Nevertheless, science alone, which usually claims that it is value-free and unbiased, cannot tell us what to do with that information. Therefore in making policy decisions we must individually and collectively apply the divine principles and other pertinent values. Science can gather knowledge but cannot act without a decision-making process that is and must be guided by philosophical values of one kind or another. Yet the knowledge we can acquire about how and why people behave the way they do as individuals and in groups and organizations is certainly going to enlighten our decision-making in evaluating the probable consequences of our actions. Since social science works with people, it must be especially sensitive to ethical concerns.
Natural science is used to manipulating objects in experiments.
Any experiment which attempts to find out if one thing is better than another is likely to be unfair to half of the subjects. Experiments have often been performed where information is concealed from the subjects, and in some cases outright lies have been told to people. I seriously question this practice, because it seems to me that lying obscures the revelation of truth. First of all, it is difficult to know to what degree the subjects believe the experimenters. Generally, in experiments involving humans it is best if they are voluntary and fully informed of the nature and results of the experiment.
