Exploring Sheldon’s Typology: Understanding Human Behavior through Body Types and Personalities

Introduction

The intricate relationship between body types and personality traits has long fascinated psychologists and researchers. One of the earliest attempts to quantify and categorize this relationship was made by American psychologist William Herbert Sheldon in the 1940s.

His framework classified individuals into three primary categories: endomorphs (characterized by a rounded physique), mesomorphs (muscular and athletic), and ectomorphs (slender and fragile).

By analyzing the strengths and limitations of Sheldon’s theory, this paper aims to contribute to a deeper understanding of how body types may influence personality and beha
