David Binder Research, Summary Memo on Transportation

This report was prepared by David Binder Research. It’s a great example of how our discussion of credibility can be extended to talk aboutĀ evidence — how to get it, how to use it, and how to evaluate it.

As you examine this report, think aboutĀ evidence. How was it gathered, and how is it presented?
