Methods and systems for distributed cognition of digital content include receiving submissions from community members regarding a knowledge object. Each community member has a reputation value and each submission includes an evaluation value representing an evaluation of the knowledge object by the community member. A consensus evaluation is determined based on a calculated combination of the evaluation values in the submissions received and the reputation values of the respective community members who submitted the submissions. While submissions are being received, the consensus evaluation of the knowledge object is iteratively updated based on submissions received, being a calculated combination of the evaluation values in the submissions received and the reputation values of the respective community members who submitted the submissions. Additionally, the reputation value for each community member who submitted the submissions is iteratively updated based on a determined contribution of the respective community member's submission to the updated consensus evaluation.
