Values therefore relate to the use of facts in order to change our fitness, to move us through the coevolutionary landscape. Science, despite claims to the contrary, is thus not value free. We use facts to produce the equations relating them, and then use these equations to make predictions about the dynamic changes in those facts with time. These predictions are fitness predictions and relate to our interests. The same facts therefore fuse with our value systems in such a way as to generate and modify our projected fitnesses.
Value is a relative fact that varies in significance from zero to infinity.
Given that we do have values in science, then we need to understand just what they are and how they affect our objectivity. We can redefine objectivity here in fitness terms, in that being objective is being able to evaluate fitness in any context without outside bias. Note that we do not use the term 'personal bias' here, since we are formulating a science that should treat equally both external and internal processes. What is outside as an object may be inside for a personal goal, and thus social biases can be subjective when applied to individual objective decisions. Value relativity is context relativity and we can objectively enumerate this if we wish by explicitly defining the contextual limits.
