I think the
term for what you say is "double standard". Are Wikipedia
editors really that much more prone to Alzheimer's?
It doesn't take Alzheimer's for someone to make a mistake...
Britannica is made by employees that went through an interview process
and had their CVs examined, etc. Wikipedia is made by anyone and
everyone. Britannica may not be any more accurate, but it is more
reliable.
IOW Britannica is more professional at making mistakes. :-)
