In which neuroanatomical substructure does the religious principle reside again?
I have no idea which neural structure is responsible for religion, but that it is genetically determined can be deduced from the fact that all cultures, no matter how isolated, have some sort of deity and spiritual belief (and with rather similar structures). Richard Dawkins and Matthew Alper have both presented the hypothesis, although Dawkins myopically attributes religion to a misfiring neural mechanism, rather than its correct functioning.
Sometimes false hope can be a powerful healing agent; placebo effects are well known for such. Yeur brain is a powerful tool, and being able to trick it to take full advantage of that power instead of letting it stay dormant is rather useful.
However... it can also be quite bad... 'peace of mind' can come at a high cost... and if yeu get caught doing that, sometimes yeu can get in a nasty lawsuit for selling fake stuff.
There's also been quite a few cases of people DYING due to false hope... where they were absolutely certain that something would cure them! Aaaaand... it was a total hoax. So they passed over things that actually would've cured them to instead go with something that only offered hope but not actual help.
There's also situations where someone will do something truly stupid due to false hope, which can come back and bite them shortly after... I mean, how many people get drawn in on scams?
By the way... if yeu send me $5000, I'll return yeu a million sometime later on. I'm actually a nigerian prince. Srsly.
It doesn't matter if they're right. If they can't proove they're right, then they're wrong. No matter how right they may be.
