# The Law of Exclamation

The Law of Exclamation is an internet adage holding that a statement's credibility drops as its exclamation points multiply. The rule crystallized in 2008 after FactCheck.org flagged excessive bangers as a chain-email red flag, and a Rational Wiki entry that September gave the idea a name that stuck across skeptic blogs and later Internet law roundups.

## Origin
Suspicion toward multi-bang punctuation predates the law by more than a decade. In January 1997, IBM's antivirus research team published a lay-reader guide to spotting email virus hoaxes that explicitly flagged excessive exclamation points as a warning sign[4]. Later that year, IBM researcher Sarah Gordon presented a scientific paper titled 'Hoaxes and Hypes' at the 7th Virus Bulletin International Conference in San Francisco, which examined the same signals in more depth[5].

The specific 'law' formulation came together in 2008. In March of that year, FactCheck.org's Lori Robertson analyzed 31 chain emails about Barack Obama, Hillary Clinton, and Bill Clinton, found only two contained accurate claims, and listed overuse of exclamation points among seven red flags for suspicious messages[1]. The adage was submitted to Rational Wiki as the 'Law of Exclamation' that September[6].

## Overview
Writers invoke the Law of Exclamation to dismiss chain emails, fake Facebook profiles, padded hotel reviews, and any text leaning on walls of '!!!' for authority. The core claim is simple: real reporting rarely needs five bangers in a row to make its point, so a pile of exclamation marks reads as a tell for hype, hoax, or outright fabrication[1]. The rule gets paired with other credibility checks like missing sources, blocks of ALL CAPS, and 'forward this to ten friends' instructions[1].

The adage echoes older literary advice. Novelist Elmore Leonard allowed writers only two or three exclamation points per 100,000 words of prose, a quota he laid out in a 2001 New York Times essay on his rules of writing[2]. Terry Pratchett pushed the idea into fiction across his Discworld novels, where characters who overused the mark were depicted as unstable. His 1991 book Reaper Man delivers the often-quoted line, 'Five exclamation marks, the sure sign of an insane mind'[3].

## How to Use
The law is typically invoked as a one-line dismissal when debunking a post. A common convention is to quote the suspect text, note the exclamation-point count, and link to the Rational Wiki entry[6]. Writers often apply it alongside other hoax checks rather than on its own.
