Comparison

Soft vs hard laddering

Comparison of soft laddering, which follows the conversation, with hard laddering, which completes each attribute, consequence and value chain in turn.
Hard laddering gives you chains you can compare across participants, which matters once you code 20 or more interviews.

The two forms of the laddering interview side by side. Soft laddering follows the conversation and probes when an opening appears, which gives richer data but needs a skilled interviewer. Hard laddering follows a protocol that completes each attribute, consequence and value chain before moving on, so answers compare cleanly across participants. Koji's AI interviewer is built for hard laddering, probing every open answer to the same depth.

Where this appears

What's in this comparison

Soft laddering

  • Lets the conversation set the order
  • Probes follow threads as they come up
  • Richer, more natural data
  • Needs an experienced interviewer

Hard laddering

  • Follows a structured protocol
  • Completes each A-C-V chain before the next attribute
  • More consistent data across participants
  • Suits newer interviewers and AI moderation at scale
