With a d20 as well. It was designed by a gamer for the Metro East Gamers site, but they have stopped using it.
OK. Most of what I saw were newspaper columns, which are possibly more anecdotal by design.
Let's look at a couple of specific examples. Two students both taking the SATs, both neurotypical. One of them was raised middle-class in a safe neighborhood, well-fed, and with well-funded schools. The other was raised in poverty, in an unsafe neighborhood, facing food scarcity, and poorly funded schools. However, they are now taking the same test and will be graded the same way. Is this equality to you (I know some people who would say it is, including Sowell, AFAICT)? For me, equity would be that we help the second child live in a better neighborhood, eat better, and fund their schools. Then, we can see them better fulfill their potential on the test.
Second example. Two students taking the SATs raised in similar environments, one of them has severe dyslexia. The student with dyslexia has a person who helps them read the questions and answers on the test, but does not help them decide the correct answer. That's what I think of as equity. Would that be your word?
For me, equity is removing the disadvantages (or compensating for them) that come with being raised poor, being black, etc. Since I think humans are basically the same, I see equity as achieving equality of outcomes not because we force the end result, but because we even out the starting positions. There will still be janitors and doctors, and doctors will still earn more.
