Prof. Allen MacNeill has been arguing on his blog, that Intelligent Design Theorists (IDT) have fallen into the fallacy of inferring design to objects that in actuality, have no teleology at all. He hypothesizes the vertebrate mind is composed of modules. One of these modules is a highly effective intentionality detector.
In support of this argument, he uses an example from his student’s paper in the Cornell ID class. Allen writes,
As Broaddus points out, one of the side-effects of such an “agency detector” would be the detection of intentionality in entities that clearly had no such intentions. If, for example, one of the most important functions of such a detector in humans is to quickly “read” and assess the intentions betrayed in human facial expressions, then it would almost certainly detect human facial expressions in objects in the environment that clearly do not have such expressions, such as rocks, foliage, water stains, etc
Allen continues his argument with this example.
