Homeopathy – it doesn’t work so why do so many people believe in it?

This is a very nice clear thinking explanation of why smart people believe in nonsensical remedies like homeopathy.      In his book "Why people believe weird things", Shermer cleverly points out that many of our perceptions of how the world works come from childhood experiences and observations and contexts.  Later, rather than truly apply critical thinking to our notions, most of us simply work to rationalize those childhood perceptions using a scientific method tool box.     I'd suggest a good test of a clear thinking person is that they will, over time, collect evidence about their cherished beliefs and will tend to change their mind about a variety of things based on that growing body of emperical evidence.
