Abstract The handicap principle was originally proposed to resolve the question of why, in their competition for mates, certain species invest in exaggerated ornaments that are often detrimental to their survival. Zahavi suggested that the traits that are most suitable to serve as signals are precisely those that require the burden of extra investment to increase in magnitude: that burden enables the signal to be correlated with the signaler’s quality. According to his model, the additional investment in signaling results in a functional advantage. It does so by providing more accurate information regarding the signaler as it increases the distinction between males of similar quality. There are a number of formalizations of this model, and experimental studies of the handicap principle have focused on testing them. Nonetheless, there is little consensus whether 1) ensuring reliability requires an additional investment or 2) traits that require a relatively higher investment to increase (have higher marginal costs) are selected as signals over those with lower marginal costs. Here, we present an agent-based mate choice model that quantifies the relative stability of signals with different marginal costs. Our model demonstrates how quality-independent constraints (in signal production and perception) affect the range of marginal costs for which a signal is informative. In turn, receiver preference for informative signals drives the selection of signals according to marginal cost. The presence or absence of signaling constraints can determine the outcome of costly signaling models and, thus, explain the different conclusions of Zahavi’s verbal model and its subsequent formalizations.

Sense And Sensibility

‘Pray, pray be composed,’ cried Elinor, ‘and do not betray what you feel to every body present. Perhaps he has not observed you yet.’ For Elinor Dashwood, sensible and sensitive, and her romantic, impetuous younger sister Marianne, the prospect of marrying the men they love appears remote. In a world ruled by money and self-interest, the Dashwood sisters have neither fortune nor connections. Concerned for others and for social proprieties, Elinor is ill-equipped to compete with self-centred fortune-hunters like Lucy Steele, whilst Marianne’s unswerving belief in the truth of her own feelings makes her more dangerously susceptible to the designs of unscrupulous men. Through her heroines’ parallel experiences of love, loss, and hope, Jane Austen offers a powerful analysis of the ways in which women’s lives were shaped by the claustrophobic society in which they had to survive.
