CORE DEFINITION

When faced with multiple hypotheses that can explain a phenomenon, choose the one that is the most explanatory, simplest, and most consistent with background knowledge. (For example, if the grass is wet, it could be due to rain or a sprinkler. If the roof is also wet, the best explanation is rain).

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Detective thinking. When information is insufficient, do not pursue absolute deduction. List all possibilities, score each one, and choose the one that 'makes the most sense' as the basis for action.

anchor

Anchor fast decisions

That is, abductive reasoning: among multiple conclusions that can explain the evidence, choose the 'best explanation'—typically combining simplicity, broad coverage, and plausibility. The mechanism is plausibility competition.
