In the past, scaling production may have been enough to be competitive. Now, the most competitive organisations scale change to continually improve customer centricity. How can we use what we’ve learned scaling production to scale change?
I presented a talk titled “Scaling Change” at the recent ThoughtWorks XConf, themed Scale. In the talk I explore the connections between scaling production, sustaining software development, and scaling change, using metaphors, maths and management heuristics. How can factories, home loans and nightclubs help us to think about and manage change at scale?
I contend that change is O(N2) due to the interaction of each new change with all previous changes. We could visualise this as a triangular matrix heat map of the interaction cost of each pair of changes (where darker shading is higher cost).
Therefore, a nightclub, where each new patron potentially interacts with all other denizens is an appropriate metaphor. Many of us can also relate to changes that have socialised about as well as drunk nightclub patrons.
The nightclub metaphor suggests the following management heuristics:
We take a variable cost hit for each change to help it play more nicely with every other change. This reduces the cost coefficient but not the number of interactions (N2).
We only take in the most valuable changes. Screening half our changes (N/2) reduces change interactions by three quarters (N2/4).
We arrange changes into separate spaces and prevent interaction between spaces. Using n spaces reduces the interactions to N2/n.
Like screening, but at the other end. We actively manage out changes to reduce interactions. Surrendering half our changes (N/2) reduces change interactions by three quarters (N2/4).
Surprise! Managing work in a large organisation is a lot like keeping your belongings in check at home.
Get it wrong at home and you have mess and clutter. Get it wrong in the organisation and you have excessive work in progress (WIP), retarding responsiveness, pulverising productivity, and eroding engagement.
Reading Marie Kondo’s The Life-Changing Magic of Tidying Up (Amazon), I was struck by a number of observations about tidying personal belongings that resonated with how individuals, teams and organisations manage their work.
First, reading TLCMOTU helped me tidy my things better. Second, it reinforced lean and agile management principles.
I won’t review the book here. However, because I think tidying is something that everyone can relate to, I will compare some of KonMari’s (as Marie Kondo is known) explanations of the management of personal belongings with the management of work in organisations. The translation heuristic is to replace stuff with work, and clutter with excessive WIP, to highlight the parallels.
On the complexity of work storage systems
This key passage is where I started; the rest fell into place from here.
Most people realise that clutter is caused by too much stuff. But why do we have too much stuff? Usually it is because we do not accurately grasp how much we actually own. And we fail to grasp how much we own because our storage methods are too complex.
Organisations typically employ complex storage methods for their work: portfolio and project management systems with myriad arcane properties, financial and accounting constraints, and restricted access to specialists who embrace the complexity.
Instead of discarding work so that simple portfolio storage will suffice, organisations invent ever-more complex systems to stuff work into storage maximise utilisation of capacity, which consequently hides the extent of the work.
Thus, we fail to grasp how much work is held in the organisation, and the result is excessive WIP, inflating lead times and reducing productivity, and leaving workers disengaged. Simplifying the storage of work – as simple as cards on a wall – shows the work we hold, and allows us to better manage WIP for responsiveness and productivity.
On making things visible
KonMari observes that you cannot accurately assess how much stuff you have without seeing it all in one place. She recommends searching the whole house first, bringing everything to the one location, and spreading the items out on the floor to gain visibility.
Making work visible, in one place, to all stakeholders is a tenet of agile and lean delivery. A great resource for examples and ideas is Agile Board Hacks. You may need to search extensively within the organisation to discover all the work, but understanding of the sources of demand (as below) will guide you.
KonMari observes that items in one category are stored in multiple different places, spread out around the house. Categories she identifies include clothes, books, etc. She contends that it’s not possible to assess what you want to keep and discard without seeing the sum of your belongings in each category. Consequently, she recommends thinking in terms of category, rather than place.
Understanding sources of demand is critical to managing WIP, especially BAU requests coming from multiple stakeholders. We need to work with sources of demand that are pulling work from our team or organisation, such as customers, business units, etc, rather than internal constructs we have used to store WIP, such as projects, teams, etc. Using projects or teams to organise work, we can’t make an accurate assessment of which work to keep and which to discard; we can only do this if we can see the entire demand from each source in one place.
The best way to choose what to keep and what to throw away is to … ask: ‘Does this spark joy?’ If it does keep it. If not, throw it out.
We may ask of each piece of work: ‘Is this work valuable?’ ‘Is it aligned to the purpose of the organisation?’ ‘Is it something customers want?’ If it is, keep it. If not, throw it out.
KonMari demonstrates why this is effective by taking the process to its logical conclusion. If you’ve discarded everything that doesn’t spark joy, then everything you have, everything you interact with, does spark joy.
What better way to spark joy in your people than to reduce or eliminate work with no value and no purpose?
On discarding first
KonMari observes that storage considerations interrupt the process of discarding. She recommends that discarding comes first, and storage comes second, and the activities remain distinct. If you start to think about where to put something before you have decided whether to keep or discard it, you will stop discarding.
Prioritisation is the act of discarding work we do not intend to pursue. Prioritisation comes first, before implementation considerations. Scheduling, given estimates and other constraints, is the process of deciding which “drawers” to put work in once priority is determined.
On putting things away
KonMari observes that mess and clutter is a result of not putting things away. Consequently she recommends that storage systems should make it easy to put things away, not easy to get them out.
Excessive WIP may also be caused by a failure to rapidly stop work (or perceived inability to do so). Organisational approaches to work should reduce the effort needed to stop work. For instance, with continuous delivery, a product is releasable at all times, and can therefore be stopped after any deployment. Work should be easily “stoppable” in preference to easily “startable”. (This could also be framed as “stop starting and start finishing”.)
Further, while many organisations aim for responsiveness with a stoppable workforce (of contractors), they should instead aim for a stoppable portfolio, and workforce responsiveness will follow.
On letting things go
A client of KonMari’s comments:
Up to now, I believed it was important to do things that added to my life … I realised for the first time that letting go is even more important than adding.
However, KonMari also observes that, beyond the mechanics of managing stuff (or work), there is a psychological cost of clutter (or excessive WIP). Her clients often report feeling constrained by perceived responsibility to stuff that brings them no joy. I suspect the same is true in the organisation: we fail to recognise and embrace possibilities because we are constrained by perceived responsibilities to work that ultimately has no value.
Imagine if we could throw off those shackles. That’s worth letting a few things go.
The path to good design is bumpy, as we will demonstrate with four teapots. (Yes, teapots. Teapots are a staple of computer science and philosophy.)
The path to good design matters, because if you are trying to build a design capability, the journey will be smoother if you understand that the path is bumpy.
Leaders who appreciate the bumpy path can facilitate far greater value creation and support a more engaged group of workers.
What is design?
Design is an activity, but also a result: the specification for a product (service), which determines how it is made or delivered.
Performance is a measure of how a product actually functions, for a given task in a given context. Performance in the broadest sense includes emotional responses, static and dynamic physical characteristics, service characteristics, etc. For simplicity, let’s measure performance in monetary terms; eg. lifetime economic value.
Design is important as an activity and a result, because it is the prime determinant of performance that is within your control.
The smooth path
Consider the distinctive teapot from the cover of Don Norman’s Design of Everyday Things, where the handle – instead of opposing – is aligned with the spout.
We know a thing or two about teapots, so we assume this design has very poor performance!
However, we also assume that a traditional design with handle opposed to the spout produces the best performance.
We can plot our smooth model of how performance varies as a function of the angle between spout and handle.
And it’s pretty clear how to find the best design. The more opposing the handle and spout, the better the performance, the more value created, and hence the better the design.
The first bump in the path
However, this model is broken. We can’t interpolate smoothly (linearly) between design points, as demonstrated by the Japanese yokode kyusu, which features a handle at right angles to its spout, to extract every last drop of tea.
With this new insight, and a further assumption that handles in between the points we’ve plotted (eg, 45 degrees) are much worse due to awkward twisting motions when pouring, we can draw a new model, which is already much less smooth.
What’s interesting about this landscape is that most design variants perform pretty poorly, and you must be close to a good design to find it. If you didn’t have the insight into teapot performance that we have assumed – if you had only tested performance at the awkward angles, and you had assumed smooth behaviour in between – you would likely miss the best designs and leave significant value on the table.
So, this is the first lesson of the bumpy path to good design. We need to explore the performance of multiple design variants, and understand that small changes in design can have enormous impacts on performance, to be confident we are approaching our potential to create value.
So far, we have only explored the impact of one design variable, but for any product we have effectively infinitely many design variables (if we can just conceive them). For instance, the handle of a teapot could also be on top, but we could also consider the shape, material, fixtures, etc. Then we could move beyond the handle to the design of the rest of the teapot!
Now consider the design and delivery of digital products and services. Constraints do exist, but infinite design variants still exist within those constraints. Further, like the rolled up dimensions of string theory, there are extra dimensions of design that are easy to miss, but once discovered can be expanded and explored to create ever more value.
The first lesson
How do leaders get this wrong? By failing to encourage the exploration of a sufficient number of design variants, and by failing to encourage the exploration of minor changes that have outsize impact.
As a leader, you must be prepared to carve out time and space, embrace uncertainty and ambiguity, and bring creativity, compassion and patience to the exploration process. As important as this is to creating value, it is also key to maintaining the engagement of teams involved in or interacting with design.
I’m often told that exploration feels inefficient. Or, rather, felt inefficient. The distinction is importation. Hindsight bias distorts the reality that before starting an exploration into a sufficiently bumpy landscape, we simply cannot know what we will find. So how do we measure efficiency of exploration? Certainly not by how quickly we arrive at a design, or by how many designs are discarded. Should we even measure efficiency of exploration? That is a better question. We should focus on net value creation, and do enough exploration to mitigate the risk that we are leaving significant value on the table.
This design sensibility, however, may not be apparent to the whole team. Designers will be frustrated being managed to a smooth path, while others who perceive the challenge to be simple may become frustrated when the bumpiness is allowed to surface. The team’s various activities may have different cadences that sometimes align, and sometimes don’t. This can create friction and dissatisfaction in teams. Some functional conflict is healthy in this regard, but as a leader, you must support and enable a team to focus on what it takes to create value.
The second bump in the path
I have used word “assume” liberally and deliberately above. I have assumed a large number of things about the tasks that users of the teapots are seeking to achieve, and the broader contexts of use. I have further assumed that my readers share a traditional western notion of teapots and their use. I have done this to keep simple – I hope – the explanation of the first bump.
But “assume” is at the root of the second bump. During product development, we can’t assume performance, we must test designs with users engaged a task in a context. We may take shortcuts by prototyping, simulating, etc, but we must test as objectively as possible, for a meaningful prediction of a product’s performance, and potential to create value.
In a bumpy design landscape, poor predictions of actual performance carry significant opportunity cost.
(Note also that during the development of a typical digital product/service, we are typically iteratively discovering the task and the context in parallel.)
We assumed, with our teapots above, that a spout aligned with the handle would lead to poor performance, but we didn’t test it (with a minor tweak in a hidden dimension). If we’d tested this traditional oriental design (as UX Designer Mike Eng did), we would have discovered that, for the task of serving oneself, in a solitary context, the aligned handle actually produces superior performance.
I was surprised to find this teapot design existed when I stumbled upon the post from above. I suspect this teapot design has a specific name or an interesting story behind it, but I haven’t been able to track it down. However, it serves as an excellent demonstration that the best design paths are bumpy.
The second lesson
The second lesson is that assumptions about performance, task and context hide the inherent bumpiness in design. As a leader, you must recognise and challenge assumptions, encourage the testing of designs under the correct conditions, and appreciate that our understanding of task and context may evolve with testing.
There are many resources that discuss lightweight and effective approaches to UX research and testing; you could do worse than to start here.
We have discussed two major value creation activities in design:
Exploration and consequent discovery of performant designs
Testing and consequent selection of more performant designs
But these activities are overlooked or de-prioritised with a smooth mindset. While there is uncertainty, ambiguity and friction along the path, and sometimes progress is difficult to discern, as a leader, you must embrace the bumps because – if you are in the business of creating value – there is no smooth path to good design.
Culture is often difficult to define, and culture change even more so – what concrete actions do we need to take to change a culture?
Despite this apparent difficulty, it is possible to spend an hour or two with a group, and leave with consensus on practical actions for culture change.
This exercise achieves that by make culture change something concrete. We look to the questions we ask everyday as reinforcing values and thus being drivers of culture. Then we challenge ourselves to find better questions, and explore what it will take to adopt those better questions in our specific context.
Questions driving culture
Let’s keep our definition of culture really simple: the sum of our everyday behaviours as a group.
To give an example: typically, you and your colleagues juggle many tasks at once. Multitasking is part of your culture.
What is driving this behaviour though? One strong driver is the questions that are asked in your group. For instance, in this environment, you probably find people explicitly asking something like “can you take this on?” The multitasking behaviour is a natural response to that question. Especially if all parties are, consciously or otherwise, implicitly asking themselves “how do we get everything done?”
Now let’s assume that you want to change your multitasking culture to one where people limit their work in progress to become more productive overall.
Making change more concrete
To change the behaviour, we can look for the driving questions and change those.
For instance, we might aim to change “how do we get everything done?” to “how do we do a great job of the most important things?”
And that is the heart of the change. If everyone is asking themselves, consciously or otherwise “how do we do a great job of the most important things?”, their behaviours will follow that question. In this case (and with training and support as required), we expect they will try to identify priorities, understand success and deliver on that before moving on to the next thing. People can helpfully answer “no” to the old question “can you take this on?”, but more importantly, that question will no longer be asked as frequently, because it will cease to make sense.
However, that’s still not as concrete a recipe as we would like. The exercise (below) helps us get down to the concrete actions required in a given context to change one driving question to another.
Before we go any further, though, a reminder that questions do not exist in isolation, and that we must tackle consistent set of questions simultaneously:
Today’s orthodoxy has institutionalised a set of internally consistent but dysfunctional beliefs. This has created a tightly interlocking and self-reinforcing system, a system from which it is very difficult to break free. Even when we change one piece, the other pieces hold us back by blocking the benefits of our change. When our change fails to produce benefits, we revert to our old approaches.
Donald G. Reinertsen, The Principles of Product Development Flow
This exercise can be run with the group whose culture we are looking to change.
At the end of the exercise, you will have a list of concrete actions that can be taken to change driving questions, and will have identified potential blockers to plan around.
Observe the group and its behaviours
Identify instances of counter-productive behaviours
Analyse these behaviours to propose driving questions
Pair current, undesirable driving questions with new, desirable driving questions
Find examples to illustrate why each question should change
You should have something like the table below:
The exercise can then be run as follows:
Discuss the premise of changing culture by changing questions
Share your first example of a pair of driving questions, and the instance of the behaviour (this should be an instance widely understood and accepted by the group)
Work through the other question pairs in your list, and ask the group to come up with examples themselves. They will generally do so enthusiastically! It’s unlikely, but if they don’t, you have your prepared examples to fall back on.
Because you won’t be able to solve everything in this session, prioritise as a group (through dot voting, etc) the question pairs to focus on (no more than 3 for the first session). Allow 30 mins to 1 hour to get to this point.
Now for each question pair, run an “anchors and engines” exercise to identify – in the group’s context – the potential blockers (“anchors”) and the supporting factors or concrete actions (“engines”). Take 15-30 minutes per pair. Synthesise individual contributions into themes.
You now have a set of concrete actions to support, and real issues that might hinder, the type of culture change you are seeking to achieve. It might look something like:
Of course, effort remains to make this change happen, but it can be directed very precisely, and that is valuable when dealing with culture.
It’s a self-guided audio tour of historic sites in Broome, Western Australia, including beautiful stories told by locals. Nyamba Buru Yawuru developed the concept, curated the media, engaged local stakeholders, and were product owners for the app.
This work was exciting for its value to the Broome and Yawuru community, but also because it was an opportunity to innovate under the constraint of building the simplest thing possible. The simplest thing possible was in stark contrast to the technical whizbangery (though lean delivery) of my previous app project – Fireballs in the Sky.
I had fun working on the interaction and visual design challenges under the constraints, and I think the key successes were:
Simplifying presentation of the real-world and in-app navigation as a hand-rolled map (drawn in Inkscape), showing all the sites, that scrolls in a single direction.
Hiding everything unnecessary during playback of stories, to allow the user to focus on the place and the story.
Playback control behaviour across sites and the main map.
Not succumbing to the temptation to add geo-location, background audio, or anything else that could have added to the complexity!
I helped organise this event with assistance from sponsors ThoughtWorks and Curtin University (among numerous other generous sponsors). It was a great event, with important and challenging problems presented, innovative solution concepts delivered, and new relationships formed between individuals and organisations in health and technology.
We focussed on curated problems for this event, approaching a large number of potential “problem owners” to recruit those with the most appropriate challenges for the weekend hackathon format. We then worked with the problem owners to shape their challenges and pitches for the “ideas market”. This was a very substantial effort (primarily by the fabulous Diana Adorno) in the lead-up to the weekend, but the well-formed problems were key to the success of the hack.
We attracted a diverse set of participants, with skills ranging from design, to software development, to data science, and these individuals organised themselves into teams around the problems most suited to their collective skill set. As organisers, we made only one substitution to balance teams.
We started with fewer participants than expected, because the drop-off rate from registrations was substantially higher (50%) than previous years at other sites (30%). However, attrition over the weekend was virtually zero, as the participants were uniformly enthusiastic and energised by their challenges.
The ideas market built great energy around the challenges and the potential for the weekend. We posted the challenges around the room prior to the event. Then the problems owners took turns to pitch in just 2 minutes each from their challenge posters. The pitches were clear and concise, and the cumulative effect was really energising. When the pitches were done, participants had time to walk the room, seek more information from problem owners, and organise their own teams.
Coaching and regular check-ins on team progress helped keep the teams focussed on solving key problems and having a demonstrable product at the end of the weekend. No team failed to showcase. However, we had feedback that access to more coaching would have been valuable.
The venue at Curtin University Chemistry Precinct was ideal, with team tables, breakout spaces and bean bags, and surrounded by gardens. However, it was the only Health Hack venue not in the CBD of the host city, and this may have presented transport challenges (though we didn’t collect any data on this). The plan at the time was to rotate the venue through various supporting institutions in future years.
Food trucks and coffee vans were a great way to service participants! Although it required some coordination ahead of the event, and may not be possible in CBD sites, it was very easy on the weekend, and lots of fun.
Here are slides from my talk at LASTconf 2015. The title is “Bring Your A-Game to Arguments for Change”. The premise is that there are different types of arguments, more or less suited to various organisational and delivery scenarios, and the best ones have their own agency. In these respects, you can think of them like Pokemon – able to go out and do your bidding, with the right preparation.
The content draws heavily from ideas shared on this blog:
Why a nightclub? Well, it’s a better model than a home loan. I’m talking here about technical debt, the concept that describes how retarding complexity (cost) builds up in software development and other activities, and how to manage this cost. A home loan is misleading because product development cost doesn’t spiral out of control due to missed interest payments over time. Costs blow out due to previously deferred or unanticipated socialisation costs being realised with a given change.
So what are socialisation costs? They are the costs incurred when you introduce a new element to an existing group: a new person to a nightclub, or a new feature into a product. Note that we can consider socialisation at multiple levels of the product – UX design, information architecture, etc – not just source code.
Why is socialisation so costly? Because in general you have to socialise each new element with all existing elements, and so you can expect each new element you add to cost more than the last. If you keep adding elements, and even if each pair socialises very cheaply, eventually socialisation cost dominates marginal cost and total cost.
What is the implication of poor socialisation? In a nightclub, this may be a fight, and consequent loss of business. In software, this may be delayed releases or operational issues or poor user experience, and consequent lack of business. If you build airplanes, it could cost billions of dollars.
What does this mean for software delivery, or brand management, or product management, or organisational change, or hiring people, or nightclub management, or any activity where there is continued pressure to add new elements, but accelerating cost of socialisation?
Well, consider that production (of stuff) achieves efficiencies of scale by shifting variable cost to fixed for a certain volume. But software delivery is not production, it is design, and continuous re-design in response to change in our understanding of business outcomes.
Change can be scaled by shifting socialisation costs to variable; we take a variable cost hit with each new element to reduce the likelihood we will pay a high price to socialise future elements. Then we can change and change again in a sustainable manner. We can also segment elements to ensure pairwise cost is zero between segments (architecture). But, ideally, we continue to jettison elements that aren’t adding sufficient value – this is the surest way minimise marginal socialisation cost and preserve business agility. We can deliver a continuous MVP.
So what does this add to the technical debt discussion? All models are wrong; some are useful. Technical debt is definitely useful, and reaches some of the same management conclusions as above.
For me, the nightclub model is a better holistic model for product management, not just for coding. It is more dynamic and reflective of a messy reality. Further, with an economic model of marginal cost, we can assess whether the economics of marginal value stack up. Who do we want in out nightclub? How do we ensure the mix is good for business? Who needs to leave?
What do you think?
Postscript: The Economic Model
We write total cost (C) as the sum of fixed costs (f), constant variable cost per-unit (v) and a factor representing socialisation cost per pair (s):
\[ C = f + vN + sN^2\]
Then marginal cost (M) may be written as:
\[ M = v + 2sN \]

Not online fitness shopping. Not the brogrammer pumping iron. This is a brief discussion of Antifragile – the latest book by Nassim Nicholas Taleb – and relevant insights for software delivery or other complex work.
This isn’t meant to be an exhaustive exploration of the topics. It’s more a join-the-dots exercise, and it’s left up to the reader to explore topics of interest.
Antifragile is a word coined by Taleb to describe things that gain from disorder. Not things that are impervious to disorder; the words for that are robust, or resilient. Of course, things that are harmed by disorder are fragile. Consideration of the fragile, the robust, and the antifragile leads Taleb in many interesting directions.
Fragile, Robust, and Antifragile Software
A running software program is fragile. It is harmed by the most minor variations in its source code, its build process, its dependencies, its runtime environment and its inputs.
But software is eating the world. The global software ecosystem has grown enormously over an extended time – time being a primary source of variation – and hence appears to be antifragile. How do we reconcile this apparent paradox?
Here is a grossly simplified perspective.
First, software code can evolve very quickly, passing on an improved design to the next generation of runtime instances. In this way, tools, platforms, libraries and products rapidly become more robust. However, human intervention is still required for true operational robustness.
Second, humans exercise optionality in selecting progressively better software. In this way, beneficial variation can be captured, deleterious variation discarded, and software goes from robust to antifragile.
So – as fragile parts create an antifragile whole – runtime software instances are fragile, but fragile instances that are constantly improved and selected by humans create an antifragile software ecosystem. (If software starts doing this for itself, we may be in trouble!)
Some Delivery Takeaways
Yes, I know that’s an oxymoron. Nonetheless, here are some of my highlights. It’s a while now since I read the book, and I might add to this in future, so don’t take it as the last word.
The idea of “dumbbell”/”barbell” risk management is that you place your bets in one of two places, but not in between. You first ensure that you are protected from catastrophic downside, then expose yourself to a portfolio of potentially large upsides. In such cases, you are antifragile.
If, instead, you spread yourself across the middle of the dumbell, you carry both unacceptably large downside exposure and insufficiently large upside exposure. In such cases, you are fragile.
For me, “dumbbell delivery” is how we counter insidious elements of the construct of two-speed-IT (insidious because no one has ever asked to go slow, or asked for high risk as the alternative). We ensure any project is as protected as possible from catastrophic downside – by decoupling the commission of error from any impact on operations or reputation – and as exposed as possible to potentially large upsides – by providing maximum freedom to teams to discover and exploit opportunities in a timely manner.
Those who intervene in complex systems may cause more harm than good. This is known as iatrogenics in medicine. To manage complex systems, removing existing interventions is more likely to be successful than making additional interventions, as each additional intervention produces unanticipated (side) effects by itself, and unanticipated interactions with other interventions in tandem. Via negativa is the philosophy of managing by taking things away.
Software delivery, and organisations in general, are complex in that they are difficult to understand and respond unpredictably to interventions. What’s an example of an intervention we could take away? Well, let’s say a project is “running late”. Instead of adding bodies to the team or hours to the schedule, start by trying to eliminate work through a focus on scope and quality. Also, why not remove targets?
Big Projects, Monolithic Systems
Anything big tends to be fragile. Break it into smaller pieces for greater robustness. Check.
Waterfall and Agile
Waterfall done by the book is fragile. Agile done as intended is antifragile.
Forcing natural variation into pre-defined, largely arbitrary containers creates fragility. Velocity commitments and other forms of management by performance target come to mind.
Skin in the Game
Of course, anyone making predictions should have skin in the game. On the other hand, Hammurabi’s code is the converse of the safe-to-fail environment.
The Lindy Effect on Technology lifespan
The life expectancy of a technology increases the longer it has been around. Remember this the next time you want to try something shiny.
Phenomenology and Theory
Phenomenology may be superior to theory for decision-making in complex work. Phenomenology says “if x, then we often observe y“. Theory says “if x, then y, because z“. Theory leads to the illusion of greater certainty, and probably a greater willingness to intervene (see above).
