1. Design Detection
If nature, or some aspect of it, is intelligently designed, how could we tell?
Design inferences in the past were largely informal and intuitive. Usually people knew it when they saw it. Intelligent design, by introducing specified complexity, makes the detection of design rigorous. Something is complex if it is hard to reproduce by chance and specified if it matches an independently given pattern (an example is the faces on Mt. Rushmore). Specified complexity gives a precise criterion for reliably inferring intelligence.
2. Looking for Design in Biology
Should biologists be encouraged to look for signs of intelligence in biological systems? Why or why not?
Scientists today look for signs of intelligence coming in many places, including from distant space (consider SETI, the search for extraterrestrial intelligence). Yet, many biologists regard it as illegitimate to look for signs of intelligence in biological systems. Why arbitrarily exclude design inferences from biology if we accept them for other scientific disciplines? It is an open question whether the apparent design in nature is real.
