A scientist would generally be considered a success by their success at experimenting. Their experiments would not depend on their beliefs but on the physical nature of the universe and their knowledge thereof.
It could be argued that philopshyphilosophy is a kind of science as there are things that can be quantified. For example, if somebody had killed another person ever or not. But, if anything, it is a meta-physical science that does not intadictinterdict physical sciences.
A mystical person may interdict an experiment for their own beliefs but a thought alone can not stop a physical process such as an experiment. More often than not the various benefits of science is generally seen to outweigh the cost, so the scientist/experiment won't meet many physical restrictions and would be allowed to succeed.
