This Style Guide describes the stylistic rules to which all EA Wiki articles should conform. We are definitely happy for you to begin contributing to the Wiki without having learned these rules. We would much rather have good content we need to reformat than no content at all, and we are grateful for your contributions either way.
The document is heavily based on Wikipedia's Manual of Style, and a few parts of it are directly copied from that article. However, it also deviates from it in a number of respects, and is considerably shorter. If you are broadly familiar with Wikipedia's conventions already, you may want to skim liberally and just focus on the sections that present you with new information.
The Style Guide is a work in progress, and it will be revised and expanded over time. If you have questions about matters of style not answered by this document, or answered inadequately, feel free to make an edit or leave a comment.
The title of an article should be a precise, concise and recognizable name or description of the topic of the article. Use sentence case, and avoid articles at the beginning and punctuation marks at the end, unless doing so would result in the removal of an inseparable part of the name.
History of effective altruism
The history of effective altruismThe Life You Can Save
Life You Can Save
If the title is a name that has an associated acronym, use the acronym only if that is how the subject is primarily known.
ALLFED
Animal Charity Evaluators
ACE
In general, give preference to the singular over the plural:
existential risk
existential risks
If the title involves a conjunction, use "and" rather than an ampersand (&).
Begin every article with a lead section, or a summary of the subject, followed by a body.
The first sentence of the lead should contain a definition of the topic of the article. The title of the article should appear in this sentence, in boldface.
GiveWell is a nonprofit charity evaluator based in San Francisco.
If relevant, include alternative or former terms or spellings for the topic in parentheses. These variants should also be boldfaced.
Open Philanthropy (previously the Open Philanthropy Project) is a research and grantmaking foundation based in San Francisco.
Divide the body, but never the lead itself, into sections. Each section may be further subdivided into subsections, as needed.
The sections of the body may be followed, when appropriate, with the sections Further reading, External links and Related entries, in that order. See here and here for examples.
Each section in the article, except the lead section, is associated with a section heading. When naming headings, follow the same rules as govern the naming of titles.
Write in an encyclopedic tone. Avoid slang, colloquialisms, legalese or unnecessary jargon. Do not write from a first- or second-person perspective. Avoid bombastic wording, innuendo, humor, or irony.
Entries should adopt a neutral point of view rather than advocate for a particular point of view. If controversy exists, do not take sides; rather, summarize the relevant views, and the evidence and arguments presented in their favor, fairly and accurately.
Avoid stating as facts claims that would be disputed by someone endorsing reasonable epistemic standards. Conversely, avoid presenting a claim that would pass the above test as a mere subjective opinion.
Avoid making value judgments. If contextually relevant, you may describe value judgments made by others, but never in a way that suggests endorsement.
When differences in spelling, vocabulary or grammar exist between different national varieties of English, you are free to use whichever variant corresponds to the variety of English you speak, or that you prefer for any other reason. However, this is subject to the following qualifications:
Write words in full when they first occur in the article, mentioning the abbreviation in parenthesis, unless an abbreviation is so familiar that it is used more often in full.
The BBC
The British Broadcasting Corporation
Use the abbreviated form throughout the rest of the article, but also consider alternative ways of referring to the entity in question to avoid unnecessary proliferation of capital letters.
The terms 'effective altruism', 'existential risk' and other expressions commonly abbreviated in informal discussion should be spelled in full and—unless they occur as part of a name—in lowercase.
Criticism of EA
The Effective Altruism movement
anthropogenic x-riskThe Centre for Effective Altruism
The Centre for the Study of Existential Risk
As noted in the Organization of articles section, the article's title, as well as variant spellings, should appear in boldface. Otherwise, you should use only italics—rather than boldface or capitals—for emphasis.
The use of italics for citing works is covered in References.
Enclose short quotations in double quotation marks, and use block quotations for longer quotations. We consider a quotation short if it consists of less than one full paragraph and at most 40 words, and longer otherwise.
For short quotations, the citation should follow the quotation.
In Jan Naverson's famous dictum, "We are in favor of making people happy, but neutral about making happy people."[1]
For long quotations, the citation should precede it.
Derek Parfit has expressed a version of this view :[2]
>If we are the only rational beings in the Universe, as some recent evidence suggests, it matters even more whether we shall have descendants or successors during the billions of years in which that would be possible. Some of our successors might live lives and create worlds that, though failing to justify past suffering, would have given us all, including those who suffered most, reasons to be glad that the Universe exists.
To keep the length of this document within reasonable boundaries, there are many punctuation rules we do not cover here. We just focus on the most important rules, or those where we expect most uncertainty to exist. Please refer to the corresponding section of Wikipedia's manual of style for further details.
Use logical punctuation, always keeping periods and commas inside the quotation marks when they are meant to apply to the quoted material.
Steven Pinker says you should use logical punctuation "if you write for Wikipedia or another tech-friendly platform", or "if you have a temperament that is both logical and rebellious".
When a quotation occurs inside another quotation enclosed in quotation marks, use single quotes for the inside quotation. Otherwise always use double quotes.
The EA Wiki Style Guide should really stop trying to be funny by using examples such as "Steven Pinker encourages the use of logical punctuation [...] 'if you have a temperament that is both logical and rebellious'."
As illustrated by the above example, inessential parts of a quotation may be omitted by enclosing the ellipsis in square brackets.
The use of serial commas is typically optional. However, serial commas should be either used or avoided when this is necessary to avoid syntactic ambiguity.
This book is dedicated to my parents, Ayn Rand and God.This book is dedicated to my parents, Ayn Rand, and God.
To mark divisions within a sentence, either singly or in pairs (parenthetical dashes), use em dashes (—) with no spaces on either side.
you should use only italics—rather than boldface or capitals—for emphasis
To insert an em dash on MacOS, press Option-Shift-Hyphen; to do so on Windows, type 0151 while holding Alt. You can also use a shortcut application like AutoControl Shortcut Manager or AutoHotkey to make this punctuation easier to access.
Write dates in the formats "1 January 2021" (full date), "January 1" (month and day), and "January 2021" (month and year). Do not write "1st", "2nd", and so on. Note that the separator is always a space and never a comma.
For decades, use "the 1920s" rather than "the '20s".
For the current date, use "As of January 2021" or "As of 1 January 2021", replacing the dates in the examples by the current date.
As of January 2021, Giving What We Can has 5,600 members.
Use either a 12-hour clock or a 24-hour clock. Twelve-hour clock times are written in the form 8:15 am and 2:30 pm. Twenty-four-hour clock times are written in the form 08:15 and 14:30.
If the time zone is relevant, use Coordinated Universal Time. You may also specify the number of seconds, using a 24-hour clock.
The first nuclear device was detonated on 16 July 1945 at 11:29:45 UTC.
Spell integers from zero to nine in words. Integers greater than nine expressible in one or two words may be spelled in either words or numerals.
There are four main cause areas in effective altruism.
Good Ventures has given over $1.25 billion in grants.
Do not abbreviate "thousand", "million", "billion" and "trillion".
For ranges—including date and page ranges—use an en dash (–). To insert an en dash on MacOS, press Option-Hyphen; to do so on Windows, type 0150 while holding Alt. You can also use a shortcut application like AutoControl Shortcut Manager or AutoHotkey to make this punctuation easier to access.
For large numbers, use scientific notation.
what hangs in the balance is at least 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 human lives (though the true number is probably larger).What hangs in the balance is at least 1058 human lives (though the true number is probably larger).
Unless the context requires the use of a different currency, express amounts of money in United States dollars, euros, or pounds sterling, and indicate the currency by the symbols $, € and £, respectively. Use only one symbol with ranges separated by a dash, and do not insert a space between the symbol and the number.
A donation of $3000–5000 to the Against Malaria Foundation can avert the death of a child under five.
For other currencies, use ISO 4217 codes. The code should precede the currency amount, with a space separating the two.
Use the metric system and, more generally, the International System of Units and the accepted Non-SI units. Unit names should be given in full if used only a few times, but symbols may be used when a unit (especially one with a long name) is used repeatedly after spelling out the first use. Do not insert a period after the symbol, unless a period is required for other reasons. Use "per" when writing out a unit, rather than a slash.
For mathematical symbols, consider using LaTeX. You can use Ctrl-4 (Windows) or Cmd-4 (Mac) to open a LaTeX prompt in the Forum’s editor. Otherwise
Avoid contractions. Use "is not", "cannot", "will not" instead of "isn't", "can't", and "won't", etc.
Use gender-neutral language. To avoid generic masculine and generic feminine pronouns, consider the following approaches:
Some Forum users have suggested using the singular they. Reference works do not have a consistent position on this, so we tentatively leave the decision to the discretion of contributors. If you have suggestions concerning gender-neutral language, please leave them in the comments below.
Internal links are links to other articles of the Wiki. As a general rule, if a term occurs for which there is a Wiki entry, or refers to the topic of an entry without explicitly mentioning it, you should link to this entry. However, you should not create an internal link if this would result in repeated links to the same article within the span of a few paragraphs or so. In these cases, readers are likely to have already been exposed to that link, so there is no need to add another one.
External links are all links other than internal links. They include links both to other websites, and to pages within effectivealtruism.org that are not Wiki articles.
External links should only be used in the Further reading and External links sections of the article, and in footnotes, but never in the lead or body sections (see the Organization of articles section).
In the External links section, add links each in a separate line. The title of the link should be the name of the webpage to which the link points. Next to the title, add a brief description of that link; often, the description should just be "official website". See here and here for examples.
This section should list the entries most closely related to the topic of the article. If an entry is already linked to in the body of the article, you may still include it in this section, provided that it is sufficiently related.
Names should be listed in lowercase, in alphabetical order, and separated by a vertical bar (|) with spaces on either side. Do not add a period after the final entry. See here and here for examples.
Formatting citations can be quite time-consuming. We do not require contributors to format citations properly: you are only asked to provide the minimal details necessary to identify the relevant work, and we will deal with the rest. Alternatively, you can add citations in the appropriate format, without having to format them manually, by using the Wiki's associated Citation Language File, as explained here.
Citations in a Wiki article have two parts: first, a footnote number next to the text that is being quoted or referenced; and, second, a footnote where the details of the work are provided in full.
Footnote numbers should immediately follow the text for which the citation is provided. This is typically a clause, a sentence or a paragraph, or the elements of a range or an enumeration.
In its current form, the technology was first described by Carl Shulman in 2009,[3] and the idea was further developed in a 2014 paper by Shulman and Nick Bostrom.[4]
Public approval for preimplantation genetic diagnosis for intelligence has been found to range from 13%[5] to 19%[6] to 28%[7].
Multiple references should be separated using individual footnote numbers corresponding to each of them.
At around that time, while preparing to transition from journalism to philanthropy, Tuna read Peter Singer's The Life You Can Save, which introduced her "to the idea of not just trying to do some good with your giving, but doing as much good as you can."[8][9][10]
Footnotes should provide the details of the works cited. When possible, specify the relevant page, chapter, or section numbers. When referring to pages, use abbreviations "p." or "pp." When chapters are being referred to, indicate that by using the abbreviations "ch."/"chs."
Just as one may wonder why undesired dystopias would exist, one may wonder why desired dystopias would be dystopian. Here a relevant example has been provided by Nick Bostrom.[11][12]
