Suppоse yоu wаnt tо design аn experiment testing whether people аctually perceive the moon as being bigger when it is close to the horizon. You build a simulated version of a moon and a horizon in the lab and recruit some volunteers to report how big they think the simulated moon is (in centimeters) when it is close to the simulated horizon and when it is far away. You repeat this a few times for each person and compute the average estimates for the two conditions. To keep the participants interested, you play quiet classical music (Moonlight Sonata) when the moon is far away from the horizon and loud, upbeat music (Dancing in the Moonlight) when the moon is close to the horizon. Which of the following best describes a well-reasoned limitation to this study?
