Dear Keith and all,
Thanks for the great summary, Keith! Since one of the respondents
mentioned about Norell's using a test result done at Harvard, I have to
clarify that that test was not authorized by me or any other faculty
members here, and the use of Harvard's name in their promotion flyers
without our consent had drawn Harvard Corporate lawyers' great
attention. The student who did the test was not even aware of Norell's
intention to use his result for such purpose.
Best,
Shaw
