The Book Of General Ignorance

What The Book Of General Ignorance Actually Is

The Book Of General Ignorance is a QI reference book written by John Lloyd and Tim Harford, published in 2006 by Pan Macmillan. It grew out of the BBC radio and television show QI, which stands for Quite Interesting. The book is structured as a dictionary of trivia, common misconceptions, and oddly specific facts arranged alphabetically by subject. Each entry runs a few paragraphs and typically starts with a widely held false belief, then explains what actually happened or what the evidence shows. I picked up the first edition around 2008 and read it straight through because I was between projects and it was an easy way to stay occupied. It's not a book you study. It's a book you flip through when you need to fill dead time or when someone at a pub quiz is about to say something confidently wrong.

The Book Of General Ignorance and How People Actually Use It

Most people treat it like a cocktail-party ammunition dump. They memorize three or four entries per sitting and wait for a social situation where they can deploy something about how the Great Fire of London was caused by a bakery in Pudding Lane killing Charles II's pet parrot. It works sometimes. It does not work well in academic settings because the entries are deliberately informal and the tone is jokey even when covering genuinely uncomfortable history. The structural approach is worth understanding before you waste time on it. Lloyd and Harford organize the content by topic rather than chronology. You will find entries under headings like "Animals," "Food and Drink," "History," "Language," and "Science." Within each section the facts are listed roughly in order of obscurity. The book does not attempt to be comprehensive. It attempts to be surprising. That is an important distinction because it means the book has blind spots and systematic gaps you should know about. I ran into a real problem with the first edition last year when I was preparing material for a radio segment about medieval food superstitions. The entry on "Salt" claimed that spilling salt brings bad luck because Judas sat at the left hand of Christ. That is one version of the myth. It is not the only version, and it is not well sourced in the book. I needed a secondary reference to verify the claim before going on air, and the book did not provide one. I ended up cross-checking with Barbara Evitts' work on salt superstitions and an entry in the Oxford Dictionary of Folklore. That is the sort of thing you learn to do after the first few editions.

The workaround I use now is simple. I treat the book as a lead generator, not a source. If an entry interests me, I take the claim, note the author's phrasing, and then look for at least one independent academic or archival reference. The book is excellent at pointing you toward a question. It is mediocre at giving you the answer you can cite in print. Budget thirty seconds per entry for verification if you plan to use any fact from it seriously.

How The Book Of General Ignorance Works In Practice

The entries are short. Most run between two and six paragraphs. Some are longer when the author thinks a topic deserves more unpacking, like the entry on "The British Empire" or "Tea." The writing style is conversational. Lloyd and Harford write like two people who have spent too many hours in newsrooms and radio studios. They know when to cut a sentence and when to let a joke land. They also know when to move on, which is why the book can feel scattered if you read it cover to cover. The format relies heavily on misdirection. An entry will often start with a bolded false statement, then spend the next paragraph dismantling it. This technique is useful because it trains you to question your own assumptions. It is less useful when the false statement is already something you knew was false, in which case you are reading a long explanation of a straw man. I have found the strongest entries are in the sections on language, food history, and British institutional quirks. The science entries are hit and miss. Some are solid, like the piece on zero and its messy history in European mathematics. Others feel rushed or rely on outdated scholarship. The 2006 publication date matters here. A lot of the science references are from the early nineties or late eighties, and several fields have moved on significantly since then.

One counter-intuitive insight most people miss is that the book is not actually designed to teach you things. It is designed to make you aware of how much you do not know. The title is the point. Reading it carefully will leave you with a lingering sense that your knowledge base is built on folklore, misattributed quotes, and a few lucky guesses. That is by design. The authors are playing a game, and the game is "what do normal people believe that turns out to be wrong?" Another thing beginners do not grasp is that the book is chronologically conservative. It favors older stories, British examples, and Western culture. If you are looking for global history or non-European perspectives, you will find them in small doses and often filtered through a very specific lens. The entry on "China" is a good example. It contains useful facts, but it also skips over entire periods and reduces complex topics to punchy anecdotes. That does not make the book useless. It makes it a poor primary reference for anything outside its comfort zone.

What To Expect Before You Read It

The book has weaknesses. I will list them plainly because you deserve to know them before you invest time in it. The first edition lacks citations. None. There are no endnotes, no bibliography, and no index in the traditional sense. The index exists but it is thin. You will waste time flipping between sections because the cross-referencing is minimal. The second and third editions improved this slightly, but they still do not meet academic standards for sourcing. The tone can be grating after a few hours. The authors lean on self-deprecation and gentle mockery of the reader. It works in short bursts. It does not work well as a sustained reading experience. I usually read it in twenty to thirty minute chunks and then put it down. Anything longer and I start skimming, which defeats the purpose of reading a book that rewards careful attention.

The content occasionally repeats itself across entries. Lloyd and Harford reuse certain myths and jokes because they work across multiple topics. The story about Napoleon's height appears in more than one place. The anecdote about Isaac Newton and the apple shows up in different contexts. This is not a bug. It is a feature of the format, but it means you are getting less unique material per page than the page count suggests. For people who want a more rigorous alternative, I would recommend pairing this book with works like Mark Forsyth's The Etymologiaicon or Judith Flanders' The Victorian House. Those books cover similar ground with better sourcing and deeper research. They are also more expensive and less entertaining on a casual level. The trade-off is real. If you want a copy of The Book Of General Ignorance, it is available through most major booksellers and used-book sites. The first edition is still in print in paperback and can be found for around twelve to eighteen pounds depending on condition and seller. Digital versions exist through Amazon Kindle and Apple Books. Library copies are usually available through interlibrary loan if you do not want to buy it.

I keep mine on a side table. I reach for it when I need background noise for a dull evening or when I want to kill forty minutes without scrolling through my phone. It is not the best reference book you can own. It is not the worst. It is a decent companion for people who enjoy learning things they will never need in their actual lives, which is honestly the best reason to read anything.
