In https://skeptics.stackexchange.com/questions/14995/if-homeopathy-does-not-work-why-are-there-so-many-shops-selling-the-products , someone asked an interesting question about homeopathy, but not one that's on-topic for this Stack Exchange:
I gradually got conscious of the fact that there is a huge number of homeopathy shops in London. It is very easy to check, at least using wiki that there exist no scientific evidence that homeopathy works at all. At the same time apparently quite a few people do use it. I wonder if there was some research that explains this phenomena -- why people believe that this can work?
Also I am curious to know if people involved in homeopathy industry really believe in the efficiency of what they are doing?
After explaining why it was off-topic, I was asked for sites which may be more suitable for this question. Unfortunately, I don't know of any good sites, as I'm not involved in the skepticism movement. Does anyone have some good suggestions?
