The researchers found that the most informative indicator of gender ratio of society boards and leadership positions was a cultural model, which included the age of the society, size of its board and whether or not a society had an outward commitment or statement of equality. Models that focused on geographic location or study discipline were less informative when it came to gender ratio.

The researchers' findings suggest that women may be more highly represented in smaller societies with at least one woman in a leadership position. However, this representation still falls far short of equal (~30%). To promote gender equity within academic societies, researchers recommend a push to increase female leadership and including a constitutional commitment to equality, such as a statement of support.
