 For example, what Ekman would describe as an anger face, a sad face or a happy face is described by behavioral ecologists as, respectively, a display of readiness to attack, a display of intent to affiliate and a display of recruitment of succor (Fridlund 1994). A number of theorists have argued that Ekman’s and Fridlund’s approaches can be reconciled: emotions can at the same time express emotions and make declarations that are credible precisely because they are associated with emotions (M. Green 2007; Scarantino 2017; Hess, Banse, &amp; Kappas 1995; see also Bar-On 2013).
