The median is almost always around 7, for almost anything.
An anecdote on a related note...
There was once a long-term online survey about patterns of usage of a particular sort of product (specifics intentionally obscured to protect the guilty). One screen asks something like “Which of these have you used in the past year”, and it shows 4 products of different brands in random order and “None of the above”, and respondents can select multiple brands. Different respondents answer every week, but the results are pretty consistent from one week to the next. Most respondents select one brand.
One week, they took away one of the brands. If it were tracking real usage, you’d expect all of the responses for that brand to have shifted over to “None of the above”. Instead, all of a sudden people had used the other 3 brands about 4⁄3 as often as the previous week. It was exactly the result one would expect if practically everyone were answering randomly. That pattern kept up for a few weeks. Then the question was changed back, and the usage of all 4 brands went back to ‘normal’.
Some of the effect could be accounted for by a substitution principle; instead of asking oneself for each option whether one’s used it in the last year, it’s easier to ask which of them one recalls using most recently (or just which of them seems most salient to memory), check that, and move on. If people do actually switch between products often enough, this would create that dynamic.
