I think people must have a different idea than I about what "true" means.
If the Law of Attraction is true, it must have a noticeable, repeatable, statistically significant effect on the way reality works. If it does have this effect, why wouldn't scientific methods be able to discover it? This is exactly what scientific methods DO—they let us learn whether some noticeable, repeatable, statistically significant effect is happening.
How could the Law of Attraction be true if it doesn't have a noticeable, repeatable, statistically significant effect?
