The Covid-19 pandemic – now rarely spoken about and largely consigned to the history books – irrevocably changed the way we work. Almost overnight, organisations scrambled to shift to online and remote working. And while many businesses have since returned to the office, a significant proportion of our working lives remains digital. We collaborate with clients, customers and colleagues across the world without boarding a plane. We move from one meeting to the next from the comfort of our office chair. We have opportunities to connect with others and share widespread project updates at the touch of a button.
But while organisations made that switch, something else happened. Our attention spans shrank, distractions loomed, and sustained focus became harder to achieve.
As our reliance on online collaboration tools grew, so too did the cognitive load placed on our working memory – often putting a brake on our ability to think clearly. In this article, we’ll explore how modern collaboration tools have the potential to both help and hinder cognitive load, and what managers can do to design ways of working that support their team’s thinking.
What is Cognitive Load?
Cognitive load refers to how much effort our working memory is using at any given moment. Our working memory is finite – meaning that when it’s overloaded, it becomes harder to process new information or make good decisions. Yet information processing and decision making are the cognitive acts that underpin our teams’ day-to-day performance, and when they begin to break down, the impact on productivity can be significant.
Think of your laptop: when too many apps or browser tabs are open, the processor slows down. For individuals in today’s online world who are constantly navigating tools, switching between conversations, tracking information across multiple channels or recovering from interruptions, unnecessary cognitive load quickly builds up. Over time, it erodes our capacity to think clearly.
It’s important to note that, as managers, we can’t remove all the cognitive load our teams experience. After all, complexity is unavoidable in many roles. What we can control, however, is how we design meetings and collaboration systems to reduce unnecessary load – leaving our teams with more mental capacity for the learning and decision-making that is crucial to achieving goals and outcomes.
How Do Online Collaboration Tools Increase Our Cognitive Load?
Online collaboration tools – such as MS Teams, Notion, Slack and Trello – make modern work faster and more flexible. However, the way these tools are typically used can place a persistent and often invisible load on working memory. Individually, each demand may seem minor. But collectively, they create a constant background pressure on our cognitive resources which leaves less capacity for sustained focus and deep thinking.
Four patterns are particularly common in digital collaboration.
Notifications
Notifications
Pings, banners and pop-ups constantly pull attention away from our team’s focus and we just can’t ignore them. Each interruption forces the brain to pause and take in new information before returning to the task at hand, adding yet more load to our working memory.
Channel Switching
Work regularly unfolds across email, chat, shared documents and meetings (amongst other places). Moving repeatedly between platforms and threads requires us to hold multiple streams of information in mind, increasing the risk of errors and details becoming missed.
Attention Residue
When we shift rapidly from one task or conversation to another, a portion of our attention remains attached to what we were just doing. Over time, this residue accumulates, reducing our brain’s ability to fully engage with the task in front of us.
Parallel Conversations
Meetings accompanied by live chat, side conversations running alongside main threads and multiple conversations unfolding at once place heavy demands on the working memory. Listening, reading, typing and deciding simultaneously leaves little capacity for reflection or sense-making.
While online collaboration tools have transformed the way we work for the better, the hidden demands they place on working memory can come at a cost to efficiency. As managers, we have a role to play in designing collaboration that protects our teams from unnecessary cognitive load.
Signs Your Team’s Cognitive Load is Too High
Excessive cognitive load often shows up through a pattern of subtle but persistent issues, rather than one obvious problem. Common signs include:
- Decision paralysis – Even relatively simple choices take longer than they should or are repeatedly deferred as teams struggle to prioritise or commit.
- Feelings of overwhelm – Individuals may feel mentally drained or overstretched, even when working on tasks that are not inherently complex.
- Less effective learning – New information is less likely to transfer into long-term memory, making training or the implementation of new systems or procedures feel forgettable and difficult to apply in practice.
- Decreased motivation – As cognitive load rises, effort can start to feel disproportionately high compared to progress made, reducing confidence and engagement.
- Increased errors – Too much mental energy is spent managing the work and the communications around it, rather than doing the work itself.
How Can Online Collaboration Tools Help With Reducing Cognitive Load?
Despite these pitfalls, online collaboration tools can play a powerful role in reducing cognitive load. When used wisely, these tools help teams offload mental effort, making their thinking more visible and manageable.
One of their most valuable functions is as an external memory. Task boards and knowledge bases allow information to live outside our heads, reducing the need to remember details. This frees up working memory for more meaningful thinking.
They can also support clarity and prioritisation. Well-structured project boards, agendas and shared plans make it easier to see what’s next and who owns what, reducing the cognitive strain of constantly reinterpreting priorities.
Digital tools can also reduce load through automation. Templates, recurring workflows and automated reminders remove the need to repeatedly decide how to do routine work, allowing teams to focus their mental energy on the work itself rather than the mechanics around it.
Finally, collaboration platforms can support cognitive load by enabling more asynchronous ways of working. When used well, this allows individuals to engage with information at a time and pace that suits them, rather than being forced into constant real-time responses that divide attention.
Tips For Reducing Cognitive Load When Collaborating Online
Reducing cognitive load in digital collaboration requires thoughtful design choices about how existing tools are used. Below are some practical ways to shape your team’s ways of working to minimise unnecessary and distracting information.
2. Set clear expectations around responsiveness
When everything feels urgent, our working memory is constantly on alert. So, agree what urgent really means, and which channels should be used for what communications. Clear norms reduce the mental load of deciding when and how to respond.
3. Reduce the number of places work lives
Where possible, streamline channels so teams are not forced to search across multiple platforms for the same information. Fewer places to look means fewer decisions to make and less mental energy spent reconstructing context.
4. Design meetings to support thinking
Use agendas, shared documents and pre-reading to make the purpose and outcomes of meetings explicit. Avoid running chat and meetings in parallel unless it adds value, and consider transcribing meetings as standard so that less cognitive energy is spent trying to retain and remember information.
5. Make decisions and outcomes visible
Capture and share key information in a consistent place. This reduces the need for people to remember, re-ask or reinterpret what was agreed – freeing up working memory for higher-value work.
6. Standardise where you can
Templates, naming conventions and consistent ways of structuring work remove the need to repeatedly figure out how to do things. This reduces decision fatigue and creates more mental capacity for the work itself.
7. Lead by example
Managers set the tone for what “normal” looks like. Blocking focus time and avoiding unnecessary notifications sends a far stronger message than any written guideline ever could.
Final Thoughts
The key to reducing unnecessary cognitive load is ensuring that mental effort is spent on the work that truly matters.
