Mind Merit

About

Mind Merit is an adaptive critical-thinking practice supplement for students ages 10 and up. Built on research in distributed practice and immediate feedback, 10-minute daily sessions teach kids to separate claims from evidence and spot 25 classic logical fallacies. These skills matter more than ever when AI can make any answer sound convincing and social media is full of conclusions without solid evidence. I'm Rachel Sheffield. I've taught logic and critical thinking to college students for over 20 years and watched incoming students slowly get worse at evaluating arguments. Very few schools teach it directly, so I built Mind Merit for my own three kids. They loved it, and frankly I think it's amazing, so I opened it to other families. In addition to daily practice spotting flaws in short arguments, every Monday kids get a new true story about a reasoning flaw that happened in real life and had real consequences. For example, the military nearly armored its WWII bombers in exactly the wrong places because it only studied the planes that made it home (a biased sample, also known as survivorship bias). In another, a famous founder answered hard questions about her company's blood tests with a speech about people who change the world (red herring). Kids see that these flaws aren't textbook exercises. They shape real decisions. Parents also get a dashboard showing exactly which flaws their child is stuck on. There are no ads, and it works alongside any curriculum. It's a natural fit as the logic piece of a classical education. Arizona ESA families can pay through ClassWallet Direct Pay.
