"Why I am no longer a skeptic"

I remember that selective reporting was one of the risks, and that indirect comparisons and heterogeneity were part of the downgrading. 

Thanks. I think it's fair enough to point out the lack of pre-registration as a problem, at least in the past. But regarding the other two, I wonder how much those really bear on the strength of the evidence for the existence of a psi effect, as opposed to the accuracy of the measured effect size. I'm not even sure we should be assuming that psi can be characterised by a simple effect size in that way.
