The Importance of Meta-Analysis in Economics

I bring it up because there are so many areas now in social psychology where a result that someone might have questioned in the past and was told, are you kidding? The evidence is overwhelming. A meta-analysis is not going to fix the literature that is flawed. I mean, if every single study is flawed, you will get a flawed result from the meta-analysis. But just by looking at that universe of studies, you can really get a better understanding of what is going on here.
