Bringing more female and non-binary voices into Token Engineering will support the development and design of public goods/systems which have a more holistic impact on society. 
These key systems thinking principles highlight why the gender gap impacts the design of public systems:
Holism: The idea that systems are more than the sum of their parts, and should be studied as a whole. 
This means to understand a system and the actors it serves, the design of the system should be undertaken by the range of actors who will take part. 
Reflexivity: The recognition that the observer or designer is part of the system and can influence its behaviour. 
To have a male-dominated design team will only perpetuate biases in objective setting and incentive design. 
Perspectives: The understanding that different people have different perspectives and experiences of a system, and that these perspectives can shape its behavior and outcomes.
