Science says:
"People who are relatively short and those who wish to be taller tend to have more “Dark Triad” traits, according to new research published in Personality and Individual Differences."
"The Dark Triad refers to a set of three related personality traits: psychopathy, narcissism, and Machiavellianism. Psychopathy is characterized by a lack of empathy and remorse, impulsivity, and a disregard for social norms and rules. Narcissism is characterized by an inflated sense of self-importance, entitlement, and a need for admiration. Machiavellianism refers to a tendency to be manipulative, cynical, and lacking in morality."
"shorter people and those who wished to be taller tended to exhibit more psychopathy, narcissism, and Machiavellianism."
"Shorter people, especially those who wish they were taller, are more characterized by traits that are likely to make them show-off, be confrontational, and interested in power,” said Jonason, the author of “Shining Light on the Dark Side of Personality.."
"But why would shorter people tend to have more dark traits? The researchers said that “these relationships may be best understood from an evolutionary framework, suggesting that when people cannot be physically formidable, they may then be psychologically formidable instead."
"When individuals are physically smaller or weaker, they may use psychological tactics to compensate for this. For example, shorter men may demand respect, acquire resources, and impress romantic partners with their personality traits, while shorter women may use deception to appear more desirable or gain protection and resources. These psychological tactics may provide advantages in survival and mating, and may offset physical disadvantages."
