 Why was the second round of tests more important to the test subjects?
The point of the second test was not to find the difference between cheap and expensive beers but instead to compare a variety of top-of-the-line beers. One aspect of the reward was that they would presumably enjoy the actual testing more--fewer rueful beer descriptions along the lines of "urine" or "get it away!" were expected than in the first round. The other aspect of anticipated reward was the panelists' unspoken but obvious assumption that this time they would "do better" on the test. Here is what happened and what it meant: 1. Procedure. This was similar in most ways to the experimental approach of Round 1. The A-to-J labeling scheme was the same for all testers.
