How the Interview Was Constructed: Brad and John were interviewed separately. We agreed that it would be best if they would reply without hearing the other guy's answer. Then we would list their answers next to each other to compare.
This simple method worked out extremely well...
I liked the fact that both Brad and John could take their time and really think about the question before responding. I was going to do an audio interview, but decided against it.
This e-mail format allowed me to time to come up with better followup questions. With an audio, I tend to feel rushed.
The result is a report that lets you compare thought out replies between two scientists who have spent a large amount of time in the supplement industry. Enjoy!
