Allen Dick, referring to Dee Lusby, said: "Although I believe in the need for controlled experiments, I can see her point. What they are doing works and she doesn't feel a need to do things anybody's way but her own. She is sharing the methods and stock and anyone who cares to can do controlled experiments on their own time." As well as getting on and simply doing it, Dee Lusby appears to be claiming a degree of cause and effect. She is not simply "doing things her own way", but attempting to explain the results as well... At that point, I lean back to the need for the scientific method. And if Dee Lusby didn't understand what Karen Oland was trying to say to her and the list, try looking up Occum's razor... Nick Wallingford [log in to unmask]
