There have been a number of studies - academic, scientific ones - on the 'power of prayer'.
I can think of at least two meta-studies off of the top of my head. Both of which happen to be medical, as that's where I was at the time. Both agreed that there is no evidence that 'prayer' has any effect above and beyond a standard placebo effect.
Sure. Single studies may show any number of things. Such is the reality of normal variance. If 100 people were to take four bean plants. Two in a red pot, Two in a green pot. I promise you a few would return and claim that red pots make the beans grow taller.
In reality, overall, the results would be neutral.
Heck. If a scientist ever did claim that a meta-analysis (a group analysis of related studies) resulted in prayer being positive. We wouldn't hear the end of it, I'd see it brought up all the time. As such, the actual studies which show no results aren't thrown around, because anyone who know their worth knows that they are useless to convince the people who need convincing.
If you started dancing and sacrificing to some rain god for rain. I'm pretty sure, if you did it consistently, you would come to feel that you were having some effect. It's called observer bias. We remember the positive outcomes (i.e: my prayer came true). But not the negative ones, and thus get a skewed, biased, view. A proper analysis would show that the positive outcomes are no more than expected random variation.
As for your link to the water, it quotes:
"After the lengthy review of Emoto’s research methods and results, I have come to believe that Dr. Emoto is offering pseudoscience to the masses in the guise of defensible research."
These poeple really. Really piss me off. I don't care if people get ripped off by claims not based on scienece. Their own damned fault.
It's not based on science. Does not refer to any science, does not stem from science and has no grounding in scientifi enquiry.
Dr Emoto's theory is no more a scientific theory than me saying:
"I theorise that there are green fairies at the bottom of my garden. They always hide form humans, so we can't see them. But they're the ones that send me happy dreams at night"
Using scientific jargon, or going thorugh supposed scientifc motions to justify ripping people off. Really winds me up.
Then again, I'm not the one being ripped off. If you want to spend $35 per bottle of 'emotional water'. More fool you.
If you want to pray over soya beans. Or anything else for that matter. Go ahead. It's not my time being wasted. But just don't claim that a concerted, scientific study would proove effectiveness. It won't
They haven't.
I really am half tempted to perform a study on soya bean growth and prrove that a repeated study would yield no statistically significant result. But I know that my effort would mean nothing anyway.
Whoever you vote for.
The government wins.
