Human Agency Scale (HAS)

A five-level scale quantifying the degree of human involvement required for AI-assisted task completion:

  • H1: AI agent handles the task entirely on its own
  • H2: AI agent needs minimal human input for optimal performance
  • H3: AI agent and human form equal partnership, outperforming either alone
  • H4: AI agent requires human input to successfully complete the task
  • H5: AI agent cannot function without continuous human involvement

Unlike SAE driving automation levels (which adopt an “AI-first” perspective), HAS provides a human-centered lens. Higher levels aren’t inherently better, different levels suit different contexts. H1-H2 tasks favor automation approaches; H3-H5 tasks benefit from augmentation strategies.
