Introduction
This study is part of the research line on intelligence and cognition at CPAH, within the framework of the Genetic Intelligence Project (GIP). The investigation aimed to analyze the relationship between high intelligence quotient (IQ) levels, the presence of twice exceptionality (such as ADHD, ASD, and dyslexia), and academic performance history.
The sample consisted of 100 volunteers who are members of high IQ societies, selected from the scientific discussion group Gifted Debate. Participation was restricted to individuals whose admission to these societies required formal proof through supervised, scientifically validated, and internationally recognized IQ tests. This criterion ensures the reliability of the declared IQ, consistent with clinical thresholds for giftedness (IQ >130).
Methodology
Data were collected through a structured questionnaire including questions about IQ range, school performance, presence of neurodivergent conditions, and self-reported cognitive characteristics. The responses were anonymized and statistically processed using comparative categories and relative frequency analysis.
Results and Findings
The statistical analysis revealed the following:
- Individuals without twice exceptionality presented a higher proportion of above-average academic performance.
- Participants with IQ between 130 and 145 showed the best aggregate academic performance.
- Those with IQ above 145 exhibited greater variability, with higher proportions of average or below-average grades.
- The presence of twice exceptionality was associated with a greater incidence of lower academic outcomes, even in individuals with high cognitive potential.
These findings emphasize the role of emotional, adaptive, and contextual factors in the academic performance of gifted individuals. High intelligence alone, while necessary, is not sufficient to ensure academic success, particularly in the presence of conditions requiring specialized educational and psychological support.
Ethical Considerations
This study has a strictly scientific and statistical purpose. All data were collected anonymously, with no direct or indirect personal identification. Data protection procedures are fully compliant with the Brazilian General Data Protection Law (LGPD) and the European Union General Data Protection Regulation (GDPR).
