There are a multitude of different theories on intelligence and achievement. While intelligence theory remains a highly contentious issue, there are commonalties among prominent research based and non-research based theories, particularly the adoption of belief over testable theory by researchers. The embracing of speculative theory exemplifies a serious dilemma when combining multiple theories to create an archetypal definition. Conjecture can often take the place of measurable analysis. Shedding light on a single pinnacle theory of intelligence remains conjectural, due to the highly complex and nuanced nature of human development. Furthermore, there are immeasurably different perspectives on the meaning of intelligence, and the implications of intelligence theory in general. However, exhaustive research based theories often produce the greatest impact when tested effectively and placed within the context of investigative evaluation. This paper seeks to examine the various components of intelligence theory in order to develop a more comprehensive approach that identifies how intelligence is a complex combination of many different factors.
