Yes, the optimization goal (the objective function) is a major factor in the function of algorithmic systems. I'm not sure bias is the best word to use here, however.
It is a known challenge to align the designed purpose of an algorithm with actual optimization metrics. For instance, recommendation systems may have the purpose of improving user experience, but if time-on-site metrics are used as the optimization function, there can be unexpected results.
