Ghana's average IQ is about 90.25. Now, that is not exactly up to the global average, but it's hardly bad by any stretch, considering the country's specific circumstances.
Everything goes into this figure, from the availability of quality education to healthcare to economic prospects.
The bright spot is that Ghana has made a conscious effort to improve in these areas.
Ghana has shown some improvement in education and health in recent times, and there is an expectation that this percentage may improve with concerted efforts.
Nutrition and Early Childhood Development: Bad diets are a serious issue, especially among children. When children lack a proper diet early in life, their brains and bodies fail to develop adequately. They can have learning setbacks and lower IQs when they grow up.
Poverty and Economic Struggles: Poverty-stricken children have more problems, including heightened stress levels and lower access to food and learning. When a child's unmet basic needs, attention in school, or learning the abilities that increase a higher IQ becomes far harder, malnutrition, less access to proper schooling, and greater health issues usually result from poverty and are detrimental to cognitive functions.
Limited Access to Education: Some regions in Ghana are better educated than others. Urban schools like Accra are better equipped, have qualified teachers, and have textbooks. In rural areas, there are overcrowded classrooms, a lack of teachers, and substandard facilities.
Ghana's average IQ of 90.25 is quite close to that of most other nations in sub-Saharan Africa. Here's a brief comparison with some of its neighbors:
Nigeria's average IQ is approximately 91.35
South Africa's average IQ is 94.11
Kenya's average IQ is approximately 91.22
Cote d'Ivoire average IQ is 88.42
Togo’s mean IQ is 89.94
While Ghana's IQ is slightly lower, remember that IQ scores are not fixed. They can be increased as a country enhances things like education, healthcare, and nutrition.
With the proper efforts, Ghana's IQ could rise over time as the positive changes in the country manifest.
