The Credibility Gap: Evaluating and Improving Empirical Research in the Social Sciences

Which scientific results can we trust? This question has been brought to the forefront of research in the social sciences in recent years with the movement towards open science practices and preregistration.Systematic replication studies of laboratory experiments in the social sciences have found that only about half of the “statistically significant” results published in top journals can be replicated in the sense that similar results are achieved with new data.This low replicability may be even lower in studies based on observational data as such studies have more degrees of freedom in the analysis of the data leading to larger possibilities to selectively report more publishable findings. In this book, the authors provide a framework for evaluating reproducibility, replicability and generalizability of empirical research in the social sciences.They define different types of reproducibility and replicability and show how they can be measured to evaluate the credibility of published f
