Is social psychology scientific in nature?

The term science refers to a general set of methods-techniques used to gather systematic information about the world phenomena.the social psychologists do use the precise methodical and systematic means of investigation to understand phenomena.they do not rely on abstract, untested theories.instead they rely on testing, retesting and testing again all the assertions and hypothesis before accepting them as accurate.so the basic demand of science as observation, experimentation, test and retest in formulating hypothesis and theories is fulfilled in social psychology though its topic of study are different from the physical or biological sciences.
