Most biological scientists would have been grounded in the theory of evolution and so on, so there's a general acceptance that human beings are an animal and that our behaviour and everything about us is guided by the same sort of forces that guide other animals, so yes, theoretically that is the case. But there is also an understanding that you have to in some way detach yourself from the natural world in order to study it. So when you're setting up a laboratory experiment you try and avoid introducing bias into it through what you're doing, and so there is that deliberate attempt to remove yourself from the experiment.
