Brazilians attempting to validate neuropsychological reports of giftedness or high Intelligence Quotient (IQ) in Portugal have encountered a rigid technical barrier: documentary rejection. European institutions and Portuguese clinics do not automatically accept tests performed in Brazil, requiring patients to undergo a complete retest in the country. The reason is not persecution, but rather the mathematical and statistical precision demanded by neuroscience and local legislation.
Neuroscientist and researcher Dr. Fabiano de Abreu Agrela, director of the Heráclito Research and Analysis Center (CPAH) and member of several international high IQ societies (such as Mensa International and Triple Nine Society), explains that intelligence is not an absolute number, but a comparative metric.
“IQ tests, such as the WAIS, are based on population norms. An individual’s cognitive architecture and performance are measured in comparison to the statistical curve of their country of origin. Portuguese legislation mandates the use of European standards because processing speed, logical retention, and vocabulary vary according to the environment and educational system. Applying a South American standard in Europe generates a mathematical bias and an inaccurate diagnosis,” explains Abreu.
However, the specialist warns that there is a second factor exacerbating this blockage: the trivialization of diagnosis in the current market. The lack of psychometric rigor in the application of some tests has generated an inflation of scores, where exaggerated results often do not correspond to the patient’s actual executive function. “When a report arrives in Portugal with an extreme score, but the patient does not demonstrate the corresponding structural and neurobiological efficiency, the European system goes on alert and blocks validation for clinical safety reasons,” he points out.
To solve this technical bottleneck, the CPAH has a team of Portuguese professionals specialized in European standards. The goal of the research center is not just to retest, but to map an individual’s cognition through logical data that respects the rigorous standards of European psychology councils.
“Real intelligence is an exact equation of how the brain functions. Retesting in Portugal ensures that the numbers on paper truly reflect the individual’s reasoning ability, filtering out statistical distortions and delivering a cognitive profile with international validity,” concludes the director.
