How science really works, in 11 minutes

Why does health research seem to contradict itself every day? This video explains the science behind those confusing headlines and how the scientific method helps us separate good psychology studies from bad ones. One day, alcohol is bad for you; the next, a glass a day is healthy. Dietary cholesterol is a villain, then it's harmless. Does vitamin C actually prevent colds, or is it just a sugar pill? These flip-flopping headlines are confusing and can make you lose trust in science. But the problem often isn't with science itself—it's with how we interpret weaker studies. This video breaks down the common pitfalls in research. You'll learn: 🔹 The crucial difference between correlation and causation. 🔹 How "confounders" and the placebo effect can ruin a study. 🔹 The step-by-step process for designing an experiment that gives reliable answers. 🔹 What makes a Randomized Controlled Trial (RCT) the gold standard of scientific evidence. By the end, you'll understand why studies seem to conflict and have the tools to be a smarter consumer of scientific news. 🧠 EXPLORE 1 MILLION+ CORRELATIONS As mentioned in the video, correlation doesn't prove causation... but it's fascinating to explore!
