The results of this survey are interesting, but to interpret them in a vacuum wouldn't really be all that helpful for anyone.

The questions and answers in the survey can lend themselves to various interpretations because of the very nature of the subject and the necessary confounding factors. It's tells us a lot, but maybe not as much about what it intended.

There is really no definitive or concrete... anything about the survey. They would have done better to write a non fiction book of narratives. And that's not to say the information they may have gained through the process is useless, but sometimes presentation can be half of communication.
