One of the strengths in the Intelligent Design movement is its close, conceptual proximity to common sense and scientific procedure in other fields of inquiry. In other words, we are naturally and deliberately always looking for order in things and inferring intelligence: archeology, information theory, freshman ethics papers, etc.
If the premises behind ID are wrong, why did NASA beam a couple of Beatle’s songs into the cosmos? Why not utterly random, meaningless noise? Why not just a simple, repeatable pulse? Because we know there is a substantial, even meaningful, difference between naturally produced phenomena and the artifacts of intelligence.
Even though the current scientific community continues to cudgel ID in the press, it relies on its basic principles to perform its most basic of tasks.
