Nobody wants to be weak. Weakness leads to losing.
Weakness leads to resentment.[1]
Intellectual weakness is perhaps the most subtle weakness.
It compounds itself. Physical weakness makes us feel bad.
Intellectual weakness makes us feel smug or leaves us unable to see our weaknesses, intellectual weakness is like a disease with an immune system of its own protecting it from detection.
There are many ways to overcome this problem. The first: learn how to read.
Footnote
[1] The early Christian letter writer Paul explains that weakness can be a form of power, insofar as that weakness is one that the Christian has tried to overcome. In that sense, Paul the apostle can speak of his preference for weakness. But his preference is not an excuse for low-effort, shoddy thinking, or laziness in general. He says elsewhere that he worked harder than all of Jesus’ apostles.
