If you’ve ever gotten the death glare from your parent, child or S.O., you already know the results of this new study to be true.
New research in the journal Psychological Science shows that people are more likely to give in to an unfair demand when they are presented with a threatening facial expression.
For one of the experiments in the study, 870 people played a negotiation game, which involved deciding how to split $1 between two people. In each scenario, there was a “proposer,” who decided how the dollar would be split and a “responder.” However, before making the decision, the proposer was shown a video clip of the responder making either a neutral facial expression or an angry one. (Little did the study participants know, the responder was actually an actress who was instructed to portray a certain facial expression in each scenario).
In addition to viewing the facial expressions of the responder, the proposer received a written demand from the responder for either half of the amount (considered a “fair” request), or 70 percent of the amount (an “unfair” request). If the responder didn’t accept the proposer’s deal, neither party would get the money.
Researchers found an association between the offer made by the proposer and the facial expression of the responder. If the responder made an angry face and requested the 70 percent, the proposer was more likely to give the 70 percent.
Meanwhile, if the responder made an angry face and only requested the 50-50 split, this didn’t seem to affect how much the proposer offered, likely because the request was already deemed fair. (Something to consider: Because a woman actor was used for the experiment and female and male anger can be perceived differently, the results of the study apply only in the context of a woman’s angry facial expressions being able to influence giving into an unfair demand.)
Of course, anger is just one of the many expressions our faces are capable of making. HuffPost Science previously reported that our faces are actually capable of expressing21 different emotions —- including “sadly angry” and “happily disgusted.”
