Scientific progress is like doing a puzzle, not building a wall

  • Alexa M. Tullett (a1) and Simine Vazire (a2)

Abstract

We contest the “building a wall” analogy of scientific progress. We argue that this analogy unfairly privileges original research (which is perceived as laying bricks and, therefore, constructive) over replication research (which is perceived as testing and removing bricks and, therefore, destructive). We propose an alternative analogy for scientific progress: solving a jigsaw puzzle.
