Reading Habits of Famous Scientists

Reading as part of the job

For a working scientist, reading is not a leisure activity added to the day; it is built into the work. New findings appear in a continuous stream of papers, and a researcher must know what has already been shown before designing an experiment or interpreting a result. Add to that the reading of data, methods, grant documents and the work of students and colleagues, and a large share of a scientist’s week is spent with text.

This article describes the habits scientists commonly mention, in general terms. It names no individuals and no publications, and it reports no study of its own. The picture comes from how research is usually taught and discussed, and individual practice varies a lot by field and by person.

How scientists read papers

A research paper is not written to be read like a story from first line to last, and experienced readers rarely approach it that way. A common pattern, which varies with the reader and the field, runs roughly like this.

1. Look at the title and abstract. This answers the first question: is the paper relevant at all? Most papers a researcher meets end here.
2. Look at figures and tables. Results are often easiest to judge from the data presentation, and many readers form a first impression from these before reading the text.
3. Read the introduction and conclusions. These give the question the authors asked and what they claim to have found.
4. Read the methods and results closely, only if needed. If the paper matters to the reader’s own work, the details matter: how the data were gathered, how large the sample was, what was compared with what.
5. Check the references. Following citations backward leads to earlier work and shows how the paper fits into a longer conversation.

This is a form of previewing a text and then skimming and scanning, followed by close reading of the parts that count. It saves time, and it also reflects the reader’s purpose: a scientist reading to stay informed reads differently from one trying to replicate a method.

Reading critically

Scientific training emphasizes skepticism. Readers ask whether the evidence supports the conclusion, whether other explanations were considered, whether the sample was suited to the claim and whether the result has been repeated. A single study is rarely treated as settled.

This habit is valuable for any reader of news about science. A headline may overstate a modest finding, and a single result is different from an established body of knowledge. Learning to tell a measured claim from a sweeping one is among the most transferable skills of scientific reading, and it is closely related to the practice of reading statistics carefully.

Reading across fields

Many scientists describe reading beyond their narrow specialty. Some of the most interesting questions sit between disciplines, and methods developed in one area, such as statistics or imaging, often turn out to be useful in another. A biologist may read about mathematics, a chemist about computing and a physicist about the history of ideas.

The reasons given are generally about curiosity. People attracted to science tend to want to know how things work, and that wants more than a single field can answer. Wide reading also helps with communication, since it shows how other specialists explain themselves.

It is reasonable to add a note of caution. We cannot say that wide reading produces better science; it is just as plausible that curious people read widely and also do good work. What can be said is that breadth gives a researcher more to connect.

Popular science and history of science

Many researchers read general-audience science writing, both in their own areas and in unfamiliar ones. Good popular science gives a reader the shape of a subject without requiring technical training, and it can be a way for a specialist to learn about a neighboring field. Some scientists also read the history of their disciplines, which shows how ideas were tested and how often confident views were later revised.

That last point teaches humility. Reading how earlier generations were sure of things that turned out to be wrong is a useful counterweight to overconfidence about current views.

Keeping up without drowning

The volume of scientific publishing is far too large for any person to follow completely, so scientists develop ways to cope. Common approaches include:

• Setting up alerts or regular scans for a narrow set of topics.
• Reading summaries and reviews that gather many studies in one place.
• Discussing papers in a lab or reading group, which splits the load and exposes weak points.
• Keeping notes or a reference library so that a paper read once can be found again.
• Accepting that most things will go unread.

The last point is worth stressing. Good readers are selective, and they do not feel guilty about it.

What a general reader can borrow

You do not need a laboratory to use these habits.

• When reading about a scientific claim, look for the source and ask what kind of evidence it is.
• Read the abstract or summary first, then decide whether the rest is worth your time.
• Read widely out of curiosity, including fields you know nothing about.
• Write down questions as you go, and follow one or two of them.
• Treat a single study as a clue, not a verdict.

A note on health: reading about medical research can be informative, but it is not a substitute for advice from a qualified professional about your own situation.

The enduring lesson from the way scientists read is a combination of focus and curiosity. They are selective about what to read closely, skeptical about what they read, and open to unexpected sources of ideas. Those habits are available to anyone, whatever their training.
