This is closer to reality than you may think: that arbitrary threshold is a statistical line - a P value of 0.05 - which is used in science to determine whether results are statistically significant. Despite its widespread use, there is growing concern that the concept of statistical significance based on the 0.05 (or any other) threshold is actually causing many problems: overconfidence in single studies, false impressions of results being in conflict and a tarnished literature.
