Peter,

Notice the subject line of Paddy's original post.  Most of us were pointing out that his attempt to use statistical analysis was flawed, to say the least. 

In other words, if you are going to head your message/post with the words "statistical analysis," you had better do that analysis properly.  If not, then just state that you seem to have alot of premie friends who are successful/happy. 

That was the point on my end and it appears to be the point of most of the responses (pointing out where Paddy's statistical analysis was errant).  The definition of bias doesn't include "proper review" of a claim.
