Working on: the consequences of release and management of gamebirds; the evolution of cognition, using the genius of the bird world - pheasants; and occasionally messing with chickens, ravens, beavers and moths. Tweets by Jo Madden

How does cognition determine an individual’s fitness? A systematic review of the links between cognition, behaviour and fitness in non-human animals | Philosophical Transactions of the Royal Society B: Biological Sciences
Recent efforts to understand the evolution of cognition have adopted a within-species approach where cognitive performance, and its effects on behaviour, is correlated with fitness benefits and, if related, is assumed to be selected for. We reviewed 45 ...

Why is the apparent link between cognition and fitness so weak?
Could it be that our proposed causal link between cognition, behaviour and fitness/selection is too simplistic and linear? We discuss possible alternative models

Studies that measured fitness as "survival" (survival to next season, mass gain, foraging success etc) were more likely to report sig relationships than those measuring "reproductive" fitness (attractiveness, provisioning levels, offspring production etc)

Studies that measured "broad" forms of cognition (innovation, problem solving) were more likely to report sig relationships than those measuring more "specific", defined forms (reversal learning, spatial memory etc)

Studies using larger sample sizes were LESS likely to report a significant relationship

Positive relationships (‘smarter is better’) outnumbered negative ones (‘dumber is better’) among the significant results, but these still comprised >20%
Selection might reduce cognitive performance as well as enhance it
