Social justice promotes fairness and equity across many aspects of society and is critical to human rights, economic growth, social stability, and many more. Yet, various evidence reveals significant disparities in social justice issues within the education systems across countries, including the United States1. These disparities permeate the entire knowledge chain, impacting education access2, process3, and outcomes4. Addressing these issues is of utmost urgency, particularly in relation to fostering diversity in STEM (Science, Technology, Engineering, and Mathematics) education participation and success. In the United States, studies have consistently shown disparities based on race, ethnicity, socioeconomic status, and gender1,5–7 within the education system. Students from marginalized communities often face barriers to accessing quality education, including limited resources, inadequate infrastructure, and a lack of qualified teachers8. Similar issues can also be observed in other countries' education systems9,10. Around the globe, students from disadvantaged backgrounds encounter obstacles that hinder their educational progress11,12. These obstacles may include limited access to educational resources, societal biases and prejudices, and systemic inequities13.
However, social justice was often, like in many aforementioned studies, viewed in terms of social privileges related to race, gender, wealth, age, and other common demographic characteristics14. Some non-traditional aspects of social justice, such as alphabetical discrimination, have received limited attention, especially in education and the labor market14–17. Alphabetical discrimination is a prevalent practice where individuals are arranged based on the alphabetical order of the initial letter in their names, typically their last name, in various social contexts such as school rosters, waiting lines, or co-authored paper presentations. Consequently, individuals may face a form of "discrimination" as they are consistently positioned either at the beginning or end of the name sequence due to their last names. For instance, individuals with last names starting with 'A' or 'B' might feel added pressure when they are consistently the first participants in a game if the order of participation is determined by the initial letter of their last name, or vice versa. In the academic sphere, it has been proposed that the alphabetical order of the last name initial can significantly impact one's academic success, particularly in top-tier economics departments where authorship often follows alphabetical ordering. However, this practice is not as prevalent in some other academic fields where authorship is typically based on the order of contribution18.
Alphabetical discrimination can even give rise to social justice concerns at an early stage in one's life, such as participation in the labor market and subsequent outcomes. An experiment conducted by Carlson and Conard19 involving undergraduate students explored the influence of last name order on the timing of item acquisition. They found that individuals with earlier last name initials tend to acquire new items more rapidly. Thomas Zych, a write-in candidate in the 2004 US presidential election, shared his experience of being disadvantaged due to his placement at the end of the last name alphabetical order, which impacted his classroom opportunities and social interactions with classmates and teachers during childhood. Such early experiences of alphabetical discrimination could have long-lasting effects on an individual’s life, particularly if they influence the development of one's psychological beliefs about their academic and career capabilities and, therefore, one’s field of study and career choice.
Research in the realm of alphabetical discrimination is rather limited, and there is a scarcity of studies investigating its potential connection with children’s engagement in education. To address this gap, our study aims to explore the broad hypothesis that the order of one’s last name may influence one's later educational choices in college majors. We hypothesize that the alphabetical ordering of last names may influence students' psychological development, including aspects of their personality, such as their receptiveness to new ideas. If students possess last names situated towards the latter part of the alphabet, they could experience reduced prominence within both classroom and school engagements. This diminished visibility may subsequently deter their enthusiasm for engaging in academic pursuits that necessitate increased interpersonal communication and collaborative teamwork. Instead, they may find themselves more drawn to endeavors that rely on individual effort. Such experiences could potentially contribute to the development of a less open personality during their formative years. We postulate that these variations in personality may ultimately manifest in the students' selection of college majors. Our resulting hypotheses are as follows:
Hypothesis I
When students choose their college majors, those with early last name initials are more likely to select liberal arts majors over the conventional STEM disciplines.
Hypothesis II
Students scoring higher on openness in their personality traits are more inclined to opt for liberal arts majors.
The underlying connection between Hypotheses I and II lies in the notion that students’ personality traits could influence their decisions regarding their choice of college majors. If the order of last name initials indeed contributes to variations in personality development, it would, in turn, impact students' selections of majors during their college years. To rigorously assess our hypotheses and establish causal links to the greatest extent feasible, we took advantage of two unique datasets collected in vastly distinct cultural and institutional contexts. We examined college student registrar data compiled from two national research universities, one located in the US and the other in China.
Please note that alphabetical ordering is widely utilized in the US. In contrast, in China, urban areas employ both alphabetical and stroke count-based ordering systems, while most rural areas do not follow any specific ordering method. Therefore, it is unlikely to observe that the last name order would have much impact on Chinese students' personality development and major choices. However, Chinese students are subject to a different social injustice that goes beyond their control, such as the rural–urban residential registration system. Students from rural residential households are often considered “inferiorly” than those from urban residential households, which may lead to a difference in their personality development. Therefore, we further refine Hypotheses I as the following:
Hypothesis I (a)
Students in the US with an earlier last name initial are more likely to choose a liberal arts major compared to the traditional STEM majors.
Hypothesis I (b)
Students in China with an earlier last name initial show no pattern in major choices between liberal arts majors and STEM majors.
If both hypotheses are validated, they offer preliminary support for establishing a causal connection between the alphabetical order of last names and students’ major choices, mediated by differences in personality. The China scenario would demonstrate two important points: (1) the significance of personality in shaping college major preferences, and (2) a counterfactual case where last name ordering has no impact on personality development, but urban-rural residency does. Hence, students' major choices differ by urban-rural residence but not by last name order.
This study offers significant implications and insights for policy development in the field of education, particularly concerning children's psychological and behavioral development mechanisms. The findings of this research can contribute to the design of effective and equitable policies within US classrooms and in a global context. By gaining insight into how last names influence students' academic choices in college, policymakers and educators can implement appropriate measures to guarantee equal participation opportunities in STEM fields for all student demographics, thereby fostering a diverse and dynamic STEM workforce. Additionally, policymakers and educators can formulate guidelines that tackle potential discrimination and actively promote fairness and inclusivity within educational systems. Additionally, these insights are valuable for behavior economists, as they provide a new perspective for modeling the decision-making processes, especially in development economics, where education and workforce participation play crucial roles in strategies addressing poverty. Furthermore, this research contributes to theories in science and technology studies by examining an understudied factor: name discrimination and its influence on individuals' decisions to pursue STEM fields and careers. It highlights the significance of considering various factors, including names, when analyzing academic and career involvement patterns.
