Our reading
An editorial interpretation.
A political leader warns that genuine danger comes not from admitting uncertainty, but from false confidence held by decision-makers who wrongly believe they understand a situation. Acting decisively on flawed assumptions is described as far riskier than acknowledging the limits of one's own knowledge in complex matters.
