I’ve long been fascinated by eponymous “laws”—those pithy, often sarcastic observations or rules of thumb that capture some universal truth of human experience. Murphy’s Law is probably the most well-known example.
Murphy’s Law: “Anything that can go wrong will go wrong.”
There are many lists of these laws online, but they are all deficient in one way or another (e.g. woefully lacking in comprehensiveness or including various scientific/technical laws which are not really in the same spirit as the more observational variety). What follows is, as far as I can tell, the most complete list of eponymous laws ever compiled by anyone ever (192 total).
A few notes:
Many non-eponymous laws/principles/effects/etc. in the same spirit as their eponymous brethren have also been included.
See Dave Kerr’s list of hacker laws for some laws/principles/effects/etc. that were a little too technical to warrant inclusion.
For ease of perusal, the list is divided into three categories: Internet Laws, Computer Laws, and Miscellaneous.
Enjoy!
Internet Laws
Armstrong’s Law: “The phenomenon observed in discussions between Americans and non-Americans where any mention of America not being the best in the world at something dramatically increases the likelihood of the American arbitrarily bringing up the US moon landings as a non-sequitur to prove America’s superiority.”
Badger’s Law: “Any website with the word ‘Truth’ in the URL has none in the posted content.” (see also: Haig’s Law)
Brandolini’s Law: “The amount of energy needed to refute bullshit is an order of magnitude larger than to produce it.”
Brown’s Corollary: “On the Internet, nobody knows you’re a dog, but everybody knows if you’re a jerk.”
CAD’s Theorem of Topic Closure: “A clear, well thought-out, well-written post is less likely to receive a reply than a shitty, moronic, badly mistaken post, because it leaves less to be said. A really full and comprehensive post may even appear to bring the conversation to a screeching halt.”
Cohen’s Law: “Whoever resorts to the argument that ‘whoever resorts to the argument that…has automatically lost the debate’ has automatically lost the debate.”
Conservation of Intelligence: “For a well-thought-out post, the longer it is and the more sources it cites, the more likely replies to it will consist of only one sentence that dismisses the entire argument through use of a straw man and/or logical fallacy, usually both.”
Cunningham’s Law: “The best way to get a correct answer to a posed question is to post the wrong answer and wait for someone to correct you.”
Danth’s Law: “If you have to insist that you’ve won an internet argument, you’ve probably lost badly.”
DarkShikari’s Theorem: “Any community that gets its laughs by pretending to be idiots will eventually be flooded by actual idiots who mistakenly believe that they're in good company.”
DeMyer’s Second Law: “Anyone who posts an argument on the internet which is largely quotations can be very safely ignored, and is deemed to have lost the argument before it has begun.”
First Law of Discussion Non-Response Bias: “Discussions tend to attract those with strong opinions, because moderates are less likely to make an effort to give their opinions.”
Godwin’s Law: “As an online discussion grows longer, the probability of a comparison involving Hitler approaches 1.”
Haig’s Law: “The awfulness of a website’s design is directly proportional to the insanity of its contents and creator.” (see also: Badger’s Law)
Illusions of Grandeur Principle: “The more someone calls attention to their talents, the less they will accomplish with them.”
Inverse Attraction Effect: “When someone starts a thread seeking fans of something (ex. ‘Who else here likes Twilight?’) on a forum not devoted to that thing, the thread is going to primarily attract people who dislike it and would like to tell the original poster about that. The reverse is also true (e.g. ‘Who else thinks anime is too popular?’ will rally the fans).”
John Gabriel’s Greater Internet Fuckwad Theory: “Normal Person + Anonymity + Audience = Total Fuckwad.”
Jordy’s Law: “Discussions aren’t settled on the internet, it continues until there is one man standing.” (Alternatively: “Discussions on the internet are a battle royale. The person left probably thinks he won the argument, the people who quit probably thought it wasn't worth the effort.”)
Law of Exclamation: “The more exclamation points used in an email (or other posting), the more likely it is a complete lie. This is also true for excessive capital letters.”
Law of Fakery: “Anything fake which attracts enough attention will have some people vehemently proclaiming it’s real. Anything real which attracts enough attention will have some people vehemently proclaiming it’s fake. (Corollary: If the creator confesses that it was fake, some people will still claim it’s real and call the confession a fake.)”
Law of Go FAQ Yourself: “People will repeat a question answered in a given forum’s FAQ at least once a week.”
Layne’s Law(s): “A) Every debate is over the definition of a word, B) every debate eventually degenerates into debating the definition of a word, or C) once a debate degenerates into debating the definition of a word, the debate is debatably over.”
Lewis’ Law: “The comments on any article about feminism justify feminism.”
Martin’s Law: “If during an online argument anyone accuses their interlocutor of living in their parents’ basement, the argument is over and the accuser has lost.”
Munroe’s Law: “You will never change anyone's opinion on anything by making a post on the Internet. Knowing this will not stop you from trying.”
Muphry’s Law (also known as Hartman’s Law of Prescriptivist Retaliation): “Any article or statement about correct grammar, punctuation, or spelling is bound to contain at least one eror.”
Poe’s Law: “Without a winking smiley or other blatant display of humour, it is impossible to create a parody of fundamentalism that someone won’t mistake for the real thing.” (see also: Poppy’s Law)
Pommer’s Law: “A person’s mind can be changed by reading information on the internet. The nature of this change will be from having no opinion to having a wrong opinion.”
Poppy’s Law: “There are sincere posts by fundamentalists so absurd that they are likely to be mistaken for satire.” (see also: Poe’s Law) (h/t Joe Hughson in the comments)
Reed’s Law: “The utility of large networks, particularly social networks, scales exponentially with the size of the network.”
Shaker’s Law of Departure: “Those who egregiously announce their imminent departure from an Internet discussion forum almost never actually leave.”
Shank’s Law: “There is no idea so batshit insane that you can’t find at least one PhD scientist to support it.”
Skarka’s Law: “On internet message boards, there is no subject so vile or indefensible that someone won’t show up and defend it.”
Skitt’s Law: “Any post correcting an error in another post will contain at least one error itself” or “the likelihood of an error in a post is directly proportional to the embarrassment it will cause the poster.” (see also: Muphry’s Law)
Streisand Effect: “The phenomenon whereby an attempt to hide, remove, or censor a piece of information has the unintended consequence of publicizing the information more widely, usually facilitated by the Internet.”
“Thanks for Nothing” Effect: “If the original post in a thread ends with the sentence ‘Thanks in advance!’ it is exponentially less likely that it will be replied to.”
Theory of Internet Relativity: “The more frequently you click ‘refresh’ on a given site, the less frequently new content will appear therein.”
Time Cube Law: “As the length of a webpage grows linearly, the likelihood of the author being a lunatic increases exponentially.”
Wadsworth Constant: “The first 30% of any video can be skipped because it contains no worthwhile or interesting information.”
You Broke It Rule: “A new thread with a first reply which is severely off-topic or lacking in content is not likely to see an improvement.”
Computer Laws
Bradley’s Bromide: “If computers get too powerful, we can organize them into a committee — that will do them in.”
Brooks’ Law: “Adding manpower to a late software project makes it later.”
Conway’s Law: “Any piece of software reflects the organizational structure that produced it.” Or… “Organizations which design systems are constrained to produce designs which are copies of the communication structures of these organizations.”
Dead Sea Effect: “The more talented and effective IT engineers are the ones most likely to leave (to evaporate); the residue—those who remain behind—are the least talented and effective IT engineers.”
Eagleson’s Law: “Any code of your own that you haven’t looked at for six or more months might as well have been written by someone else.”
Flon’s Law: “There does not now, nor will there ever, exist a programming language in which it is the least bit hard to write bad programs.”
Hartree’s Law: “Whatever the state of a project, the time a project-leader will estimate for completion is constant.”
Hoare’s Law of Large Programs: “Inside every large program is a small program struggling to get out.”
Jakob’s Law of the Internet Use Experience: “Users spend most of their time on other sites. This means that users prefer your site to work the same way as all the other sites they already know.”
Kerchkhoff’s Principle: “In cryptography, a system should be secure even if everything about the system, except for a small piece of information – the key – is public knowledge.”
Kernighan’s Law: “Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it.”
Knuth’s Optimization Principle: “Premature optimization is the root of all evil.”
Law of Demeter: “Don’t talk to strangers.” (A unit of software should talk only to its immediate collaborators.)
Linus’ Law: “Given enough eyeballs, all bugs are shallow.”
Mooer’s Law: “An information retrieval system will tend not to be used whenever it is more painful and troublesome for a customer to access information than for him not to have it.”
Moravec’s Law: “It is comparatively easy to make computers exhibit adult-level performance in solving problems, but difficult to give them the skills of a one-year-old in sensorimotor tasks.”
Ninety-Ninety Rule: “The first 90% of the code takes 90% of the time. The remaining 10% takes the other 90% of the time.”
Postel’s Law: “Be conservative in what you send, be liberal in what you accept.” (In other words, programs that send messages to other machines (or to other programs on the same machine) should conform completely to the specifications, but programs that receive messages should accept non-conformant input as long as the meaning is clear.)
Weinberg’s Law: “If builders built buildings the way programmers wrote programs, the first woodpecker that came along would destroy civilization.”
Wirth’s Law: “Software gets slower faster than hardware gets faster.” (cf. Moore’s Law)
YAGNI (You Aren’t Gonna Need It): “Always implement things when you actually need them, never when you just foresee that you need them.”
Miscellaneous
Dave Akin has a list of 45 laws derived from his experience as an aerospace engineer. All are included for sake of completeness.
Akin’s 1st Law: “Engineering is done with numbers. Analysis without numbers is only an opinion.”
Akin’s 2nd Law: “To design a spacecraft right takes an infinite amount of effort. This is why it’s a good idea to design them to operate when some things are wrong.”
Akin’s 3rd Law: “Design is an iterative process. The necessary number of iterations is one more than the number you have currently done. This is true at any point in time.”
Akin’s 4th Law: “Your best design efforts will inevitably wind up being useless in the final design. Learn to live with the disappointment.”
Akin’s 5th Law (a.k.a. Miller’s Law): “Three points determine a curve.”
Akin’s 6th Law (a.k.a. Mar’s Law): “Everything is linear if plotted log-log with a fat magic marker.”
Akin’s 7th Law: “At the start of any design effort, the person who most wants to be team leader is least likely to be capable of it.”
Akin’s 8th Law: “In nature, the optimum is almost always in the middle somewhere. Distrust assertions that the optimum is at an extreme point.”
Akin’s 9th Law: “Not having all the information you need is never a satisfactory excuse for not starting the analysis.”
Akin’s 10th Law: “When in doubt, estimate. In an emergency, guess. But be sure to go back and clean up the mess when the real numbers come along.”
Akin’s 11th Law: “Sometimes, the fastest way to get to the end is to throw everything out and start over.”
Akin’s 12th Law: “There is never a single right solution. There are always multiple wrong ones, though.”
Akin’s 13th Law: “Design is based on requirements. There’s no justification for designing something one bit ‘better’ than the requirements dictate.”
Akin’s 14th Law (a.k.a. Voltaire’s Law): “Better” is the enemy of “good”.
Akin’s 15th Law (a.k.a. Shea’s Law): “The ability to improve a design occurs primarily at the interfaces. This is also the prime location for screwing it up.”
Akin’s 16th Law: “The previous people who did a similar analysis did not have a direct pipeline to the wisdom of the ages. There is therefore no reason to believe their analysis over yours. There is especially no reason to present their analysis as yours.”
Akin’s 17th Law: “The fact that an analysis appears in print has no relationship to the likelihood of its being correct.”
Akin’s 18th Law: “Past experience is excellent for providing a reality check. Too much reality can doom an otherwise worthwhile design, though.”
Akin’s 19th Law: “The odds are greatly against you being immensely smarter than everyone else in the field. If your analysis says your terminal velocity is twice the speed of light, you may have invented warp drive, but the chances are a lot better that you’ve screwed up.”
Akin’s 20th Law: “A bad design with a good presentation is doomed eventually. A good design with a bad presentation is doomed immediately.”
Akin’s 21st Law (a.k.a. Larrabee’s Law): “Half of everything you hear in a classroom is crap. Education is figuring out which half is which.”
Akin’s 22nd Law: “When in doubt, document. (Documentation requirements will reach a maximum shortly after the termination of a program.)”
Akin’s 23rd Law: “The schedule you develop will seem like a complete work of fiction up until the time your customer fires you for not meeting it.”
Akin’s 24th Law: “It’s called a ‘Work Breakdown Structure’ because the Work remaining will grow until you have a Breakdown, unless you enforce some Structure on it.”
Akin’s 25th Law (a.k.a. Bowden’s Law): “Following a testing failure, it’s always possible to refine the analysis to show that you really had negative margins all along.”
Akin’s 26th Law (a.k.a. Montemerlo’s Law): “Don’t do nuthin’ dumb.”
Akin’s 27th Law (a.k.a. Varsi’s Law): “Schedules only move in one direction.”

Akin’s 29th Law (a.k.a. von Tiesenhausen’s Law of Program Management): “To get an accurate estimate of final program requirements, multiply the initial time estimates by pi, and slide the decimal point on the cost estimates one place to the right.”
Akin’s 30th Law (a.k.a. von Tiesenhausen’s Law of Engineering Design): “If you want to have a maximum effect on the design of a new engineering system, learn to draw. Engineers always wind up designing the vehicle to look like the initial artist’s concept.”

Akin’s 40th Law (a.k.a. McBryan’s Law): “You can’t make it better until you make it work.”
Akin’s 41st Law: “There’s never enough time to do it right, but somehow, there’s always enough time to do it over.”
Akin’s 42nd Law: “If there’s not a flight program, there’s no money. If there is a flight program, there’s no time.”
Akin’s 43rd Law: “You really understand something the third time you see it (or the first time you teach it).”
Akin’s 44th Law (a.k.a. Lachance’s Law): “‘Plenty of time’ becomes ‘not enough time’ in a very short time.”
Akin’s 45th Law: “Space is a completely unforgiving environment. If you screw up the engineering, somebody dies (and there’s no partial credit because most of the analysis was right...).”
Acton’s Dictum: “Power tends to corrupt, and absolute power corrupts absolutely.”
Amara’s Law: “We tend to overestimate the effect of a technology in the short run and underestimate the effect in the long run.”
Barrow’s First Law: “Any universe simple enough to be understood is too simple to produce a mind able to understand it.”
Benford’s Law: “In many naturally occurring collections of numbers, the leading significant digit is likely to be small.” (For example, in sets that obey the law, the number 1 appears as the most significant digit about 30% of the time, while 9 appears as the most significant digit less than 5% of the time. If the digits were distributed uniformly, they would each occur about 11.1% of the time.)
Benford’s Law of Controversy: “Passion is inversely proportional to the amount of real information available.”
Betteridge’s Rule: “98% of leading or speculative questions in thread titles can be correctly answered, ‘No’.”
Box’s Law: “All models are wrong, but some are useful.”
Campbell’s Law: “The more any quantitative social indicator is used for social decision-making, the more subject it will be to corruption pressures and the more apt it will be to distort and corrupt the social processes it is intended to monitor.” (see also: Goodhart’s Law)
Celine’s 1st Law: “National Security is the chief cause of national insecurity.”
Celine’s 2nd Law: “Honest communication occurs only between equals.”
Celine’s 3rd Law: “An honest politician is more dangerous than a corrupt one.”
Chesterton’s Fence: “Reforms should not be made until the reasoning behind the existing state of affairs is understood.”
Clarke’s 1st Law: “When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.”
Clarke’s 2nd Law: “The only way of discovering the limits of the possible is to venture a little way past them into the impossible.”
Clarke’s 3rd Law: “Any sufficiently advanced technology is indistinguishable from magic.”
Gehm’s Corollary: Any technology distinguishable from magic is insufficiently advanced.
Heterodyne’s Inversion: “Any sufficiently well-understood magic is indistinguishable from technology.”
Ambrose’s Appendix: “Any technology, no matter how primitive, is magic to those who don't understand it.”
Cleek’s Law: “Today’s conservatism is the opposite of what liberals want today, updated daily.”
Cole’s Law: “A salad made with thinly-sliced or shredded cabbage. It can include carrots, and is often made with vinegar or a vinaigrette. In the United States, it is often made with mayonnaise.”
Collingridge’s Dilemma: “Technology can only be regulated well if its impacts are known, but once a technology is known it is often too entrenched to be regulated.”
Conquest’s First Law: “Everyone is conservative about what he knows best.”

Dawkins’ Law of the Conservation of Difficulty: “The easier an academic field, the more it will try to preserve its difficulty by using complex jargon.”
Dilbert Principle: “Companies are hesitant to fire people but also want to not let them hurt their business, so companies promote incompetent workers into the place where they can do the least harm: management.” (see also: Putt’s Law.)
Dykstra’s Law: “Everybody is somebody else’s weirdo.”
Ebert’s Law: “It’s not what it's about, it's how it’s about it.”
Gall’s Law: “A complex system that works is invariably found to have evolved from a simple system that worked. The inverse proposition also appears to be true: A complex system designed from scratch never works and cannot be made to work. You have to start over, beginning with a working simple system.”
Gibson’s Law: “For every PhD there is an equal and opposite PhD.”
Golden Law of Stupidity: “A stupid person is a person who causes losses to others while themselves deriving no gain and even possibly incurring losses.”

Iron Law of Oligarchy: “All forms of organization, regardless of how democratic they may be at the start, will eventually and inevitably develop oligarchic tendencies, thus making true democracy practically and theoretically impossible, especially in large groups and complex organizations.”
Joy’s Law: “No matter who you are, most of the smartest people work for someone else.”
KISS Principle: “Keep it simple, stupid.”
Kranzburg’s First Law of Technology: “Technology is neither good nor bad; nor is it neutral.”
Law of Image Overcompensation: “The amount of effort a person, group, or organization puts into projecting any image for themselves is inversely proportional to how accurate that image is. This is especially true of politicians and advertising campaigns. For example, it’s always the biggest homophobes who turn out to be Armoured Closet Gay. Likewise, the ‘pro-family’ politicians are always the ones who have been cheating on their spouses, and ‘this is not your grandfather’s car’ means it most definitely is your grandfather’s car.”
Law of the Instrument: “If all you have is a hammer, everything looks like a nail.”
Lincoln’s Law: “If a country or group’s name has the word ‘People’s’ in it, it will have nothing to do with either democracy or The People.”

Lizard’s Law: “People fuck everything.” (source; h/t Sintana in the comments)
Martec’s Law: “Technology changes exponentially, but organizations change logarithmically.”
Matthew Effect: “The rich get richer, the poor get poorer.” (Eminent scientists will often get more credit than a comparatively unknown researcher, even if their work is similar; also, credit will usually be given to researchers who are already famous.)
Mencken’s Law (a.k.a. Shaw’s Law): “Those who can, do. Those who cannot, teach.”
Martin’s Extension: Those who cannot teach, teach education (or teach teachers; or administrate).

Parkinson’s Law: “Work expands so as to fill the time available for its completion.”
Parkinson’s Law of Triviality (a.k.a. Bike-shedding): “Members of an organization give disproportionate weight to trivial issues.” (Parkinson provides the example of a fictional committee whose job was to approve the plans for a nuclear power plant spending the majority of its time on discussions about relatively minor but easy-to-grasp issues, such as what materials to use for the staff bike shed, while neglecting the proposed design of the plant itself, which is far more important and a far more difficult and complex task.)
Peter Principle: “In a hierarchy, every employee tends to rise to his level of incompetence.” (see also: the Dilbert Principle.)
Planck’s principle: “A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it.”
Platt’s Law of AI Forecasting: “Any AI forecast will put strong AI thirty years out from when the forecast is made.”
Pournelle’s Iron Law of Bureaucracy: “In any bureaucracy, the people devoted to the benefit of the bureaucracy itself always get in control and those dedicated to the goals that the bureaucracy is supposed to accomplish have less and less influence, and sometimes are eliminated entirely.”
Putt’s Law: “Technology is dominated by two types of people, those who understand what they do not manage and those who manage what they do not understand.”
Ringelmann Effect: “Individuals becoming increasingly inefficient as more and more people become involved in a task.” (see also: Brooks’ Law.)

Akin's Laws are another classic set
Gresham's Law: bad money drives out good money.
One I heard I the Navy: the acceptance of every new idea goes through three steps:
Someone thinks it up.
Someone makes it widely known.
We wait for all the old men to die.
