Sure, we trust science all the time, but we also distruct science all the time. It has nothing to do with being selective about it, but judging the sources, as TriShield said.
You of all people should know about bogus studies out there, and the media frenzy that surrounds them.
Let's take the autism link to vaccines...which was redacted recently by the journal that published the original study. And guess what? We will always have groups that still believe it.
Or how about the study that suggests that sunscreen can cause cancer?
Or how about the Lancet study that told us of the massive deaths in Iraq caused by the war...that was also recently redacted?
The list can go on and on...without even getting into global warming.
Scientists used to believe that blood was not circulated, but was created and destroyed after flowing through the body. Turned out to be wrong.
Why should we believe everything right away? Cynicism is the sign of a healthy scientist. People that believe everything they read is not a true scientist.
