Absolutely, and a big part of being a good scientist is acknowledging that subjectivity (and well as the degree of uncertainty in all our knowledge). In social science, subjectivity is baked in... there's no way to avoid it, no matter how hard you try.
That's not to say subjectivity means science can't do anything useful in these areas. Most of the problems with subjectivity come from pretending something is objective when it's not.
