Given that CSPI and ACSH have been mentioned on several posts in this section, and CSPI clearly takes issue (to some degree, anyhow) with the corporate funding which ACSH receives (or received), it might be interesting to read this recent response by ACSH to CPSI:

This article touches on some of the issues suggested by K in one of his posts in this thread ( corporate funding can bias a researcher, but can also result in important discoveries).
My impression is that CSPI has its own axes to grind and I'm not convinced that they're any less biased than ACSH may be.
