Viewpoint: Yes, the genetic and historical evidence strongly suggest that Thomas Jefferson fathered at least one child with Sally Hemings.
Should statistical sampling be used in the United States Census
Viewpoint: Yes, statistical sampling offers a more accurate method—at much lower cost—for determining population than does physical enumeration.
Has the calculus reform project improved students' understanding of mathematics
Viewpoint: Yes, reform-based calculus provides students with a better grasp of the real-world applications and context of mathematical principles, and it also increases the participation of student populations that have been underserved by traditional teaching methods.
Do humans have an innate capacity for mathematics
Viewpoint: Yes, recent scientific studies suggest that we are born with at least some mathematical ability already "hardwired" into our brains.
Does private strong encryption pose a threat to society
Viewpoint: Yes, while it's true that data encryption protects and furthers important civil liberties, it also poses a threat to public safety.
Does the addition of fluoride to drinking water cause significant harm to humans

Viewpoint: Yes, syphilis originated in the New World and was brought to Europe by Christopher Columbus's crew.
Is the cost of high-energy laboratories justified
Viewpoint: Yes, research in the area of high-energy physics has already led to numerous advances that have provided great public benefit, and the search for the ultimate building blocks of the universe is a fundamental part of human nature and an expression of human civilization.
Historic Dispute : Do neutrinos have mass
Viewpoint: Yes, the Japanese-U.S. research team called the Super-Kamiokande Collaboration announced experiment results in 1998 that proved that neutrinos do indeed have mass.
Do hidden variables exist for quantum systems
Viewpoint: Yes, hidden variables are necessary to explain the contradictions and paradoxes inherent in quantum theory.
Does cold fusion exist
Viewpoint: Yes, the experiments of Martin Fleischmann and Stanley Pons offered legitimate proof that cold fusion exists, and subsequent efforts by other scientists have supported their claim.
Historic Dispute: Is Earth the center of the universe
Viewpoint: Yes, early scientists believed that what appeared to be movement around Earth by the Sun and other entities was, in fact, just that.
