What concept in Holland's model describes the degree of relatedness within personality types?

The concept of consistency in Holland's model refers to the degree of relatedness among the different personality types identified within the model. Holland proposed that certain personality types are more aligned with each other based on their characteristics and vocational interests, meaning that individuals whose personalities are 'consistent' tend to fit together well in a professional environment. For example, if someone is categorized as an "Artistic" type, they are likely to find greater satisfaction and success in careers that also appeal to the creative or aesthetic orientation, as opposed to those aligned with very different types, like "Realistic" or "Conventional."

Consistency highlights how closely related personality types can influence career choices and job satisfaction, proposing that individuals whose personal and professional identities align with compatible types are likely to experience better career outcomes. This understanding can help career counselors guide individuals in making informed decisions that align with their intrinsic preferences and natural inclinations. The other concepts, while relevant to various aspects of career development, do not specifically address the degree of relatedness among the personality types as directly as consistency does.
