Political science should not stop young researchers from replicating

In a blog post by Jesse Singal at the New York Magazine, one of the students who tried to replicate LaCour‘s findings on gay marriage said that young researchers are often actively discouraged from replicating work.

The criticism David Broockman (and his co-authors) faced was:

  1. young replicators become known as troublemakers
  2. young replicators should do original work instead

Here’s the paragraph:

Most important, in Broockman’s opinion, his experience highlights a failure on the part of political science to nurture and assist young researchers who have suspicions about other scientists’ data, but who can’t, or can’t yet, prove any sort of malfeasance. In fact, throughout the entire process, until the very last moment when multiple “smoking guns” finally appeared, Broockman was consistently told by friends and advisers to keep quiet about his concerns lest he earn a reputation as a troublemaker, or — perhaps worse — someone who merely replicates and investigates others’ research rather than plant a flag of his own.

This criticism reminds me of similar points that were made at the International Studies Association’s annual convention last year. I answered to this criticism in my paper on replication in university teaching [pdf]:

Criticism 3: There could be reputational repercussions for young scholars if their first appearance in the “journal arena” is a paper that aims to denigrate “big names.” Such criticism seems patronizing. Introducing replication in the classroom ensures that students learn to conduct replication studies professionally, using adequate methods and language. I am not sure that the community really punishes replicators in the job market; if it does, then it must change. The answer cannot be to stop students from checking existing work. [[read more]:]

Why young scholars should replicate

Instead, we should remember all the reasons why young researchers can benefit from doing replication studies, which I summarized at my talk for the BITSS summer institute on transparency and reproducibility. [By the way, Brookmann was at the summer institute to report his experiences with replication.]

Janz Why replicate

I wrote about these reasons to replicate before, but it’s worth remembering them.

Here’s a few replication studies by students that show that replications are not a waste of time at all:
