Jeff Belkora developed S5 in the context of helping people make medical decisions. The model also applies to choices in other domains, such as personal and professional decisions.

S5 refers to five sources of insight or guidance in arriving at a decision:

  1. Somatic
  2. Social
  3. Spiritual
  4. Soulful
  5. Scientific

Each of these sources will influence people's decisions and actions.

Being aware of these sources can help people communicate about them to arrive at clear, confident, and consensus-based decisions - or to surface necessary conflict.
