====Conceptual foundations====
There are four primary concepts that ''Popularity Explained'' relies on.

# '''Liking and attraction are not the same.''' The interpersonal feeling of "liking" is not the same as "attraction" and that both are responsible for different human behaviours. The neurological evidence of this comes from the research of [[Kent C. Berridge]] and his [[incentive salience]] model. ''Popularity Explained'' extrapolates the conclusions of this research and applies it to human-human interpersonal interactions.
# '''A hierarchy of interpersonal attraction exists in all social groups.''' ''Popularity Explained'' develops a very broad definition of [[interpersonal attraction]] asserting that it is based on a multitude of different factors but primarily those of: socioeconomic status; interpersonal similarity; physical appearance; and efficacy. It proposes the concept of a "Hierarchy of Attraction" which, in simple terms, is just a stylized bell curve that illustrates how attractive people are relative to each other in terms of a percentile.
# '''Interpersonal attraction (in the broadest sense) results in Input of Energy.''' Input of Energy is the interpersonal actions that an individual takes, consciously and unconsciously, when they experience an interpersonal attraction. Examples of Input of Energy given in the book include: attempts at physical proximity; changes in verbal communications; changes to non-verbal communication; biased interpersonal judgments; cognitive intrusion; and helping behaviour.
# '''Sociometric and perceived popularity are correlated but not equivalent.''' By combining these two concepts, ''Popularity Explained'' defines eight prototypical student types that can be plotted on the single graph.
