A Critical Thinker's Guide to Testing Stories and Claims

A Critical Thinker's Guide to Testing Stories and Claims

Some stories survive because they are true, and some just because they are good, and telling the difference takes more than gut feeling. These methods differ on what counts as solid ground: some weigh the reliability of sources, others lean on hard data and statistical measures, and others read physical or historical traces. You'll be able to pick the right way to test a claim before you believe it or pass it on.

Evidence and expert calls for transparency show that vaccine safety has been oversimplified, and parents deserve honest information and freedom to make informed vaccination choices. The real path forward requires open investigation and respect for individual decisions rather than dismissing concerns.

Studying Lasting Love: Evidence, Methods, and Limits

Studying Lasting Love: Evidence, Methods, and Limits

Studying love scientifically forces awkward choices about what counts as evidence.
