The Breakfast Question: Does the "But I Had Breakfast" Answer Reveal Low IQ?

The breakfast question, "How would you feel if you didn't have breakfast this morning?", has no correct answer and no scoring key, and a reply of "But I did have breakfast" does not show low IQ. The claim traces to anonymous 4chan posts of 15 June 2021 about an unnamed prison study, as Know Your Meme records it. We found no researcher or data attached to it. The psychology it borrows, how people treat hypothetical premises, is real.

How would you feel if you didn't have breakfast this morning?

There is no correct answer. "Hungry", "fine" and "But I did have breakfast" are all replies to a question with no scoring key, and none has been shown to measure intelligence.

Online the prompt appears as "this morning", as "yesterday morning" or, in the first post as Know Your Meme records it, as breakfast and lunch "yesterday". Nobody has scored the answers: no scoring key, answer distribution or comparison group has ever been published for it.

What is the breakfast hypothetical?

The breakfast hypothetical is a one-line prompt. A person is asked how they would have felt had they skipped breakfast that morning, and the "trap" is to answer from fact: "But I had breakfast this morning." The claim attached to it is that people who answer this way are failing to engage with a counterfactual premise, and that this separates lower-IQ people from higher-IQ ones. You will see it called the breakfast IQ test, the breakfast test or the breakfast question meme. No scoring key, answer distribution or comparison group has ever been published for it.

Where does the breakfast question actually come from?

According to Know Your Meme, the claim traces to anonymous posts in a 4chan /pol/ thread on 15 June 2021. One user said they had been a graduate student on an IQ research team that tested convicts at San Quentin State Prison. In five posts the user described people with IQs below 90 and below 80 failing tasks that involved hypotheticals, recursion and the passage of time. The first post said those below 90 could not imagine how skipping breakfast and lunch the day before would have affected them, and replied that they had breakfast. No researcher, institution, publication or dataset is attached to the story, and we found none. Screenshots spread on Reddit in 2021 and 2022, and a wave of memes followed in late January 2023.

What does "But I did have breakfast" mean?

It means the person answered from fact, not that they cannot reason. A person who says "But I did have breakfast this morning" is describing their real morning. The question asks about a morning that did not happen, and nothing in it tells the listener to treat that premise as true for the sake of argument. Many people hear it as a question about their actual morning, which is an ordinary reading of an ambiguous sentence. Psychologists have studied the underlying habit for almost a century. According to the abstract of Dias, Roazzi and Harris (Psychological Science, 2005), a research tradition begun by Luria in the 1930s found that unschooled adults reason poorly from unfamiliar premises and fall back on an inappropriate empirical bias. Luria did that fieldwork in Central Asia.

A 2005 study put that conclusion to a direct test. Dias, Roazzi and Harris, in Psychological Science, tested two groups of adults, illiterate and unschooled adults and adults with limited schooling, on problems that contained either a premise with unknown content or a premise contradicting everyday experience. Given a minimal prompt, both groups showed what the authors call the customary empirical bias, answering from what they knew. When they were explicitly asked to think of the premises as pertaining to a distant planet, they reasoned accurately and justified their conclusions in terms of the premises they had been given. The authors' abstract adds that earlier findings showed the same for young children with little or no schooling.

In that light, "But I had breakfast" is better read as an answer to a question with no signal to imagine than as a measurement of intelligence. A prompt that began "Imagine a morning when you skipped breakfast" would be a different test, and the studies suggest it would give different answers from the same people. That is our reading of the research, not a result the meme's defenders or critics have tested on this exact question.

So does getting the breakfast question wrong mean anything?

Not reliably. A reply to the breakfast question cannot be scored on any scale: it has no scoring key, no answer distribution and no comparison group. The one study we read that tested the framing (Dias, Roazzi and Harris, 2005) found that a distant-planet frame changed how the same adults reasoned. A single ambiguous riddle cannot separate that effect from ability.

Is the breakfast test a real IQ test?

No. Actual IQ tests do not use gotcha riddles. They use items that are standardized, so every test-taker sees the same wording under the same conditions, timed consistently, and normed against a large reference sample so a raw answer converts to a percentile with a known margin of error. Raven's Progressive Matrices, one of the most widely used nonverbal reasoning tests, is a good example of what that looks like in practice; see our explainer on how Raven's matrices scores work, and our note that high-IQ riddles are not IQ test items. A viral post with no named author has none of those properties.

Why do gotcha "IQ tests" like this keep spreading?

The format is built for social media rather than for measurement. It is short enough to screenshot, it lets whoever shares it feel like the smart one, and it invites an audience to sort friends and strangers into "gets it" and "does not get it" in a single reply. None of that requires the underlying claim to be true, and a claim built around insulting whoever fails it has little incentive to be checked, since checking it only weakens the insult. The same shape shows up in chain messages claiming "only 2 percent can solve this" and in puzzle images claiming a specific reply proves genius; the tell is the same each time, an extraordinary claim about intelligence with no named source, no scoring key and no comparison group behind it.

This is not the only viral IQ tell that falls apart on inspection

The breakfast question sits alongside other confidently shared claims that do not survive a check of their source, including the idea that people who overestimate their own ability must have a specific kind of low intelligence, which turns out to be a more mixed story; see our piece on whether the Dunning-Kruger effect is real. A related meme, the bell curve with a "midwit" in the middle, gets the same treatment in our look at what the midwit meme gets right and wrong.

Other viral claims get the same check. The bat-and-ball question is a real trick question, with measured answer rates. Einstein's riddle and the 98 percent myth is another viral claim that fails on inspection. Whether IQ testing itself holds up is covered in is IQ debunked, and a sibling myth, the idea that we use only 10 percent of our brain, is checked in how much of our brain we use.
