My last day as Editor of Psych Science. Whew! Best wishes for new Editor Patricia Bauer!
New publication from our research group in @NatureHumBehav showing that meta-analyses substantially overestimate effect sizes and that commonly used methods for bias adjustment do not substantively improve results: https://www.nature.com/articles/s41562-019-0787-z
