Not all skills are typically developed to the same degree, so the perceived resistance may differ in different areas. One person I know has a weakness in mathematical thinking, which in their case means that they score only 1.5σ in math tests, but 3σ to 4σ in other tests. They recognize their weakness very distinctively. Whenever they try to solve a mathematical problem it feels like ‘‘wading through molasses’’ to them. Interestingly, they score very high in logical thinking when it is unrelated to mathematics.
