The above is a very ambiguous statement. It also is grammatically incorrect. These two points led me to question the alleged source: April 23, 2019 ,
Johns Hopkins University School of Medicine
It turns out the author is a well-respected researcher, Roland R. Griffiths, on the effects of psychedelics. However, he is also a strong god believer.
The article has some statistics regarding the number of participants but nothing regarding the number of atheists.
The vague opening paragraph apparently accomplished what the author wanted: give the impression that even atheists can come to see god whether naturally or with the usage of psychedelics (WHICH I AM NOT ADVOCATING).
Note the clever wording of the paragraph...
"a survey of thousands of people"
"more than two-thirds of atheists"
Well, if the survey was "of thousands of people who reported having experienced personal encounters with God", how many were atheists? Correctly, none would have been atheists. What is 2/3s of none?
However, this intentionally vague and misleading wording accomplishes what the author intended. It gives people like Antanu a reason to start a forum thread with the header:
God experience can change atheists
If atanu had bothered to read the article he would have seen the article mentions atheists only twice. Never does tha article say how many of the thousands of people who reported having experienced personal encounters with God were atheists. That is either shoddy research or intentionally misleading rhetoric.
But atanu isn't alone. The article was reprinted by many groups who believe that even hardened atheists are desperately looking for god.
For the record, we aren't.
