Alright, sorry. My bad. Wishful thinking is a good way to solve problems or get what you want. Thanks, you two!
According to Bandura, one of the most cited people in all of Psychology, and his many many experiments (and thousands of replications): YES wishful thinking has a positive influence on people.
Not only that but as I pointed out earlier in the thread we know that prayer helps people (20+ studies say so), but if it's wishful thinking you want to talk about 20,000+ studies say so.
The power of positive thinking is the best established finding in all of psychology.
