Figure 1.

Ten reasons to replicate simulation studies. Image description: The figure shows 11 boxes. Each box contains one of the reasons to replicate simulation studies together with an icon visualizing the corresponding reason. (1) Major impact: A megaphone with arrows pointing to articles; (2) Conflict of interest: A face critically glancing to the side; (3) Selective reporting: A puzzle with a missing piece; (4) Competing aims: Two bulls' eyes, one of them with an arrow in the center; (5) Coding errors: A bug; (6) Limited scope: A spotlight; (7) The devil is in the detail: The last two letters of “detail” are replaced with a tiny devil; (7) A chance to learn: A pile of books with a graduation cap on top; (8) Leading by example: three stick figures marching behind each other, the first one carrying a road sign; (10) Because we can: A figure with four arms; (11) (Bonus reason) Conceptual replications: A star and two easels, each easel carrying a picture of a different star.
