I'm trying to clarify something. It seems to me that in the category of Stuff That's Wrong with Science, we have these two criticisms:
1. Science keeps changing. First, scientists said X was true. Ten years later, they changed their minds and said Y was true. How can we trust science when it keeps changing?
2. Science is dogmatic. When someone comes along and says, "Hey, Y isn't true after all: Q is true," scientists just point and laugh. If you go against the "religion" of science by proclaiming Q, you'll be ridiculed and denied tenure.
To summarize, science keeps changing and it is resistant to change. Have I got that right? There's something niggling at the back of my brain; something seems wrong, but I can't quite put my finger on what...
