How Reporting Statistical Significance Causes p-Value Hacking

Repost: Do Political Scientists Care About Effect Sizes – Replication and Type M Errors

Repost of an article by Christoper Gandrud: Reproducibility has come a long way in political science. Many major journals now require replication materials be made available either on their websites or some service such as the Dataverse Network. This is certainly progress. But what are political scientists actually supposed to do with this new information?
