Spotting psychological inertia and breaking out of it
Enlisting the help of Smart Little People
Using Size–Time–Cost thinking
If you want to learn how to think creatively on demand, it’s important to understand what stimulates and what gets in the way of creativity.
We all fall into a mental rut from time to time, and in TRIZ we call this developing psychological inertia, which is one of the biggest blocks to creativity. All of the TRIZ tools help you challenge your psychological inertia, but before you can get out of your mental rut, you have to realise you’re in it.
Psychological inertia is the TRIZ term for being stuck in a particular way of thinking. TRIZ gives you methods for stimulating your creativity as well as ways of examining your thinking, challenging your assumptions and thinking creatively. The TRIZ tools help you look at and understand situations in a new way and to find creative solutions to your problems.
In this chapter I also outline two powerful, standalone creativity tools in detail: Smart Little People and Size–Time–Cost. Both Smart Little People and Size–Time–Cost illustrate one of the fundamental TRIZ philosophies in action: start by thinking in extremes and then work out how to bring your ideas back to reality (more on this in Chapter 9). The logic behind this approach is that going to a far-out, wacky place restructures your view of the problem, allowing you to break out of psychological inertia and test constraints to find out whether they’re real or not. You gain a new perspective on your issue and can think of new ideas without worrying about whether or not they’re practical.
Psychological inertia is a term invented by engineers to describe a particular type of problematic thinking; it uses the language of physics to describe a psychological phenomenon. In normal language ‘inertia’ means doing nothing, but in physics this term refers to the resistance of an object to change – in motion, speed or direction.
An object can be moving, and will keep going in the same direction, at the same speed, unless another force acts upon it. This is a very insightful way of describing thinking, because getting stuck can mean your thinking is active but in a rut – you can’t change direction.
You can fall into a mental rut because you’re making assumptions, which limit your thinking. And the first rule of assumptions is that you don’t know you’re making them.
The first step to getting out of your mental rut is realising you’re in it. This is why so many of the TRIZ creativity tools challenge your view of problems, forcing you to take a step back and re-examine the situation. You do a reality check by continually asking yourself if you have psychological inertia; the answer is usually yes. For all of us!
Don’t feel embarrassed about your psychological inertia and making of assumptions; these happen to the best of us. Without assumptions, comedians would have a hard time making a living because setting up and shattering them is the basis of many jokes. Here are some examples:
These jokes are funny because the punchline’s a surprise – and it’s a surprise because the comedian telling you the joke has deliberately set up your assumption about the meaning of a word or phrase and then subverted it.
When people talk about ‘insight’ in problem solving and the ‘aha!’ moment when they generate a really clever solution, what they’re usually describing is the realisation they’re making assumptions and the point at which they think of a solution that breaks their psychological inertia. That moment feels fantastic and as enjoyable as laughing at the punchline to a really funny joke. You can experience that feeling and generate those kinds of solutions systematically by challenging your psychological inertia and applying the TRIZ creativity tools to generate clever solutions.
Every time someone says no, he’s indicating he may be experiencing psychological inertia. ‘You can’t do that because … it’s too expensive/it takes too long/it’s too hard’ are indicators that the person saying these things is making assumptions about the scope of possible solutions. He’s also probably making assumptions about the specific way in which to put a particular solution into practice. You need to start with what you want and not make the assumption that it’s going to be hard to get – this attitude could be psychological inertia at work. Just because you don’t know how to do something, doesn’t mean it’s necessarily hard to do. It may be very easy for someone else – and very easy indeed to find out either way.
Many types of psychological inertia exist, including your
Although I’m being quite negative about psychological inertia, it happens for a reason. Psychological inertia is useful on a daily basis because its efficiency enables you to do tasks quickly.
Psychological inertia is necessary to get you out of the house every day. When you’re getting dressed, for example, you don’t need to think about it too hard, which is good because you can get dressed fast. When you put on shoes that require lacing, you don’t think to yourself, ‘How am I going to do this today?’ Instead you just do it, quickly. In fact, thinking about automatic things consciously and trying to change them can feel uncomfortable – try putting your trousers on starting with the other leg to the one you usually begin with. Your habits become a kind of psychological inertia – and habits are hard to break.
Some tasks require explicit learning that then becomes second nature. When you first learn to drive, for example, you have lots to learn: starting with physical tasks such as how much pressure you need to apply to the pedals and how much to move the steering wheel to get the car to do what you want. You have to learn how to do these things first, before you can take on higher level problems such as merging with traffic and monitoring and predicting what other road users are likely to do. Initially, you have to think about these tasks consciously, but as you develop real skill, so you begin to drive automatically. In fact, if you later try to teach someone else how to drive, it can be remarkably difficult to remember what it is that your brain now does automatically.
When you’re problem solving, your professional experience can act in the same way: because you’ve developed expertise, your brain can be efficient, taking shortcuts in thinking according to what you’ve seen in the past. This is the basis of your professional intuition; your experience has become second nature and unconscious. As a result, your brain has seen a particular type of problem many times before and works out the most likely, useful solutions to it without conscious thought. Unfortunately, your professional intuition is unlikely to lead you to creative solutions; it’s hard-wired to repeat past success. When you’re looking for new creative thinking, your expertise can thus get in the way.
The point to bear in mind is that you’re supposed to develop psychological inertia. It helps you think and behave efficiently, which frees up mental space and energy to think about higher level problems, and solve routine problems efficiently. However, psychological inertia can be a habit that’s hard to break. It can load you down with misplaced assumptions or biases that direct your thinking in unhelpful directions and get in the way of creative thinking. Fortunately, TRIZ can help you overcome psychological inertia.
So you’ve realised that you’re experiencing psychological inertia and you want to do something about it. But what? You explicitly look for and apply different ways of thinking: you are creative on purpose.
One really important aspect of creative thinking is allowing yourself to think of all solutions without judgement. Most creativity approaches say much the same thing, including the rules of brainstorming (covered in Chapter 3).
One technique for making yourself view all ideas non-judgementally is to name them bad solutions, which simply acknowledges that they’re imperfect and can be improved upon. Your, or someone else’s, idea is a bad solution to the problem at hand; it’s a top-of-the-head idea that can be improved and developed by you and others.
Bad solutions help you generate more ideas individually and as a team. Always capture all solutions as they occur to you, and put them in a ‘Bad Solution Park’. Never squash any solutions, no matter how wacky they are (you can discard them later, if necessary).
If you have an idea, write it down. If you think it’s completely impractical, you may just be experiencing psychological inertia!
Applying explicit TRIZ tools to shape your thinking on an issue will force you to look at it from a new angle, and also uncover the existence of psychological inertia and help overcome it. The trick is to allow this to happen – accept that your current view may be blinkered by assumptions and take a few minutes to explore it with a different way of thinking. Basically, you need to suspend disbelief or judgement for a time. All TRIZ tools challenge psychological inertia and stimulate your creativity in different ways so that you can apply it to your thinking throughout the problem-solving process.
That said, 13 of the TRIZ thinking tools and approaches can be applied as specific creative thinking tools:
All the TRIZ tools shown in this list can be used as simple creativity tools to help you restructure your view of the problem, stimulate your thinking to define your problem differently and find new answers.
Smart Little People is a TRIZ thinking tool developed from the observation of clever and creative people at work.
When Altshuller and the early TRIZ community were first teaching TRIZ, they gave engineers and scientists problems to solve and asked them to talk aloud as they tackled them. They observed that sometimes people put themselves inside the problem; for example, if someone was looking at a leaking pipe he may say, ‘If I was in the pipe, I’d cover the hole with a patch’. Altshuller noticed that when people put themselves inside the problem, they often came up with very inventive solutions. He thus developed a tool for creative thinking based on empathy, explicitly asking people to imagine themselves inside the problem area, wherever that may be – even if this was a physical impossibility in real life. What he then saw was that, while people came up with inventive solutions, if anyone else suggested things that would hurt or damage their imaginary selves inside the problem area (for example, using boiling water or acid), these solutions were rejected. The problem solvers experienced a form of psychological inertia: they wanted to protect their imaginary selves.
This problem was resolved by getting people to imagine a crowd of Smart Little People rather than just one person. In this situation they were able to imagine people being helpfully involved in solving the problem, but don’t reject ‘dangerous’ solutions in case they get hurt. With an infinite number of people who can solve the problem, it doesn’t matter if a few thousand get destroyed.
Smart Little People provides you with a method to model your problem – and generate solutions – conceptually.
Smart Little People is a short-circuit around the Prism of TRIZ (see Chapter 6). You take a real-world, detailed problem and describe it as if the whole problem zone was made up of Smart Little People:
Smart Little People is a very good tool for modelling any kind of real-world problem. I’ve encountered it used to model oil leaks in an engine (showing where and how the naughty little people escape and what can be done to prevent it); growing crystals for use in semi-conductors (showing how the molecular bonding is happening and where imperfections may be occurring); and medical devices (showing how a needle parts skin and exactly how the drug enters the patient’s system) – to name but three.
Smart Little People helps bring very fresh thinking to a problem because you literally step out of the real world into an imaginary universe where you model a situation using teeny tiny people. It can generate quite wacky, silly thinking and, as a result, can be a lot of fun. For this reason, sometimes very serious people can at first be a little alarmed by the whole idea, but this aspect of the tool is actually quite important.
Studies demonstrate that creative thinking is often enhanced by a positive mood: if you’re joking and laughing as you work on a problem, you’re more likely to generate creative and inventive ideas than if you’re all being terribly serious. A positive mood encourages flexible thinking, making novel and unusual connections between things and more fluid idea generation. However, in addition to the fun, Smart Little People is a structured and systematic way of helping you approach your problem from a new direction, and then to generate solutions. Because you’re working in a pretend situation with imaginary people, it’s easier to think of solutions to problems because your thinking doesn’t have to be realistic and, as a result, is freer and more creative.
Traditional garlic presses are easy to use but fiddly and difficult to clean. You want to produce a garlic press that is easier to clean.
First, draw a picture of the system you want to improve or the problem area. Doing so helps you clarify what you want to look at and what you need to cover. Second, take your system and model how it functions using Smart Little People: model both what it does and all the problems that are occurring. Figure 7-1 shows one way in which your garlic press could be imagined as Smart Little People.
Third, when you’ve modelled all the problems as Smart Little People, think of ways in which useful little people could come along and help. What could they do to solve the problems? Model conceptual solutions as little people doing useful things: some examples are shown in Figure 7-2.
During this step, don’t worry too much about how your potential solutions become a reality. Instead, focus on how the little people could help. Figure 7-2 provides some examples:
The fourth step is to work out how these ideas could be turned into real-world solutions.
When you’ve modelled your conceptual solutions with Smart Little People, you then have to work out how these could translate into real-world solutions. Your experience and expertise become useful at this point and you focus your search for practical solutions on a number of different specific functions that you’ve identified through the actions of your Smart Little People.
For the garlic press example shown previously in Figure 7-2, you take each of your conceptual solutions and work out how it could become a reality:
When you use Smart Little People, you move through the Prism of TRIZ in the manner shown in Figure 7-3. You start with a real-world problem, and translate it into a conceptual problem, described as little people. Then you imagine a conceptual answer, and have to translate it into something real. The last stage in moving around the Prism of TRIZ connects your conceptual, imaginative answer with your real-world experience and expertise to help you create eventual, real-world solutions.
Generally in life you have a good idea of the practical limits of what you can do, what you can achieve and what you’re looking for. These practical limits, however, may be hampering your thinking and causing you to make assumptions about what’s really possible.
If you learn to stretch your thinking, you break psychological inertia and discover powerful new approaches.
When problem solving or looking for new ideas, you generally have a good feel for the constraints of any solutions you come up with. When you buy a new car, you know roughly what sort of budget you can afford, even before you calculate the numbers properly. If a sliding scale exists ranging from very expensive cars such as Lamborghinis and Bentleys to more affordable options like Suzukis and Skodas, you probably know roughly where your budget fits on it. This is true of most situations in life when you’re problem solving, even if you aren’t consciously aware of it. That knowledge, of what you believe you can afford or is possible, can result in psychological inertia, whereby you place false constraints on the situation without realising you’re doing so.
Stretching your thinking and pushing constraints on elements such as size and budget is often worthwhile to see if spending just a little bit more can result in a cheaper option over time. For example, choosing a slightly more expensive but also more reliable car that requires less maintenance is probably cost-effective in the long run. You can apply that logic in both directions, so also consider spending less. Doing so may deliver as much as you want or need but you simply hadn’t considered that option. When you work through this TRIZ process, you don’t push your thinking a little, you think in extremes. You imagine what kind of car you’d have with both a zero and an infinite budget and a really enormous and tiny car, as shown in Figure 7-4.
Stretching your thinking in this way allows you to consider all types of solution beyond your initial assumptions and helps you come up with other ways in which to get the things you want. You may want a car that’s suitable for a number of different purposes, such as taking long business trips, transporting large amounts of groceries and getting about town. Stretching your thinking so that you imagine an unlimited budget may suggest employing a chauffeur or buying a fleet of different cars, each perfect for its individual task. A zero budget may suggest not buying a car at all and using public transport. Bringing these ideas back to reality may suggest choosing a car most suitable for one task and finding alternatives for the others; for example, buying a small car for getting about town, hiring a big car for long journeys and getting all your groceries delivered.
The benefit of thinking in extremes is that you don’t have to worry about practicality (at first). Often, when you’re trying to think of solutions to real problems, you start to judge ideas almost immediately, testing them and picking them apart as they’re generated. Doing so slows you down and can be discouraging. The luxury of playing with extreme, impractical ideas allows your brain to work most effectively because you’re not constantly second-guessing yourself and instead your thinking can flow freely. After you’ve generated impractical ideas, you can then work out how to turn them into reality.
You stretch your thinking in this way using the Size–Time–Cost tool, as shown in Figure 7-5. These are the parameters that most commonly constrain your thinking, but you don’t have to limit yourself to these. You may want to consider other parameters, such as number of staff if you’re trying to solve a staffing issue. You can consider tackling the problem with an infinite number of people and no people at all.
Consider trying to reduce energy use in an office building. Here’s an example of using TRIZ creative thinking tools to generate innovative solutions.
Table 7-1 Using Size–Time–Cost to Reduce Office Energy Use
Size |
|
Infinitely large |
Build our own power station. Do something to the building as a whole, for example, improve insulation; change windows to reduce energy loss. Move office location to a more temperate region. |
Infinitely small |
Change office temperature according to the seasons and ask everyone to dress more appropriately as a result. Manage door and window openings more effectively. Don’t heat/cool all parts of office. |
Time |
|
We have forever |
Design new building that requires less energy. Conduct full analysis of energy use to discover the source of most losses. |
We have no time |
Adjust thermostat up or down a couple of degrees (depending on whether it’s cooling or heating). Move equipment and people around to manage heat better; heat or cool different parts of the office differently. Move to energy-efficient bulbs in all light fittings. |
Cost |
|
Infinite budget |
Buy or build a new building. Invest in research to identify equipment that requires less energy or is self-powered. Apply for grants to fund a partial move to renewable energy sources; for example, solar panels. |
No budget |
Find ways to use less energy; for example, make sure equipment is turned off when not needed (rather than placed on standby). Remove unnecessary or excessive equipment that consumes energy; for example, reduce number of fridges or printers; encourage people to take a paperless approach in their work. Make sure lights are turned off when rooms are not in use. |
