While managing private data in cognitive surveys, a method, system, and computer program product may deploy a set of gather agents. Access credentials for a plurality of participants may be obtained from an encrypted data store and verified. The set of gather agents may gather a set of target data associated with the plurality of participants, and the set of target data may be collected according to a set of policy criteria. It may be determined whether one or more participants of the plurality of participants has requested to review a subset of the target data, and those participants may be prompted to review the subset of target data. It may be determined whether the one or more participants rejected the subset of target data. The subset of target data may be filtered, and the filtered subset of target data may be posted to a results database.
