Are domesticated animals dumber than their wild relatives?

• Domestication is often thought to have a negative impact on the cognition of animals.

• Domesticated animals deemed less cognitively capable than their wild relatives.

• We reviewed 88 studies comparing cognitive abilities in domesticated and wild animals.

• No clear impact of domestication on cognition was found.

• Need to consider some constraints when interpreting domestication-cognition links.
