A passion to make the world a better place is a fine reason to study social psychology. Sometimes, however, researchers let their ideals or their political beliefs cloud their judgment, such as in how they interpret their research findings. Social psychology can only be a science if it puts the pursuit of truth above all other goals. When researchers focus on a topic that is politically charged, such as race relations or whether divorce is bad for children, it is important to be extra careful in making sure that all views (perhaps especially disagreeable ones, or ones that go against established prejudices) are considered and that the conclusions from research are truly warranted.
