Deception in animals is the voluntary or involuntary transmission of misinformation by one animal to another, of the same or different species, in a way that misleads the other animal. The psychology scholar Robert Mitchell identifies four levels of deception in animals.
Deception is a major relational transgression that often leads to feelings of betrayal and distrust. Deception violates relational rules and is considered to be a negative violation of expectations. Most people expect friends, relational partners, and even strangers to be truthful most of the time.
The Folly of Fools: The Logic of Deceit and Self-Deception in Human Life (2011, Basic Books, ISBN 0465027555) by Robert Trivers is a book that examines the evolutionary explanations for deceit and self-deception. Trivers focuses primarily on humans but he includes examples from many other organisms as well.
Acceptance of deception can be found in language terms that classify, rationalize or condemn, such behavior. Deception that may be considered a simple white lie to save feelings may me be determined socially acceptable, while deception used to gain certain advantages can be determined to be ethically questionable.
Tactical or functional deception is the use of signals or displays from an animal's normal repertoire to mislead or deceive another individual. [1] Some researchers limit this term to intraspecific behaviour, meaning that it occurs between members of the same species. [2]
By stotting (also called pronking), a springbok (Antidorcas marsupialis) signals honestly to predators that it is young, fit, and not worth chasing.. Within evolutionary biology, signalling theory is a body of theoretical work examining communication between individuals, both within species and across species.
Truth-default theory (TDT) is a communication theory which predicts and explains the use of veracity and deception detection in humans. It was developed upon the discovery of the veracity effect - whereby the proportion of truths versus lies presented in a judgement study on deception will drive accuracy rates.
Many insects including hoverflies (C, D, E) and the wasp beetle (F) are Batesian mimics of stinging wasps (A, B), which are Müllerian mimics of each other.. In evolutionary biology, mimicry is an evolved resemblance between an organism and another object, often an organism of another species.
