Systems and methods are provided for automatically recommending content. One example method includes receiving, from a computing device, a request for content and generating an initial result set in response to the request. A user profile associated with the request is identified. Based on the initial result set and the user profile, a positivity index score for the initial result set is determined. Based on the positivity index score, a type of additional content to add to the initial result set is determined. A modified result set is generated by adding the additional content to the initial result set. At least a portion of the modified result set is transmitted to the computing device.
