Triangle Taste Tests: Are the Subjects Who Respond Correctly Lucky or Good?
研究了三角味觉测试中两次都答对的受试者是否真的比答对0或1次的人辨别能力更强，发现关键信息来自答对一次与答对零次的人数比例，而非两次全对的人数。
When a triangle taste test, i.e., “Which of these three stimuli is different from the other two?”, is given twice to each subject, a natural question to ask is: “Are the subjects who got both tests correct really better discriminators than the other subjects who got 0 or 1 correct?” Surprisingly enough, the answer to this question has nothing to do with the number of subjects who got both correct, i.e., the twos. Rather, it is the ratio of the ones to the zeroes that supplies the necessary information. This information on the subject's abilities to discriminate can be used to develop a weighted voting procedure for subsequent preference tests.
