5 Ways to Overcome Information Overload in the Workplace

Emails, messages, meetings, and decisions can pile up quickly. Columbia Business School professor Sheena Iyengar, an expert on choice, estimates that the average knowledge worker must process, consciously or subconsciously, the equivalent of 174 newspapers of information every day.

That level of information overload can derail your focus, lead to poor decisions, and increase the risk of burnout. So how do you protect your time, energy, and attention in a world full of constant input? One solution is to leverage tools like Slack that help streamline communication and reduce unnecessary distractions.

 

What is information overload?

Information overload refers to the state of being overwhelmed by the sheer volume of data, messages, and decisions we encounter daily. Constant digital communication, task switching, and multitasking can stretch our attention and reduce information processing capacity.

The consequences of information overload can include decision fatigue, poor concentration, and increased stress. In short, too much information can make it hard to get anything done.

 

The emotional toll of information overload

The effects of information overload aren’t just cognitive, they’re emotional, too. Stress and fatigue from a constant flow of data can impact you mentally and physically, causing burnout, irritability, and loss of motivation.

To protect your well-being, it’s important to build emotional distance from each piece of information. Setting boundaries, disconnecting regularly, and labeling tasks (“this isn’t urgent”) can help restore a sense of control.

Five ways to manage information overload

Iyengar points to five actionable strategies that can help workers deal with information more intentionally.

1. Be choosy about choosing

According to Iyengar, knowledge workers who manage their time well regularly ask themselves, “Is this worth my time, or is this something I should be delegating?”

With so many emails to respond to, meetings to attend, projects to participate in and tasks to complete, knowledge workers have to become the gatekeepers of their own time management and attention by using the right collaboration tools. Slack allows teams to centralize their communication, reducing the need for constant email check-ins or interruptive meetings. Knowledge workers who aren’t choosy are less likely to be proactive where their attention is needed most. “Instead of actually addressing their priorities, they end up putting out fires. They’re being more reactive to what’s coming at them on a minute-by-minute, day-to-day basis,” Iyengar says.

When you’re selective, you can get rid of what’s less important and delegate or outsource tasks that don’t align with your strengths and interests. By taking those items off your to-do list, you can devote more time and brainpower to activities that add value and better deal with information in a focused way.

2. Identify three to five priorities

The human brain can remember around seven things—give or take—at any one time, according to Iyengar. And if you have to keep looking at your to-do list, that’s a problem. She recommends narrowing down your priorities to the top three to five things that matter most to you, since even seven can be a stretch.

Once you’ve got your list, Iyengar recommends going one step further to focus on exactly what you need to do to accomplish each one. To avoid information overload, she suggests asking yourself three questions:

• What’s the problem I’m trying to solve?
• How do I break down this problem?
• What information do I need to figure out the best solution?

By getting very specific about what you’re looking for and why, you can proactively approach information processing, rather than reacting to every piece of information available.

3.

Not all tasks and decisions are equal. For instance, deciding what to have for breakfast merits less time and research than, say, deciding whether to accept a new job offer.

Knowing where a decision or choice falls on the hierarchy of importance can help you assess how much time to invest in it. For example, Slack’s customizable notifications allow you to control which conversations or task lists need your immediate attention, reducing the cognitive load of constant interruptions. Sometimes you may need to “choose nothing less than the very best,” Iyengar says, and other times the ideal action is to “simply stop because it’s good enough for this decision.”

By identifying which choices are worth extensive time and research and which aren’t, you free yourself up to make effective decisions when it counts and reduce the effects of information fatigue.

4. Put a time limit on information gathering

Without setting parameters on time, knowledge workers can get sucked into information and choice overload. As Iyengar notes, the abundance of information can be addictive and seductive.

To avoid unproductive rabbit holes, Iyengar recommends putting a time limit on information gathering. “Gone are the days where you just said, ‘Hey, let me just explore and see where I go,’ ” she says, “because two hours will pass and you’re going to realize you’ve gotten nothing done.” Slack’s “Do Not Disturb” feature lets you set time blocks to focus, reducing interruptions and helping you be more intentional with your time.

How you use your allotted time can vary; what’s key is being strategic about it. “For some of us, you might decide that it’s more important that you spend one or two hours exploring lots of different things—that’s your time to really add creatively to your knowledge base,” she says. “For others, it may be a time to create focus and only search on that topic during the allotted time.”

5. Schedule related tasks together

Once you’ve identified your top priorities and the information you need, Iyengar says, the key to improving productivity is to work on related tasks in regular intervals. By scheduling tasks next to each other in 30-minute blocks, you’re less likely to get stuck in a mental rut or bogged down by information overload, she says. By creating Slack channels and organizing discussions, Slack helps ensure that employees focus on what matters most. Slack AI further reduces noise by offering features like channel summaries, thread recaps, and AI-powered search, so you can quickly catch up on what matters without sifting through endless messages.

Moving between unrelated tasks, on the other hand, creates a cognitive burden that can inhibit productivity. Iyengar understands that sometimes switching between different tasks is unavoidable, but acknowledging the mental cost of the transition can help. “When you’re going to start a new task—let’s say you need to learn a new app or you need to upload some new file in a new way—build in the fact that there’s going to be a startup cost so that you’re not frustrated,” she says. “Because once people get frustrated, they actually lose a lot of energy through their frustration.”

Understanding the consequences of information overload

When information overload goes unchecked, it doesn’t just slow you down. It can take a toll on your mental well-being, make teamwork harder, and hurt your overall performance over time. Some of the most common consequences of information overwhelm include burnout, decision fatigue, and feeling less satisfied with your work. The good news is that once you recognize these effects, it becomes easier to take steps that lead to better focus, stronger collaboration, and healthier work habits.

The power of choice

While information overload can make daily decisions challenging, Iyengar reframes our ability to choose as a powerful tool. By helping us determine what’s useful and relevant, choice frees us up to invent and create. “We can use choice to construct those most meaningful combinations of our lives,” she says. “I think that’s when you get the real power of choice.”

The true value of choice is not standing in front of a vending machine and making a selection, she says. Rather, it’s saying, “Look, I’ve got this problem. How can I now imagine a solution and implement it in a way that actually makes a difference? By using tools like Slack to manage information flow and prioritize effectively, you can combat information overload, stay focused, and improve productivity in the workplace.
