The Theoretical Foundation of the “BOSS” Model

BOSS Personality Profiles were created as a result of analysis of your childhood experiences and through the lens of the following four (4) stereotypical birth order styles:

The BOSS Personality Model is different from other “biologically based” Birth Order Models in that it is based on stereotypical sibling experiences and not only on the chronological order of birth.

Any specific individual may have a profile that does not reflect a “pure” stereotypical birth order. In fact, individuals may have had a mixture of different stereotypical sibling experiences that have formed personality, behavior, and preferences as an adult.

For example, if a middle child had an older sibling who was much older or absent during childhood, they may have taken on responsibilities typical of a first-born child, such as caring for younger siblings.

The BOSS Model survey is a set of questions designed to elicit participants’ stereotypical sibling experiences. Based on these, it predicts adult leadership styles, preferences, and behaviors.

Core Assumptions of the BOSS Model

Assumption #1

Spaced Repetition of the Same Behaviors Builds Habitual Behavior

Habitual behavior is formed through the spaced repetition of the same behaviors. Starting with Pavlov’s research, it’s understood that children who repetitively experience certain situations are more likely to respond similarly as adults.

Example: We easily recall multiplication tables as adults because we practiced them repeatedly in school.

A study published in the European Journal of Social Psychology (2009) by Phillippa Lally and colleagues at University College London involved 96 people forming habits (e.g., eating fruit with lunch, running daily). Participants were asked how automatic their behavior felt. Over time, most reached a habit plateau at around 66 days.

This shows early repetition boosts automaticity, which levels off as a habit solidifies.

Assumption #2

Birth Order Stereotypical Sibling Experiences Affect Adult Leadership Styles

Growing up in a certain birth order usually leads to repeated sibling dynamics. The BOSS model assumes these repeated experiences create adult behaviors and attitudes.

Example: A first-born often takes on responsibility for younger siblings. If repeated, this leads to a natural adult tendency to take initiative and responsibility in group settings.

Assumption #3

Every Individual is Unique and Complex

No model can fully define a person. The BOSS model simply aims to provide insight — a framework to explore your own patterns and preferences, not a box to contain them.
