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.

Power posing became a popular claim about confidence, hormones, and behavior, but later replication efforts sharply narrowed what the evidence can support. This overview explains the original findings, the methodological disputes, and the difference between measurable effects and subjective confidence. Readers will learn where posture-based confidence techniques may be useful, where the science remains weak, and how to apply such tools without overstating their power.

Many popular claims about trauma therapy based on The Body Keeps the Score rely on limited or promotional sources rather than solid scientific evidence. This leads to confusion between compelling body-memory ideas and the actual, often inconclusive, research on trauma treatment effectiveness. Recognizing these gaps helps avoid uncritical acceptance and encourages demand for rigorous data that can truly improve trauma therapy outcomes.
