# Mind Amplifier: Can Our Digital Tools Make Us Smarter? *By Howard Rheingold. TED Books (TED Conferences), September 2012. A short e-book, not a print book. The author also posts a PDF on his own site.* > I did not read the whole book as a published e-book. I read the whole of the text in the author's own PDF, start to finish, but with an automated text extraction, so the pictures, captions, layout and the last "Thanks" and "About the author" pages came through only in part. I did not read the TED Books app version, the Kindle or the 2022 re-issue. Everything else comes from catalog and store pages, TED's blog, and the interviews linked below. I read page text, not audio or video. No source note mentioned the book; I wrote this on request. ## 1. Book facts | | | |---|---| | Title | *Mind Amplifier: Can Our Digital Tools Make Us Smarter?* | | Author | Howard Rheingold (sole author) | | Publisher | TED Conferences, New York ("TED Books" series), e-book only. A second edition by Stillpoint Digital Press (a Smashwords and Kindle e-book) came out on Jan 19, 2022 with the same title and author | | First published | September 2012. OverDrive's title page gives the release date as 26 Sept 2012; TED's blog announced it on Sept 28, 2012 | | ISBN | 9781937382230 (e-book) for the 2012 TED edition, from a Free Library of Philadelphia catalog record that I saw only as a search snippet (the page itself returned an error to me). The 2022 Stillpoint edition is ISBN 9781005587963 (Smashwords and Amazon pages) | | Length | Not stated on the pages I could open. A reviewer (Cydcor) calls it "a quick 62-page read"; the author's PDF runs 85 pages including front matter, notes and images; Smashwords counts 14,727 words for the 2022 edition | | Language | English | | Audiobook | I found none. Audible's search page gave me an error, so this is unconfirmed | **License note.** The PDF's own front matter says the e-book and the author's portrait "are licensed under a Creative Commons Attribution 4.0 International License", except that other illustrations are "Copyright © 2012 by Shutterstock.com, all rights reserved" and used by permission. So the text is free to read and, with credit, to share. Check the license text itself before you reuse the pictures. **Where it came up.** It did not come from a source note. Marshall asked for it on 2026-11-03 as part of "all of Howard Rheingold's books". ## 2. Book resources **Free (legal).** - **Author-posted PDF: [rheingold.com/texts/Mind_Amplifier.pdf](https://rheingold.com/texts/Mind_Amplifier.pdf).** Howard Rheingold hosts it on his own site (also listed as "Mind Amplifier (PDF)" on his [Texts & Books page](https://www.rheingold.com/texts/)). It is the full text, 85 PDF pages, with the Creative Commons Attribution 4.0 notice described above. Wikipedia's list of his books also says the book is free as a PDF. This is the copy I read. - **Libby/OverDrive.** The [OverDrive title page](https://www.overdrive.com/media/1233602) exists (TED Conferences, released 26 Sept 2012, e-book) and offers a sample. It said "Title found at these libraries" with a list that never loaded for me, so I cannot tell you which libraries own it. Search your own library in Libby by title. - **Hoopla.** Its [search page](https://www.hoopladigital.com/search?q=mind%20amplifier) loads, but I could not see results from my box. Not confirmed. - **Internet Archive and Open Library.** My searches found no record for this title in either. Not confirmed either way beyond those searches. - **Project Gutenberg.** Not applicable; it is a 2012 book. **Paid.** - **Amazon/Kindle.** The [Kindle page for the 2022 Stillpoint second edition](https://www.amazon.com/Mind-Amplifier-Digital-Stillpoint-Rheingold-ebook/dp/B09QSYSCTQ) loads (ASIN B09QSYSCTQ). A search result snippet showed $4.99; I did not parse the page myself, so check the price. TED's blog says the 2012 edition was sold for Kindle, Nook and the iBookstore and in the TED Books app; I did not find that original listing. - **Smashwords:** [2022 edition](https://www.smashwords.com/books/view/1128121) (Stillpoint Digital Press; the page lists 14,727 words). I could not read the price. - **Audible:** none found. **Cover:** [OverDrive cover image](https://img1.od-cdn.com/ImageType-400/4083-1/AAE/AF3/32/%7BAAEAF332-857C-489E-B080-9F31B7B85CBE%7DImg400.jpg) (the 2012 TED edition record). ## 3. Author biography Howard Rheingold (born July 7, 1947, Phoenix, Arizona; Reed College; per Wikipedia) is an American writer, critic and teacher on the cultural, social and political effects of communication media. This book's own "About the author" page is cut off on the right in the PDF text I extracted, but legible parts say he wrote *Tools for Thought* and *Net Smart* (2012) (other titles are cut off), was editor of *Whole Earth Review* (the book mentions this again in its last chapter), editor of HotWired and founder of Electric Minds, and taught at Berkeley (2005-2007) and Stanford (2007-2012), and that he organizes the Peeragogy Project. In this book he also says he used a manual and then an electric typewriter for more than ten years as a professional writer before he "talked [his] way into a contractor job" at Xerox PARC that gave him access to the Alto. His site is [rheingold.com/howard](https://www.rheingold.com/howard); his [Wikipedia page](https://en.wikipedia.org/wiki/Howard_Rheingold) lists the rest of his bibliography. The vault has a dossier for his earlier book *Tools for Thought* (1985), which this one revisits. ## 4. Author interviews and talks - **TED Blog Q&A, "Mind Amplifier: New TED ebook author asks whether digital media can make us smarter" (Oct 2, 2012).** [Page](https://blog.ted.com/mind-amplifier-new-ted-ebook-author-asks-whether-digital-media-can-make-us-smarter/). The author explains the book in his own words: cultural evolution as the "add-ons" humans have invented and teach each other, the McLuhan line "we shape our tools, and then they shape us", and why to concentrate on how thought extension happens, both the cognitive and the technological sides. - **TED Blog announcement (Sept 28, 2012).** [Page](https://blog.ted.com/new-ted-book-mind-amplifier/). It embeds Rheingold's TED talk "The new power of collaboration" and describes the book as proposing "an applied, interdisciplinary science of mind amplification". I did not watch the talk; the [TED talk page](https://www.ted.com/talks/howard_rheingold_the_new_power_of_collaboration) loads. - **Humans + AI podcast with Ross Dawson (AC Ep3, July 25, 2023).** [Page](https://humansplus.ai/podcast/howard-rheingold-human-cooperation-origins-technology-enabled-mind-consciousness-amplification-ac-ep3/). I read the excerpt where Dawson asks about *Mind Amplifier*. Rheingold says he wanted to "zoom back and look at the greater context of Tools for Thought" and the long-term coevolution of humans, culture and tools, with writing as the example. I did not read the whole transcript. ## 5. Summary **Thesis.** The question in the opening chapter: instead of asking "whether the Web and the various devices connected to it are making us stupid", could we "mindfully design and use digital media to make us smarter"? Humans "invented social learning, speech, writing, alphabets, printing, computers, and the Internet", so we "should be systematically directing the evolution of intellectual augmentation." He says the root ideas are not his: he links the work of media historians, cognitive psychologists and computer visionaries into a framework. He also admits the risks, naming pollution, surveillance and nuclear weapons, and says he is not arguing for or against a "singularity". The question comes from Bush, Licklider and Engelbart (he also names Emanuel Goldberg and Paul Otlet "less successfully"), and he says it is time to "revive the original quest". **Chapter outline.** Headings come from the book's own table of contents, which lists no page numbers, so none are given here. The notes are from the text I read. 1. **Tools for the mind.** The thesis above, and the promise to look at "the tools they really are". 2. **Natural-born cyborgs.** Language sped human change up. Neuroscientist Stanislas Dehaene's "neuronal recycling" and neuroplasticity let humans reprogram brains and teach others to. Andy Clark's "natural-born cyborgs". He asks "What does it mean to be human?" as an engineering and bioethics issue. 3. **Augment, amplify, extend.** The term "cyborg" (Clynes and Kline, 1960) and his idea of "cyborg literacy", skills for using cognitive and physical technologies to augment thinking, with empathy and conviviality as well. He sets his enthusiasm against costs: Facebook's privacy, drones, conflict minerals. Ends with bulleted "ideas worth spreading" about the mind as a self-evolving organ. 4. **Co-evolving with our tools.** William Calvin's *The Throwing Madonna* (ballistic calculation reused for language), "exaptation", and co-evolution of humans, tools and culture. Attention, mirror neurons and joint attention as the root of culture; mindfulness and metacognition as clues for design. 5. **Inventing literacy.** Robin Dunbar's gossip and neocortex argument, Robert Logan's account of language origins, agriculture, Sumerian clay tokens and Denise Schmandt-Besserat's work on how writing emerged, then Maryanne Wolf and Dehaene on how reading changes brains, including Plato's warning about writing. 6. **The role of culture.** Cooperation as the biggest social "meta-tool" (Matt Ridley; Boyd, Henrich and Richerson on cultural evolution of cooperation; Dawkins and Blackmore on memes). Culture as an inheritance system with Darwinian dynamics and today's "a global civilization, highly interconnected, partially educated, and threatened by the unintended side effects of our own powerful inventions." 7. **The alphabet effect.** Logan, McLuhan and Innis on the alphabet as a mind-tool, and Eisenstein on the printing press and science as a collective enterprise. 8. **Computerized thinking tools.** Engelbart reads Bush's "As We May Think" in the Philippines; Licklider's "Man-Computer Symbiosis" and the ARPA office that funded interactive computing, Sutherland's graphics and Engelbart's lab. He stresses the military roots of computing ("Faustian origins") and calls personal computing "a cultural exaptation". 9. **Bootstrapping.** Engelbart's 1962 "Augmenting Human Intellect": humans, language, artifacts, methodology and training co-evolving, with long quotations. Rheingold's own typewriter-to-Alto word-processing story, and the question of what interdisciplinary mind-extension study would look like. 10. **Metacognition.** "Thinking about thinking" and its link to "infotention" and "crap detection" from his book *Net Smart*; search engines; Conati and VanLehn on computer support for self-explanation; and the suggestion that the automated tutoring and testing systems used for MOOCs could support self-reflection on learning, "a metacognition amplifier". 11. **Automating abstract thought.** Abstraction as chunking, starting from George Miller's paper "The Magical Number Seven, Plus or Minus Two"; "abstracting abstraction" from tiger concept to word to clay mark; Turing, Boole and Shannon's thesis; Logan's "fifth" and "sixth" languages; outliners and visualization as ways to climb abstraction hierarchies. 12. **Collaborative cognition.** A tweet exchange as an example, Ed Chi's "augmented social cognition", and why design gets harder when augmenting groups, with sociology, anthropology and economics added. 13. **Collective intelligence.** Examples: the search for Jim Gray, the Katrina PeopleFinder, Wikipedia, China's "human flesh search engines", SARS researchers, PatientsLikeMe, Foldit players, crisis mappers in Haiti, UK expense-report sleuths, and MIT's Center for Collective Intelligence. A course on mind extension should include a module on this. 14. **The power of many.** Ants, pheromones and "stigmergy", applied to Wikipedia, links and Google's PageRank; Chalmers and Clark's "extended mind" as a coupled human-tool system. 15. **A design for improved collective action.** Weizenbaum's caution that a tool amplifying only rational thought can do harm, Ivan Illich's "convivial tools", the need for digital literacy, and Elinor Ostrom's eight design principles for managing commons as thinking tools for designers. He says to keep Engelbart, Illich and Ostrom in mind together. 16. **A place to begin.** Metacognition, abstraction, augmented social cognition, collective intelligence and stigmergy as "entrances to mind-extension design", a list of global problems, and a closing call to "design our digital tools more mindfully". Followed by 77 endnotes (mostly "accessed Aug. 24, 2012"), thanks, a short author bio and a note on TED Books. **Reception (as reported by others).** Goodreads shows 3.59 average from 127 ratings across three editions (the page I opened on Nov 3, 2026). A Cydcor review (posted Aug 19, 2014, on a sales-outsourcing company's blog) calls it "an accessible overview" of online media and says the author "doesn't sugarcoat the digital age". A search snippet of the 2022 Amazon description quotes Anthony Wing Kosner of Forbes calling Rheingold a "digital elder"; I did not open the Forbes piece or the full description. I did not look for critical reviews, so this is not balanced. **Critical notes of my own.** The argument is a survey and a call to action, not a method: it names promising ideas and says they are "a beginning". It is mostly synthesis of other people's research, with few results of the author's own. Its examples date from 2012 and earlier. ## 6. Fact-check Overall verdict: **mostly supported**. Publication facts and the outline check out. The book itself contains a few small errors or loose claims, listed below. I did not check every claim in a text with 77 endnotes. | Claim | Verdict | Evidence | |---|---|---| | Published September 2012 as a TED Book | Supported | OverDrive release 26 Sept 2012; TED Blog posts of Sept 28 and Oct 2, 2012 | | ISBN 9781937382230 for the TED e-book | Partly checked | Seen only in a library catalog snippet; the page itself would not load for me | | Free author-posted PDF under CC BY 4.0 | Supported | The PDF's own front matter; the file loads from rheingold.com.

A search snippet of *The Atlantic*'s 2013 article (the page itself returned a 403) describes a Red Cross library in a hut with a thatched roof and says the copy was probably LIFE's abridgment. "August" looks too early | | Weizenbaum's *Computer Power and Human Reason* is "1968" in the text | Inconsistent | The book's own endnote 74 gives 1976; I did not look up a catalog record | | *Tools for Thought* published by MIT Press in 1999 (endnote 37) | Discrepancy | The MIT Press edition is dated 2000 in the catalog records I used for this vault's *Tools for Thought* dossier (not rechecked this run) | | Author's credits (*Net Smart*, 2012; *Whole Earth Review*; HotWired; Electric Minds; teaching at Berkeley and Stanford) | Supported as the book states them | The book's own "About the author" page (partly cut off in my extraction) | | "Cyborg" coined by Clynes and Kline in 1960; Gutenberg-era figures (30,000 vs 30 million books); Ostrom's eight principles; the study results in the endnotes | Not checked | I took these as the author states them | | Audiobook | Not found | Audible's search page gave me an error | | Library ebook availability | Unchecked | OverDrive's library list never loaded | ## 7.
