The current work identifies a so-far neglected bias in sequential impression formation. When the latent qualities of rivals are inferred from a cumulative sequence of observations (e.g., the sum of factors collected by sports activities groups), impressions ought to be based mostly solely on the newest commentary as a result of all earlier observations are redundant. Based mostly on the well-documented human incapacity to adequately low cost redundant info, we predicted the existence of a cumulative redundancy bias. Accordingly, perceivers’ impressions are systematically biased by the unfolding of a efficiency sequence when observations are cumulative. This bias favors main rivals and persists even when the tip results of the efficiency sequence is understood. We demonstrated this cumulative redundancy bias in eight experiments through which contributors needed to sequentially kind impressions concerning the qualities of two rivals from totally different efficiency domains (i.e., pc algorithms, shares, and soccer groups). We constantly discovered that perceivers’ impressions have been biased by cumulative redundancy. Particularly, impressions concerning the winner and the loser of a sequence have been extra divergent when the winner took an early lead in contrast with a late lead. When the sequence resulted in a draw, contributors shaped extra favorable impressions concerning the competitor who was forward throughout most observations. We examined and dominated out a number of different explanations associated to primacy results, counterfactual pondering, and heuristic beliefs. We focus on the wide-ranging implications of our findings for impression formation and efficiency analysis.
