Iceberg model

As explained in Collaborative Software Design: How to facilitate domain modeling decisions

A model of the mind that represents conscious, preconscious, and unconscious mental activity as levels with differing visibility and accessibility.

The iceberg model represents mental activity in three levels: conscious processes are visible and rationally accessible; preconscious memories become accessible through association; unconscious processes remain inaccessible but influence judgments, feelings, and behavior. section 4.3.1

Use the levels to notice what may be happening beneath visible group behavior:

  • Conscious: observable sensations and thoughts, such as noticing hunger and deciding to eat. section 4.3.1
  • Preconscious: stored memories and knowledge retrieved by association, such as a song recalling a holiday or a design recalling earlier practices. section 4.3.1
  • Unconscious: inaccessible processes that may shape behavior, including anxiety, conflict, frustration, and negative feelings. section 4.3.1

Making group shadows visible

During collaborative modeling, participants bring all three levels into the session. A facilitator can act like a flashlight, surfacing suppressed frustration or conflict before it grows into a larger problem. section 4.3.1

How Collaborative Software Design: How to facilitate domain modeling decisions covers it

How deep it goes
Defines three mental levels and applies them to group facilitation, but does not elaborate psychological mechanisms beyond their influence on behavior.
Examples
Uses hunger, music-triggered memories, architecture memories, and suppressed group frustration or conflict as examples.
What you can do after
Apply it via collaborative modeling facilitation to identify and address hidden tensions before they become larger group problems.
How it connects
Connects conscious, preconscious, and unconscious processes with mental models, collaborative modeling, facilitation, conflict, and group behavior.
