"I once believed the two activities could be logically separated, but I am now convinced human nature decrees no one can to do both."M, With RARE exception to that rule. It seems to fit Orwell's "bad is good and good is bad" writings. The "exception" has become the "rule", and "science" has become subjective to the whims of "present" {any given} day man. This is NOT good. Peace and love, George.
When the result has political or financial ramifications for the investigator, I trust no scientist.
The only way to convince me is to have replications by people with nothing to gain.
