Which directive primarily emphasizes expressing uncertainties in analytic judgments?

The directive that primarily emphasizes expressing uncertainties in analytic judgments is Intelligence Community Directive 203. This directive focuses on the need for analysts to acknowledge the limitations of their information and the uncertainties associated with their assessments. By doing so, it enhances the transparency of analytic processes and allows decision-makers to better understand the confidence level of intelligence reports.

Intelligence Community Directive 203 specifically outlines the standards for the production of intelligence, which includes a structured approach to articulating uncertainty. This is important because it helps to ensure that decision-makers are fully aware of the potential risks involved in the actions taken based on intelligence assessments.

In contrast, other options like Intelligence Community Directive 206, while also relevant to the intelligence community, are centered around different aspects such as the role of executive oversight and the requirements for the evaluation and management of intelligence activities. Imagery Exploitation Support System and Remote Replication System refer to specific systems and technologies used in imagery analysis and data handling, rather than addressing the principles of expressing uncertainties in analytic judgments.
