ICE List

ICE List 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 ICE List rather than just read about it. In short: ICE List is a website established in June 2025 by Dominick Skinner, an immigration activist from Ireland living in the Netherlands, which compiles a database and wiki publishing names of ICE agents, and attaching them to incidents where possible. Despite claims from the Department of Homeland Security, the website has never published addresses, phone numbers or email addresses.

Key takeaways

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

Reference excerpt

ICE List is a website established in June 2025 by Dominick Skinner, an immigration activist from Ireland living in the Netherlands, which compiles a database and wiki publishing names of ICE agents, and attaching them to incidents where possible. Despite claims from the Department of Homeland Security, the website has never published addresses, phone numbers or email addresses. As of January 14, 2026 the site had published the names of 4,500 people alleged to be involved with ICE. Much of the information on the site is gathered from public databases (such as LinkedIn) that ICE employees themselves have posted. Several hours after the release of the Department of Homeland Security employee data leak, ICE List was taken down by a direct denial of service attack. The attack was speculated to have originated from Russia, however, the site's owner stated that the attack's source was impossible to determine due to the use of proxy servers and described an attack of that length as "sophisticated." In January 2026, Meta-owned social media sites Facebook, Instagram, and Threads began censoring posts containing links to ICE List. A Meta spokesperson stated that the site was blocked for containing personally identifiable information. In February 2026, RÚV reported that a website about ICE-members were under investigation as personally identifiable information was being made public, and Iceland's minister of infrastructure, Eyjólfur Ármannsson, announcing intent of making legal amendments with regards to Iceland's conduct with the national top-level domain .is.

Worked examples

Example 1 — a first encounter with ICE List

Start with the simplest possible case. Write down what ICE List 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 ICE List 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 ICE List 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 ICE List

In research: ICE List 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 ICE List 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: ICE List is common in secondary-school and first-year university syllabi. It links to neighbouring topics Immigration-related protests, Immigration-related protests in the United States, Internet databases, so understanding it makes those chapters shorter.
In everyday life: Look for ICE List 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 ICE List in simple terms?

Why does ICE List 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 ICE List?

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.
