Do you eat the crust?
Do you eat the crust of your pizza?
The edge with no sauce. Food, or handle?
A preference, not a test. There is no right answer.
A habit people do not think of as a position
Unlike the sandwich arguments, almost nobody holds this one as a view. It is a habit, performed several times a year without being examined, and people are often mildly surprised to learn that anyone does it differently. That makes it a better measure of behaviour than the questions people enjoy arguing about, where the answer given is partly a statement about which side you want to be on.
The published reference is a YouGov survey of 1,000 US adults fielded over three days in April 2023, on pizza specifically rather than as part of the broader food questions elsewhere on this site. Respondents who did not commit are left out of the shape used here. It is two years older than most of the other references, which matters more for a habit than for an opinion.

Published figures are kept separate from this site’s own responses and weighted lightly against them, so answers measured here overtake the literature rather than being anchored by it.
