Documenting being directive when offering forms to users
Problem
With https://gitlab.com/gitlab-org/design.gitlab.com/merge_requests/106 we are stating that all toggles should have a default option selected (which is good).
https://www.nngroup.com/articles/radio-buttons-default-selection/ offers some great information when to provide a default option and how it can be utilized to be directive to help the user.
Designs with a radio button selected by default make a strong suggestion—an endorsement even—to the user. The default choice may lead the user into making the best decision, and may increase his confidence as he proceeds. In particular, default radio selections can assist the person, and sway a person in the direction in which the organization wants him to go.
I think there is an opportunity here to document this explicitly for when designing settings and other forms pages
