Which comes first, an hypothesis or the evidence? The answer (often) is: the hypothesis. The evidence may be actually invisible before the hypothesis gathers momentum. For example, this: bq. In an area as difficult as climate science, in which all is complex and befogged, it takes a while to see what one is not prepared to look for A “fascinating historical account(link to the Physics Today site)”:http://www.physicstoday.org/vol-56/iss-8/p30.html from Physics Today of discoveries over two-thirds of a century that suggested climate change could take decades rather than eons. Only in the past decade has the data been widely recognized as evidence rather than illusion.
