At a glance
- In a 1977 Stanford experiment, roles were drawn at random, yet contestants and observers rated questioners as more knowledgeable.
- The questioners, who knew how their questions were made, did not rate themselves above the people they quizzed.
- The role alone can create the gap, but real interviewers often do know their field, so subtract the seat's advantage instead of assuming equal knowledge.
In this essay
The interviewer reads the next question off a printed sheet, and the answer you knew this morning slides out of reach. Across the table, they nod as if the right answer were obvious. You walk out with a clear verdict: they know far more than you do, and the gap showed every time you paused.
The same verdict follows you elsewhere. A manager in a review meeting asks about a figure you can’t place. A quiz host reads out a question about a river you have never heard of. Each time, the person asking seems sharper, and you feel a little smaller in your chair.
That feeling rests on something real, because you did miss the answer. What it leaves out is who chose the question. How much of what you saw was the person, and how much was the seat they happened to be sitting in?
Why the asker seems to know everything
The belief has an easy source: it matches what you can see. In any exchange built on questions, one person speaks only about things they already know. The other has to answer in public, on topics they didn’t pick, with no time to look anything up.
From the outside, that looks like a contest of knowledge. The asker never misses, because nobody is asking the asker anything. The answerer misses some, because the questions came from a private store of facts. You see the misses. You don’t see the store.
A pub quiz makes this plain. The host may or may not be cleverer than the teams in the room. What the host certainly has is the answer sheet. Yet by the third round, it is hard not to treat the person at the microphone as the best-informed person in the building.
Job interviews and meetings follow the same shape, with higher stakes. An interviewer may draw questions from their own projects. A manager may ask about a report they read last night and you saw last month. The format hides that choice, and what’s left looks like ability.
A quiz where the roles were drawn by chance
In 1977, the psychologists Ross, Amabile and Steinmetz turned this setup into an experiment, published in the Journal of Personality and Social Psychology. Students at Stanford were assigned at random to be a questioner, a contestant or an observer. Questioners wrote 10 challenging general-knowledge questions from their own knowledge, then put them to the contestants.
Random assignment matters here. It means there was no reason to expect one group to be better informed than the other before the quiz began. Any gap in how they were judged afterward had to come from somewhere other than who they were.
According to summaries of the paper, contestants and observers rated the questioners’ general knowledge as better than the contestants’. The questioners did not rate themselves above the people they had quizzed.
What this shows is limited but clear. Within one short lab session, a role handed out by chance was enough to make one student look better informed than another, both to the person losing and to the people watching. What it can’t show is how real interviewers or managers compare with the people they question, since nobody in that room had earned their seat.
The questioners’ own view is the detail worth keeping. They knew their questions came from their own store of facts, picked to be challenging. The contestants and observers saw only the result. The only people in the room who could see how the questions were made were also the only ones who didn’t find the questioner more impressive.
The limits of one lab quiz
This study is old and easy to stretch too far. Its participants were Stanford undergraduates who knew they were in an experiment, meeting for one short exchange. A pub quiz sits closer to that setting than a hiring panel does, where the stakes and the history between people are different.
There is also a sourcing caveat. The original paper survives as a scanned document, and we could not check its tables directly. The result described above comes from secondary summaries, which is why this piece gives no rating figures or sample size.
The bigger caveat concerns real life. In the lab, the role was random. At work, it usually isn’t. Interviewers and senior colleagues often get to ask the questions because they know the field. The study shows that a role alone can create a gap in how smart someone looks. It does not show that the person across the table knows no more than you.
The original interpretation has been examined from other angles, too. A 1996 paper in the Journal of Social Psychology looked at the quiz effect through social roles, social norms and self-presentation, not only as an error of perception. Its findings are not covered here, so the point stays modest: the 1977 account is not the only explanation on the table.
Subtracting the seat before you compare
Psychologists have a name for the habit underneath all this. Gilbert and Malone, in a 1995 review in Psychological Bulletin, describe the correspondence bias: inferring stable traits from behavior even when the situation could explain it. They name four mechanisms behind it: lack of awareness, unrealistic expectations, inflated categorizations and incomplete corrections.
Their review is general and does not rest on this quiz. Still, two of those mechanisms fit an interview well. You can miss the situation entirely, because the question-writing happened before you walked in. Or you can notice it, tell yourself the asker had an edge, and still not adjust far enough.
So the comparison changes order. Before weighing whether someone is smarter than you, look at what the seat gave them. Did they pick the topics, and did they know the answers before the conversation began? Could you have written 10 questions they would miss?
After that subtraction, some of the gap may remain. An interviewer with years in the field may still know more about it than you do. But whatever remains is a more honest measure, and it describes their knowledge of one area, not your mind as a whole.
Try this today
The next time a question leaves you blank, whether in an interview, a meeting or a quiz, give yourself a short task afterward. Take a sheet of paper and write three questions from your own work or interests that the asker would probably have to guess at. The name of the tool you use every day. The step your team always skips. The odd fact you picked up from a hobby.
You don’t need to ask anyone these questions. The point is to rebuild the half of the picture the format hid. The 1977 study didn’t test this exercise, so treat it as a working habit rather than a proven fix.
Then set the question you missed next to the three you wrote. If the list came easily, part of the gap you felt in that chair belonged to the chair. If it came slowly, that tells you something too: one area worth learning, not a ruling on how smart you are.
In the Stanford quiz, only the questioners knew how their questions had been chosen. Your three lines put that knowledge on your side of the table.
Before deciding someone knows more than you, ask who picked the questions and whether they knew the answers before you sat down.
