Lumber Cartel

Lumber Cartel is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Lumber Cartel rather than just read about it. In short: The Lumber Cartel was a facetious conspiracy theory popularized on USENET that claimed anti-spammers were secretly paid agents of lumber companies. In November 1997, a participant on news.admin.net-abuse.email posted an essay to the newsgroup.

Key takeaways

Lumber Cartel belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Lumber Cartel to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Lumber Cartel from memory before moving on to harder problems.

Reference excerpt

The Lumber Cartel was a facetious conspiracy theory popularized on USENET that claimed anti-spammers were secretly paid agents of lumber companies. In November 1997, a participant on news.admin.net-abuse.email posted an essay to the newsgroup. The essay described a conspiracy theory:

The original anti-spammer was in truth a major spammer just one day before two major lumber companies deposited a total of $275,000 into his account. He instantly stopped spamming and began what is now the biggest anti-spam ring on the Internet. The reasoning provided in the essay was that certain companies first destroy forests and make paper out of them, which is in turn used to send bulk mail. Since sending e-mail spam does not use paper at all, the essay argued, the lumber companies would want to stop it before it would surpass paper-based bulk mailing, and consequently only those in the pay of the lumber companies would be anti-spam. The rationale was based in disclaimers in certain spam messages that they were using electronic means in order to save paper. The joke eventually led to a club and numerous parody websites, most of which have long since disappeared. Gatherings of anti-spammers on Usenet began to ridicule proponents of this theory, and many participants in news.admin.net-abuse.email chose to dub themselves as members of "the Lumber Cartel" in their signatures, followed immediately by the acronymic disclaimer "TinLC" (There is no Lumber Cartel), reminiscent of the There Is No Cabal catchphrase. People were able to register with a website about the Lumber Cartel and were given a sequential membership number. That was added to email sig files in news.admin.net-abuse.email and used on personal websites. There was no verification or requirement to receive the membership number.

Worked examples

Example 1 — a first encounter with Lumber Cartel

Start with the simplest possible case. Write down what Lumber Cartel claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lumber Cartel before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lumber Cartel ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lumber Cartel

In research: Lumber Cartel appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Lumber Cartel in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Lumber Cartel is common in secondary-school and first-year university syllabi. It links to neighbouring topics Email, Internet hoaxes, Internet memes introduced in 1997, so understanding it makes those chapters shorter.
In everyday life: Look for Lumber Cartel outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
