The concept of success is one that affects every person in every career and is, therefore, important to research. This research paper addresses the question of whether competency or likability is more important in business and how the two qualities are correlated in the context of success. The paper aims to study whether a sociable personality is enough to succeed in the business sector or if pure competency and excellence in the field is the key to success. Multiple studies are examined that address the correlation between likability and success, such as Belmi and Pfeffer (2018), who discuss reward interdependent environments and explain why likability is less important than competency in such environments. A study by Cohan et al. (2013) looks at the Myers-Briggs Type Indicator of successful project managers and discusses why ISFP is the most successful personality among project managers, determined by both subjective and objective data. The results of these studies show that likability is essential to success in most careers, but that competency will ultimately reign in reward interdependent careers. This research paper concludes with psychological and physical keys that promote success and likability, specifically in the business sector. Van Edwards (2017) shares how liking others is the root of being likable and gives quantitative data on how and why likability can help everyone succeed in business.
