The overarching point of this article will be to convey that behavioural psychology may be out-of-fashion, but still has many things to contribute to modern psychology.
All science is ultimately born of philosophy (see Pepper, 1942) and therefore there is no reason why this science should play second fiddle to any other. However, in the rat race to make strides in the science of behaviour, principles of science are often discarded in favour of convenience. The dominant school of thought in psychology at present is cognitivism. This school adopts a predominantly top-down approach to psychology. This involves simplifying phenomena into their perceived component parts, in order to study them. This phenomenon may constitute a set back for the way research is conducted and human behavior ultimately conceptualized. Allow me to illustrate why this is a problem.
