In an example, a method includes determining an external quality metric for cohort data by comparing the cohort data with externally available data for persons who are members of the cohort; determining a confidence metric for the cohort data according to a variability between the cohort data and ground truth data; determining a member accuracy metric by requesting evaluation of the cohort data by members of the online social networking service; normalizing each of the metrics to a predetermined numerical range; retrieving a weight for each of the external quality metric, the confidence metric, and the member accuracy metric; filtering the cohort data according to a convex combination of the external quality metric, the confidence metric, and the member accuracy metric with their respective weights; and suppressing display of the cohort data in response to the filtered information for the cohort indicating that the convex combination traverses a threshold value.
