What determines decision quality?

Category: Research · Status: Published · June 2026

Question

If decision quality should not be evaluated solely by outcomes, a further question emerges:

What determines the quality of a decision?

Can decision quality be assessed before the outcome becomes known?

If so, what factors should be considered?

Observation

People often judge decisions after results are known.

However, outcomes may be influenced by randomness, incomplete information and external events.

Two individuals can make identical decisions and receive different outcomes.

This suggests that outcome quality and decision quality may not always be identical.

If decision quality exists independently of outcomes, it must depend on something available at the moment the decision is made.

Interpretation

Several candidate factors emerge:

• quality of available information
• relevance of available information
• consideration of uncertainty
• evaluation of alternatives
• reasoning process
• risk assessment
• awareness of assumptions

A decision process that systematically incorporates these elements may be of higher quality than one that does not.

This does not guarantee a better outcome.

However, it may increase the probability of making sound decisions.

Current Position

EdgeLab currently does not know which factors are most important.

However, the observations suggest that decision quality may be linked to the quality of the information and reasoning process available before the outcome occurs.

A working hypothesis emerges:

This hypothesis remains unvalidated.

Next Question

If information quality influences decision quality, a further question follows:

This question will be explored in future research.
