This component contains information regarding the literature search (i.e., systematic review). The file called **Search results.xlsx** contains all 155 records identified as potentially relevant to be examined further. It contains the results from searches using Google Scholar (tab called google) and EBSCO (tab called ebsco). The tab called combined contains the unique records (128 in total) from both searchers combined and assigns a unique identifier to each record. Finally, the tab called references_coded contains all relevant references identified in those 128 records. In total, 31 records were identified in this way, four of which were already in the initial list of 128 (indicated by the AlreadyInList variable). As such, 128 + 27 gives the 155 records that were then coded. The file called **Multiverse Literature Coding Form.pdf** shows a printout of the Google Form we used to code the records identified as potentially relevant. The file **Multiverse Literature Coding Form.csv** contains the data from this coding process, which are analyzed in the R script called **Multiverse Literature Coding Form.R**. This script contains some additional comments describing the coding process as well as the descriptives of Figure 2 (which are hardcoded in the manuscript). The 34 records that met all inclusion criteria were subsequently coded to extract the data-processing pathways. This was done via a Google Form, a print of which can be found in the file **Multiverse Pipeline Coding Form.pdf**. The raw outcomes of that coding process can be found in **Multiverse Pipeline Coding Form (Responses).xlsx**, which were then grouped in categories (see **Code book review filled literature.xlsx**).
