UFO Evidence: Science, Secrecy, and Skepticism

UFO Evidence: Science, Secrecy, and Skepticism

The UFO question splits into evidence-first investigation, government secrecy and oversight, the scientific search for alien life, and the cultural and psychological lenses we view it through. These approaches show where skeptics and open-minded researchers diverge on what the evidence actually supports. You can weigh the science against the speculation and reach your own view.

The Replication Crisis: Preregistration, Statistics, Transparency, and Incentives

The Replication Crisis: Preregistration, Statistics, Transparency, and Incentives

The replication crisis has exposed how fragile published findings can be when studies are repeated under closer scrutiny. This overview explains the roles of preregistration, statistical thresholds, trial transparency, and professional incentives in shaping research reliability. Readers will understand the main reform proposals, their tradeoffs, and why the debate over whether science can correct itself remains unresolved.

String Theory and Falsifiability: The Test of Real Science

String Theory and Falsifiability: The Test of Real Science

Science earns its authority by making predictions that could fail, and string theory doesn't. Against its popularity among physicists, the argument here places untestable theory closer to metaphysics than physics, however elegant the math. Taking this view means judging every theory by whether an experiment could ever prove it wrong.
