If two people rate the intensity of a taste as "7" on a 1-to-7 scale, can we conclude that they both had an equally intense experience? Why or why not?
What will be an ideal response?
No, we cannot. Each rates the intensity of the experience in comparison to other tastes that he or she has experienced. Someone who always has weak tastes can rate something as 7 in comparison to the other tastes. In fact, some people have three times as many taste buds as others and more intense taste experiences.
