Working with a group, write a big Why? on a sheet of paper or computer screen, and then generate a list of why questions. Don’t be too critical of the initial list:

Why
— do people laugh?
— do swans mate for life?
— do college students binge drink?
— do teenagers drive fast?
— do babies cry?
— do politicians take risks on social media?
Generate as lengthy a list as you can in fifteen minutes. Then decide which of the questions might make plausible starting points for intriguing causal arguments.
