Quackdown

Quackdown 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 Quackdown rather than just read about it. In short: Quackdown is a South Africa-based website aimed at exposing fraudulent and untested medical treatments. It hosts the "Quackbase" database of untested medical claims and publishes articles on quackery.

Key takeaways

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

Reference excerpt

Quackdown is a South Africa-based website aimed at exposing fraudulent and untested medical treatments. It hosts the "Quackbase" database of untested medical claims and publishes articles on quackery.

Overview Quackdown is a joint project of the Treatment Action Campaign, Community Media Trust and several individuals. It was originally edited by Nathan Geffen, Marcus Low and Catherine Tomlinson, but since December 2012 Catherine Tomlinson is no longer an editor of Quackdown. In October 2012, the South African medicine company Solal Technologies filed a defamation lawsuit against Kevin Charleston due to a Quackdown article he published that denounces the company's magazine Health Intelligence for quackery and pseudoscience. As of 2022, the website appears to be inactive as the Quackbase database was last updated in 2012 and the most recent article on the website dated from 2014. In addition, their Twitter account, @quackbase, has not been active since 2012.

Worked examples

Example 1 — a first encounter with Quackdown

Start with the simplest possible case. Write down what Quackdown 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 Quackdown 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 Quackdown 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 Quackdown

In research: Quackdown 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 Quackdown 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: Quackdown is common in secondary-school and first-year university syllabi. It links to neighbouring topics Internet properties established in 2011, Medical websites, Scientific skepticism mass media, so understanding it makes those chapters shorter.
In everyday life: Look for Quackdown 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.

Frequently asked questions

What is Quackdown in simple terms?

Why does Quackdown matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Quackdown?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
