Phys.org / Honest or deceptive? What a new signaling model means for animal displays and human claims

For decades, scientists have tried to answer a simple question: why be honest when deception is possible? Whether it is a peacock's tail, a stag's roar, or a human's résumé, signals are means to influence others by transmitting ...
