Manipulation of evidence

Research studies routinely use different ways to present their conclusions. In particular they present “relative risk”, “absolute risk”, and/or “numbers needed to treat” information. Gigerenzer is brilliantly clear about this. He says

Gigerenzer shows how drugs companies and authorities routinely use Relative Risk to emphasise the potential benefits of their treatment while at the same time presenting the potential harms as Absolute Risks to minimize the impression of adverse potential.

This week in the BMJ, there is a study where researchers have looked at the use of relative and absolute risk reporting in studies which examine inequalities in health. Their argument is quite modest – that to fully understand any study BOTH relative and absolute risks should be reported. They say this is best practice. So, how often does it occur?

Almost never.

75% (258/344) of all articles reported only relative measures in the full text; among these, 46% (119/258) contained no information on absolute baseline risks that would facilitate calculation of absolute effect measures. 18% (61/344) of all articles reported only absolute measures in the full text, and 7% (25/344) reported both absolute and relative measure

But in fact, the literature is even more skewed than those conclusions suggest because

We found that nearly 90% of studies with quantitative estimates in the abstract presented only relative measures, and 75% of all articles reported only relative measures in the full text.

Why is the bias towards relative risk even greater in the abstract than in the full text? Because its the abstract which most people read, and it is probably the abstract which is used to write the PR headlines.

Does this matter? Yes it does. The authors argue that the choices of relative or absolute risk reporting influence policy making.

Makes you wonder how often the “evidence” is produced to fit the policy, rather than the policy being produced from the evidence…….and that applies across the board from the writing of guidelines and protocols, to decisions about health care spending, to individual doctors deciding what treatment to offer an individual patient.

Complex or complicated?

What’s the difference between a complex system and a complicated one?

It’s all in the number of connections.

A complicated mechanism is just that – a mechanism. Like a machine. It may be built up from lots of different components and parts (think of modern cars with their onboard computer systems), but each part interacts with very few other parts. So if you want to understand it you can take it to pieces and understand each part, then build it back up if you know how each part connects to other parts.

A complex system is not like a machine. It may also have many different components and parts (think of a brain with all its neurones) but each part has multiple connections with other parts, and each part can in turn be influenced by multiple other parts. You cannot understand this by taking it to pieces. Its characteristics are dependant on the whole interactive system. A single part, or even set of parts, will not necessarily behave the same way when considered in the entirety of the whole organ.

All life forms are complex systems, not complicated systems. Treating human beings as machines is a failure of understanding.

The current set of concepts being used to organise health care prioritise a certain reductionist view and assume the ability to predict outcomes of actions – as if health and health care were linear systems (hint – they’re not! They are complex and non-linear). One of the consequences of this way of thinking is to break professional roles down to a series of tasks. Once a simple task is examined, it is usually possible to argue that only a little training and knowledge is required to carry out that task (just the skills and knowledge required for this particular task). What we lose sight of, is a person-level perspective, and hence a professional one.

Let’s consider one type of health care professional. A doctor. What is a doctor? What’s a doctor’s role? Actually,that’s not so easy to answer, but if you read “Tomorrow’s Doctors” by the General Medical Council, which is their attempt to describe what a doctor should be able to do, you’ll find a strong emphasis on leadership.

So, it was interesting to come across the concept of “humble leadership” which is beginning to attract attention.

In the midst of spectacular failures of the “superman” type of leader in the financial, corporate and political sectors, people are beginning to question the wisdom of seeking such charismatic but frequently arrogant individuals whose main strength seems to be the conviction of the rightness of their own decisions.

So what is a humble leader? Leadership humility…

generally involves how leaders tend to view themselves (more objectively), others (more appreciatively), and new information or ideas (more openly) 

And

The humble leader behaviors we identified (e.g. acknowledging mistakes, spotlighting follower strengths, modeling teachability) as well as the mechanisms (e.g. legitimization of uncertainty and personal development) were often described as directly challenging the more popular top-down conceptions of leadership.

As doctors are expected to be able to handle complexity and uncertainty, it would seem that humble leadership skills might be highly relevant. Wouldn’t you like your doctors to observe themselves more objectively, you and their colleagues appreciatively, and to be continuously open to new information and ideas?

Such a shift to humble leadership could completely change the doctor-patient relationship for the better. It is a much more appropriate way to deal with the reality of the complexity and uncertainty which is characteristic of human health and disease.

The researchers who are studying leadership humility identify two key characteristics or qualities – competence and sincerity.

Hard to argue with that!

Reduced Medicine

There’s a terrible tendency these days to reduce the practice of Medicine to a slavish following of protocols and guidelines. In society there is a strong drive to uniformity and conformity – but that drive doesn’t come from individuals. It comes from the machine-like models of corporations and corporate management methods.

Iain McGilchrist says, in The Divided Brain,

We kid ourselves that doctors, teachers, policemen are there to develop a ‘product’ which we can then ‘get’ or consume. But this is nonsense. We don’t know beforehand what it is we are to go after and ‘get’, because it varies in every single case, and is dependent on a relationship between individuals.

Yet it seems we are increasingly pushed to demonstrate “outcomes” which are set before we begin, and are measured (presumably) after we have “finished.”

I think the prime job of a doctor is diagnosis – in the old sense of the word – an understanding. In other words a doctor’s job is to understand. To understand a person and to understand what they are experiencing, whatever artificial label of a named disease we apply.

Understanding is never complete.

So, diagnosis is never finished.

The GMC, in “Tomorrow’s Doctors”, says that a doctor’s job is to be able to handle complex situations and to deal with uncertainty. We need a bit more of that. We need to shift the focus away from tasks, outcomes and targets, all of which imply products and endpoints, to human beings. Every single human being is unique, and nobody, but nobody, can accurately predict how the future is going to unfold for an individual.

Medicine is a relationship between two people. One acting in the service of another. It can’t be reduced to measurable tasks. And it certainly can’t be reduced to the act of writing a prescription!

In Praise of Love

“In Praise of Love” by Alain Badiou [1846687799] presents a simple but thought-provoking idea about love. He proposes that love is about the creation of a two person view of the world, instead of the single, individual one. As understood from a complexity position, what emerges in this linking up is greater than the sum of its parts

the real subject of a love is the becoming of the couple and not the mere satisfaction of the individuals that are its component parts.

Quite poetically he describes it this way

It is like two musical instruments that are completely different in tone and volume, but which mysteriously converge when unified by a great musician in the same work.

What really resonated most strongly with me, however, was his key insistence that love is about difference – about seeking difference, creating difference, delighting in difference…

what kind of world does one see when one experiences it from the point of view of two and not one? What is the world like when it is experienced, developed and lived from the point of view of difference and not identity? That is what I believe love to be. It is the project, naturally including sexual desire in all its facets, including the birth of a child, but also a thousand other things, in fact, anything from the moment our lives are challenged by the perspective of difference.

Beautiful.

This is a different view of love from the traditional romantic love, which, sadly, I feel, too easily slides into something which turns one person into the love object of the other. I prefer Badiou’s idea – it’s more equal, and, ultimately, incredibly more exciting….

Emeli Sandé sang a beautiful version of Read All About It, Part III at the closing of the London Olympics, and the line “we’re all wonderful, wonderful people so when did we all get so fearful?” has been running through my brain ever since.

(I’ve embedded the video link here, but you’ll see the Olympic Committee insist you go watch it on youtube….go on, click the link…it’s worth it!! The lyric in question comes in at the 2 minute mark….)

The Divided Brain

Iain McGilchrist has released a short Kindle book entitled The Divided Brain and The Search for Meaning [ASIN:B008JE7I2M]. In it he presents an excellent precis of the ideas and findings he presents so brilliantly in his somewhat massive The Emperor and His Emissary.

The key to his thesis is that it is odd that our brains are divided into two asymmetric halves. Why is that? Why didn’t we just develop a single, unified cortex? There’s probably some big advantage in having two brains, but only if the two halves let us do different things. This is NOT an argument that the left does this and the right does that. It is NOT a claim that left-brained people deal with facts, and right-brained people are artistic. He dismisses such ideas as simplistic and erroneous. As he puts it –

Instead of asking, as of a machine, what it does – does it ‘do’ reason, emotion, language, imagery? – we should have asked – as of a person – what’s he or she like?

In other words, what are the different ways each hemisphere approaches the world?

He says that the right hemisphere primarily lets us be aware of the world, and looks for the connections, or the “between-ness” everywhere, whereas the left allows us to grasp, and, hence, manipulate the world.

The right hemisphere underwrites sustained attention and vigilance for whatever may be, without preconception. Its attention is not in the service of manipulation, but in the service of connection, exploration and relation…….One way of looking at the difference would be to say that while the left hemisphere’s raison d’être is to narrow things down to a certainty, the right hemisphere’s is to open them up into possibility.

These differences are profound and we need them both. the one helps us to pin things down, and the other opens us up to seeing change and possibilities.

Another way of thinking of the difference between the hemispheres is to see the left hemisphere’s world as tending towards fixity, whereas that of the right tends towards flow.

In his thesis, he claims that the left hemisphere way of engaging with the world has become unhealthily dominant and we’ve become stuck on its way of representing reality to us.

the purpose of the left hemisphere is to allow us to manipulate the world, not to understand it.

I highly recommend you get this book. You can easily read it through at a single sitting, then you’ll want to go right back to the start and read it again. If you haven’t read The Master and His Emissary, The Divided Brain will whet your appetite but it will also let you easily understand the basic premise.

The right hemisphere seems to be involved more with new experience, new events, things, ideas, words, skills or music, or whatever it may be, while they are still fresh, original and unique, and so to speak present, to the mind.

The left hemisphere abstracts and generalises, where the right hemisphere’s world remains truer to each embodied instance, and appreciates the unique.

Just stop and think for a moment what that means, and why we should want to re-balance our society by shifting the balance to the right hemispheric way of approaching the world…..

 

Einstein  said that an important question to ask ourselves is “Is the universe friendly?”

It’s an interesting question because the answer you give influences how you experience Life.

If you think it is unfriendly, you are likely to see danger all around and to expect hostility. You are likely to respond by trying to control and conquer in order to be safe. If you think it is neither friendly, nor unfriendly, then you probably experience Life as random, brief and pointless. However, if you think it is friendly, you are more disposed to engage with an open-hearted curiosity, seeking to understand more and more.

This question which he posed is often considered in relation to thinking about the emergence of consciousness in the constantly evolving universe.

An article in this month’s Psychology Today refers to the question in this context. It’s worth a read, and concludes

Any inventory of the cosmos that omits us is like a survey of the body that overlooks the brain. In evolving the human mind, the universe has fashioned an instrument capable of understanding itself and empathizing with others. We are that instrument, and since we are part of the cosmos, we err if we judge it to lack kindness, love, and compassion. If I believe the universe is heartless, it’s because I myself do not love

Making a home

These are unusual nests, aren’t they? Like low hanging fruit from the trees, or lanterns shining on the lake.
Here’s one in the making….

You can see why the bird who makes this kind of nest is called a weaver bird.

Here’s something else unusual about these little homes…

The entrance is underneath!

Every single one of these nests is unique, because every single one is woven by the bird who is going to live in it. But they don’t want to be completely alone, so several of them build their nests in the same tree. It’s a little village. A small community. Every one of these communities is unique too, each one being in a different tree, each community created by a different group of individual birds.

The Universe has a creative flow.

Everywhere you look you can see differentiation and diversity, and the building of more complex phenomena from simpler parts.
Take a look around you today. Where do you see this creative flow in action? Where do you see diversity, uniqueness and the creation of links and connections?
