Showing anger during a negotiation may increase the ability of the anger expresser to succeed in negotiation. A study by Tiedens et al. indicated that the anger expressers were perceived as stubborn, dominant and powerful. In addition, it was found that people were inclined to easily give up to those who were perceived by them as powerful and stubborn, rather than soft and submissive. Based on these findings Sinaceur and Tiedens have found that people conceded more to the angry side rather than for the non-angry one.
