20 posts held, back to 27 December 2021 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 1 pageof Telegram’s post history, 20 posts per page.
Nothing published in the last 30 days. ERR and ER are rolling 30-day measures, so there is nothing to compute — we hold 20 posts for this entry, the most recent from 28 June 2022. An engagement rate over an empty window would be a number about nothing.
63 reactions across 16 posts, in 4 distinct kinds. The most used accounts for 57.1% of them.
| Reaction | Count | Share | Share, drawn |

No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.
Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.
Coverage. Reactions were read on 16 of the 20 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 63reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 20 most recent posts we hold, published 27 December 2021 to 28 June 2022, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

What Science Tells Us About Improving Brain Function and Protecting Against Cognitive Decline If you are taking the N-Back Challenge, it’s presumably because you are eager to raise your IQ and stave off age-related cognitive decline. Yet, cognitive training is just one way of achieving this goal. We recommend that you supplement your dual n-back practice with other interventions that scientists have linked to cognit…

Smarter Students: Using Dual N-Back Training in the Classroom In the past, it may have been enough for educators to convey domain-specific knowledge to their students. But as a teacher or professor in the 21st century, you have an even more powerful opportunity: that of teaching your students how to think, learn, and problem-solve in general. Indeed, between the two, the latter might be the more important educationa…

Why (And How) You Should Keep Practicing After You’ve Completed 20 Sessions of Dual N-Back In accordance with most scientific studies, the N-Back Challenge requires you to complete a total of 20 n-back sessions over the course of 20 days. As you approach the end of your Challenge, you might be wondering what happens afterwards. One of the reasons Susanne Jaeggi and Martin Buschkuehl caused such a stir when publishi…

Understanding the Advanced Settings in the N-Back Challenge The N-Back Challenge was designed to mirror the format of the scientific studies as closely as practical. Yet many students wish to customize certain parameters of the game. To that end, we’ve included a handful of “advanced settings” that you can find within the Settings view. Let’s get a closer look: - Turning on Instant Button Feedback. Each tap of the …

Fight Age-Related Cognitive Decline by Playing Dual N-Back Among cognitive scientists, it is widely known that intelligence — or “general cognitive ability”, declines as we age. Some recent studies have gone further and explored cognitive decline as a predictor variable, rather than a consequence, of health outcomes. The results of these studies are surprising but consistent: Higher cognitive ability is clearly asso…

The Science Behind Dual N-Back Training Intelligence had long been believed to be impervious to training. At some point, however, scientific evidence started accumulating that intelligence may be linked to working memory and can be raised through cognitive training. In our future posts, we will explore several of these studies. For now, let’s focus on the one that was the most surprising. In May 2008, Susanne Jaegg…

A Smarter Workforce: Using Dual N-Back for Corporate Training In today’s knowledge economy, companies invest rising amounts in corporate training to give their workforces a competitive edge. In the United States alone, these investments add up to close to $100 billion per year! Much of the investment flows into expensive in-person events to build domain-specific skills. Yet, there is an exciting opportunity for comp…

Coffees and Pizzas: Why We Ask For a Contribution When You Delay an N-Back Session Upon taking the N-Back Challenge, you commit to playing a session of dual n-back every day for 20 days. Whenever you delay a session, we ask you to support us with a cup of coffee. Being accustomed to free apps, you might be wondering why. We are a small independent company that deliberately eschews institutional funding to protect t…

After completing a few sessions of dual n-back in your quest to raise your IQ, you might, quite naturally, start looking for signs that the training is actually working. How can you tell? Students of dual n-back frequently do report noticeable changes that can plausibly be linked to the scientifically established cogn…

Showing the 12 most recent of 20 posts we hold for @nbackchallenge. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
A live page changes as we take new readings, so a citation should name the measurement it is based on, not just the URL. The line below cites the subscriber count as measured 23 August 2026 — this entry's latest reading, not the date you are reading this.
