poor design and get you to repeat the experiment or worse.

Ask yourself who generated the evidence as well as how they did it. Academics are less likely to be based than scientists working for commercial companies and those who work for government agencies might be somewhere in between.

Beware though, for no one is immune.

Something that should be more worrying than COVID-19

Something that should be more worrying than COVID-19

Insects are by far the most varied and abundant animals, outweighing humanity by 17 times, and are essential to the ecosystems humanity depends upon. They pollinate plants, are food for other creatures and recycle nature’s waste.

Damian Carrington, Environment editor, The Guardian, 24 April 2020

Nearly two years ago Alloporus first noted some worrying research on the decline of insects in Europe. with the key finding

More than 75% decline over 27 years in total flying insect biomass in protected areas

Hallman et al (2017)

Alloporus’ comment was this

When an observation so dramatic and material to so many key ecological processes becomes known we dismiss it at our peril. If we ignore these numbers just because we like the idea of fewer midges at summer evening picnics without looking deeper to find out what is going on, we increase the risk to our already precarious food security.

At around the same time this post and research came out, two US researchers returned to a forested conservation reserve in Puerto Rico after 35 years and this is what they said…

We compared arthropod biomass in Puerto Rico’s Luquillo rainforest with data taken during the 1970s and found that biomass had fallen 10 to 60 times. Our analyses revealed synchronous declines in the lizards, frogs, and birds that eat arthropods.

They published their results in a peer-reviewed journal of the US National Academy of Sciences

Lister, B. C., & Garcia, A. (2018). Climate-driven declines in arthropod abundance restructure a rainforest food web. Proceedings of the National Academy of Sciences, 115(44), E10397-E10406.

The declines the authors put down to climate. It was too hot too often for the ground-dwelling invertebrates creating an upwards cascade through the food web.

In Europe insecticide use and habitat change, in a rainforest, climate change. Either way a serious problem.

Just to make sure this was not just an isolated result, Roel van Klink of the German Centre for Integrative Biodiversity Research, together with colleagues from around Germany and Russia completed a meta-analysis and

‘compiled data from 166 long-term surveys across 1,676 globally distributed sites and confirmed declines in terrestrial insects, albeit at lower rates than some other studies have reported and concluded that ‘Patterns of variation suggest that local-scale drivers are likely responsible for many changes in population trends, providing hope for directed conservation actions.’

So it’s happening. Roughly 25% declines in insects across the board in a generation, with insects faring only slightly better in nature reserves than outside protected areas.

The conclusion, terrestrial insects are declining in numbers and variety and, as is typical for nature, this loss is patchy, occurs at differing rates and from multiple causes.

Klink and his colleagues took hope from this result. You can see why. If climate change was the cause everywhere, then there is a serious global catastrophe in the offing where the rates of decomposition and nutrient transfer are altered across a wide range of biomes and habitats affecting many land uses, especially primary production.

This would not be about species loss in the way it is for the koala. A cute thing that we like to see in the zoo and maybe take a selfie with one held up by a zookeeper, the cuddly critter that might become extinct. This is about the loss of function, loss of ecosystem services that we cannot do without or easily replace.

Instead, Klink and his colleagues found multiple, often local causes. This they interpret as a solvable problem. Conservation and restoration efforts could help local populations recover.

As regular readers will know, Alloporus has to work hard to be this optimistic.

Until the economy through the supply chains feels the hit of the loss of services little will be done. The efforts of the few with the koala saving gene will be epic, they will try their best, but it will not be enough.

If lockdown with its boredom, ingenuity and the appearance of clean air all around the place tells us anything, it should be that we can survive on relatively little.

Only part of that little has to be food and water.

Imagine lockdown with the supermarket shelves empty of food. That would put toilet paper shortages into perspective for us.

It is trite to say it, and sad that it has to be said again and again, but it is true — nature matters to our very existence.
