How do you quantify ability in different systems?

Ability link from Wikipedia I found a book on Amazon Human Abilities: Their Nature and Measurement Paperback – May 7 2015 $75.

Anyone who has been born, and suffered through the ability to live, is a winner in my book.

There are many and they’re all invented or at least focused on particular measures. They can fool people into subscribing to invented value systems.

Your question is extremely broad – questions so broad remind me of ink blot tests, which mainly provide a comment of what they prompt people to say.
