Document Summary
Arrive at prediction about bias in perception of distance and steepness of things. Fitness cost associated with falling from steep edges. Over-estimate of vertical height, especially when looking down. More energy, more capable of navigating this steep place, the. Anticipated energetic costliness influences perception of distance. Adapted cognition doesn"t equal to accurate cognition. Cognitive biases -- behavioural decisions -- fitness implications. Within the eea, there"s a potential to make different kind of judgment. Error is associated with different fitness costs. Natural selection favour the evolution of certain kinds of cognitive biases. That minimize the likelihood of making especially costly errors. That can have the consequence of making more and more errors of other kinds. Want the smoke detector that are over sensitive. Make tons of mistake but non catastrophic. Different fitness costs associated with false alarm . Typically in situation involved threat & danger, failure to recognize the more costly error/miss.
