It can be IF the person is not being professional and/or carfeul in how they conduct their work. The biggest problem in experiments is accounting for variables, and this is often something that isn't known about until work procedes, and failures happen. This isn't due to bias or subjectivity, but incomplete data.The thing that very few people recognize about science is that the questions asked, and the experiments derived to answer them, are all, themselves, 'subjective' in that they are based entirely on the understanding that we currently hold about the nature of existence.
And bias is the assumvtions we make. In science even a creationist can come to the same conclusions as atheists IF they follow the scientific method. That is the point of the method, to remove bias that may exist in human minds. The statistics are also formulas that remove the personal bias, and leave it up to what the data says.And that is inevitably a subjective, limited, and flawed understanding. So although science tries to help us weed our our biases, it can only do so to a limited degree.
Like creationists. Would you consider atheists to be guilty of subjective bias because they haven't adopted some religious beliefs from society?Science is NOT the antidote to subjective bias that so many (of you) folks these days sadly want to believe.
If not that, then what bias? Or is the bias you are referring to your own bias against science, calling it scientism?
