I would say that science is science, and sound science is ensuring that you use the totality of the evidence before you.
The difference between the two is that you can have one scientist saying one thing and another scientist saying another thing. How do you balance that? From our perspective, we use the concept that it's not only the use of science, but also integrating that within thinking of the weight of evidence. The weight of evidence is really important. You have to take a look at the collective amount of relevant information, and you have to make a balanced determination collectively on all of that information, so that you can come up with a decision.
For me, the difference would be that sound science ensures the application of the weight of evidence in your decision-making matrix.
