Sherwood syndrome

Sherwood syndrome is a physics 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 Sherwood syndrome rather than just read about it. In short: Sherwood syndrome is a police tactical metaphor invented by David Piqué during his tenure as General Commissioner of Territorial Coordination for the Mossos d'Esquadra, the police force of Catalonia. It is not clear what he intended to convey by the term, but it has been wrongly interpreted in Spain as supportive of repressive police tactics.

Key takeaways

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

Reference excerpt

Sherwood syndrome is a police tactical metaphor invented by David Piqué during his tenure as General Commissioner of Territorial Coordination for the Mossos d'Esquadra, the police force of Catalonia. It is not clear what he intended to convey by the term, but it has been wrongly interpreted in Spain as supportive of repressive police tactics. Piqué died in 2016. The name Sherwood syndrome was given by Piqué. It refers to the legend of Robin Hood in which Robin Hood himself decides who deserves to be targeted and robbed and who does not as they pass through Sherwood Forest.

Thesis Piqué's thesis analyzes the squatters' movement in Barcelona during the 1990s and 2000s, more specifically the squatters' movement in the Gràcia neighborhood. It establishes public safety strategies that could be implemented to address this issue, and derives its ideas in particular from the strategies of wartime conflict and classical military theory literature. The thesis criticizes actions to incite protesters. It discourages carrying out arbitrary detentions before an actual protest takes place, cause that would increase the emotional intensity of the protest and would transition it to what the thesis calls "a pitched battle". Then, during the protest itself, police should avoid the "Miyamoto Musashi model", in which police would use excessive force and provocation towards demonstrators with the intention of turning them violent. To that point, the text disapproves that some police forces remain inactive until "the damage done to public property becomes socially unacceptable". The police should charge rapidly and directly against protestors so they do not have the chance to create havoc. The text advocates for interventions that minimize "innocent victims", avoids violently scattering of the protesters and to carry out only necessary arrests. Finally, if protesters cannot be deterred from using violence, the thesis suggests harnessing this to generate negative public opinion toward the protesting group. In the case of squatters in Gràcia, Piqué specifically advocated for following this up with legislation that both criminalizes illegal squatting but promoting at the same time cheap social housing. Meanwhile, the police would arrest those whom who Piqué described as "unbeatable" or "leaders" who would later on be prosecuted according to law.

Reaction When the text was first made public, it raised some concerns because it was misinterpreted to prescribe legally questionable police practices supposedly to be carried out by the Catalan police.

Worked examples

Example 1 — a first encounter with Sherwood syndrome

Start with the simplest possible case. Write down what Sherwood syndrome claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Sherwood syndrome 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 Sherwood syndrome 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 Sherwood syndrome

In research: Sherwood syndrome appears in physics 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 Sherwood syndrome 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: Sherwood syndrome is common in secondary-school and first-year university syllabi. It links to neighbouring topics Law enforcement stubs, Military strategy, Robin Hood, so understanding it makes those chapters shorter.
In everyday life: Look for Sherwood syndrome 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 Sherwood syndrome in simple terms?

Why does Sherwood syndrome matter?

Because it connects several physics 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 Sherwood syndrome?

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.
