Respondents were asked to place themselves on a scale from one to seven, "where 1 means you feel abortions should be illegal and 7 means you feel there should be no restrictions on abortion." Among ambivalent respondents randomly assigned to hear this 7-point question first, the mean score was 4.9. But among those randomly assigned to hear the partial-birth question first, the mean legality score was only 4.5, a statistically significant difference.
