The Pestov Test: How Sharp Is Your Logic

Sure that you think logically? Let us check. The Pestov Test on Telegram was devised by analyst Ilya Pestov, and it is built to catch the habit of answering fast without reading carefully. 🧠

The test has 25 questions. They pack in confusing constructions: negations, and-or links, and conditions where it is easy to mix a correct statement with a wrong one.

What exactly is being tested

The test is not about erudition or math. It is about telling a valid logical statement from an invalid one. That is what an analyst, a lawyer, a programmer and anyone who reads contracts needs.

School knowledge is enough, and attention is key. Many people fail not from ignorance but from haste. ⏱

The bot's commands

• /start. Begin the test.
• /answers. View the answers.
• /poll. Take part in a poll.
• /statistics. Poll results.
• /rating. The overall ranking.
• /info. A short reference.

Open the answers after you finish. Peeking earlier would spoil the test.

Why negations throw people off

A sentence like it is wrong that not all students failed to pass takes three readings and a fourth to understand. The brain is used to simple claims and stumbles on a double negative.

To cope, take the sentence apart. Remove the negation, check the meaning, put it back. You will make noticeably fewer errors. 🔍

And versus or

In daily speech, tea or coffee means one of them. In logic, or often allows both at once. This difference catches many people, and the test builds questions on it.

A conjunction (and) requires both conditions to hold. A disjunction (or) works if at least one is true. Keep that in mind and half the confusion disappears.

How to take it and what to do with the score

1. Pick a quiet time. The test does not tolerate distractions.
2. Read every word. Especially not, all and some.
3. Do not guess. If unsure, break the condition into parts.
4. Check the answers. Study your mistakes along with the score.

The ranking is interesting as a comparison with others, but it is not a measure of intelligence. A short 25 question test measures one specific skill, attention to wording, not overall brainpower.

The best value is in reviewing mistakes. If you keep falling for negations, practice exactly those. 🎯

Where this kind of logic pays off

Attention to wording matters wherever a text has consequences: contracts, briefs, promotion rules and manuals. A phrase like everyone except those who did not make it in time can mean something quite different from what it seems.

Practice also helps in conversations: it is easier to notice when someone swaps some for all. 💬

A couple of evenings with such exercises is enough to sharpen your eye.

A test for the office and for friends

Ask colleagues or friends to take the test and compare answers. Arguments over which option is correct are usually the most fun part: you will see how differently people read the same words.
