Ethics

Most threats overlap. A family relationship can give rise to a familiarity threat (eg you might be inclined to trust a family member too much). However, it can also give rise to a swlf interest threat because you don't want to fall out with a relative and are anxious tomstay on good terms. It can also even cause an intimidation threat. Eg your big brother bullied you as a child and that domineering relationship continues into adulthood.
