You are welcome - it is good to share such important testimonies as far as possible. I have learned as an engineer to eliminate assumptions, since they are 'the mother of all fuckups' ;)
Unfortunately, 'science' has been directed in a different direction in many cases - such that assumptions are an accepted part of the process. It's ok to have assumptions when those involved fully appreciate and understand them, but unfortunately, once a study is published it will be used by all manner of people with agendas to attempt to prove their case and it is usually only those 'below' them in society in terms of education and awareness who become the victims.

I don't agree that we will always find what we are looking for in science, since real science results in actual absolute understandings - the problem is that 'real science' is quite uncommon in the sense that most of the 'science' we encounter is biased, yes - and funded deliberately to be so. It is often possible to find studies that confirm your position and also that reject your position, but that implies the presence of error - or possibly an infinite continuum of possibility that supports BOTH positions for reasons that are not being fully appreciated.
