There is relative paucity in the comprehensive study of anger and information processing. Emotions can impact the depth of information processing and anger is a powerful high-certainty emotion. Yet, the magnitude of the effects of anger on the depth of information processing has not been summarized. This scholarship performs a meta-analytic synthesis to report the effect of anger on the depth of information processing as compared to one of the four contrast groups: neutral control, sadness, happiness, and fear. A systematic search identified 26 articles with a total of 39 unique studies and 113 effect sizes. The evaluation revealed that anger did not have a significant effect on depth of information processing for any of the emotional comparison groups. Furthermore, the presence of publication bias was only found for one analysis. These complex results indicate that anger is an exceedingly nuanced emotion. The implications of the study and future scholarship are discussed.
