Studentships to study the nature of information at The Open University

The department where I work at the Open University in Milton Keynes, UK, is offering two full-time PhD studentships.  The details are here: 

Note the deadline of 10th March

Applications are invited to work in any of the fields of interest of the department, and that includes the study of information.  See the list of topics of interest here:,

but note especially:


Both of these would be based in the DTMD Research Group.

If you might be interested in studying for a PhD in either of these areas, or you have an idea for a related topic, please get in touch with me (david.chapman[at] as soon as possible.

And please pass this on!

Is the information of physics 'about' anything?

The New Scientist has been talking about reality again, and concludes:
"But to Susskind [Leonard Susskind of Stanford University] at least, the idea that reality might be rooted in 0s and 1s is poetically beautiful. Perhaps, he says, we will one day be able to sum up the universe in a simple epigram: “ah, everything is information”".

Note, though:
"[T]he sort of quantum information that might underlie space-time must be a little different [from Shannon information]. The information in a stream of words is about something. By contrast, the quantum information from which space emerges in Carroll’s [Sean Carroll of the California Institute of Technology] work is just there. “The quantum state is not of or about anything,” says Carroll. 
One of the ongoing issues in information research is whether a unified theory of information (UTI) is possible. I've recently been thinking of it in terms of a unified narrative of information: an agreed way of talking about information, and trying to come up with the things we can say about whatever it is we are calling information. One of those things seemed to be that it is always about something. (Though we have to be careful about what it means to 'be about' something. I think my trapeziums help.)  So, here's a question: could it be that the physicists are wrong? Could it be that even their information is about something? Could it be that in order to understand 'reality' you need a type of information that is about something? Could it be that they are missing something?

Anyway, here's a fuller quote from the New Scientist article.
It is all very well to suggest that space and time are made of quantum entanglement and possibly quantum complexity – but what are they made of? Here is where we edge closer to finding the true bedrock of reality. Because both approaches suggest the same tantalising answer: information.

The mathematician and engineer Claude Shannon gave us a neat way to define information in 1948. He showed that the amount of information in something like a stream of bits or letters is related to its entropy, a measure of disorder. The greater the entropy, the greater the information. For example, a stream of three-bit numbers that are always 000 contains less information than a stream in which the numbers can also be 001, 101 or 111.

So in what sense is information at the root of things? Well, entanglement is information: the greater the entanglement between two systems, the more information they share. But there’s a caveat. The information Shannon defined certainly seems to exist and has real effects. Experiments just last year showed a nanomachine could use information to chill metal. But the sort of quantum information that might underlie space-time must be a little different. The information in a stream of words is about something. By contrast, the quantum information from which space emerges in Carroll’s work is just there. “The quantum state is not of or about anything,” says Carroll. “It is simply our best mathematical description of the universe.”

It actually makes sense that quantum information would be the foundation everything is built on, says Carroll. If you start with quantum mechanics and don’t presume anything else exists, then “basically all you have to play with is quantum information”. That would make information a basic constituent of the universe. “You can find people who think that information is all there is,” says Carroll.

DTMD 2017: Information, Narrative and Rhetoric: Exploring Meaning in a Digitalised Society

The DTMD Research Group has launched the Call for Papers. It always irritates me when people say 'we are excited about...' and then go in to talk about some tedious, mundane or even negative development, but this is different: I really am excited about DTMD 2017!


The sixth Difference that Makes a Difference conference, DTMD 2017, will form part of the IS4SI 2017: Digitalisation for a Sustainable Society summit, which will take place 12-16 June 2017 in Gothenburg, Sweden, on the theme of:

Information, narrative and rhetoric: exploring meaning in a digitalised society

Meaning is embedded within, and defined by, stories. This workshop will explore the use of the language of information in the stories of the digitalised society in order to enhance understanding, both of society and of information.

In our increasingly digitalised society, certain narratives have emerged depicting possible futures of an information society. ‘Smart cities’, ‘big data’ and ‘the internet of things’ constitute perhaps the most obvious examples of such stories, offering somewhat utopian views of a society enhanced through their application. On the other hand digital technologies such as websites and social media are implicated in the spread of fake news and the rise of post-truth politics. Discussions of these developments engage with information and a shared, tacit understanding of its nature in order to generate meaning, rhetoric and the narratives themselves; reflexively, there is also a need to consider the role of rhetoric and narrative in the shift to a digitalised or informational conception of society. The exploration of information and its use, and their intersection with rhetorical considerations gives rise to alternative viewpoints and prompts a range of questions, thereby providing the basis for a valuable critique of emerging ideas and narratives.

In this workshop, the Difference that Makes a Difference (DTMD) group will continue its interdisciplinary/transdisciplinary exploration at the intersection of information and other phenomena by exploring its relationship to narrative and rhetoric. These conversations between – and across – disciplines encourage new perspectives and foster insight into the meanings and values we apply to our lives and way of living.

The workshop will address the following questions (among others):
  • How is information represented/embodied through stories and narratives?
  • In what way do the structures (e.g. shape and grammars) of stories create information in themselves?
  • Is it necessary to have both rhetoric and narrative to create stories? Can narrative-free or rhetoric-free stories exist? For example, can a bitstream or a DNA sequence be considered a story, or do mathematical equations form narratives in themselves?
  • What are the processes by which narratives are formed? How are meta-narratives formed, and what is their reflexive relationship with the information that the narrative shapes and is shaped by?
  • Are there circumstances when the forming of a narrative leads to the destruction or ignoring of information? Likewise, are there circumstances when the destruction of a narrative leads to the creation of information?
  • How do narratives become hegemonic on particular topics, for example, in political discourse? Who has the power to create and shape these hegemonic narratives?
  • What does the relationship between information and narrative say about the rise of post-truth politics?
  • What is the relationship between levels of abstraction (in Floridi’s sense) or levels of communication (in the sense of the ISO 7-layer model) and narratives?
  • Which narratives, particularly in public discourse, are generated in ways that (deliberately or tacitly) exclude information from discussion rather than adding to it?
  • How can we identify and investigate the narratives around digitalised societies, and critique the assumptions behind those narratives?

Keynote speaker

The conference will be opened by our keynote speaker, Ken MacLeod. Ken is a celebrated science fiction writer based in Edinburgh, Scotland, and has written many novels which look in various ways at the relationship, both utopian and dystopian, between technology and society. He has been described as “one of the most consistently interesting authors we have in contemporary science fiction”. He has been a writer in residence at the Genomics Forum and the Creative Writing MA course at Edinburgh Napier University.

Information is provisional - sinking of the Titanic

For an example of the provisionality* of information I've previously used the case of Lance Armstrong being stripped of his Tour de France wins.

*In, for example, the talk at DTMD 2013 (see 'Information is Provisional' in the Abstracts Booklet - it looks like I didn't mention it in the follow-up paper).

This might turn out to be a more interesting example:
The sinking of the RMS Titanic may have been caused by an enormous fire on board, not by hitting an iceberg in the North Atlantic, experts have claimed, as new evidence has been published to support the theory. [...]

Journalist Senan Molony, who has spent more than 30 years researching the sinking of the Titanic... said: “The official Titanic inquiry branded [the sinking] as an act of God. This isn’t a simple story of colliding with an iceberg and sinking.

“It’s a perfect storm of extraordinary factors coming together: fire, ice and criminal negligence.

“Nobody has investigated these marks before. It totally changes the narrative. We have metallurgy experts telling us that when you get that level of temperature against steel it makes it brittle, and reduces its strength by up to 75 per cent.

“The fire was known about, but it was played down. She should never have been put to sea.”

Titanic sank due to enormous uncontrollable fire, not iceberg, claim experts. Rachael Pells, The Independent, 3/1/2017
I share some of the skepticism of some of the below-the-line comments under this article, but there is no doubt that, even without the fire, the story of the Titanic is an interesting case study of history and narrative.

Information cannot be stored or communicated

Or rather, it is not information but data that is stored and communicated*.

Data are differences that have been given meaning (remember that data needs information).

Information is the trapezium at the end of the communication in which the meaning is extracted from the data. Or, better, the trapezium uses the data to create an information entity in a narrative.

So, what is on the SD on my phone is data, but data which someone/something somewhere imbued with meaning and which I intent to use as information. So I may reasonably talk about it as though it were information, but it is not actually information.

In working towards a unified narrative/theory of information, this distinction is important. You only get information where it is interpreted. Information is relative, in the sense that you only have information for something/someone - for a narrative. 

*Storage, BTW, is communication in time rather than space. Communication takes time, so communication in space is also communication in time. Unless we stay exactly at the same place, which is probably impossible, storage also involves communication in space. So there's only one sort of communication which is communication in space-time.

Post-truth politics; information and narrative

Post-truth has been named as the word of the year by Oxford Dictionaries. In terms of the narrative-information model, post-truth politics is when politicians who are presenting a particular narrative move beyond being highly selective in their choice of information to creating information which has no underlying data.

So narrative connects information, and information is constructed from a trapezium which, for convenience, is described here as converting an item of data (a difference) into an item of information (which makes a difference in the narrative). The trapezium is part of the narrative, so the process of converting data to information is also dependent upon the narrative. In politics, there is a pretence that, for a given purpose, if you have all the true data there is only one narrative: the true narrative. I say pretence because I doubt that anyone really believes it as baldly as that. However, this is how politicians' arguments line up: we want to achieve this (the purpose); the world is like this (the narrative built on the information) therefore there are no alternative: we need to do this.

If the information is true, the narrative is correct, so the argument proceeds. Post-truth politics doesn't bother with the truth of the information. It presents the narrative and creates the information needed to support it. Those opposed to the narrative cry foul! "You can't just make the information up: it has to be true." Well, there is a problem with requiring information to be true because information is always provisional, but even ignoring that, restricting narratives to those based on 'true' information doesn't get you very far.

The trouble is that there are almost limitless possibilities to choose from for the data, so, even if there is one true narrative to match the chosen data, there are endless narratives that may legitimately be constructed based on which choices are made. Given that situation, how can we chose one narrative over another? How we, as individuals, make the choice, is based on our prior beliefs: our prejudices, our past experiences, the community we share (our 'bubble', to use another current word). Beyond that is the question of what determines which narratives 'win out'. This is about recognising the hegemonic narratives and understanding where their hegemony comes from. The owners of the hegemonic narrative will defend their narrative by pointing to perceived flaws in competing narratives and either denying the data used in competing narratives or ignoring it and insisting on the superiority of the data they have chosen to their narratives. When competing narratives are being judged, much of the time the choice is based on which data you agree to recognise, rather than disputing the truth of the data.

So, looking back to the now-notorious EU leave campaign claim that "We send the EU £350 million a week. Let's find our NHS instead", putting it on the side of bus generated masses of publicity and, evidently, contributed to swaying enough of the voters to win the referendum. Most of the voters were not, realistically, in a position to make an informed assessment of the truth of that claim, or indeed most of the other claims on either side of the campaigns.

As argued in that previous post, the £350 million claim was sort-of true. The problem was that it was (IMHO - which is to say in my narrative!) wildly misleading, because: a) the information that it was converted to by the leave narrative was, questionable and b) choosing different data would support a very different narrative.

The truth or otherwise of the data, while important, is actually quite a small part of winning an argument. (Compare E.H.Carr's statement "To praise a historian for his accuracy is like praising an architect for using well-seasoned timber or properly mixed concrete in his building. It is a necessary condition of his work, but not his essential function".) What matters is the narrative, and the politician's ability to present the narrative.

Mainstream opinion pronounces itself shocked by post-truth politics and takes the moral high-ground, despising both those who present narratives built on falsehoods and those who believe them. But the real problem is the failure of alternative narratives. I referred to 'mainstream opinion' there, and that is part of the problem. Many people are rejecting the narratives of mainstream opinion because they feel let down, and they have been. And of course the concept of 'post-truth politics' is itself information created in a narrative of the mainstream opinion in order to discredit alternative narratives.

This post seems to be leading me towards sympathy for Donald Trump (as the most obvious  practitioner of post-truth politics). That is not what was intended, but sometimes narratives take you where they take you. (If you are an academic, anyway. A politician wouldn't let that happen.) And anyway none of this justifies the content of Donald Trump's politics, nor is it a defence of post-truth anything-at-all. What it is arguing is encapsulated very succinctly by something George Monbiot has said:
Those who tell the stories run the world. Politics has failed through a lack of competing narratives.
