The author of multiple articles in Scientific American, Science, APA Monitor, and other publications, she is a co-founder and the executive director and editor-in-chief of The Open Notebook. In 2018 Carpenter was elected to a two-year term as president of the National Association of Science Writers.

Early life and education Carpenter grew up in La Crescent, Minnesota. She is married, with two daughters, and lives in Madison, Wisconsin. She completed her undergraduate education at the University of Wisconsin–Madison, earning a B.A. in psychology in 1995. She earned an M.S. in 1997, and Ph.D. in 2000, both in social psychology at Yale University. Her dissertation, Implicit gender attitudes, was directed by Mahzarin R. Banaji.

Career

Early career In 1998 Carpenter was a Science and Engineering Mass Media Fellow of the American Association for the Advancement of Science, at the Richmond Times-Dispatch in Richmond, Virginia. The following year she was a science writer intern at Science News in Washington, D.C. After completing her Ph.D., Carpenter was hired as a senior science writer for the APA Monitor on Psychology in Washington, D.C., from 2000 to 2002.

Science journalist, editor Carpenter's career as a freelance science journalist began in 2002. She has written for media outlets including The New York Times, Science Magazine, Scientific American, Science News, and others. From 2012 to 2014, she was a senior editor and then a features editor at Discover Magazine in Waukesha, Wisconsin. Carpenter has also worked as a freelance editor for several publications, including bioGraphic, and Science News for Students. In 2025, she joined the National Academies of Sciences, Engineering, and Medicine Standing Committee on Advancing Science Communication.

The Open Notebook

In 2010 Carpenter co-founded The Open Notebook (TON), a science journalism non-profit organization, magazine and publisher, with Jeanne Erdmann, a health science journalist. Carpenter is executive director and editor-in-chief, and serves on the board of directors; Erdmann is an emeritus board member. Gary Price of Library Journal said The Open Notebook "provides unique tools and resources to help science journalists at all experience levels hone their craft".

National Association of Science Writers Carpenter was vice president of the National Association of Science Writers (NASW), 2016–2018, and was elected to a two-year term as president in 2018. NASW is "...a community of journalists, authors, editors, producers, public information officers, students and people who write and produce material intended to inform the public about science, health, engineering, and technology".

Publications

Books In 2007, Carpenter and Karen Huffman wrote the textbook, Visualizing Psychology. A second edition was published 2010, and Wiley published the third edition in 2012. In 2020, TON published The Craft of Science Writing: Selections from The Open Notebook, edited by Carpenter. Jonathan Wai wrote in Psychology Today, "...a new book edited by distinguished science writer Siri Carpenter seeks to illuminate The Craft of Science Writing by collecting numerous perspectives from science writers themselves about how to improve their own craft of science writing." In 2024, a second, expanded edition of The Craft of Science Writing: Selections from The Open Notebook was published by the University of Chicago Press. In 2026, the University of Chicago Press published The Best Science Stories and How They Work, a collection of 11 annotated science articles and accompanying author interviews; the volume was edited by Carpenter.

Worked examples

Example 1 — a first encounter with Siri Carpenter

Start with the simplest possible case. Write down what Siri Carpenter claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Siri Carpenter before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Siri Carpenter ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Siri Carpenter

In research: Siri Carpenter appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Siri Carpenter in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Siri Carpenter is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1971 births, 21st-century American journalists, 21st-century American non-fiction writers, so understanding it makes those chapters shorter.
In everyday life: Look for Siri Carpenter outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
