How wise is popular wisdom? In Chapter 1, we pondered how many old sayings have other old sayings that contradict them. For example, a common saying is "You can't teach old dogs new tricks." But we also hear "You are never too old to learn."

Now that you have read Chapter 2, design a research study in order to test these sayings. Provide your reasoning in selecting a particular research method, subjects, and other key details.

What will be an ideal response?
