What you’ll be able to do

Explore and practice

Rewrite a trait judgment as an observation.
Identify a question that confirms an existing belief.
Identify when familiarity substitutes for evidence.
Use a four-part evidence note for an uncertain judgment.

What you can take into your work

Explain a response to each fictional case.
Use the job aid to prepare one proportionate action.
Distinguish an intended improvement from evidence that it occurred.

Complete the four-part evidence note for the fictional proposal, then select a review point tied to receipt of the missing approval.

The ambiguity check

A personal practice aid for voluntary learning; use fictional or nonidentifying details.

Examine how incomplete information becomes a confident judgment, and practice decisions that remain open to evidence.

Attend to observable actions and effects.
Do not infer another person's identity, motive, or IDI orientation.
Use established workplace support channels when a concern needs a formal response.

Complete the four-part evidence note for the fictional proposal, then select a review point tied to receipt of the missing approval.

Observation

What happened, and what source supports that description?
Remove trait labels and guesses about intent.

Interpretation

What explanation am I currently favoring?
What part rests on familiarity, background information, or style?

Alternatives

List two plausible explanations and evidence against your preferred one.
Apply the same task criteria across people and options.

Next evidence

Ask the narrow work-focused question that could change the decision.
State the decision, its uncertainty, and a concrete review trigger.

Complete a private practice note

Situation: describe the fictional case or a nonidentifying work process in two sentences. Separate what was observed from what remains uncertain. Do not include a colleague's private history or guess at an identity.
Response: write the actual words or process change you would use, identify the role that can act, and explain why the response fits the stated purpose.
Review: choose an ordinary observation that could show improvement, a point to reconsider the approach, and one possible unintended effect. A completed note shows preparation; only later evidence can show whether the action helped.

Participation and course completion in this program do not count toward DHS-required training credits unless management, a director, or DHS leadership expressly approves an exception.
