Yes, and, I might be misunderstanding your question, but I view that as a good thing. I don't ever want to spend my time in a meeting witnessing people bicker over where to position a dialog button, when you could just run an A/B test and let data guide the decision process.
"Based on the data collected, most users seem to prefer..." is better than, "Based on my training and personal experiences, I think users would prefer..."
It is a lot easier to come to a common agreement on something as objective as statistical significance when compared to personal feelings and opinions.
