The Test
Explanation
The Joke
Scientists develop a test that can perfectly predict whether a child will grow up to be a great scientist. They administer it to millions of children. The test reveals that many potential geniuses are born in poverty, without access to education, and never get the chance to develop their abilities. The scientists are horrified — not by the children's results, but by the realization of how much human potential is being wasted.
The Humor
This is one of SMBC's more serious comics. The "joke" is really a gut-punch: the biggest obstacle to scientific progress isn't the difficulty of the problems, but the systematic waste of human talent through inequality. The setup (a genius-detection test) is sci-fi, but the conclusion is a real and well-documented phenomenon — the majority of potential Einsteins and Newtons throughout history never had access to the education and resources that would have let them contribute.
Context
This comic is frequently shared in discussions about educational inequality and access to STEM education. The economist Raj Chetty has published research on "lost Einsteins" — children from disadvantaged backgrounds who would have become inventors and innovators if given the same opportunities as their wealthier peers.
