Deciding with incomplete information: what do you actually need to find out?

Name a particular action and a question whose answer could change its conditions. Distinguish fact from preference, checking from assumption and a negative answer from no answer. Retain remaining uncertainty.

Questions explored

Must everything be known before choosing?

The article considers information for a particular step, without promising complete certainty.

What does a trial confirm?

Only an action or assessment under stated conditions; it does not establish the entire future experience.

What is the exercise’s result?

A clearer question and boundary of the answer; deciding, messaging or purchasing are optional.

Key distinctions

Lee and Shachter distinguish personal distinctions clear to an individual from shared distinctions clear to several participants. (Lee/Shachter selected§§4.1–4.2)

The source’s imagined all-knowing observer aids model clarification, rather than supplying a real ability to know the future. (Lee/Shachter selected§5.1)

In the fictional scene, an unknown property, personal criterion and another person’s future response need different answers. (United Wisdom, fictional Marta)

A negative answer differs from an answer not received. (United Wisdom)

Additional searching takes time and need not resolve a difficulty about preference. (United Wisdom)
