Actually, NCG, detection equipment just permits observations.  Our failures at observation can also fail us in observing the output of detection equipment. 

It's in the analysis, reasoned or not, where the problems are. 

I do stand corrected - human senses come into play in observing testing equipment output.  In my little world, getting those test reports from calibrated standards plays a big role in taking the guess-work out.

The field of data analysis is the where opinions run free.  I have strong opinions - but acknowledge my naive status in this field.  I am hands-on with specifications, levels of detection, and test reports. 

But only a fan - not even an amateur - at sophisticated data analysis.  My opinions are from reading Phil of Sci - papers, not from actual statisical analysis programming and data mining.  I respect those folks, but the analysis is only as good as the models they use for parsing.
