It would be interesting to get your scientific take on this item. But it doesn't suggest that it is more important than prayer. At least I don't think it does. For me praying in tongues works two ways - I either pray in English first and then carry on praying in tongues. And then often this leads into singing in tongues. Or sometimes the tongues first which then seems to lead me into understand when I pray in English things which I may not have thought of before.
Ok, well first off I am dealing with a press article and not a study directly. As a scientist, I should not make a comment without reading the research first. More on that shortly.
But there is already a problem in that the title is misleading: its talking about speaking in tongues but the article itself says praying or speaking in tongues. This is a red flag to scientists with integrity.
Second thing is there is no reference given to the study in this post. Perhaps its only a partial quote of a longer article, but if you don't reference it... A scientist won't even bother with it.
I did dig deeper and found a study that delt with such, though I am not sure its the same article or one that simply deals with the same topic.
The world of science is harsh. If you publish something it must be refereed (scrutinized) before being accepted. The journal I looked at seemed to be legit, but may not be accepted by mainstream psychological people.
As a person, I will give Dr. Peterson the benefit of the doubt, but the scientists of the world won't! He is a MD, but they won't care. Thwy will judge him on his methods.
By the way, this Doctor has some skeletons in gia closet. I can overlook them, and science should too... But despite their mask, scientists are human too. They are just hypocrites about it, for the most part.
Even so, I did find a study and briefly read it. It would take me 12 hours or more to do a critical analysis on it. I would have to look at the testing methods first. It appears they mentioned hormone levels.
Well, the research question woul be if this data is different to merely relaxing in your easy chair with a beer, or having sex, or listening to classical music, or praying to Allah, or.... You get my point.
As I sit here, I got a kitty on my lap and its comforting! So... Is speaking in tongues any different from the activities I mentioned? If the data is the same, a scientist will conclude that praying or speaking in tongues is no more effective than good sex or petting a kitty!
Now, that is the scientist in me... I'm just relating the method and reasoning.
