That isn't really a fair comparison though. I might like boiled peanuts, you might prefer Surströmming, we're all good. Your preference doesn't diminish my enjoyment of peanuts. This misses something about religions though. Each religion makes claims that are incomparable with other religions. People who prefer peanuts to Surströmming don't generally believe that the Surströmming fanciers are wrong.
In a sense, they do. They might rationally claim that you are not constituted in the manner required to enjoy Surströmming. (What the heck is that?)
If you want to reduce the claims of religion in general, and Scientology in particular to being like liking Surströmming. You enjoy it, I don't, but it doesn't matter because none of us actually believe we are making objective claims about the world, then fine, but I don't think that is actually what most of the religious people who come here actually believe.
If it's an honest claim about the world, as we agreed, then they can do nothing else. It is no different than any other claim I make about the world, including the claim that scientific evidence is a reliable path to truth. I believe that just as strongly as someone else may believe that chanting and meditation is a better path.
If the fact that I could demonstrate it were enough, there would be no chanting going on.
Why then come to a sceptical forum?
Probably not much different than why anyone comes here -- good discussions. I find it difficult to make nuanced arguments elsewhere. I dig the peeps that hang out here, they have good minds. Unlike other forums that take from me, this one gives back. I should mention I cannot prove that scientifically.
Generally if your beliefs are well founded Science will agree with them. If Science persistently disagrees with your beliefs you might want to take a step back and have a think about whether you are absolutely sure. I mean, if you thought the experiment would validate your beliefs, but it didn't, you are clearly wrong about your beliefs in some way, or the experiment would have worked... no?
I agree, however I think we often assume that others see the terrain the same way we do. For example, I once was involved in a discussion about trimming a round, wooden half-shell to meet specifications. This was at a plant that manufactured shaped plywood. There were perhaps four involved in the discussion of how to get what we wanted, among them the shift supervisor.
I argued based on mathematics and was surprised to find the concept of pi and circumference foreign to my workmates. With math in hand, the problem was straightforward and the answer plain. They didn't buy into it and went with an iterative cut-a-little then measure, then repeat plan instead.
The lesson for me was that a tool loses its power when others don't trust it -- even when it gives the correct answer. And that's what's going on with our insistence on scientific experimentation. To the Scientologist's eyes, it isn't a trustworthy tool. A better tool, from their perspective is self discovery and reliance on authority (other people said it works and LRH has books).
If this is how they generally run their lives, how can I challenge it based on claiming I have a better tool? The problem is that their process yields the results they expect -- or the results can be "explained to fit."
It also gives good results when you realize how few people actually join up. I have seen estimates of only one in a hundred going past any initial training. With that in mind, I'd say the experiential, try it and see method is doing a fairly good job.
