A premature consensus: are happiness and sadness truly opposite affects?

Within the debate on the structure of affect, a consensus began emerging in the last decade regarding the bipolarity of happiness–sadness. We argue that this consensus is premature. Focusing on the psychometrics of momentary affect, particularly happiness and sadness, and using a simulation study, a large-scale data set, and 2 experiments manipulating affect, we plot a map of affective space that departs from the consensus. One key departure is the finding that happiness and sadness are not bipolar opposites. Another is that nonuniform skewness plays a major role in studies of affective structure, but can be addressed with appropriate analyses.
