1. A system comprising:

  • a data analyzer to determine a first plurality of responses a first viewer has to a first event and a second event of media based on first physiological response data obtained from the first viewer while exposed to the first and second events, the data analyzer to determine a second plurality of responses a second viewer has to the first event and the second event of the media based on second physiological response data obtained from the second viewer while exposed to the first and second events;

    a coherence module to;

    calculate a first coherence value for the first event based on a first degree of similarity between (1) the responses of the first viewer and (2) the responses of the second viewer occurring during the first event, the first coherence value having a first value when the first and second plurality of responses occurring during the first event are similar and the first coherence value having a second value lower than the first value when the first and second plurality of responses occurring during the first event are not similar; and

    calculate a second coherence value for the second event based on a second degree of similarity between (1) the responses of the first viewer and (2) the responses of the second viewer occurring during the second event; and

    a rating module to at least one of rate the first event based on the first coherence value, rate the second event based on the second coherence value or rate the media based on the first coherence value and the second coherence value.
