An example relates to survey analysis, survey panel members analysis, accuracy metrics, reliability analysis, and statistical analysis, to come up with confidence levels, and get an overall reliability of survey panel members, based on a score and percentile, and give incentives to the panel members, based on their reliability scores, to encourage them to be more reliable and truthful in the surveys, including their background and their demographics, increasing the values of the survey results drastically. In addition, this covers many separate embodiments: methods for improving and “incentivizing” truthful behavior in consumer panels; using Trustscore to measure and reward consistency and truthfulness; tag surveys to segment panels; and Doublecheck'd as a tool, to utilize the best responses through asking panel members twice (or more) with the same survey, and only including results from the members who answer the same both (or more) times.
