It's not clear inasmuch generalized knowledge based on research of behavior is actually useful in specific situations. And some of that "research" is idiotic beyond comparison. I once saw a test they did to find out whether cats prefer commercial cat food or mice. The setting of the test was a veterinarian's examination room, a cat was placed on the examination table, and the veterinarian placed before the cat a bowl of commercial cat food and a dead mouse, and then waited to see what the cat would choose. It chose neither and jumped off the table. Only someone with absolutely no regard for animals could "design" such an "experiment."
