An Abundance of Katherines: The Game Theory of Baby Naming

Core Concepts

Parental preferences for name "uniqueness" can lead to unstable and suboptimal outcomes in the highly competitive arena of baby naming.

Abstract

The paper presents a game-theoretic model for baby naming, where parents aim to choose a name with a desired level of "uniqueness" or popularity. The authors make several "Extremely Reasonable Assumptions" (ERAs), such as assuming parents are myopic and that there is only one gender.
The model considers the dynamics of name frequency and parental preferences, represented by power law distributions. The authors analyze the stability and satisfiability of the resulting name distributions under different parental preference scenarios.
When parents prefer less common names (t' > 0), the name distribution becomes unstable, with popular names quickly becoming unpopular and vice versa. Conversely, when parents prefer more common names (t' < 0), the name distribution becomes stable, with popular names remaining popular over time.
The authors also present simulations using a log-normal distribution of parental preferences, which produce similar insights. Additionally, they include an experiment with the Kat-GPT language model, which suggests gender differences in name popularity.
The paper concludes by discussing potential extensions, such as the creation of new names and considering non-myopic parents, and the implications of their findings.

Stats

The popularity of names follows a power law distribution.
The preference of parents for name "uniqueness" can also be modeled as a power law distribution.
When t' > 0 (parents prefer less common names), the resulting name distribution becomes unstable, with popular names quickly becoming unpopular.
When t' < 0 (parents prefer more common names), the resulting name distribution becomes stable, with popular names remaining popular over time.

Quotes

"Naming a child is akin to choosing an outfit for the Oscars. It must be unique enough to stand out - no one wants to show up to the Oscars in the same dress - but it must also be similar enough to be recognizable as a name."
"If an arrangement is stable, this means that given an existing distribution fi(a) and a parental preference distribution g(µ), every name's frequency will be exactly the same at the next time step i + 1: fi+1(a) = fi(a) ∀a ∈ A."

Deeper Inquiries

How might the model be extended to consider the influence of cultural, social, or demographic factors on parental name preferences?

To extend the model to incorporate cultural, social, or demographic factors influencing parental name preferences, several adjustments can be made. Firstly, the distribution of names could be tailored to reflect specific cultural naming trends. For instance, certain cultures may have preferences for traditional names or names with specific meanings, which could be factored into the model.
Additionally, social influences such as popular media, celebrity trends, or historical events could be integrated into the model. Parents might be more inclined to choose names associated with popular figures or characters, reflecting societal influences on naming choices. Demographic factors such as regional naming variations or linguistic considerations could also be included in the model to capture the diversity of naming practices across different populations.
By incorporating these cultural, social, and demographic factors, the model could provide a more nuanced understanding of parental name preferences and offer insights into how external influences shape naming decisions in diverse contexts.

What are the potential unintended consequences of parents strategically choosing names to achieve a desired level of "uniqueness"?

When parents strategically choose names to achieve a desired level of uniqueness, several unintended consequences may arise. One potential consequence is the creation of naming trends or fads, where certain unique names become popular due to imitation or social influence. This could lead to a loss of individuality as more children end up with similar unique names, diminishing the intended uniqueness of the chosen name.
Furthermore, parents may face challenges in ensuring the practicality and social acceptance of highly unique names. Children with extremely uncommon names may encounter difficulties in pronunciation, spelling, or social integration, potentially leading to feelings of isolation or misunderstanding.
Moreover, the pursuit of uniqueness in naming could inadvertently reinforce societal norms or stereotypes. Parents may unknowingly perpetuate biases or expectations through their choice of unique names, impacting their child's experiences and interactions in various social settings.
Overall, while the intention behind strategically choosing unique names may be well-meaning, parents should consider the potential unintended consequences and societal implications of their naming decisions.

How could the insights from this game-theoretic analysis of baby naming be applied to other domains of human behavior and decision-making?

The insights gained from the game-theoretic analysis of baby naming can be applied to various domains of human behavior and decision-making. One application could be in understanding consumer behavior and market dynamics. Just as parents make decisions based on name uniqueness, consumers may make choices influenced by factors like brand differentiation, product novelty, or social status.
In organizational settings, the principles of strategic decision-making and competition explored in the baby naming model can be applied to strategic management, marketing strategies, and competitive analysis. Understanding how individuals make choices in a competitive environment can inform business strategies and decision-making processes.
Moreover, the concept of parental preferences and decision-making in the baby naming model can be extended to explore family dynamics, interpersonal relationships, and social interactions. By studying how individuals navigate choices and trade-offs in naming their children, researchers can gain insights into broader human decision-making processes and behaviors.
Overall, the game-theoretic analysis of baby naming offers a valuable framework for understanding decision-making under constraints and competition, with implications for a wide range of human behaviors and decision-making contexts.
