When the performances of individuals, or preferences for products, are judged in sequence by subjective criteria (think music audition or dance competition), does position in the sequence affect the opinion of the judges? An experiment to look for these order effects (Mantonakis et al. 2009) gave 33 volunteers four glasses of wine in sequence, one at a time. Participants were asked to say which of the four was the superior wine. Unknown to the participants, all four glasses were poured from the same bottle. Fifteen participants preferred the first glass, five preferred the second glass, two preferred the third glass, and 11 preferred the last glass. Is there evidence from these data that position in the sequence affected the preference of the volunteers?
