I suppose I don’t know how in person voting works. Are there pamphlets inside the booth? Otherwise how are people supposed to refer to it?

WA has been mail-in voting for years, so I vote at home with the pamphlet on the table and a cup of coffee.

Pamphlets are allowed inside the booth, but you have to bring it. They are sent separately in the mail some weeks before the election. At the voting booth they just give you the ballot. The ballot only has the brief descriptive text.

We have vote-by-mail as well, but the number of people who actually read the pamphlet and make an informed decision (rather than just briefly scan the ballot at the last minute) is small enough to matter.

It seems most people don't even research the ballot before going to the polls. People are surprised by the referendums, so how can they make an informed decision? Many seem to go to the polls with the plan of filling out the super bubble to vote party line without even looking at the candidates on the ballot (Dem or Rep).
