Because reading time is set aside during the meeting, everyone has the same opportunity to engage with the material. This levels the intellectual playing field. We are not allowed to drift away, as might happen during a presentation; if people finish reading early, they generally spend the rest of the allotted time taking notes. It is understood that during the session, distractions should be kept to a minimum.

Sometimes, I have had to ensure that people don’t exceed the six-page limit. Most memos end up being about 1,900 words (five to six pages), including figures and tables. But the page limit isn’t really the constraint; the 20 minutes are. If we can’t read the document in the allotted time, it is too long.

When I suggested that we start using this technique, I did not enforce a specific template. However, a common format has stuck: the memo starts by posing the problem or question it discusses and ends with questions that the author hopes will be answered after the discussion.

Opening up to the lab

For the first year, the memos were what I expected: discussions of protocols, pilot data, software and case studies. Then, a postdoc used her slot for a memo titled ‘Help! What’s my research profile?’ She was eight years into her research career but could not articulate the specific area of scientific investigation she was known for in the field, and she asked the room for help with working it out. She was sharpening her academic profile for job and grant applications at the time, and this brainstorming session helped her to consider all of the work that she had done and excelled in, and gave her enough distance from her research to see the common thread running through it. Two months later, a second postdoc cited that meeting in her own memo about refining the direction of her research. And five months later, a PhD student at the halfway point of his doctorate cited both and did the same.

None of them would have made a slide deck about that topic. A talk is generally a description of finished work. A memo, by contrast, is a document that can discuss uncertainty.

A record of our work

We move from topic to topic in our meetings, keeping all of the memos on an internal database. In doing so, we have created an objective record of how our lab’s thinking has changed over time, and how the team has matured, in a way that slide decks could never achieve. We invite newcomers to the lab to browse the archive to help them to understand the culture of the team that they are joining.
