This is a crappy psychology study where none of the researchers is a psychologist. PNAS is a big name in medical science (?), but an unimportant journal in psychology.
There's no serious psychology journal going to publish this kind of stuff. Why? The first problem is measurement. What is the reliability of using positive/negative words to determine positive/negative emotional state? 70%? 80%?
The effect size of this study is 0.001, which would be way way way smaller than the measurement error. LOL. What a laughable "study".
