For native English speakers, IQ largely correlates with general intellectual ability. People with higher IQs are generally more capable of understanding more complicated topics. It’s not a moral failing to have a low IQ, and there’s no reason to assume it’s genetically heritable or innate and immutable.
The problem is that IQ is very poor at actually identifying “general intellectual ability,” as “general intellectual ability” is not a linear spectrum but a highly complex and multi-faceted phenomena.
