Selective BTS initiatives (arranged alphabetically). For each initiative, we approximated the percentage of authors who contributed to each aspect of the project by having two researchers (H.A.B. and N.A.C.) code the author contributions for each paper. For each project, darker shades indicate that a relatively high percentage of authors reported contributing to each aspect of the project. Citations in figure refer to [9,12–14,22]. Coding information used to generate this figure is available at https://osf.io/2p4ct/.
