TBSP (Too Busy, Summary Please): Being able to find something and being able to use it are two different skills. Across five experiments, people who connected with others before learning new material remembered about 40% less of it, while getting much better at tracking who knew whom. Knowing where information lives is handy, but judgment runs on what is already in your head. This week: how to retain information at work by sorting what you can safely look up from what you need to learn, plus three habits that make the important stuff stick.
What if the tools that make information easier to find are making it harder to keep? Researchers Esther Kang and Arun Lakshmanan ran five experiments with more than 1,000 people. Participants who formed social connections before learning new material remembered about 40% less of it. If you have ever wondered how to retain information at work when every answer is one search or chat message away, that number deserves a second look.
The same participants got better at something else. They were roughly 65% better at remembering who was connected to whom. Their brains made a trade. They stored a map of who had the content and let the content itself go.
Your Brain Made a Trade
Kang is clear that this isn’t laziness. People with stronger working memory showed the pattern even more, which points to efficiency. Why memorize something when you know exactly who to ask?
The catch shows up when you need to use what you know. Knowing who has the answer is like knowing which shelf holds the cookbook. That helps, right up until you have to improvise dinner with half the ingredients missing.
Judgment works the same way. Making a call mid-meeting or spotting the flaw in a proposal draws on what you have already absorbed. You can’t look up a hunch.
How to Retain Information at Work Without Memorizing Everything
Trying to memorize everything is its own trap. The better move is sorting. Writing in Harvard Business Review, Kang advises separating what people can look up from what they need to internalize to make sound decisions and solve new problems.
Policy details, formulas, and the name of the vendor you used two years ago can live in a search bar. How your customers think, why your team’s process works the way it does, and the core ideas of your field need to live in you.
This fits a principle at the heart of David Allen’s Getting Things Done method. GTD moves reminders and commitments out of your head and into a trusted system so your mind is free to think. The new research adds a useful boundary. Offload the reminders. Keep the understanding. If you haven’t built that system yet, start with the five steps of the GTD method.
Three Ways to Make It Stick
Kang recommends building learning into the work itself by having people explain, apply, debate, and teach what they find. Each of those works for one person as well as a whole team.
- Explain it in your own words. After reading something important, write two or three sentences about it without looking back. If you can’t, you found it but haven’t learned it yet.
- Use it soon. Apply the idea to a real decision, email, or project while it’s fresh. Using information is what moves it from “I saw that” to “I know that.”
- Teach it or argue about it. Bring the idea to your next one-on-one or team meeting and invite pushback. Saying it out loud exposes the gaps faster than rereading ever will.
If you manage a team, these habits scale. Rather than forwarding an article with “FYI,” ask someone to bring the one idea worth using to the next team meeting and explain how it applies to your work.
Know Who Knows, and Know a Few Things Yourself
Knowing who to ask is a real skill, and a well-connected team is worth a lot. Learning how to retain information at work gives you enough in your own head to recognize a good answer when someone hands it to you. It also helps you ask a sharper question in the first place.
What’s one thing you keep looking up that you’d be better off knowing?
