- The 1st site, http://www.alzheimersupport.com/, is a commercial
site that sells nutritional supplements that are claimed to benefit people
who suffer from Alheimer's Disease or similar ailments.
The quality of the information at this site is questionable,
since their discussion of the usefulness of commercial
products for treating Alzheimer's Disease
may be biased by the fact that the site has a
commercial interest in the products advertised.
- The 2nd site, http://www.alzheimers.org/, indicates that it is
"a service of the National Institute on Aging (NIA). The NIA is one
of the National Institutes of Health under the U.S. Department of Health
and Human Services."
For a start, this site is sponsored by a prestigious government
institute, National Institute on Aging (NIA),
so it is backed by the authority of the NIA.
In that sense it may be considered to be fairly authoritative.
(That is, of course, not the same thing as being correct. But it is the
measure that we are asking about.)
The discussion of the usefulness of commercial
products for treating Alzheimer's Disease is less likely to be
at this site than at the 1st site, since the 2nd site has no obvious
commercial interests, and is in fact affiliated with a prestigious
governmental organization, which lessens (but does not eliminate) the
likelihood of bias.
So, the quality of information at the 2nd site is less questionable
than at the 1st site.
CONCLUSION: The 2nd site is more likely than the 1st to
to provide high-quality and authoritative information on
Alzheimer's Disease and its treatment than the 1st site
(no matter how well-meaning the latter may seem).
