Multi-level summaries – Part 2: The benefits of a new approach to non-fiction books

Are you a keen reader? If so, I would like to interview you to find out how you use non-fiction books to make progress in your work and/or personal life. More details here – www.makingideasvisual.com/interviews.

Introduction

The purpose of this article, which has been separated into two blog posts, is to show how multi-level summaries can make non-fiction books easier to understand, remember and act on. (Note 1)

Part 1 looked at the problems with the current structure of most non-fiction books. Part 2 now looks at how multi-level summaries can help to solve these problems.

Multi-level summaries

In Part 1, I explained that:

  • most non-fiction books have more of an implicit meaning structure
  • having an implicit meaning structures causes problems with cognitive load and retrieval practice.

The alternative to an implicit meaning structure is an explicit one and one way of providing them is through multi-level summaries.

To recap, an explicit meaning structure looks generically like this.

This structure can also be simplified into a pyramid.

Multi-level summaries show the big picture at different levels of detail in the book and how the different elements of content are connected to each other.

The most effective way to do this would be to create the following:

i) a whole book summary, showing how the book is structured and giving details of the key ideas and concepts
ii) individual summaries for each of the chapters, which show the structure of the chapter and provide a summary of the key ideas/concepts and the supporting topics in that chapter
iii) visual elements within individual chapters. Diagrams, tables, flowcharts, timelines and other visual elements are a very effective way of summarising complex ideas and most non-fiction books could use more of them.

There are potential variations to this:

i) If the chapters are divided into parts or the book is made up of very short chapters, it might be better to summarise linked chapters together.

ii) If a chapter has a great deal of content and is particularly dense, it might be better to add summaries within chapter sections as well.

It is important that each summary is contained on a single book page (or across a spread of two adjacent pages, if absolutely necessary) so that the relationship between the different content elements can be seen in a glance.

Multi-level summaries give readers the ability to zoom in and zoom out in a similar way to Google Maps.

Using Google Maps as an analogy

A good analogy for multi-level summaries is Google Maps in that it also provides the opportunity to view information at different levels of detail. (Note 4)

Let’s use Green Park in London as an example. One can choose a detailed view to see its position in relation to other landmarks in central London such as Westminster Abbey or St James’s Palace.

Zooming out to a wider view, Green Park can then be seen in relation to areas of London like Kensington, the City of London and Canary Wharf.

Zooming out even more, Green Park can be seen in the context of southern England and its location can be viewed relative to places like Bristol, Brighton and Ipswich.

While Google Maps has eighteen levels of detail from its most detailed view all the way out to a map of the world as a whole, most books will have just three or four levels of detail.

Multi-level summaries give readers the ability to zoom in and zoom out in a similar way to Google Maps. Readers can zoom in to focus on the detailed explanation in the text. They can then zoom out to the chapter summary to see how that detail fits into the context of the chapter. They can then, if they want, zoom out even further to the summary of the book to review the book’s key ideas.

The location of multi-level summaries in a book

Multi-level summaries would be located as follows:

i) there would be a summary of the whole book right at the beginning

ii) there would be a chapter summary at the beginning of each chapter.

iii) the book summary and all the chapter summaries would be repeated at the back of the book so that readers can consult them easily in sequence without having to page through the book looking for individual summaries.

Visual aspects of multi-level summaries

Summaries of books solely using text often look uninteresting and unappealing. So I think it is important that multi-level summaries use what Robert Horn calls visual language ie. a combination of words, images and shapes. (Note 5)

These visual elements can include:

  • diagrams to show the structure of the book and how different ideas connect to each other
  • boxes to separate text and show a hierarchy of importance
  • the use of colour
  • the use of diagrams, icons, tables, timelines and flowcharts to describe ideas
  • text itself being given a visual aspect – eg. capitalisation, text drawn as illustration etc.

There is a continuum between more text and more visual aspects. Different authors and different designers will plump for a different balance.

Sketchnoting, a field developed by designer Mike Rohde, has a great deal to offer multi-level summaries. Rohde defines sketchnotes as “rich visual notes created from a mix of handwriting, drawings, hand-drawn typography, shapes, and visual elements like arrows, boxes and lines”. (Note 6)

There is a great deal of innovation in this field at the moment. The sketchnoters and other visual thinkers whose work I particularly respect include Mike Rohde himself, Dave Gray, Dan RoamOliver Caviglioli, Rob Dimeo and Makayla Lewis.

Why multi-level summaries work

This is how multi-level summaries can help with the previously-identified problems about reading non-fiction books.

1. Getting started with a book

1.1 Finding it hard to get started

Problem: being confronted with hundreds of pages of text that will take many hours to get through can make it hard to get started.

Solution: the 20 minutes or so needed to read the book and chapter summaries provides an easy way in to starting a book.

2. Giving up on a book

2.1 Losing interest

Problem: many books are not finished because readers lose interest. A common experience is enthusiastically starting a book and then running out of momentum in the middle of Chapter 1 or 2.

Solution: the summaries allow readers to be much clearer about whether the book is going to be worth reading in full and to quickly identify which chapters of the book they are going to find most interesting. In addition, even if they only spend 20 minutes on a book, they will have got the big picture of the book and read the main arguments – in the same time that a reader not having access to multi-level summaries would take to get bogged down in the middle of Chapter 1 and give up.

3. Problems when reading a book

3.1 Drowning in detail

Problem: when books don’t have a clear structure or summaries of the main points, it’s easy for readers to get confused as they drown in too much detail and lose sight of what the key ideas are.

Solution: having multi-level summaries in addition to the text gives readers the flexibility to choose between detail and context. When they want to focus on detail, they can zoom in to find it in the text. When they’re getting confused, they can zoom out using the multi-level summaries to understand where that detail fits into the big picture.

3.2 Returning to a book after a break

Problem: it’s easy to forget the thread of a book’s argument after putting it down for a few days or a few weeks. Readers then either have to carry on reading superficially without remembering the outline of the book’s argument or spend time struggling to identify the key ideas from the pages they have already read.

Solution: multi-level summaries allow readers to refresh their memories about what they have previously read quickly. That means that they can easily pick up the thread of the book’s argument and therefore carry on reading productively.

4. Problems after finishing a book

4.1 Forgetting a book’s ideas

Problem: many readers complain about how little they remember of a book’s ideas even after they have spent hours reading it. That’s to be expected. Cognitive psychology teaches how easily facts and ideas are forgotten.

Solution: As previously explained, the concept of retrieval practice is increasingly recognised as a key part of helping both children and adults to remember more. When readers come across ideas they want to embed in their memory, having multi-level summaries allow readers to engage in retrieval practice easily.

In addition, having clear explanations of how the detail fits into the big picture can make the book’s ideas more memorable.

4.2 Struggling to work out what action to take

Problem: many books suggest new behaviours and strategies for the reader. If these new strategies and behaviours aren’t summarised adequately, it’s easy for a reader to move on to the next book without taking any action.

Solution: having adequate summaries allows readers to easily revisit the recommended strategies and behaviours once they have finished a book and then decide which, if any, they are going to put into practice.

4.3 Returning to a book

Problem: when readers want to remind themselves of the ideas in a book they have read in the past, a detailed re-read is often needed in order to get to grips with the book again.

Solution: having multi-level summaries means that readers can get an overview of the whole book in 15-20 minutes.

The benefits of using multi-level summaries

Examples of multi-level summaries

I have provided four examples of summaries. The three by myself comprise a book summary and an individual chapter summary from Cal Newport’s book Deep Work, and a summary of the Conclusion chapter of Tim Shipman’s book about the EU referendum campaign All Out War. I have also included a book summary by Sacha Chua of Josh Kaufman’s book The First 20 Hours.

I make no claim for my summaries being definitive ones. The authors would no doubt want to summarise their ideas in different ways. In addition, designers with much better design skills than mine will be able to produce nicer looking summaries.

However they provide an idea of what summaries can look like.

(i) a book summary created by myself of Deep Work: Rules for Focused Success in a Distracted World by Cal Newport (Piatkus, 2016).

This summary allows readers to find out in a short time some of the key information about the book:

  • it explains the main argument of the book, provides a definition of the main concept and explains the book’s main hypothesis
  • it provides a simple diagram showing the structure of the book
  • it provides short descriptions of the main arguments for the validity of deep work
  • it outlines all the different strategies for increasing deep work capability, grouped into the four categories.

(ii) an individual chapter summary created by myself of Deep Work: Rules for Focused Success in a Distracted World by Cal Newport (Piatkus, 2016).

This chapter summary goes into more detail about the six Work Deeply strategies. It allows readers to see at a glance a summary of each of the six strategies.

(iii) a summary of the Conclusion chapter from Tim Shipman’s book All Out War: The Full Story of How Brexit Sank Britain’s Political Class (William Collins, 2016).

For me, this particularly illustrates the power of visual summaries. Tim Shipman’s Conclusion is clearly written. However, in it, he provides a large number of reasons for Brexit, divided into a several categories. It is very hard to keep them all in mind. The visual summary allows the reader to easily see all the reasons grouped together on a single page and then makes it easier for the reader to start reflecting on them.

(iv) a book summary by Sacha Chua of Josh Kaufman’s book The First 20 Hours: How to Learn Anything Fast. This is very much on the visual side of the text-visual continuum.

Objections to multi-level summaries

Here are some of the objections to multi-level book summaries that I can envisage.

1) Dumbing down

Some people may consider multi-level book summaries a form of dumbing down. They may say that books have done a good job for centuries and that creating summaries is pandering to reduced attention spans and the laziness of readers.

I would reply that the current structure of non-fiction books reduces the intellectual engagement that many readers have with the books they read. Having summaries will reduce needless cognitive load and therefore increase their intellectual engagement.

2) Reducing complexity excessively

Some authors may be concerned that multi-level summaries won’t be able to communicate the complexity of their ideas and that therefore the subtlety of their arguments will be ignored by readers who focus just on the summaries. This is a fair point. An answer to this is to make sure that summaries refer to the additional complexities so that readers can follow these up.

3) Book detail being ignored

Authors may also be concerned that many readers will just look at the summaries and ignore their hard work on the text of the book. This may be the case for some readers but they would probably not have finished the book in the first place. The key will be to create interesting enough summaries that will make readers keen to go on to read the detailed explanation in the book.

4) Extra work for authors

Of course creating a multi-level summary is yet another task for an author to complete, even if they hand over the design work to someone else. However, hopefully the benefits of having readers who are more engaged with the book’s ideas will outweigh the burden of the extra work.

5) Making arguments clearer may expose any holes in an author’s argument

The current structure of books makes it easier for authors to hide gaps or weaknesses in their reasoning. Needing to be clearer about the steps in their argument won’t be to the taste of every author.

6) Unsuitability of some books

One category of non-fiction books not suitable for multi-level summaries are those that are mainly stories where the point is to follow the narrative and where having an overview of the book from the beginning would spoil the reading experience.

Benefits for authors

I do think multi-level summaries will have benefits for authors as well as the drawbacks mentioned above. Summaries will make it easier for readers to engage with an author’s ideas and, where applicable, to put the ideas into action.

How may multi-level summaries be developed in practice?

There are four ways in which multi-level summaries may be developed:

(i) authors. I hope that more authors will include multi-level summaries in their own books.

(ii) publishers. I hope that innovative publishers will begin to see the value of multi-level summaries and encourage authors to include them in their books.

(iii) readers. More and more readers are putting sketchnotes or visual summaries of books they have read online. In most cases it is just a book summary so it would be good to have more chapter summaries too.

(iv) book summary companies. Book summary companies tend to summarise the sequential structure of a book and not the different levels of detail. I think there is a big opportunity for innovative book summary companies to start producing multi-level summaries.

Using multi-level summaries in other areas

Multi-level summaries will be especially useful in two other areas – education and training. I will write about these areas in future blog posts.

Conclusion

I believe that multi-level summaries have an important role to play in making non-fiction books easier to understand, remember and act on.

I would be very glad to receive your feedback about the idea of multi-level summaries. Please send me an email through my Contact page.

Notes

1. An important inspiration for the multi-level summaries concept has been Frederick Reif’s work on the concept of hierarchical knowledge organisation (or hierarchically organised knowledge), which is outlined in Chapter 9 of his book Applying Cognitive Science to Education: Thinking and Learning in Scientific and Other Complex Domains (MIT Press, 2010).

I have also found the holographic/linear concept outlined in Ian Harris and Oliver Caviglioli’s book Think It – Map It! (Network Educational Press, 2003 – pp.28-33) very helpful in developing these ideas – as has been Oliver Caviglioli’s work in general on educational ideas and how they can be explained more effectively through visuals.

I have found Richard Koch’s work on the 80/20 Principle very valuable (The 80/20 Principle: The Secret of Achieving More with Less, Nicholas Brealey Publishing, 2003). His suggestion that 80% of the value of a book can come from 20% (or less) of the text started me thinking about the huge potential of summaries. [Return to article]
