I have no problem believing that your level of intelligence reflects your level of experience.
I have no problem believing that this level of intelligence reflects your level of experience. No reason can be given for denying it. As you were born and raised in a large city or rural area without any schooling, the skills you learned are already well-established and there was no need to learn them in the first place. When you grew up as a child, the skills you learned were passed down through family lineages. So it is highly unlikely it would matter that your level of intelligence is higher than mine if we were to compare IQ tests.
What else would they be talking about? It's not like people of similar levels of intelligence had access to the same education or the same language skills.
When you are young you are very much in tune with life around you. The world around you is your home, most likely as a teenager in the city and even for many years thereafter. You don't just leave your home, or even your neighborhood, but stay for life. You are always aware of others and their people, whether you share a home or no. You are familiar with every aspect of life, all of the different social contexts, their ways of acting and interacting, their customs, and so on. There is something magical to this. One does not see the world in a totally natural way, it happens automatically, which gives rise to a sort of universal language. There is something magical about that.
If you compare IQ tests with your level of education that has nothing to do with it. There are numerous studies on the relationship of IQ and IQ tests to general education ability, college entrance exams, and such. There are several others on which correlation can be drawn with IQ. People who are highly intelligent seem to perform at more or even at less than average levels at IQ tests. In one study which involved a wide variety of groups there was a significant correlation between a person's high IQ test scores and his/her perceived competence in a variety of areas. If you take this correlation and apply it to a wide variety of subjects it will show that you tend to get higher levels of competency for higher levels of IQ. You can learn to read, write, and think clearly, and if you test and analyze these things effectively and often you will be good at them. There is a natural tendency to produce high levels of skills in one area and to produce low ones in others. So you can't just choose one
