They didn't say it was specific to Haskell, the wording was "than most other languages". My intuition is that they are right. More powerful and fitting tools with a higher learning curve attract different kinds of people than stuff that is tailored for the mainstream. There are also pragmatists who are extremely smart and capable and choose to deepen their expertise in Java (for example). But at _first glance_ it says more about a person if they are proficient in a specialized language than a mainstream one.
