This has always been the case. The standard for scientific proof in the natural sciences is often quite high, and the legal standard for tort claims is usually "preponderance of evidence", which you could think of as a P-value of 0.50. The lowest P-value acceptable in most scientific fields is 0.10, more common you would use 0.05, and particle physicists would use 0.0000003 (for announcing the discovery of a new particle).
