The experiment design has an interesting flaw: the values that the users assigned to the questions were indicated by marking a position on a line, not by writing out a number.
In other words, they might have simply measured where people who don't give a shit about answering questions in a stupid survey make arbitrary line markings on a sheet of paper when having to struggle a bit to hold up a heavy clipboard, versus when easily holding a light one.
