How You Can Stick With A Tough Problem – Key Lessons From Cognitive Science

David Badre shares some ideas about working on complex and challenging projects

David Badre is a professor of cognitive, linguistic and psychological sciences at Brown University in Providence, Rhode Island, and author of On Task: How Our Brain Gets Things Done.

I have edited some of the authors’ critical points about practising problem-solving habits and added some keyword labels in bold.

In general, we can get better at structuring hard problems with experience. This is one reason that practice makes us more efficient and successful at hard tasks and that experts outperform novices. Finding work habits that encourage this process helps us to stay focused.

  • Stay with it. Finding the right structure often takes time. [Persist, Stamina, Effort]
  • Be open to reconceptualising problem structure. [Disposition, Curiosity, Perspective]
  • Take breaks. It’s not helpful to insist on trying to get everything done at once if it just isn’t working. [Pace, Time, Incubate]
  • Interact with others. Just like taking a break, interacting with others can help us conceptualise a problem in new ways. [Collaborate, Share, Connect]

I find the idea of being open to reconceptualise problem structures one that resonates with my current facilitation.

I am paying attention to moments when I shift perspective. This is often during group design and development sessions.

For example, during a recent curriculum design workshop, I asked a group of teachers:

If some of your students were here with us, what might they share about the ideas we have developed so far?

This is a deliberate facilitation move to change the perspective.

The problem structure [learning + curriculum design] was shifted [from curriculum] and seen from a different vantage point [student].

This propelled us in a different direction and led to some new ideas.

Avoiding Masterchef style feedback

Her eyes widened and her mouth fell agape. I suspect the ticking clock suddenly stood still and the taste buds, that had become her all-powerful ally, dried up as fast as an unwatched pan of pasta. Her idea had been derailed.

Wherever I look I see processes of critique and feedback. It is unquestionably an integral process for learners. However, it is also a process that binds and carries the progress of many other professions and creative endeavours, as well as almost everything else in between.

That is why when watching the TV show Masterchef, the amateur cooking competition, the impact of feedback was all too present and obvious.

Masterchef style feedback refers to providing feedback at a point when it is creatively inappropriate as well as emotionally challenging to hear.

Now if you have never seen Masterchef let me share the scenario. The contestant I describe had begun a challenge in which they were in a small group of other contestants but cooking independently. They were given a time limit, like 30 minutes, to cook a particular style of dish or create something unique.

I recognise that the pace of the creative process (generating original ideas for a dish) on show here is very high along with the intensity of the environment, time, expectation and competition. This can be a block to creativity.

In this intensity, the contestants are immediately generating ideas as they hear the challenge ahead of them, even before the basket wielding supermarket sweep for ingredients begins. They are all drawing upon a history of cooking, a long line of experience using the ingredients they have and a range of ideas and principles of cooking that have been tried and tested before.

The action usually commences with everyone rushing off to a pantry filled with a plethora of fresh ingredients and cupboard essentials. The ideas for their dish begin to swirl as they are confronted by the swathe of stock laden shelves in the pantry. There are those that pluck what they need, the decision made and those that are still developing something, waiting for inspiration to strike, lost momentarily in the various types of vinegar on offer.

With baskets crammed the cooks rush to their workbenches and stovetops to begin cooking. Stakes are high (fill in your own pun) as they compete with each other, the clock, their own nerves and the judgement of professional chefs and food critics. Suffice it to say that emotionally the environment is highly charged for those involved.

And then comes the first moment of feedback.

Who knows really how much time has passed due to the editing process for television. However typically a trio of judges saunters across to a contestant to try and learn what dish is being made and observe the progress towards that goal. Comments both positive and negative are typically shared with the contestant at this point. This is a moment when really contestants are implementing their idea for the dish, they have committed to it and are pushing on. Feedback which is anything but affirmation is derailing.

So every now and then you see idea derailment in the eyes of the contestant. The widened eyes of an inner struggle to assimilate the expert advice with their emotional and technical commitment to an idea. “How can I possibly change my dish now?!” The contestant has invested in their idea and fast-tracked to implementing it. They are no longer making major decisions about what to do but are now amongst the intricacies of making it happen. Their mindset is no longer in a divergent state but is now one of convergence towards a more and more fixed goal.

It is this style of feedback which I think we have to seek to avoid. After all the cooking on Masterchef, however much a show for TV is still a microcosm of a creative process. This is similar in so many ways to when we ask the learners in our classes to create something, think high stakes, time, judgement.

To avoid Masterchef feedback or idea derailment we simply have to provide more feedback earlier on in the creative process.

In the case of Masterchef the time in the pantry, as the contestants jostle for ideas, inspiration and ingredients, would have been a good time to speak with people to offer ideas and feedback. Sometimes on a show, you see those stranded in the pantry getting a pep talk from a judge as they share and develop ideas together. That early feedback and dialogue are much more developmental and appropriate than derailing ideas already on their way.

In the classroom, we might build in earlier check-ins with learners as they begin the process of generating ideas for their writing, painting, modelling etc. The longer you leave that early check in the more committed to their ideas students will become and there is a higher chance of idea derailment if you offer critique. Plan for feedback to occur early and frequently to catch our young thinkers whilst their mindset is still divergent and open to ideas.

How to Strike a Balance when Generating Ideas

When you use an activity to generate ideas it typically comes with a standard pace setting. The way I see it, the pace dial is usually set between Incubate/Slow OR Force/Fast. This is also the intensity with which we are working or generating ideas.

Force

One idea generation activity is 100 Ideas in 10 Minutes. It is really effective at generating lots of potential ideas for a problem in a short space of time. From the name you can tell the pace is high. Another activity I have written about recently is the Crazy 8s, in which you draw 1 idea every 40 seconds for 5 minutes. This sets a similarly intense creative pace for those involved.

As much as the higher pace, higher intensity tasks tangibly increase the creative energy in the room, they also force the hand of that creative thinking. There are limits and constraints and higher pace. As a result, you create pressure, for some participants (and students) they love that edge. For others, it becomes harder and actually works counter to the general mindset we need for generating ideas: divergence. Too much pressure and pace can be a block to creativity. So we have to handle this carefully and create opportunities for a balance in speed settings if we can.

Incubate

When we incubate ideas we are taking our time to mull and ponder them over. We cogitate on them and allow ideas to be twisted and turned at a more leisurely pace. No time limits, no facilitator telling you, “Next one, move on!” When we incubate ideas we actively create conditions for our brain to slowly generate new connections and new ideas.

When you look through these brainstorming routines from Melanie Pinola, for example, you will see that the majority of them require the pace-setting to be quite low. Take a walk; in the shower; take a nap. The slower pace allows our brain to continue to work the connections. I have written before about Purposeful Napping, the deliberate use of sleep inertia to unlock our creativity. Take Edison’s lead on this one.

Suffice it to say that when we are engaged and motivated around a meaningful problem, we can guarantee our subconscious brain will continue to work hard. It has evolved to make connections from stimuli and will continue to work away at developing ideas or trying to break open a problem. We just need to give it deliberate time to work and create simple methods for capturing those ideas and connections if and when they are generated. Notebook in the shower type stuff.

Strike a Balance

A way to combine the power of these different pace settings is to seek out a balance, not only in the pace but the style of activity too. Here are a few ideas for you to takeaway:

  1. Combine activities so that they complement each other, go fast and slow.
  2. Provide time after an intense activity to go for a walk or work on something else, deliberately choosing to switch off.
  3. Arrange for these Force activities to happen at the end of the day so that the pace shifts overnight.
  4. You may even ask your students or participants to not think about the task anymore. Invariably new ideas are created and developed.
  5. Plan for downtime. Don’t overfill time with your students or colleagues that is for idea generation. Plan for deliberate Incubate style sessions.
  6. Talk explicitly with your team about the pace settings of the different tasks. Build up a picture of the pace settings for each tool in your creative toolset, share that understanding.
  7. Differentiate. This comes straight out of Teaching 101. Each team member or student will respond to the pace and intensity of an idea generation task differently. Talk about how they feel after different sessions and plan for the most appropriate combination of tasks for teams in the future.
  8. Increase your awareness of the pace-setting for tasks. When you debrief about different activities consider the intensity and pace. By staying aware of how others respond to them you are better equipped to choose suitable tasks. Understand the task design and the expected pace and observe how this impacts on those involved.

I find the Force Vs Incubate spectrum to be a really effective way to design idea generation tasks for any group. Just ask any group about when they generate their best ideas and it typically is not during a set-piece task. Strike the pace balance and we are much more likely to be utilising the best creative activities from our toolset.

As ever, let me know what resonates by sharing a comment below.

3 Activities to Help Your Team: Generate, Develop and Judge Ideas

There are hundreds of different activities you can use for generating and developing ideas. I thought I would share a trio that works well together. They each require a specific type of thinking or mindset to be successful. The three activities are good representative examples of Divergent, Emergent and Convergent thinking.[1]

I have picked these three because they flow well together, and although they work well on their own, they complement each other well.

1. Crazy 8s

Time: 5mins / Skills: Idea generation / Mindset: Divergent or Open thinking / Resources: 8 Post-it notes per person, felt tip pens / Group: Ideal for small-medium sized groups, you will need a timekeeper. Independent work.

Generate eight different ideas in 5 minutes.[2]

Sounds easy enough, but this is a challenging little task. For each round, participants have 40 seconds to draw an idea on a post-it note. When the first round is done, the timer is immediately reset, and the second round begins for eight rounds in total, 5 minutes.

The most challenging part for most participants is that you can only draw the idea – stick to the no words rule. It means they have to generate an idea and then communicate that. It is worth spending some time being clear about the mindset of divergence and openness. All too often, we are our own worst filters, and people find this hard to shake.

2. Idea Pairs

Time: 15–20mins / Skills: Idea development / Mindset: Emergent or Exploratory thinking / Resources: Post-it notes, felt tip pens / Group: Ideal for small-medium sized groups that are comfortable working in pairs.

Combine ideas and discuss in a pair how they could work together.

I like the simplicity of this next step, and it flows seamlessly from the intensity of Crazy 8s[3]. Once you have finished the first step task (Crazy 8s), each participant will have many ideas; hopefully, they will have eight post-it notes in front of them, so long as they didn’t bail halfway through.

Ask the group to get themselves into pairs to discuss some idea combinations. Each person in the team picks one of their ideas at random and combines it with the arbitrary choice of their partner. Placing the two post-it notes side by side. Through discussion, the combination is explored, and new ideas are noted; this should increase the pool of ideas around the table.

I find this simple step is a great way to collide ideas that might have remained in isolation. It also helps participants talk through their thoughts, developing them further. An Exploratory or Emergent mindset is needed here, which emphasises the need for developing, pushing and prodding ideas in new directions.

3. Impact Vs Effort Matrix

Time: 20–30mins / Skills: Idea filtering / Mindset: Convergent or Closed thinking / Resources: Post-it notes, felt tip pens, whiteboard or large flip chart paper (tabletop also works fine) / Group: Small to medium group size for discussion.

Judge each idea created against a High/Low measure for Effort to implement and the impact it could have.

I always enjoy using this little matrix[4] to judge a smaller handful of ideas. You might have anything from 30–50 ideas from the group, depending on the group size. You might ask the whole team to pick 2–4 of their ideas to bring into this round; perhaps the pairs from the previous activity will discuss what to keep and what to cut. Once you have done that first filter, you can decide what High/Low for Effort and Impact is.

Draw up a four-quadrant matrix on a whiteboard or use some masking tape to do the same on those furry display boards! Label the axes accordingly:

  • HIGH EFFORT
  • LOW EFFORT
  • HIGH IMPACT
  • LOW IMPACT

Now, all you have to do as a team is discuss each idea and place it, measuring/judging the effort needed and its potential impact. This process is always a great way to converge into a small pocket of ideas that fit your requirements. You should pin up the post notes and shuffle them around as you chat about their potential.

From doing this many times, I would say that it is useful, as more ideas are added to the matrix, to compare ideas directly: “Will this be harder to implement than this one?” etc. Another tip would be to consider the trajectory of the ideas over time. Efforts to implement and impact may reduce or increase – mark up the future course and discuss what this means.

This is an effective task to help the group understand what is practical under the constraints you have as a team. It pushes you to make comparisons between ideas and prioritise and rank them in interesting ways. When you are in this state, you narrow your options and are thinking in a more Convergent manner.


Well, I hope those three little tasks prove helpful to you and your teams/students in the future. They flow well together and require barely any unique resources. They also fit within an hour if someone is cracking the whip and facilitating well – typical of the ideation phase. The critical thing for each step is to explicitly flag the mindset or thinking state needed to be successful. They are great examples of the three different thinking states: Divergent, Emergent and Convergent.

Give them a try, and let me know how you get on. Remember that these three tools are three of many, and you should do everything you can to expand the choices you have in your toolset. When you have more options, you can make better combinations of activities such as this trifecta.


  1. It is through these different thinking states that we typically experience a creative process. They often fall in the order written above but just as frequently break that rhythm. You can read a little more about the ebb and flow between divergent and convergent thinking in my previous blog post.  ↩
  2. I first came across the Crazy 8s ideation strategy from Google Ventures and a Jake Knapp blog post which is worth a read – lots of other ideas there too.  ↩
  3. I’d recommend building in some time to debrief after Crazy 8s. It is quite an intense task requiring focus and individual effort. Spend some time asking how people felt and how they found the task – giving the participants some time to chat will help the overall flow.  ↩
  4. The Matrix is everywhere. It is all around us. Even now, in this very room. You can see it when you look out your window or when you turn on your television. You can feel it when you go to work… when you go to church… when you pay your taxes. It is the world that has been pulled over your eyes to blind you from the truth.  ↩

The ebb and flow between divergent and convergent thinking

I thought I would take the opportunity to return to an article I wrote a few days ago. My blog post outlined a few of the key issues for developing creative teams. The article that inspired it from HBR[1] gave a broad definition of innovation and creativity which resonated strongly with my own experience in schools.

According to the author, Roger Schwarz[2], researchers commonly make a distinction between the definition of creativity and innovation.

Innovation involves two stages—the generation of new ideas and the implementation of the ideas. Creativity is considered to be the first stage of innovation.

I would call implementing ideas Prototyping and this typically comes after a range of ideas have been sorted, filtered and judged in different ways during Ideation. I always see a change in the energy levels during Ideation as people begin to flex their creative muscles more intensely.

Later in the article Schwarz outlines a conflict in factors that affect innovation, explaining that a different type of thinking is needed.

Creativity and the second stage of innovation require different individual skills and team structures and processes. The idea generation stage is often referred to as divergent thinking or exploration. The implementation stage is often referred to as convergent thinking or exploitation. Unless you plan to have your team hand off its creative ideas, you will need to create a team that can operate in both modes, switching among them as appropriate.

This whole area is invariably complex and more research is needed. However even from my own experience the requirements on an individual are much more intricate. I agree that we need to be in a divergent thinking state when we generate ideas, but this changes when we have to decide on which ideas are worth investing further in. It changes to a convergent thinking state. In order to identify our choices we have to narrow our field, we have to purge the ideas that don’t make the cut. For us to successfully judge a set of ideas we have to be able to converge and begin to make choices. Thinking big (divergently) and generating ideas at this stage would certainly be counterintuitive.

The ebb and flow between divergent and convergent thinking at the ideation stage is quite important and much more frequent than is suggested in the article. Idea generation is but one part of Ideation. Of course we may identify Emergent thinking as well at this stage which is exploratory and helps when we want to develop our ideas further. I see Ideation being made up of the sequence below:

  1. Generate Ideas (Divergent or Open Thinking)
  2. Explore and develop ideas (Emergent or Exploratory Thinking)
  3. Judge and shortlist (Convergent or Closed Thinking)

It is extremely useful to have a language for the thinking state or mindset needed. I would highly recommend sharing the definitions and helping others understand them. Talking explicitly about the thinking that is needed to be most successful helps signpost people to such expectations, and has helped countless teams of adults and students I have worked with. Don’t let this be a wishy washy stage, identify a process, like the sequence above and stick to it. Trust in the process.[3]

Once ideas have been explored and narrowed down then a team would move on to implementation. Taking a concept into a working or minimal viable prototype phase. Again the type of thinking here is not simply convergent as Schwarz outlines, in my opinion it is equally fluid and perhaps also made up of the combination of divergent, emergent and convergent thinking states.
