Undergraduate Students Show Average Intelligence. Why?

The longstanding perception that undergraduate students are intellectually superior to the general population has been upended by recent research executed by Bob Uttl, Victoria Violo, and Lacey Gibson. Once thought to possess significantly higher IQs and Intelligence, new evidence reveals that today’s university students are, on average, no more intelligent than the broader population.

As higher education has become more accessible, the average IQ of undergraduates has steadily declined, challenging the myth of their exceptional brilliance. This shift has profound implications for universities, employers, and students themselves, as the reality of average intelligence reshapes expectations and standards across the board.

Besides discussing these results we will also handle how intelligence in undergraduate students is assessed to show that it is a multifaceted endeavor that encompasses various methodologies and considerations.

The results of intelligence assessments can be influenced by numerous factors and present several challenges in obtaining accurate measurements. Ultimately, these assessments have important implications for the field of education, shaping how institutions approach teaching and learning.

On Average, Undergraduate Students’ Intelligence Is Merely Average

The research included a meta-analysis of 106 samples of undergraduate students, representing a total of 9,902 students. These students were tested using various versions of the Wechsler Adult Intelligence Scale (WAIS) between 1939 and 2022. The samples were drawn from both the United States and Canada, with 102 samples from the U.S. and 4 samples from Canada. The study aimed to provide a comprehensive overview of the average IQ of undergraduate students over time and across different institutions.

Contrary to long-held beliefs that undergraduate students possess significantly higher intelligence than the general population, recent research reveals a different reality. Historically, it was assumed that university students had an average IQ of 115 to 130, suggesting a level of brilliance well above the population norm of 100. However, this notion is based on outdated data from the 1940s and 1950s when university education was accessible only to a select few. Today, with the dramatic increase in educational attainment, the average IQ of undergraduate students has declined to approximately 102, placing them squarely within the average range of the general population.

Data Used

The comprehensive meta-analysis of IQ scores from 1939 to 2022 in the USA and Canada shows a steady decline in the intelligence of university students, roughly 0.2 IQ points per year. This decline reflects broader societal changes, where higher education has become more widespread. As a result, university students now represent a broader cross-section of society, rather than an elite intellectual group.

Moreover, the intelligence of students varies significantly across different institutions and fields of study. For example, students in fields such as mathematics and physical sciences tend to score higher on standardized tests like the SAT and GRE, compared to those in education or social services. Additionally, more selective universities, which admit students with higher SAT scores, generally have students with higher IQs.

These findings have significant implications. Universities must adjust their curricula and standards to reflect the current student population’s average abilities. Employers can no longer assume that a university degree is a marker of superior intelligence. Students, too, should recalibrate their expectations, recognizing that university admission does not necessarily place them in an intellectual elite.

The belief in the exceptional intelligence of undergraduate students is a myth rooted in a bygone era. The reality today is that these students are, on average, just that—average.

Key Results

Here are the key results from the research on undergraduate students’ intelligence to check one by one:

  1. Average IQ Decline: The study found that the average IQ of undergraduate students has steadily declined over the past 80 years, with a current average of approximately 102 IQ points, which is just slightly above the general population average of 100 IQ points. This represents a decline of about 0.2 IQ points per year.
  2. IQ Variation Across Institutions: There is substantial variation in IQ scores across different universities and fields of study. Students in more selective institutions and fields such as mathematics and physical sciences tend to have higher average IQs compared to those in less selective institutions and fields like education or social services.
  3. Impact of Educational Expansion: The expansion of higher education over the last several decades has contributed to the decline in average IQ among university students. As more individuals pursue university education, the overall average IQ of the student population has decreased, reflecting a broader cross-section of the general population rather than an elite group.
  4. SAT and GRE Correlation: The study also found a moderate correlation between the mean IQ of students and their SAT or GRE scores, suggesting that standardized test scores are somewhat predictive of student intelligence, although this correlation varies significantly across institutions.
  5. Implications for Universities and Employers: The findings suggest that universities may need to adjust their curricula and academic standards, as the student body is no longer composed of predominantly above-average individuals. Employers can no longer assume that a university degree signifies a higher level of intelligence compared to non-degree holders.
  6. Challenging the Myth: The research challenges the longstanding belief that undergraduate students are inherently more intelligent than the general population. This myth, based on outdated data from the 1940s and 1950s, no longer holds true in the context of modern higher education.

The Debate Continues

The democratisation of education has led to a debat where it is even said that too many people go to university as this video shows which was filmed at the Royal Geographical Society on 30th January 2007.

Understanding the Concept of Average Intelligence

Average intelligence, often represented by an Intelligence Quotient (IQ) score of around 100, signifies the median level of cognitive ability within a given population. Intelligence is typically measured through standardized tests that assess various cognitive skills such as logical reasoning, problem-solving, and verbal comprehension. These tests are designed to provide a quantifiable measure that can be used to compare cognitive abilities across individuals.

However, intelligence is a broad and complex construct that cannot be fully encapsulated by a single score. It encompasses multiple dimensions, including emotional intelligence, creative thinking, and practical problem-solving abilities. The traditional IQ test primarily measures analytical and logical reasoning skills, which are just one aspect of a person’s overall cognitive profile. Therefore, while average intelligence provides a useful benchmark, it is not a definitive measure of an individual’s full intellectual capabilities.

Furthermore, the concept of average intelligence is dynamic and can vary across different cultural and educational contexts. What is considered average in one society may differ significantly in another due to variations in educational opportunities, socio-economic factors, and cultural values. As such, it is crucial to approach the assessment of average intelligence with an understanding of these contextual differences.

Importance of Assessing Undergraduate Intelligence

Assessing the intelligence of undergraduate students holds significant importance for both educational institutions and the students themselves. For institutions, understanding the cognitive abilities of their student population can inform curriculum development, teaching strategies, and resource allocation. By identifying areas where students may need additional support or enrichment, universities can tailor their programs to better meet the needs of their students.

For students, intelligence assessments can provide valuable insights into their strengths and areas for improvement. This self-awareness can guide their academic and career choices, helping them to pursue paths that align with their cognitive abilities and interests. Additionally, understanding their own cognitive profile can empower students to develop effective study strategies and seek out resources that enhance their learning experience.

Moreover, intelligence assessments can play a role in identifying gifted and talented students who may benefit from advanced programs or specialized instruction. Conversely, they can also help in recognizing students who may be at risk of academic underachievement due to cognitive challenges. Early identification and intervention can be crucial in providing these students with the support they need to succeed academically.

Methods Used to Evaluate Student Intelligence

Several methods are employed to evaluate the intelligence of undergraduate students, each with its own strengths and limitations. Standardized tests, such as the Wechsler Adult Intelligence Scale (WAIS) and the Stanford-Binet Intelligence Scales, are commonly used tools that measure various cognitive abilities. These tests provide a composite score that is often used as an indicator of general intelligence.

In addition to standardized tests, other assessments such as the SAT and ACT are frequently used in the context of college admissions. While these tests are not designed specifically to measure intelligence, they do assess critical thinking, problem-solving, and verbal and mathematical reasoning skills, which are components of cognitive ability. The results of these tests can provide valuable information about a student’s readiness for college-level work.

Another method for assessing intelligence involves the use of psychological evaluations conducted by trained professionals. These evaluations often include a combination of standardized tests, interviews, and behavioral observations to provide a comprehensive assessment of an individual’s cognitive abilities. This holistic approach can offer a more nuanced understanding of a student’s intellectual strengths and weaknesses.

Factors Influencing Assessment Results

Several factors can influence the results of intelligence assessments, making it important to consider these variables when interpreting test scores. One significant factor is the individual’s educational background and learning experiences. Students who have had access to high-quality education and enrichment opportunities may perform better on intelligence tests due to their exposure to a stimulating learning environment.

Socio-economic status is another critical factor that can impact intelligence assessment results. Students from higher socio-economic backgrounds often have access to more educational resources, extracurricular activities, and supportive learning environments, which can positively influence their cognitive development. Conversely, students from lower socio-economic backgrounds may face challenges such as limited access to educational materials and support, which can affect their test performance.

Cultural and linguistic differences can also play a role in intelligence assessment outcomes. Standardized tests are typically designed based on the cultural norms and language of the test developers, which may not fully capture the cognitive abilities of individuals from diverse backgrounds. Test-takers who are not fluent in the test’s language or who come from different cultural contexts may be at a disadvantage, leading to potential biases in the assessment results.

Challenges in Measuring Accurately

Measuring average intelligence accurately presents several challenges that researchers and educators must navigate. One primary challenge is the inherent complexity of intelligence as a construct. Intelligence encompasses a wide range of cognitive abilities, and no single test can fully capture all its dimensions. As a result, assessments may provide an incomplete or skewed picture of an individual’s cognitive abilities.

Another challenge lies in the potential biases present in standardized tests. These tests are often developed based on the norms and values of specific cultural and socio-economic groups, which can lead to biased results when administered to individuals from different backgrounds. Efforts to create more culturally and linguistically inclusive assessments are ongoing, but achieving true equity in intelligence testing remains a significant hurdle.

Additionally, the pressure and anxiety associated with taking intelligence tests can affect performance. Test anxiety can lead to lower scores that do not accurately reflect a student’s true cognitive abilities. This is particularly relevant in high-stakes testing environments, where the results can have significant implications for a student’s academic and career opportunities. Addressing these psychological factors is essential to obtaining more accurate and fair assessments.

Implications of These Assessment in Education

The implications of intelligence assessment in education are far-reaching and multifaceted. For educational institutions, the results of intelligence assessments can inform decisions related to curriculum design, teaching methods, and resource allocation. By understanding the cognitive profiles of their students, institutions can create more effective and tailored educational programs that enhance learning outcomes.

For students, intelligence assessments can provide valuable feedback that helps them make informed decisions about their academic and career paths. Recognizing their cognitive strengths and areas for improvement can guide their choices and enable them to pursue fields where they are likely to excel. Additionally, understanding their cognitive profile can help students develop personalized study strategies that enhance their academic performance.

On a broader scale, intelligence assessments can contribute to educational equity by identifying students who may need additional support or enrichment. Early identification of cognitive challenges or giftedness can lead to targeted interventions that help all students reach their full potential. However, it is crucial to approach intelligence assessments with an awareness of their limitations and potential biases to ensure that they are used ethically and effectively in the educational context.
