 What was the difference between the first and second test?
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. 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. The first test was designed to evaluate low-end beers and therefore had to be lager-centric. To include one holdover from the previous test, as a scientific control on our tasters' preferences.
